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.
