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 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 to touch
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 a safety goggles and ear protectors when using this

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.
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.
If the colours of the wires in the power cable do not agree with the markings
on the plug:
• The BLUE wire must be
connected to the
terminal which is
marked N or coloured
black.
• The BROWN wire must
be 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.
WARNING! Read these electrical safety instructions thoroughly
before connecting the product to the mains supply.
WARNING! The wires in the power cable of this product are
coloured in accordance with the following code:
Blue = Neutral Brown = Live Yellow and Green = Earth
Plug must be BS1363/A approved.
Always fit
Ensure that the outer sheath of

hand outlet valve will only supply the full reservoir pressure and is not
adjustable.
1. Use the pressure regulator to set
the output pressure of the left
hand outlet valve.
• Turn clockwise to increase the
pressure.
• Turn counterclockwise to
decrease the pressure.
GAUGES
1. The reservoir pressure gauge
shows the current pressure in the
reservoir.
2. The outlet pressure gauge shows
the ‘user set’ outlet pressure. This
can be adjusted as shown above.
REMOVING TOOLS FROM THE AIR HOSE
1. Push down on the On/Off button
to stop the compressor.
WARNING: ALWAYS SET THE PRESSURE REGULATOR TO ZERO BEFORE YOU
REMOVE OR REPLACE A TOOL.

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 one of the outlet
valves to depressurise the reservoir.
• You will hear a hissing sound as
the reservoir depressurises.
• Do not leave the compressor
unattended if the reservoir is pressurised.
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.

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
DRAIN THE RESERVOIR (DAILY)
After use, always open the drain valve to make sure that any condensate is
drained off.
CLEAN THE AIR FILTER (MONTHLY)
The air filter must be examined monthly, more often in dusty conditions,
1. Remove the filter from the
compressor.
2. Remove the filter cover from the
filter.
3. Remove the filter from the filter
cover.
4. Clean the sponge and the filter
cover using a soft brush.
• If necessary, the filter can be
carefully cleaned in warm
soapy water.

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 check,
1. Make sure that the reservoir is not
under pressure and the
compressor is switched OFF and
disconnected from the power
supply.
2. Examine the non-return valve,
and replace the gasket and valve
if necessary.
