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 nearest Clarke dealer.
4. Before carrying out any maintenance, make sure that the pressure is
released from the air tank 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 tank 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.

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 marked N or
coloured black.
• The BROWN wire must
be connected to the
terminal marked L or
coloured red.
• The YELLOW AND
GREEN wire must be
connected to the
terminal 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.
