ASSEMBLING THE COMPRESSOR
NOTE: The information contained in this Instruc-
tion Manual is designed to assist you in the safe
operation and maintenance of the compressor.
Some illustrations in this Instruction Manual
may show details or attachments that differ
from those on your own compressor.
1. Remove the compressor from its packing
(Fig.1). Make sure it is in perfect condition,
check if it was damaged during transport,
and carry out the following operations.
2. Fit the wheels and rubber tab on the tanks
on which they are not already fitted, observ-
ing the instructions (Fig.2). In case of inflat-
able wheels, the maximum inflation pres-
sure must be of 1.6 bar (24psi).
3. Position the compressor on a flat surface or
with a maximum permissible inclination of
10o(Fig. 3), in a well aired place, protected
against atmospheric agents and not in a
place subject to explosion hazard.
If the surface is inclined and smooth, check
if the compressor moves while in opera-
tion - if it does, secure the wheels with two
wedges.
4. To ensure good ventilation and efficient
cooling, the compressor’s belt guard must
be at least 1 metre from any wall (Fig. 4).
Compressors fitted on the tank, with fixed
feet, should not be rigidly secured to the
ground. In this case, we advise you to fit 4
anti-vibration supports.
5. Take care to transport the compressor cor-
rectly, do not overturn it or lift it with hooks
or ropes (Fig. 5)
6. Replace the plastic plug on the guard cover
(Fig. 7-8) with the oil level stick (Fig. 9) or
with the relevant breather plug (Fig. 10),
supplied with the instructions booklet.

9.
7. Check oil level, con-
sulting the refer-
ence marks on the
stick (Fig. 9) or the
oil level inspection
window (Fig. 11).
QUICK START GUIDE
1. Add Engine Oil:
- Ensure engine is kept perfectly upright / level.
- Fill until oil runs back out of filler hole
DO NOT OVERFILL
DO NOT TILT WHILE FILLING
OIL TYPES: 10W30 / 10W40 / 15W30 / 15W40
2. Compressor Oil Level:
- Check that compressor unit oil level is correct
OIL TYPE: HYDRAULIC ISO VG 100
3. Connect Battery (if equipped):
- Connect red to red (+)
- Connect black to black (-)
NEVER REVERSE BATTERY CONNECTIONS OR
PERMANENT NON-WARRANTABLE DAMAGE
WILL OCCUR.
4. Add Fuel:
- Use only clean, fresh commercially available
fuel.
5. De-pressurise Air Tank:
- Tank pressure must be low to allow starting
- If starting with any pressure in air tank, activate
manual over-ride toggle on the unloader valve
first.
6. Turn the Fuel Valve to “ON”
7. Switch the Engine Switch to “ON”
8. Set the Choke:
COLD ENGINE - Move the choke lever to left
WARM ENGINE - Move the choke lever to right.

10.
MAINTENANCE
Before attempting any maintenance jobs on the
compressor, make sure there is no pressure on
the air tank:
Every 50 Hrs of Duty:
We advise you to dismantle the suction filter
and clean the filtering element by blowing com-
pressed air on it (Fig. 12).
You are recommended to replace the filter ele-
ment at least once if the compressor operates in
a clean environment, but more frequently if in a
dusty environment.
The compressor generates condensate water
which accumulates in the tank. The conden-
sate in the tank must be drained at least once
a week, by opening the drain tap (Fig. 13) un-
der the tank. When draining, take care if there
is compressed air inside the cylinder as water
could flow out with considerable force.
Recommended Pressure:
1 - 2 bar. Condensate of compressors that
are oil lubricated must not be drained into the
sewer or dispersed in the environment as it
contains oil.
12
9. Start the Engine:
KEY START (If equipped) - Turn the ignition key
“ON”. If the battery has enough charge, use the
ignition key to start the engine by holding the
key in the “START” position for a few seconds
(new batteries have little or no charge. Use pull
start, jump start or charge battery if needed).
PULL START - Pull cord repeatedly until the en-
gine starts.
9. More the choke lever to the right
IF ENGINE WILL NOT START:
- Repeat the process above but place and leave
the choke lever to the right.
- Check oil level
- Charge battery or jump start
- Repeat process above
- Ensure there is no air pressure left in the tank

11.
OIL CHANGES & TOPPING UP
We recommend a full change of oil in the pump
within the first 100 hours of duty.
OIL TYPE: HYDRAULIC ISO VG 100 Grade
or equivalent
1. To change the oil, unscrew the oil drain plug
on the housing cover.
2. Allow all the oil to flow out, and re-screw the
plug (Fig. 14 - 15).
3. Pour oil into the upper hole of the housing
cover (Fig. 16 - 17) until it reaches the level
indicated on the stick (Fig. 9) or indicator
(Fig. 11) Pour oil into the upper hole of the
head (Fig. 17) in belt assisted units designed
for topping up in that area.
Once a Week:
Check oil level of the pumping element (fig. 11)
and see if it needs topping up.

TROUBLESHOOTING
Loss of air in unloader valve.
This trouble depends on poor tightness of the
check valve – take the following action (Fig. 18):
1. Discharge all pressure from the tank
2. Unscrew the hexagon-head of the valve (A)
3. Carefully clean both the rubber disk (B) and
its seat.
4. Refit all parts accurately.
Air losses
These can be caused by poor tightness of a un-
ion – check all unions, wetting them with soapy
water.
Compressor turns but does not load
Coaxial compressors: (Fig. 19)
This may be due to failure of the valves (C1 –
C2) or of a seal (B1 –B2). Replace the damaged
part.
Pulley drive compressors: (Fig. 20)
This may be due to failure of the valves F1 and
F2 or of D2). Check if there is too much conden-
sate water inside the tank or replace the dam-
aged part.

21 22 23 24
IMPORTANT:
• Do not on any account unscrew any con-
nection while the tank is pressurized - al-
ways check if the tank is pressure free.
• Do not drill holes, weld or purposely deform
the compressed air tank.
• Do not do any jobs on the compressor un-
less you have disconnected the power plug.
• Temperature in operating ambient: 0oC
+35oC.
• Do not aim jets of water or inflammable liq-
uids on the compressor.
• Do not place inflammable objects near the
compressor.
• During down-times, turn the pressure
switch to position “0” (OFF).
• Never aim the air jet at people or animals
(Fig. 21)
• Do not transport the compressor while the
tank is pressed. Be careful with regard to
some parts of the compressor such as the
head and delivery tubes, as they can reach
high temperatures. Do not touch these
parts to avoid burns.

13.
• Transport the compressor, lifting or pulling
it with the appropriate handles (Fig. 4 - 6)
• Keep children and animals well away from
the machine operating area.
• If using the compressor for painting:
a) Do not work in closed environments or
near to naked flames
b) Make sure there is adequate exchange of
air at the place of work
c) Protect your nose and mouth with an ap-
propriate mask. (Fig. 22)
• If the electrical cable or plug is damaged, do
not use the compressor and contact an au-
thorised service centre to replace the faulty
element with an original spare part.
• If the compressor is located on a shelf or on
a top above floor height, it must be secured
to revent it falling while in operation.
• Do not put objects or your hands inside the
protective grilles to avoid injury to yourself
or damaging he compressor. (Fig. 23)
• Do not use the compressor as a blunt object
toward things or animals, to avoid serious
damage.
• When you have finished using the compres-
sor, always remove the plug from the power
socket.
Acoustic pressure measured free-eld at a dis-
tance of 1m: 80dB(A) at maximum operating
pressure.
HINTS FOR EFFICIENT OPERATION
For efficient operation of the machine at full
continuing load and at maximum operating
pressure, make sure the temperature of the
work environment does not exceed +25oC. We
advise you to use the compressor at 70% maxi-
mum duty per hour at full load as this ensures
efficient operation of the product long-term.
STORING THE COMPRESSOR
For the whole time that the compressor is not
used before unpacking it, store it in a dry place
at a temperature between +5oC and + 45oC and
sheltered away from weather.
For the whole time that the compressor is not
used after unpacking it, while waiting to start
it up or due to production stoppages, place
sheets over it to protect it from dust, which
may settle on the components. The oil is to be
replaced and the operational efficiency of the
compressor is to be checked if it is not used for
long periods.
PNEUMATIC CONNECTIONS
Make sure you always use pneumatic hoses for
compressed air with maximum pressure char-
acteristics that are adequate for the compres-
sor. Do not attempt to repair tubes if faulty.
