SAFETY PRECAUTIONS
1. Compressed air is dangerous, NEVER direct a jet of air at people or animals, and
NEVER discharge compressed air against the skin.
2. DO NOT operate your compressor with any guards removed.
3. Electrical or mechanical repairs should only be carried out by a qualified engineer. If
problems occur, contact your Clarke dealer.
4. Before carrying out any maintenance, ensure the pressure is expelled from the air
receiver, and the machine is disconnected from the mains 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 machine.
7. DO NOT operate in wet or damp conditions. Keep the machine dry at all times.
Similarly, a clean atmosphere will ensure efficient operation. Do not use in dusty or
otherwise dirty locations.
8. Some of the metal parts can become quite hot during operation. Take care not to
touch these until the machine has cooled down.
9. Always adjust the pressure regulator to the recommended setting for the particular
spray gun or tool being used.
10. When spraying flammable materials e.g. cellulose paint, ensure that there is
adequate ventilation and keep clear of any possible source of ignition.
11. Protect yourself. Think carefully about any potential hazards which may be created
by using the air compressor and use the appropriate protection. e.g. Goggles will
protect your eyes from flying particles. Face masks will protect you against paint
spray and/or fumes.
12. Before spraying any material always consult paint manufacturers instructions for
safety and usage.
13. Do not exert any strain on electrical cables and ensure that air hoses are not angled
or wrapped around machinery etc.
14. When disconnecting air hoses or other equipment from your compressor ensure that
the air supply is turned off at the machine outlet and vent all pressurised air from
within the machine 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. Always ensure that all individuals using the compressor have read and fully
understand these Operating Instructions.
17. Ensure that any equipment or tool used in conjunction with your compressor, has a
safety working pressure exceeding that of the machine.
WARNING: AS WITH ALL MACHINERY, THERE ARE CERTAIN HAZARDS
INVOLVED WITH THEIR OPERATION AND USE. EXERCISING RESPECT AND
CAUTION WILL CONSIDERABLY LESSEN THE RISK OF PERSONAL INJURY.
HOWEVER, IF NORMAL SAFETY PRECAUTIONS ARE OVERLOOKED, OR
IGNORED, PERSONAL INJURY TO THE OPERATOR MAY RESULT.

ELECTRICAL CONNECTIONS
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.
IMPORTANT: The wires in the mains lead are coloured in accordance with the
following code:
Green & Yellow - Earth
Blue - Neutral
Brown - Live
• Connect GREEN & YELLOW cord to terminal marked with a letter “E” or
Earth symbol “ ” or coloured GREEN or GREEN & YELLOW.
• Connect BROWN cord to terminal marked with a letter “L” or coloured
RED.
• Connect BLUE cord to terminal marked with a letter “N” or coloured
BLACK.
If this appliance is fitted with a plug which is moulded onto the electric cable
(i.e. non-rewireable) please note:
1. The plug must be thrown away if it is cut from the electric cable. There is a
danger of electric shock if it is subsequently inserted into a socket outlet.
2. Never use the plug without the fuse cover fitted.
3. When replacing a detachable fuse carrier, ensure the correct replacement
is used (as indicated by marking or colour code).
4. Replacement fuse covers can be obtained from your local dealer or most
electrical stockists.
FUSE RATING
The fuse in the plug must be replaced with one of the same rating (13 amps)
and this replacement must be ASTA approved to BS1362.
If in any doubt, consult a qualified electrician. DO NOT attempt any repairs
yourself.
WARNING: THIS APPLIANCE MUST BE EARTHED

PREPARING FOR USE
Before connecting your compressor to the mains supply, check the following:-
• Firstly, ensure the compressor is on level ground. Do not allow it to run if
it is standing on an incline.
• Check also that the mains voltage corresponds with that shown on
the data label on the side of the compressor.
• The ON/OFF switch is in the OFF
position.
• Remove any transit caps from
the air inlets and replace them
with the air inlet filters supplied.
ADDING OIL
The compressor is supplied without any
oil inside.
1. Make sure that the oil level is half
way up the oil sight glass
2. If not, remove the oil cap and top
up the reservoir
• Only use Clarke synthetic
compressor oil, available from
your Clarke dealer (Part No.
3050795).

SWITCHING THE AIR COMPRESSOR ON
1. To start the compressor, turn the
ON/OFF switch to the ‘I’ (ON)
position - the motor should start
immediately.
NOTE: If the motor fails to start
immediately, the air receiver
may already be full of air.
Check the tank pressure
gauge (shown on the right).
If you release air, by opening
the air outlet tap, the motor
will start automatically once
the cut-in pressure is
reached.
2.
A
B
C
D
E
Allow the compressor to run for 10
- 15 seconds, with the air outlet
tap, (A) open.
• This will distribute the lubricating
oil.
3. Close the outlet tap and connect
asuitable air hose to the filter/
regulator outlet (B). Connect the
other end to the equipment to be
used.
4. Check the safety valve by pulling
on the ring shown, air should hiss
out when pulled.

7
5. Adjust the pressure regulator.
• To do this, lift the pressure regulator knob (C), and turn it clockwise to
increase the pressure, anticlockwise to decrease the pressure. The
pressure is shown on the outlet gauge, (D).
• To lock the pressure regulator knob, push the pressure regulator knob
down until it clicks into place.
IMPORTANT: Always refer to the accessory manufacturers recommendations for
optimum operating pressures for their equipment.
6. With operating pressure set, open the air outlet tap.
NOTE: If the machine pumps continuously without cutting out then the
compressor is too small for the application/tool being used, and
damage may result. Consult your Clarke dealer.
NOTE: DO NOT exceed the duty cycle for the machine (see
Specifications).
SHUTTING DOWN THE COMPRESSOR
1. To shut off the compressor, simply turn the ON/OFF switch to the O (OFF)
position.
2. Close the air outlet tap and trigger the equipment (spray gun, air tool etc.)
to release air from the air hose before disconnecting the hose from the
machine.
3. Before transporting your
compressor or when leaving
overnight, expel all air from the
receiver by opening the vent
valve.

8
DRAINING THE TANK
1. Pressurise the reservoir slightly and
then turn the compressor off.
2. Attach the small hose supplied to
the vent valve as shown.
3. Take the compressor to the sink
and place the free end of the
small hose in the sink.
4. Slowly open the vent valve.
5. When the reservoir has been
drained, re-tighten the vent valve and remove the hose.
DRAINING THE AIR OUTLET FILTER
1.
Valve (E)
Drain any liquid that may have
accumulated in the air filter
chamber, by first twisting and then
pushing the valve (E) upwards.
