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 touch/
remove these until the compressor has cooled down.
9. When spraying flammable materials e.g. cellulose paint, ensure that there is
sufficient airflow and keep clear of any source of ignition.
10. Before spraying any material always consult paint manufacturers instructions for
safety and usage.
11. Protect yourself. Goggles will protect your eyes from flying particles. Face masks will
protect you against paint spray and fumes.
12. DO NOT apply strain to electrical cables and make sure that air hoses are not kinked
or wrapped around the compressor.
13. 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.
14. Make sure that children and animals are kept well away from the compressor and
any equipment attached to it.
15. Make sure that all individuals using the compressor have had the necessary training
