SAFETY PRECAUTIONS

Before using your compressor it is in your own interest to read and pay
attention to the following safety rules.

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 the 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.

WARNING: READ THESE ELECTRICAL SAFETY INSTRUCTIONS
THOROUGHLY BEFORE CONNECTING THE PRODUCT TO THE MAINS
SUPPLY.

Connect the mains lead to a standard, 230 Volt (50Hz) electrical supply
through an approved 13 amp BS 1363 plug, or a suitably fused isolator switch.

If the plug has to be changed because it is not suitable for your socket, or
because of damage, it must be removed and a replacement fitted, following
the wiring instructions shown below. The old plug must be discarded safely, as
insertion into a power socket could cause an electrical hazard.

terminal which is
marked L or coloured
red.

• The YELLOW AND

GREEN wire must be
connected to the terminal which is marked E or or coloured green.

We strongly recommend that this machine is connected to the mains supply
through a Residual Current Device (RCD).

If you are not sure, consult a qualified electrician. DO NOT try to do any
repairs.

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 on the knurled
part of the safety valve.

• Air will be released when you

pull hard on the valev 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 in.

WARNING: DO NOT REMOVE OR TRY TO ADJUST THE SAFETY VALVE.

SETTING THE OUTLET PRESSURE

1. Use the pressure regulator to set
the outlet pressure.

• Turn clockwise to increase the

pressure.

• Turn counterclockwise to

decrease the pressure.

From The Air Hose” above.

2. Disconnect the compressor from
the power supply.

3. Slowly open the outlet valve to
depressurise the reservoir.

• You will hear a hissing sound as

the reservoir depressurises.

4. Do not leave the compressor
unattended if the reservoir is pressurised.

DRAINING THE RESERVOIR

CAUTION: YOU MUST DRAIN THE RESERVOIR AFTER EACH DAYS USE AND
BEFORE YOU PUT YOUR COMPRESSOR INTO STORAGE.

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

MAINTENANCE

WARNING: MAKE SURE THAT THE COMPRESSOR IS DISCONNECTED FROM
THE ELECTRICAL SUPPLY BEFORE CARRYING OUT ANY MAINTENANCE

DRAIN THE RESERVOIR

After use, always open the drain valve to make sure that any condensate is
drained off.

CHECK THE OIL

Ensure the oil level is between the min and max marks on the dipstick. See
“Check the Oil level” on page 7 and top-up if necessary - (use SAE30
compressor oil available from your CLARKE dealer).

CLEAN THE AIR FILTER

The air filter must be examined monthly or more often in dusty conditions.

1. Remove the securing bolt and pull
the filter from the compressor.

2. Unclip the front and rear of the
filter and pull out the filter
element.

3. Clean the filter using a soft brush.

• If necessary, the filter can be

carefully cleaned in warm
soapy water.

• Rinse and let the filter dry

completely before refitting.

• If the filter or filter element is damaged, you must replace it.

4. Reassemble the filter and refit it to the compressor using the securing bolt.

REPLACING THE OIL

After the first 100 hours use, replace
the oil using CLARKE SAE30
compressor oil. Then replace the oil
after every 500 hours of operation or
every 6 months.

To empty the oil from the machine,
remove the oil drain plug from the
crankcase.

CHECKING THE NON-RETURN VALVE

If the reservoir pressure decreases for no apparent reason, it is possible that the
non-return valve is leaking. To check this:

1. Make sure that the reservoir is not
under pressure and the
compressor is switched OFF.

2. Examine the non-return valve,
and replace the gasket and valve
if necessary.
