1. SAFETY
1.1 GENERAL
SULLAIR manufactures all of its products so they can be operated safely.
However, the responsibility for safe operation rests with those who use
and maintain our products. The following safety precautions are offered
as a guide which, if conscientiously followed, will minimize the possibility
of accidents throughout the useful life of this equipment.
This compressor should be operated only by those who have been
trained and delegated to do so, and who have read and understand the
Operator’s manual. Failure to follow the instructions, procedures and
safety precautions in the manual may increase the possibility of accidents
and injuries.
Never start this air compressor unless it is safe to do so. Do not attempt
to operate the air compressor with a known unsafe condition. Tag the air
compressor and render it inoperative by disconnecting and locking out all
power at source or otherwise disabling its prime mover so others who
may not know of the unsafe condition cannot operate it until the condition
is corrected.
Install, use and operate this air compressor only in full compliance with all
pertinent ISO regulations and all applicable. Local codes, standards and
regulations.
Do not modify this compressor and/or controls in any way, except with
written factory apporval.
While not specifically applicable to all types of compressors with all types
of prime movers, most of the precautionary statements contained herein
are applicable to most compressors, and the concepts behind these
statements are generally applicable to all compressors. Carry out a daily
compressor control and check for leaks, loose or missing components
and for any damaged or misadjusted parts.
Personal protective equipment:
Prior to installing or operating this compressor, owners, employers, and
users should become familiar with, and comply with, all applicable regu-
lations, and any other applicable Local codes, standards, and regulations
relative to personal protective equipment, such as eye and face protec-
tive equipment, respiratory protective equipment, equipment intended to
protect the extremities, protective clothing, protective shields and barri-
ers, and electrical protective equipment, as well as noise exposure ad-
ministrative and/or engineering controls and/or personal hearing
protective equipment.
Before any high pressure cleaning, electrical parts must be protected.
1.2 TOWING
A. PREPARING TO TOW
1. Inspect the ball hitch, pintle eye, coupling device and drawbar and
chains (if requested) and also the coupling device of the towing vehi-
cle and if to be used, the chain attachment points: then check for any
defects such as wear or excessive corrosion, or cracked, bent,
dented or otherwise deformed or degraded parts as well as for loose
nuts and bolts or other fixings the compressor and towing vehicule
must be in horizontal position.
Do not tow until all these problems have been solved.
2. Reverse the towing vehicle to the compressor and position it in prep-
aration for coupling with the compressor set the tow bar in order that
the coupling device of the compressor is horizontal.
3. Verify that the coupling device is fully engaged, closed and locked.
4. If chains are requested, pass each chain through its attachment point
on the towing vehicle, then hook each chain to itself by passing the
grab hook over (not through) a link.
5. Make sure that the coupling device and adjacent structures on the
towing vehicle and also, if requested, the chain adjustments, brake
and/or electrical interconnections do not interfere with or restrict the
movement of the compressor, including its coupling device, with
respect to the towing vehicle, when maneuvering over any antici-
pated terrain.
6. If requested, ensure that the chain lengths, brake and electrical cir-
cuit interconnections provide sufficient slack to prevent strain when
maneuvering or negotiating a bend. Make sure however that they are
sufficiently supported so they cannot drag or rub on the road, terrain
or towing vehicle surfaces which might cause wear and render them
inoperative.
7. Fully retract the front screw jack. If a castor wheel is provided,
remove the lock pin and fold and raise the castor wheel; then make
sure the pin is re-engaged and secures the castor wheel in full up and
locked position with the wheel horizontal.
8. Make sure that tyres are in good condition, of the correct size (load
range), and inflated to the correct pressure. Never change the type of
size of tyre. Check that the pivots, fixing screws and wheels are tight-
ened to correct torque.
9. If provided, make sure that the dual stop, tail, fog, directional and
clearance lights function correctly and that their lenses are clean and
functional. Also check that all reflectors and reflecting surfaces are
clean.
10.Make sure that all service air hoses (not air brake hoses) are discon-
nected or are fully stowed and secured on hose reels if provided.
11.Check that all access doors and tool box covers are closed and
latched. If the compressor is large enough to hold a man, make sure
all personnel are out before closing and latching access doors.
12.Make sure that the towing vehicle’s parking brake is set, or that its
wheels are chocked or blocked or that it is otherwise stopped from
moving. Then release the compressor parking brakes if provided.
13.Make sure that the compressor wheels are not chocked or blocked
and that any fixings are free.
14.Test overrunning brake operation, including the emergency brake
functioning, if provided, before attempting to tow the compressor at
permissible speed.
15.Do not carry loose or badly stowed tools, equipment or supplies on or
in the compressor.
B. TOWING
1. Observe all motor vehicle regulations in force, including those speci-
fying speed limitations.
2. Under ideal conditions, tow at the speeds recommended or lower.
Reduce speed according to road signs, weather, road or terrain con-
ditions.
3. Remember that portable air compressors may approach or exceed
the weight of the towing vehicle. Therefore increase braking dis-
tances accordingly.
4. Avoid gradients in excess of 27% (15°).
5. Avoid pot-holes, rocks and other obstructions, and soft shoulders or
unstable terrain.
6. Manoeuvre in a way that will not exceed the freedom of motion of the
compressor’s draw-bar and/or coupling device in or on the towing
vehicle’s coupling device and/or the adjacent structures, whether
towing forward or backward, regardless of the terrain being tra-
versed.
7. Do not allow personnel to ride on the compressor.
8. Make sure before maneuvering that no personnel or obstructions are
behind or under the compressor.
9. Do not allow any personnel to stand or ride on the drawbar, or to
stand or walk between the compressor and towing vehicle.
C. PARKING OR LOCATING COMPRESSOR
1. Park or locate the compressor on level ground if possible. If not, park
or locate it across the gradient so the compressor does not tend to
roll downhill. Never park or locate the compressor on gradients
exceeding 27% (15°).
2. Check that the compressor is parked on a firm surface that can sup-
port its weight.
3. Park the compressor so that the wind, if any, tends to carry the
exhaust gases and radiator heat away from the compressor air inlet
openings and so that the compressor is not exposed to excessive
dust from the work site.
4. Set parking brake and disconnect the emergency switch cable as
well as all other electrical interconnections and/or brake circuit con-
nections, if provided.
5. Check or block both sides of each wheel.
6. If provided, unhook the chains and remove them from the chain
attachment points of the towing vehicle. Then hook the chains onto
the ball on the drawbar or wrap chains around the drawbar and hook
them to themselves to stop the chains resting on the ground, which
may cause rusting.

1. SAFETY

7. If provided, lower the screw jack or stabilizer legs. Make sure the
contact surface has sufficient load bearing capacity to support the
compressor weight.
8. Move the towing vehicle well clear of the parked compressor, and
erect danger indicators, barricades and/or lighted markers (at night)
when the compressor is parked on or adjacent to public roads. Park
to avoid traffic interference.
* Many of these recommendations also apply to mobile air compressors
mounted on feet, even though they are not towed in the true sense of the
word.
1.3 PRESSURE DANGERS
A. Open the pressure relief valve at least once per week to ensure it is
neither blocked, closed, obstructed or otherwise damaged.
B. Do not use tools that are rated below the maximum rating of this com-
pressor. Select tools, air hoses, pipes, valves, filters and other fittings
accordingly. Do not exceed manufacturer’s rated safe operating pres-
sures for these items.
C. Secure all hose connections by wire, chain or other suitable retaining
devices to prevent tools or hose ends from being accidentally discon-
nected.
D. Open fluid filler cap only when compressor is not running and is not
pressurized. Shut down the compressor and bleed the sump (receiv-
er) to zero internal pressure before removing the cap.
E. Vent all internal pressure prior to opening any line, fitting, hose, valve,
drain plug, connection, or other components, such as filters and line
oilers, and before attempting to refill optional air line anti-icer systems
with antifreeze compound.
F. Keep personnel out of line with and away from the discharge opening
of hoses, tools, or other points of compressed air discharge.
G. Use air at pressures less than 207kPa (2 bar) for cleaning purposes,
and then only wih effective chip guarding and personal protective
equipment.
H. Do not engage in horseplay with air hoses, as death or serious injury
may result.
I. Wait until the radiator has cooled down. Then unscrew the cap slowly
to its stop to relieve any excess pressure, and check that the coolant
is not boiling prior to removing the cap completely.
1.4 FIRE AND EXPLOSION
A. Refuel at a service station or from a fuel tank designed for that pur-
pose. If this is not the case, ground the machine to the dispenser be-
fore refuelling.
B. Clean up spills-of lubricant, or other combustible substances immedi-
atly when such spills occur.
C. Shut off the air compressor and allow it to cool. Then keep sparks,
flames and other sources of ignition away and do not permit smoking
in the vicinity when checking or adding lubricant, or when refilling air
line anti-icer systems with antifreeze compound.
D. Do not permit liquids, including air line anti-icer system antifreeze
compound or fluid film to accumulate on bottom covers or on, under or
around acoustical material, or on any external surfaces of the air com-
pressor or on internal surfaces of the enclosure. Wipe down using an
aqueous industrial cleaner or steam clean as required. If necessary,
remove acoustical material, clean all surfaces and then replace
acoustical material. Any acoustical material with a protective covering
that has been torn or punctured should be replaced immediately to
prevent accumulation of liquids or fluid film within the material do not
use flammable solvents for cleaning purposes.
E. Disconnect and lock out all power at source prior to attempting any re-
pairs or cleaning of the compressor.
F. Keep electrical wiring, including all terminals and other pressure con-
nectors in good condition. Replace any wiring that has cracked, cut,
abraded or otherwise degraded insulation ; or terminals that are worn,
discolored, or corroded. Keep all terminals and pressure connectors
clean and tight.
G. Switch off the battery charger or break the connections to it, before do-
ing any repair work or cleaning.
H. A conducting object like a iron tool can create a short circuit through
contact between (+) (eg: terminal (+) of the battery) and the earth, that
could provoke an electric arc with burns and fire risk.
I. Replace damaged tanks or fuel lines immediately, rather than trying to
weld or otherwise repair them. Do not store or try to run the compres-
sor if there are any known leaks in the fuel system.
J. Before a welding repair operation, remove any acoustical material or
other material that may be damaged by heat or that may support com-
bustion and is in close proximity prior to attempting weld repairs.
K. Keep a suitable full charged class BC, ABC or the ones requested in
your country fire extinguisher, or extinguishers, nearby when servicing
and operating the compressor.
L. Keep oil rags, trash, leaves litter or other combustibles away from the
compressor.
M. Open all acces doors and let vent the compressor prior to starting in
order to avoid possible presence of vapor.
N. Do not operate the compressor under low branches and ensure that
the leaves are not in contact with hot exhaust system surfaces when
operating in forested areas.
O. The anti-freeze used in certain air line anti-ice systems contains meth-
anol, which is inflammable. Only use and refill these systems with an-
tifreeze in well ventilated areas, away from heat, bare flames or
sparks. Do not expose any part of these systems or the antifreeze to
temperatures above 66°C. The antifreeze vapours are heavier than
air. Do not store this product or discharge treated air in confined or un-
ventilated areas. Do not store containers or antifreeze in direct sun-
light.
P. Storeallfluids andinflammablematerials wellaway from your work ar-
ea. Know where fire extinguishers are placed, how to use them and
for what type of fire they are intended. Check the condition of fire fight-
ing systems and detectors if so equipped.
1.5 MOVING PARTS
A. Keep hands, arms and other parts of the body and also clothing away
from fans, and other moving parts.
B. Do not attempt to operate the compressor with the fan or other guards
removed. ( belt guards).
C. Wear snug fiting clothing and confine long hair when working around
the compressor, especially when exposed to hot or moving parts.
D. Keep access doors, if any, closed except when making repairs or ad-
justments.
E. Make sure all personnel are out of and/or clear of the compressor prior
to attempting to start or operate it.
F. Shut off engine before adding fuel, oil, coolant, lubricants and airline
antifreeze or battery electrolyte or before replacing ether starting aid
cylinders.
G. Disconnect the grounded negative battery connection before carrying
out any repairs or adjustments to avoid accidental engine operation.
Tag the battery connection so that others won’t unexpectedly recon-
nect it.
H. Keep hands, feet, floors, and walking areas clean and make sure they
are free from oil, water, antifreeze or other liquids, to minimize the
risks of slips and falls.
1.6 HOT SURFACES, SHARP EDGES AND SHARP
CORNERS
A. Avoid bodily contact with hot fluid, hot coolant, hot surfaces and sharp
edges and corners.
B. Keep all parts of the body away from all points of air discharge.
C. Wear personal protective equipment, including gloves and head cov-
ering, when working in, on, or around the compressor.
D. Keep a first aid kit handy. Seek medical assistance promptly in case
of injury. Don’t ignore small cuts and burns as they may lead to infec-
tion.
1.7 TOXIC AND IRRITATING SUBSTANCES
A. Do not use air from the compressor for respiration (breathing) except
in full compliance with CEE Standards and any other Local codes or
regulations.
B. Operate the compressor only in open or well ventilated areas.

1. SAFETY
S65 II

E
C. Locate the compressor or provide a remote inlet so that it is not likely
to ingest exhaust fumes or other toxic, noxious or corrosive fumes or
substances.
D. Locate the compressor so that the exhaust gases cannot be carried
towards the personnel, air intakes servicing personnel areas or to-
wards the compressor’s air intake.
E. Motor fuel, oils, coolants, lubricants and electrolyte use are typical of
the industry. Ensure that no accidental ingestion or contact with the
skin occurs. If ingestion occurs, make sure that the correct medical
treatment is given immediately. If fuel is ingested do not provoke vom-
iting. If there is skin contact wash with soap and water and, if neces-
sary contact a doctor immediately.
F. When servicing a battery, always wear an acid resistant apron and a
face shield or goggles. If acid spills on skin or clothing, immediately
flush with large volumes of water.
G. Wear protective goggles or a complete face shield, when inspecting
either starting aid systems or when adding antifreeze to the air line an-
tifreeze systems. At start up, keep valve openings, tube or atomizers
of the ether starting aid system pointed away from yourself or other
personnel.
H. If air line anti-icer system antifreeze compound enters the eyes or if
fumes irritate the eyes, they should be washed with large quantities of
clean water. A physician, preferably an eye specialist, should be con-
tacted immediately.
I. Do not store ether or antifreeze for the air line anti ice systems in the
operators’ cabs or in an enclosed area.
J. The antifreeze compound used in air line anti-icer systems contains
methanol and is toxic, harmful or fatal if swallowed. Avoid contact with
the skin or eyes and avoid breathing the fumes. If swallowed, have pa-
tient lay down and cover eyes to exclude light. Call a physician imme-
diately.
1.8 ELECTRICAL SHOCK
A. Ensure that the towing vehicle or equipment carrier compressor, hos-
es, tools and all personnel are kept at a distance of at least 3 meters
from the power lines and buried cables.
B. Keep all parts of the body and any hand tools or any other conductive
objects away from exposed live parts of the electrical system. When
carrying out adjustments or repairs keep feet dry, stand on insulating
surfaces and make sure that no parts of the compressor come in con-
tact with exposed live parts of the electric system.
C. Attempt repairs only in clean, dry well lighted and ventilated areas.
D. Stay clear of the compressor during electrical storms. It can attract
lightning.
1.9 LIFTING
A. If the compressor is provided with a lifting bail, then lift by the bail pro-
vided. If no bail is provided, then lift by sling. Compressors to be air
lifted by helicopter must not be supported by the lifting bail, but by
slings instead. In any event, lift only in full compliance with European
Transport Regulation.
B. Inspect lifting bail and points of attachment for cracked welds and for
cracked, bent, corroded or otherwise degraded members and for
loose screws or nuts proir to lifting.
C. Make sure that the entire lifting, rigging and support structure has
been inspected: check that it is in good condition and its rated capacity
is at least equal to the net weight of the compressor plus an additional
10% allowance for the weight of snow, ice, mud or transported tools
and equipment. If you are unsure of the weight, weigh the compressor
before lifting.
D. Make sure lifting hood has a functional safety latch or equivalent, and
is fully engaged and latched on the bail.
E. Use guide ropes or equivalent to prevent twisting or swinging of the
compressor once it has been lifted clear of the ground.
F. Do not attempt to lift in high winds.
G. Keep personnel out from under, and away from, the compressor when
it is suspended.
H. Lift compressor no higher than necessary.
I. Keep lift operator in constant attendance whenever compressor is
suspended.
J. Set down the compressor on a level surface capable of supporting at
least its own weight plus additional 10% allowance for snow, ice, mud
or equipment and tools carried.
K. If the compressor has parking brakes, make sure they are set. In any
event, block or chock the two sides of all running wheels prior to dis-
engaging the lifting hook.
L. The hoisting eyebolt does not use like a fasteneing device for air stor-
age.
1.10 ACCIDENTAL ENTRAPMENT
A. Make sure all personnel are out of the compressor before closing and
latching the access doors. If the compressor is large enough to hold a
man, and if it is necessary to enter it to carry out maintenance or ad-
justment, inform other personnel before doing so.
1.11 JUMP STARTING
A. Observe all safety precautions mentioned elsewhere in this manual.
B. The batteries might produce hydrogen gas, which is inflammable and
explosive. Keep flames, sparks and other ignition, sources away.
C. The batteries contain acid which is corrosive. take care that it does not
come in contact with eyes, skin, fabrics or painted surfaces since se-
rious personnel injury or property damage could occur. Flush any con-
tacted areas thoroughly with water immediately. When carrying out a
jump start, always wear an acid resistant apron and a face shield.
D. Remove all vent caps from the battery or compressor batteries. Stop
any dirt or other foreign bodies entering the open cells.
E. Check electrolyte level. If it is too low, top up to correct level prior to
attempting a jump start.
F. Only attempt to jump start with a vehicle having the same electrical
voltage system with a negative grounding, and which is equipped with
a battery or batteries of comparable size or larger than that of the com-
pressor battery. Do not attempt a jump start using motor generating
sets, welders or other DC power sources,as serious damagecould re-
sult.
G. Only use jump cables which are clean, in good condition and heavy
enough to handle the starting current.
H. Avoid any accidental contact with the jump cable terminal clips or
clamps and any metallic part of either the compressor or the starting
vehicle, to minimize the risk of uncontrolled arcing which could act as
an ignition source.
I. The positive battery terminals are usually identified by a plus (+) sign
on the terminal, and by the initials POS adjacent to it. The negative
battery terminals are usually identified by a minus (-) sign on the ter-
minal and by the initials NEG adjacent to it.
J. Start the compressor in accordance with normal procedure. Avoid a
prolonged start-up phase.
K. Warm up the compressor. When warm and operating smoothly at nor-
mal idle rmp, disconnect the jumper cable from the engine block on
the compressor, and then disconnect the other end of this same cable
from the negative grounded terminal (NEG) (-) of the starting vehicle’s
battery. then disconnect the other jumper cable from the positive
(POS) (+) terminal of the compressor battery. Remove and carefully
dispose of the dampened cloths. Because they might be contaminat-
ed with battery acid. Replace the vent caps.

3. DESCRIPTION
3.1 WORKING PRINCIPLE
ROTARY SCREW COMPRESSOR
3.2 DESCRIPTION OF COMPONENTS
The package includes a compressor unit, diesel engine, compressor inlet
system, compressor cooling and lubrication system, compressor dis-
charge system, capacity control system, a fuel tank, instrument panel and
electrical system. The compressor is also supplied with sound insulation
to lower noise emissions to a legally acceptable level.
The rigid tiltable canopy gives complete access to all components.
The airend compressor unit is driven by an industrial engine designed to
provide enough horsepower for more than adequate reserve at rated con-
ditions. Refer to the Engine Operator’s manual for a more detailed de-
scription of the engine.
The engine cooling system is comprise of a radiator, high capacity fan,
engine fluid cooler and thermostats. The fan draws air through the radia-
tor, keeping the engine at the proper operating temperature.
Another an is used to cool the fluid usedin thecompressorlubricationand
cooling system.
The engine drives the air end compressor via trapezoidal belts. The com-
pressor’s fuel tank has sufficient capacity for a full day’s operation.
3.3 AIR END COMPRESSOR UNIT
FUNCTIONAL DESCRIPTION
The air end compressor unit (1) is a single-stage, positive displacement,
fluid lubricated-type compressor. This unit provides continuous pulse-
free air to meet your needs and it does not require any maintenance of
inspection of its internal parts.
Fluid is unjected into the compressor unit, at each compression cycle and
mixes directly with the air as the screws turn.
The fluid has three main functions:
• As coolant, it controls the rise of air temperature associated with the
heat of compression.
• Seals the leakage paths between the rotors and the stator and also be-
tween the rotors themselves.
• Acts as a lubricating film between the rotors allowing one rotor to direct-
ly drive the other, which is an idler.
After the air/fluid mixture is discharged from the compressor unit, the fluid
is separated from the air. At this time, the air flows to your service line (13)
and the fluid is cooled in preparation for reinjection.
3.4 COMPRESSOR COOLING AND LUBRICATION
SYSTEM
The compressor cooling and lubrication system is designed to provide
adequate lubrication as well as maintain the proper operating tempera-
ture of the compressor.
• The fan (3) draws air through the cooler (4) to remove heat produced by
air compression.
• The fluid filter (2) stops impurities entering the air end compressor unit
(1).
In operation, fluid circulates from the separtor (5) to the cooler (4). This
circulation is caused by the pressure difference between the separator
(high pressure) and the low pressure zone of the air end compressor unit.
It is a radiator type cooler. The fan (3) sucks in air and discharges it
through the cooler, therby removing heat generated due to fluid compres-
sion. The fluid is then returned to main fluid filter (2) where it is filtered pri-
or to being re-injected into the compression chamber and bearings of the
compressor unit where it functions as a lubricant.
3.5 COMPRESSOR DISCHARGE SYSTEM
FUNCTIONAL DESCRIPTION
The air end compressor unit discharges compressed air/fluid mixture into
the separator.
The separator has four functions:
• It primary fluid separation system.
• Serves as the compressor fluid tank.
• Houses the air/fluid separator.
• Air reseve for the régulation.
The compressed air/fluid mixture enters the separator and is directed
against the side wall.
By change of direction and reduction of vellocity, larger droplets of fluid
fall to the bottom of the sump. The fractional percentage of fluid remaining
in the compressed air collects on the surface of the final separator car-
tridge (6) as the compressed air flows through it .
As more and more fluid collects on the cartridge surface the fluid de-
scends to the bottom of the separator. A return circuit (or plunger pipe 7)
links the bottom of the separator cartridge to the air end compressor inlet.
Fluid collecting on the bottom of the separator cartridge is returned to the
compressor by the pressure difference between the area surrounding the
separator cartridge and the compressor inlet. The return line includes an
orifice (14) which ensures proper flow.
The separator is CEE code rated at 1310 kPa (13 bar) working pressure.
A calibrated port (17), located downstream from the separator, helps
maintain a minimum receiver pressure of 350 kPa (3,5 bar) under all con-
ditions. This pressure is necessary for proper air/fluid separation and
proper fluid circulation.
A non return valve (19) is installed at the tap inlet to prevent compressed
air in the sevice line from bleeding back into the receiver on shutdown
when the compressor is being run in parallel with other compressors
linked to a large air system.
A pressure relief valve (9) located on the separator is set to open if the
sump pressure exceeds 900 kPa (9 bar). A temperature switch will shut-
cown the compressor if the discharge temperature reaches the admissi-
ble maximum temperature.

R
ADMISSION
The spacing of the lobes in front of the intake
port (A) creates a partial vacuum, enabling am-
bient air to enter the groove of the rotary
screws.
COMPRESSION
The meshing of the rotary screws traps the in-
take air, which is progressively compressed by
the rotation.
DELIVERY
The compressed air is progres-sively routed to
the exhaust port (R).

3.6 REGULATING SYSTEM
3.6.1 Starting
The pressure in the separator (5) is zero, the engine speed control cylin-
der (9) retains the engine speed control level in the full speed position.
When the ignition is switched on and the starter is activated:
- The safety devices are disconnected during the start-up phase by
means of a relay (see ch. 6).
- The engine starts and drives the compressor.
3.6.2 Operation of compressor set according to air consumption
There are three possible air consumption configurations:
A. High consumption: >= to the compressor delivery.
The pressure in the separator (5) never reaches the maximum pressure
and the compressed air does not active the controller (10) of the REGU-
LAIR unit. The cylinders (16) and (9) are therefore not supplied with air.
The inlet valve (A) fully opens and the engine runs at maximum speed.
B. Average consumption: < to the compressor delivery.
The pressure in the separator (5) reaches the working pressure. The con-
troller (10) of the regulair unit opens and supplies the cylinder (16) which
slightly closes the inlet valve (A), the pressure also pushes on the engine
speed control cylinder piston (9) which reduces the engine speed. The
lower the air consumption, the higher the pressure in the separator (5) is.
The governor (10) continues to supply the cylinder (16 & 9) at a higher
and higher pressure ; this tends to close the inlet valve (A) end reduce the
engine speed which in turn reduces the compressor output.
The positions of cylinders (16 & 9) are stabilized by a slight leak through
the controller (10 & 15).
In this configuration, the compressor rotates at a speed proportional to
the consumption.
C. Zero consumption: outlet valves (11) closed.
The pressure in the separator (5) is maximum. Cylinder (16), supplied at
this maximum pressure by the controller (10), closes the inlet valve (A).
Cylinder (9), which is also supplied, adjusts the engine to run at idling
speed. Only a very small quantity of air is compressed to ensure the lu-
brication system functions correctly. The excess compressed air can es-
cape through the bleeder valve (12) and the nozzle (15).
3.6.3 Shutting down: when the ignition is switched off
The solenoid (ref.18 photo 1) is disconnected and stops the engine.
The compressor stops feeding air. The inlet valve (A) is no longer under
depression and closes immediately due to its return spring and the back
pressure of the separator.
The bleeder valve (12) commanded by the remaining compressor’s pres-
sure connects the separator to the compressor’s air intake.
This action allows for quick re-start if necessary.
The control cylinder (16) is then released and the engine speed control
cylinder (9) places control lever in the full speed position.
3.7 SAFETY DEVICES
• Pressure relief valve (8) on the separator.
3 safety devices are provided to shut down the engine by an electro stop
(e) (see section 6) when a fault occurs.
The battery charge lamp on the instrument panel then lights up.
The safety devices protect the engine and compressor against the risks
of :
• Engine oil pressure drop: Pressure switch (g).
• Compressor overheating: Thermal switch (T2).
• Engine overheating: Water thermal switch (T1).

4. USE
4.1 TRANSPORT (photo 5)
• Adjust the drawbar for the correct height and check the tyre inflation
pressure.
• Connects the light cables into the socket on the front of the chassis
(standard 7 pin socket ref.1) and check the lights.
• For non-braked compressors, attach the safety chains to the two rings
provided on the compressor chassis and to the towing vehicle. These
chains must be kept as short as possible without however affecting the
maneouvring of the towing vehicle.
• For braked compressors, attach the safety cable, integral with the park-
ing brake (ref.2) , to the towing vehicle to ensure automatic braking of
the unit if the coupling breaks.
Release, the parking brake if necessary.
NOTE:
These braked compressor units have an automaticreversingdevice mak-
ing it possible to reverse with the towing vehicle without damaging the
drawbar. This is possible because of an integrated system which stops
the brake shoes blocking.
This system requires a strong action on the parking brake lever to make
sure that the non-coupled unit is blocked. In this case, make sure that the
unit is completely blocked after using the lever.
• Place the front wheel or the drawbar stand to the «towing» position.
Handling with lifting ring (photo 6)
To use the lifting ring (1), open the cover to let the sling pass through the
hole. Lift the unit after making sure that the capacity of the hoisting equip-
ment is sufficient.
After handling, re-close the cover.
4.2 PARKING OR LOCATING COMPRESSOR
The compressor set must always be positioned on a stretch of flat and
level ground.
The maximum permissible transverse and longitudinal gradient is 15°
(see drawing).
If necessary, insert chocks under the wheels.
To conform with the sound level regulations pertaining to Public Works
equipment, the compressor should be operated with the "canopy closed",
the cooling of the compressor set is only ensured when the canopy is
closed.
In a very dusty environment, install the compressor set in the least pollut-
ed area.
The set should be operated in a ventilated place and should never be op-
erated in an enclosed area unless the latter is of sufficient dimensions
and provided with suitable ventilation for the discharge of hot air and ex-
haust gases and the supply of fresh air.
A flexible hose with a minimum diameter of 100 mm is to be provided for
the discharge of the engine exhaust gases. This hose should be insulated
to avoid any risks of fire.
To avoid any risk of recycling hot air, never place the fresh air suction
ports, hot air discharge ports and exhaust outlet too close to an obstacle.
4.3 PREPARING THE BATTERY FOR SERVICE
- Connect the battery terminals without overtightening the nuts.
- Start the engine and allow to run for at least 10 minutes.
To ensure proper operation, it is recommended to give the battery a boost
charge for at least 2 hours at a 1/10 of its capacity and to use the com-
pressor for a long enough period after installation of the new battery.
4.4 PRECAUTIONS TO BE TAKEN PRIOR
TO STARTING
NOTE:
For all engine procedures consult the engine manual.
Contact the SULLAIR specialist prior to starting a compressor set which
has not been used for a long period (more than six months) or has not
been specially prepared for long shut down periods.
CHECK:
• The compressor set internal cleanliness (oil, fuel, cloths, etc…).
• The compressor air filter cleanliness if working in a very dusty atmos-
phere (see clogging indicator ref.1 photo 7). Pinch dust valve drain
(ref.2).
• The engine oil level: Dipstick (ref.1 photo 8).
Check the engine oil level before starting the engine or more than five
minutes after it has been stopped.
Lift out the oil level dipstick, wipe it clean, reinsert it, take it out again, and
check the oil level. (A) engine oil level within this range is proper.
If the oil level is too low, remove the oil filler plug (see ch. 2.2), and supply
new oil to the prescribed level.
Never overfill above the dipstick maximum mark.
• Check the engine coolant in the reserve tank (ref.1 photo 9). If must be
within the range between «full» and «low», and in the event of insuffi-
cient coolant, fill the radiator with special coolant.
Never top up the coolant level with water.

IMPORTANT
• Be sure to tighten the radiator pressure cap (ref.2 photo 9) securely af-
ter filling up.
• The separator oil level: Keep the level at maximum (fig S).
The maxi level is determined by the filling hole thus it cannot be over-
filled.
• The battery electrolyte level: should be from 10 to 15 mm above the
plates. Top-up with distilled water if necessary.
• Fuel pre-filter cleanliness (part 2, photo 14). The filter should not contain
water or dirt. If necessary change it.
To ensure that the oil levels are stabilized, they should always be
checked when the compressor set is cold.
Use only the oils recommended in the maintenance section.
4.5 FILLING FUEL TANK
- Correctly close the filler cap (ref.1 photo 10) after refueling.
- Clean all overflow diesel fuel.
- Do not smoke.
- Use a strainer when filling the fuel tank, or dirt or sand in the fuel
may cause trouble in the fuel injection pump.
- Keep the engine away from fire when filling.
Ensure that only clean diesel fuel conforming to engine constructor spec-
ifications (below), is used - especialy in cold weather:
• DIN 51-601.
• ASTM D 975-81: 1-D and 2-D
• Codes OTAN F 54, F 75 and F 76
• VV-F-800a: DF-A, DF-1 and DF-2
• BS 2869: A1 and A2
(For A2 comply with sulphur content)
• Do not draw fuel from a drum if it has not been decanted. Never use the
fuel remaining at the bottom of a drum.
• Fill the fuel tank in the evening to avoid water condensate formation
during the night.

4.7 STARTING (photo 12)
Starting should not be attempted until all the operations detailed in the
previous section have been accomplished.
IMPORTANT
In very cold weather respect imperatively the engine maker’s instructions.
1. Open the air outlet valves: No load Start.
Turn on the COM selector switch (5) : the battery charge lamp (3)
lights up.
2. Position 2 on COM (5) : Preheating. Hold down until PRE lamp (4)
goes out.
3. Turn to position 3 to engage the starter then release as soon as the
engine starts.
NOTE:
The start-up position also feeds the preheating spark plugs.
4. Do not try for more than 10 seconds in very cold weather. Recom-
mence step 2.
5. Allow the compressor set to warm up for about 5 minutes and pro-
gressively close the outlet valve, to obtain a stabilized pressure
between 6 and 7 bars. The compressor runs at regulating system.
4.8 UTILIZATION
Connect the supply hoses to the valves (not connected) and progressi-
vely open the valves to purge them. Never open the valves abruptly, to
avoid dirt projection and hose whiplashing which could cause an acci-
dent.
Then shut the valves before connecting the tools and reopen them pro-
gressively to use the tools.
NOTE:
Do not forget to apply the manufacturer’s instructions for pneumatic tools
before connecting to the compressor.
4.9 SHUTTING DOWN
- Close the air valves and let the compressor set idle for 1 ou 2 minu-
tes to avoid a sudden stop, especially after intensive use in cold
weather.
- Switch off the ignition switch (5).
NOTE:
In case of long shut down (more than 6 months) contact your SULLAIR
specialist to insure the “Long Period” shut down treatment to avoid star-
ting difficulties later.

5. MAINTENANCE
IMPORTANT
The maintenanceoperations indicated in thismanual are given for normal
conditions. In difficult conditions, extreme temperatures, high relative hu-
midity, polluted or dusty environment, high altitude etc… certain opera-
tions must be carried out more frequently and certain precautions must
be taken. Consult the engine maker’s manual and your local SULLAIR
specialist.
Also respect elementary safety rules to avoid accidents (See ch.1).
Waste disposal:
Drained ingredients like oil, fuel, grease, cooling fluid, battery acid and
detergents should not penetrate the soil. They should be collected in suit-
able containers and be disposed according to environment-friendly pre-
scriptions. This applies to all filter cartridges and spare parts as well.
WARNING!
DO NOT remove caps, plugs, or other components
when compressor is running or pressurized. Stop com-
pressor and relieve all internal pressure before doing
so.
RUNNING IN
The compressor set must be closely monitored during the running in pe-
riod. Besides the daily operations (or 10 hourly operations), the following
specific operations must be done after 50 hours:
5.1 MAINTENANCE - First 50 hours
5.2 MAINTENANCE 10 HOURS (or daily)
- Check the engine coolant level:
The engine coolant level with reserve tank must be within the range
between «full» and «low» (see ch.4.5).
- Check the engine oil level:

- Engine oil pressure drop: pressure switch (g).
- Abnormal engine coolant temperature rise: temperature switch
(T1).
- Abnormal oil/air temperature rise at the compressor unit’s dischar-
ge: temperature switch (T2).
They function by closing their contacts at earth which energize the safety
relay (RS). The latter opens its contact and cuts off the electro-stop (ES)
which in turn cuts the engine injection (even with a passing fault).
The engine stops. The air circuit is decompressed. The load indicator li-
ght lights up. The hour meter stops counting.
