SAFETY 7
7/205, 10/175, 12/155, 14/145, 12/205
General Information
Never operate unit without first observing all safety warnings and
carefully reading the operation and maintenance manual shipped from
the factory with this machine.
Ensure that the operator reads and understands the decals and
consults the manuals before maintenance or operation.
Ensure that the Operation & Maintenance manual, and the manual
holder, are not removed permanently from the machine.
Ensure that maintenance personnel are adequately trained, competent
and have read the Maintenance Manuals.
Ensure that ice and snow do not block the cooling air inlets.
Use hearing protectors when unit is running.
Make sure that all protective covers are in place and that the canopy/
doors are closed during operation.
The specification of this machine is such that the machine is not
suitable for use in flammable gas risk areas. If such an application is
required then all local regulations, codes of practice and site rules must
be observed. To ensure that the machine can operate in a safe and
reliable manner, additional equipment such as gas detection, exhaust
spark arresters, and intake (shut-off) valves may be required,
dependant on local regulations or the degree of risk involved.
A weekly visual check must be made on all fasteners/fixing screws
securing mechanical parts. In particular, safety-related parts such as
coupling hitch, drawbar components, road-wheels, and lifting bail
should be checked for total security.
All components which are loose, damaged or unserviceable, must be
rectified without delay.
Air discharged from this machine may contain carbon monoxide or
other contaminants which will cause serious injury or death. Do not
breathe this air.
This machine produces loud noise with the doors open or service valve
vented. Extended exposure to loud noise can cause hearing loss.
Always wear hearing protection when doors are open or service valve
is vented.
Never inspect or service unit without first disconnecting battery
cable(s) to prevent accidental starting.
Do not use petroleum products (solvents or fuels) under high pressure
as this can penetrate the skin and result in serious illness. wear eye
protection while cleaning unit with compressed air to prevent debris
from injuring eye(s).
Rotating fan blade can cause serious injury. Do not operate without
guard in place.
The machine must not be used for transport or storage of explosive,
flammable or other dangerous substances.
Use care to avoid contacting hot surfaces (engine exhaust manifold
and piping, air receiver and air discharge piping, etc.).
Ether is an extremely volatile, highly inflammable gas. When it is
specified as a starting aid, use sparingly. DO NOT USE ETHER IF THE
MACHINE HAS GLOW PLUGS OR INLET HEATER STARTING AIDS
OR ENGINE DAMAGE WILL RESULT.
Never operate unit with guards, covers or screens removed. Keep
hands, hair, clothing, tools, blow gun tips, etc. well away from moving
parts.
Compressed air
Compressed air can be dangerous if incorrectly handled. Before doing
any work on the unit, ensure that all pressure is vented from the system
and that the machine cannot be started accidentally.
Ensure that the machine is operating at the rated pressure and that the
rated pressure is known to all relevant personnel.
All air pressure equipment installed in or connected to the machine
must have safe working pressure ratings of at least the machine rated
pressure.
If more than one compressor is connected to one common
downstream plant, effective check valves and isolation valves must be
fitted and controlled by work procedures, so that one machine cannot
accidentally be pressurised / over pressurised by another.
Compressed air must not be used for a direct feed to any form of
breathing apparatus or mask.
High Pressure Air can cause serious injury or death. Relieve pressure
before removing filler plugs/caps, fittings or covers.
Air pressure can remain trapped in air supply line which can result in
serious injury or death. Always carefully vent air supply line at tool or
vent valve before performing any service.
The discharged air contains a very small percentage of compressor
lubricating oil and care should be taken to ensure that downstream
equipment is compatible.
If the discharged air is to be ultimately released into a confined space,
adequate ventilation must be provided.
When using compressed air always use appropriate personal
protective equipment.
All pressure containing parts, especially flexible hoses and their
couplings, must be regularly inspected, be free from defects and be
replaced according to the Manual instructions.
Avoid bodily contact with compressed air.
The safety valve located in the separator tank must be checked
periodically for correct operation.
Whenever the machine is stopped, air will flow back into the
compressor system from devices or systems downstream of the
machine unless the service valve is closed. Install a check valve at the
machine service valve to prevent reverse flow in the event of an
unexpected shutdown when the service valve is open.
Disconnected air hoses whip and can cause serious injury or death.
Always attach a safety flow restrictor to each hose at the source of
supply or branch line in accordance with OSHA Regulation 29CFR
Section 1926.302(b).
Never allow the unit to sit stopped with pressure in the receiver-
separator system.
Materials
The following substances may be produced during the operation of this
machine:

gases is maintained at all times.
WARNINGS
Warnings call attention to instructions which must be followed
precisely to avoid injury or death.
CAUTIONS
Cautions call attention to instructions which must be followed
precisely to avoid damaging the product, process or its surroundings.
NOTES
Notes are used for supplementary information.

8SAFETY
7/205, 10/175, 12/155, 14/145, 12/205
The following substances are used in the manufacture of this machine
and may be hazardous to health if used incorrectly:
• anti-freeze
• compressor lubricant
• engine lubricant
• preservative grease
• rust preventative
• diesel fuel
• battery electrolyte
AVOID INGESTION, SKIN CONTACT AND INHALATION OF
FUMES.
Should compressor lubricant come into contact with the eyes, then
irrigate with water for at least 5 minutes.
Should compressor lubricant come into contact with the skin, then
wash off immediately.
Consult a doctor if large amounts of compressor lubricant are ingested.
Consult a doctor if compressor lubricant is inhaled.
Never give fluids or induce vomiting if the patient is unconscious or
having convulsions.
Safety data sheets for compressor and engine lubricants should be
obtained from the lubricant supplier.
Battery
Batteries contain corrosive liquid and produce explosive gas. Do not
expose to naked lights. Always wear personal protective clothing when
handling. When starting the machine from a slave battery ensure that
the correct polarity is observed and that connections are secure.
A battery contains sulphuric acid and can give off gases which are
corrosive and potentially explosive. Avoid contact with skin, eyes and
clothing. In case of contact, flush area immediately with water.
DO NOT ATTEMPT TO SLAVE START A FROZEN BATTERY
SINCE THIS MAY CAUSE IT TO EXPLODE.
Exercise extreme caution when using booster battery. To jump battery,
connect ends of one booster cable to the positive (+) terminal of each
battery. Connect one end of other cable to the negative (-) terminal of
the booster battery and other end to a ground connection away from
dead battery (to avoid a spark occurring near any explosive gases that
may be present). After starting unit, always disconnect cables in
reverse order.
Radiator
Hot engine coolant and steam can cause injury. Ensure that the
radiator filler cap is removed with due care and attention.
Do not remove the pressure cap from a HOT radiator. Allow radiator to
cool down before removing pressure cap.
Transport
When loading or transporting machines ensure that the specified lifting
and tie down points are used and cables or chains are in safe limits.
When loading or transporting machines ensure that the towing vehicle,
its size, weight, towing hitch and electrical supply are all suitable to
provide safe and stable towing at speeds either, up to the legal
maximum for the country in which it is being towed or, as specified for
the machine model if lower than the legal maximum.
Ensure that the maximum trailer weight does not exceed the maximum
gross weight of the machine (by limiting the equipment load), limited by
the capacity of the running gear.
When using the handbrake lever ensure there is enough space for it to
operate safely.
Before towing the machine, ensure that:
• the tyres and towing hitch are in a serviceable condition.
• the canopy is secure.
• all ancillary equipment is stored in a safe and secure manner.
• the brakes and lights are functioning correctly and meet necessary
road traffic requirements.
• break-away cables/safety chains are connected to the towing
vehicle.
The machine must be towed in a level attitude (the maximum
permissible drawbar angle is between 0° and +5° from horizontal) in
order to maintain correct handling, braking and lighting functions. This
can be achieved by correct selection and adjustment of the vehicle
towing hitch and, on variable height running gear, adjustment of the
drawbar.
The machine must not be towed on public roads if it is fitted with the
hose carrier option.
To ensure full braking efficiency, the front (towing eye) section must
always be set level.
When adjusting variable height running gear:
• Ensure front (towing eye) section is set level.
• When raising towing eye, set rear joint first, then front joint.
• When lowering towing eye, set front joint first, then rear joint.
• After setting, fully tighten each joint by hand and then tighten further
to the next pin. Refit the pin.
• When parking always use the handbrake and, if necessary, suitable
wheel chocks.
• Make sure wheels, tyres and tow bar connectors are in safe
operating condition and tow bar is properly connected before
towing.
Safety chains / connections and adjustment
The legal requirements for the joint operation of the breakaway cable
and safety chains are as yet unidentified by 71/320/EEC or UK
regulations. Consequently we offer the following advice / instructions.
Where brakes only are fitted:
• Ensure that the breakaway cable is securely coupled to the
handbrake lever and also to a substantial point on the towing
vehicle.
• Ensure that the effective cable length is as short as possible, whilst
still allowing enough slackness for the trailer to articulate without the
handbrake being applied.
Where brakes and safety chains are fitted:
• Loop the chains onto the towing vehicle using the towing vehicle
hitch as an anchorage point, or any other point of similar strength.
• Ensure that the effective chain length is as short as possible whilst
still allowing normal articulation of the trailer and effective operation
of the breakaway cable.
Where safety chains only are fitted:
• Loop the chains onto the towing vehicle using the towing vehicle
hitch as an anchorage point, or any other point of similar strength.
• When adjusting the safety chains there should be sufficient free
length in the chains to allow normal articulation, whilst also being
short enough to prevent the towbar from touching the ground in the
event of an accidental separation of the towing vehicle from the
trailer.
NOTE:
Gross mass (on data plate) is for the basic machine and fuel
only, excluding any fitted options, tools, equipment and foreign
materials.

14 OPERATING INSTRUCTIONS
7/205, 10/175, 12/155, 14/145, 12/205
COMMISSIONING
Upon receipt of the unit, and prior to putting it into service, it is
important to adhere strictly to the instructions given below in PRIOR
TO STARTING.
Ensure that the operator reads and understands the decals and
consults the manuals before maintenance or operation.
Ensure that the position of the emergency stop device is known and
recognised by its markings. Ensure that it is functioning correctly and
that the method of operation is known.
Running gear drawbar (European Area) - Machines are shipped to
some areas with the drawbar removed. Fitting involves four nuts / bolts
to secure the drawbar to the axle and two bolts to fit the drawbar to the
front of the machine with the saddle and spacer block.
Support the front of the machine, fit the wheel chocks to stop the
machine moving and attach the drawbar. Refer to the torque value
table in the MAINTENANCE section of this manual for the correct
torque values.
Fit the propstand and coupling. Remove the supports and set the
machine level.
Before towing the unit, ensure that the tyre pressures are correct (refer
to the GENERAL INFORMATION section of this manual) and that the
handbrake is functioning correctly (refer to the MAINTENANCE section
of this manual). Before towing the unit during the hours of darkness,
ensure that the lights are functioning correctly (where fitted).
Ensure that all transport and packing materials are discarded.
Ensure that the correct fork lift truck slots or marked lifting / tie down
points are used whenever the machine is lifted or transported.
When selecting the working position of the machine ensure that there
is sufficient clearance for ventilation and exhaust requirements,
observing any specified minimum dimensions (to walls, floors etc.).
Adequate clearance needs to be allowed around and above the
machine to permit safe access for specified maintenance tasks.
Ensure that the machine is positioned securely and on a stable
foundation. Any risk of movement should be removed by suitable
means, especially to avoid strain on any rigid discharge piping.
Attach the battery cables to the battery(s) ensuring that they are
tightened securely. Attach the negative cable before attaching the
positive cable.
CAUTION: This is a safety critical procedure. Double check the
torque settings after assembly.
WARNING: All air pressure equipment installed in or connected
to the machine must have safe working pressure ratings of at
least the machine rated pressure, and materials compatible with
the compressor lubricant (refer to the GENERAL INFORMATION
section).
WARNING: If more than one compressor is connected to one
common downstream plant, effective check valves and isolation
valves must be fitted and controlled by work procedures, so that
one machine cannot accidentally be pressurised / over pressur-
ised by another.
WARNING: If flexible discharge hoses are to carry more than 7
bar pressure then it is recommended that safety retaining wires
are used on the hoses.

OPERATING INSTRUCTIONS 15
7/205, 10/175, 12/155, 14/145, 12/205
PRIOR TO STARTING
1. Place the unit in a position that is as level as possible. The design
of the unit permits a 10 degree lengthways and sideways limit on
out of level operation. It is the engine, not the compressor, that is
the limiting factor.
When the unit has to be operated out of level, it is important to keep the
engine oil level near the high level mark (with the unit level).
2. Check the engine lubrication oil in accordance with the operating
instructions in the Engine Operator’s Manual.
3. Check the compressor oil level in the sight glass located on the
separator tank.
4. Check the diesel fuel level. A good rule is to top up at the end of
each working day. This prevents condensation from occurring in the
tank.
5. Check the DEF level and add fluid as necessary. Use API certified
DEF which meets ISO22241. The DEF pump contains a filter that
should be replaced at regular intervals. (See Maintenance
Schedule.)
6. Drain the fuel filter water separator of water, ensuring that any
released fuel is safely contained.
7. Check the radiator coolant level (with the unit level).
8. Open the service valve(s) to ensure that all pressure is relieved
from the system. Close the service valve(s) when all pressure is
relieved.
10.Check that the emergency stop switch is not engaged. Pull knob to
release if necessary.
11.Close the manual relief valve inside the unit, on the top of the
separator tank.
When starting or operating the machine in temperatures below or
approaching 0°C (32°F), ensure that the operation of the regulation
system, the unloader valve, the safety valve, and the engine are not
impaired by ice or snow, and that all inlet and outlet pipes and ducts
are clear of ice and snow.
CAUTION: Do not overfill either the engine or the compressor with
oil.
CAUTION: When refuelling:-
• switch off the engine.
• do not smoke.
• extinguish all naked lights.
• do not allow the fuel to come into contact with hot surfaces.
• wear personal protective equipment.
9. CAUTION: Do not operate the machine with the canopy/doors in
the open position as this may cause overheating and operators to
be exposed to high noise levels.
