SAFETY PRECAUTIONS
Before using your compressor it is in your own interest to read and pay
attention to the following safety precautions.
1. Compressed air is dangerous. DO NOT point a jet of air at persons or animals, and do
not discharge compressed air against the skin.
2. DO NOT operate your compressor with the guard removed.
3. Repairs must only be carried out by a qualified engineer. If problems occur, contact
your CLARKE dealer.
4. Before carrying out any maintenance make sure that the pressure is released from
the air reservoir and that the compressor is disconnected from the electrical supply.
5. DO NOT leave pressure in the receiver overnight or when transporting.
6. DO NOT adjust or tamper with the safety valves. The maximum pressure is factory set,
and clearly marked on the compressor.
7. DO NOT operate in wet or damp conditions. Keep the compressor dry at all times.
Similarly, clean air will allow the compressor to work efficiently. DO NOT use in dusty
or otherwise dirty locations.
8. Some of the metal parts can become quite hot during operation. DO NOT touch/
remove these until the compressor has cooled down.
9. ALWAYS set any pressure regulator to the recommended setting for the tool.
10. When spraying flammable materials e.g. cellulose paint, ensure that there
is sufficient airflow and keep clear of any source of ignition.
11. Before spraying any material always consult paint manufacturers instructions for
safety and usage.
12. Protect yourself. Goggles will protect your eyes from flying particles. Face masks will
protect you against paint spray and fumes.
13. DO NOT apply strain to electrical cables and make sure that air hoses are not kinked
or wrapped around the compressor.
14. When disconnecting air hoses or other equipment from your compressor, make sure
that the air supply is turned off at the outlet and vent all pressurised air from within
the reservoir and other equipment attached to it.
15. Make sure that children and animals are kept well away from the compressor and
any equipment attached to it.
16. Make sure that all individuals using the compressor have had any necessary training
and have read and fully understand these operating instructions.
17. Make sure that any equipment or tool used in conjunction with your compressor, has
a safe working pressure exceeding that of the compressor.
18. Be careful when transporting the compressor to prevent tipping over.
19. Permanently installed systems must be installed by a competent engineer.
20. These compressors produce noise levels in excess of 70dB(A). Persons working near
the compressor must be supplied with ear protection.

automatically in the event of a power cut and subsequent
reset. DO NOT move the compressor while it is connected
to the power source, or when the tank is filled with
compressed air.
This compressor contains surfaces which may reach a high
temperature during operation. NEVER operate with the

INSTALLATION
Before installing your machine, check that its air output is sufficient for the
equipment to be used. The air output from the compressor must be more than
the volume of air required. We recommend the following:
1. 1. Firm and level site, and the use of floor mountings for stationary
compressors - anti-vibration pads. (Do not bolt machines directly to the
floor).
2. Dust and damp free environment.
3. Adequate ventilation for:-
• Air intake to compressor pump (in order to draw in clean air).
• Cooling to compressor pump, and electric motor.
4. To allow sufficient access for servicing, a minimum clearance of 500mm
must be allowed around the machine.
5. The power cable from the main supply must be large enough to carry the
starting and running load of the electric motor. This is particularly relevant if
the compressor is some distance from the source of supply.
6. Electrical installations should be completed by a qualified electrician.
ELECTRICAL CONNECTIONS
Connect the three core mains cable to a suitable industrial supply isolator, or
heavy duty plug meeting the requirements of BS EN 60309. This compressor
must be connected to a supply having a rated capacity of greater than 16
Amps.
A normal 13 Amp (BS1363) plug must NOT be used.
WARNING: THIS APPLIANCE MUST BE EARTHED.
IMPORTANT: The wires in this mains lead are coloured in accordance with the
following code:
GREEN AND YELLOW - EARTH (E)
BLUE - NEUTRAL (N)
BROWN - LIVE (L)
WARNING: READ THESE ELECTRICAL SAFETY INSTRUCTIONS
THOROUGHLY BEFORE CONNECTING THE PRODUCT TO THE MAINS
SUPPLY.

As the colours of the flexible cord of this appliance may not correspond with
the coloured markings identifying terminals, proceed as follows:
• Connect GREEN AND YELLOW coloured cable to terminal marked
“E” or Earth Symbol or coloured Green and Yellow.
• Connect BROWN cable to terminal marked ‘L’ or coloured Red.
Connect BLUE cable to terminal marked “N’ or coloured Black.
BEFORE USE
Before connecting your compressor to the power supply, check the following:
• Set the ON/OFF switch to the
OFF position (pushed down).
• Make sure that the compressor
is on level ground.
• Make sure that the supply
voltage matches the voltage
shown on the data label.
CHECK THE OIL LEVEL
1. .Ensure the oil level is filled up to
the mark on the sightglass.
2. If low, top up after unscrewing the
filler plug.
• Only use ISO100 (SAE30)
compressor oil, available from
your Machine Mart dealer Part
No. 3050796.
• Take care not to overfill.
CAUTION: TO PREVENT INJURY, GET ASSISTANCE WHEN LIFTING OR
MOVING THIS COMPRESSOR.

OPERATION
If the compressor has not been used for more then 24 hours, open the drain
valve (on the bottom of the reservoir) and drain any condensate which has
collected. See page 10.
MOVING THE AIR COMPRESSOR
• Stop the compressor and disconnect it from the power supply
before you move it.
•DO NOT lift by (or put strain on) valves or hoses.
• Avoid moving the machine if the tank is fully pressurised.
ATTACHING AIR TOOLS
1. Attach the air hose to the outlet
valves.
2. Attach the air tool to the other
end of the air hose.
3. Turn the outlet valve handle to the
on position.
NOTE: The outlet valve is shown
without the air hose fitted for
clarity.
NOTE: To adjust the output pressure
we recommend that a
pressure regulator (not
supplied) be fitted between
the compressor and the tool.
WARNING: BEFORE CONNECTING AIR TOOLS, MAKE SURE THAT YOU
READ THE INSTRUCTIONS SUPPLIED WITH THE TOOL, ALSO ENSURE THAT
THE TOOL IS SUITABLE FOR USE WITH THE COMPRESSOR AND HOSE
SPECIFICATIONS.

TURNING THE COMPRESSOR ON
1. Plug the compressor into the power supply.
2. Lift the On/Off button.
• The compressor will operate
until the reservoir is fully
pressurised. It will then shut
down.
• The compressor will start up
again when the pressure in the
reservoir decreases.
CHECKING THE SAFETY VALVE
To make sure that the safety valve works correctly;
1. Unscrew and pull the knurled part
of the safety valve.
• Air will be released when you
pull hard on the valve end and
stop when released.
2. If the valve does not operate in
this way, do not use the
compressor. The compressor must
be repaired by a qualified service
agent.
3. Once tested, screw the knurled part back.
WARNING: DO NOT REMOVE OR TRY TO ADJUST THE SAFETY VALVE.

off position.
3. Operate the tool to depressurise
the air hose.
4. Disconnect the tool from the hose.
TURNING THE COMPRESSOR OFF
1. Follow steps 1-3 in “Removing Tools from the Air Hose” above.
2. Disconnect the compressor from the power supply.
3. Slowly open the outlet valve to depressurise the reservoir.

DRAINING THE RESERVOIR
1. Turn the compressor off and
disconnect from the power
supply.
2. Put a container below the drain
valve to collect the condensate.
3. Open the drain valve slowly.
• Condensation will drain from
the reservoir.
4. Close the drain valve when the
reservoir has fully drained.
USING THE RESET BUTTON
This compressor has a thermal
overload device.
If the motor gets too hot, the thermal
overload device cuts the power
which prevents damage to the motor.
If the thermal overload device
operates, let the motor cool down for
5 minutes and push the reset button.
If you start the compressor and the
overload cutout operates again, stop
the compressor and disconnect from the power supply and have your
compressor examined by a qualified service agent.
CAUTION: YOU MUST DRAIN THE RESERVOIR AFTER EACH DAYS USE AND
BEFORE YOU PUT YOUR COMPRESSOR INTO STORAGE.
