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 the 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.

SAFETY SYMBOLS
Read this instruction booklet carefully before positioning,
operating or adjusting the compressor.
Risk of electric shock. The compressor must be
disconnected from the mains supply before removing any
covers. Do not use in a damp environment.
Risk of accidental start-up. The compressor could start
automatically in the event of a power cut and subsequent
reset. Do not carry 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
motor housing removed.
Wear safety goggles and ear protectors when using this
compressor
This compressor produces a high sound level during
operation. Ear protection should be worn.

ELECTRICAL CONNECTIONS
BOXER 14/50P, 110V
Connect the mains lead to a suitable 110V (50Hz) electrical supply through an
approved plug or a suitably fused isolator switch.
If using a portable 110V transformer, make sure it has a rated capacity sufficient to take
the load of the air compressor.
BOXER 14/50P, 230V
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.
• The BLUE wire must be
connected to the
terminal which is marked
N or coloured black.
•TheBROWNwiremustbe
connected to the
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.

again when the pressure in the
reservoir decreases.
CHECK THE SAFETY VALVE
To make sure that the safety valve works correctly.
1. Pull on the ring attached.
• Air will be released when you
pull on the ring 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.
SET 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.
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.
• You will hear a hissing sound as
the reservoir depressurises.
4. Do not leave the compressor
unattended if the reservoir is pressurised.
WARNING: ALWAYS SET THE PRESSURE REGULATOR TO ZERO BEFORE YOU
REMOVE OR REPLACE A TOOL.

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.
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.

MAINTENANCE
DRAIN THE RESERVOIR (DAILY)
After use, always open the drain valve to make sure that any condensate is
drained off.
CHECK OIL (DAILY)
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 Clarke SAE30
compressor oil, available from your local dealer).
CLEAN THE AIR FILTER (MONTHLY)
The air filter must be examined monthly, 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.
WARNING: MAKE SURE THAT THE COMPRESSOR IS DISCONNECTED FROM
THE ELECTRICAL SUPPLY BEFORE CARRYING OUT ANY MAINTENANCE

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.
CHECK THE NON-RETURN VALVE (EVERY 6 MONTHS)
If the reservoir pressure decreases for no apparent reason, it is possible that the
non-return valve is leaking. To checkthis,:
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.
