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.

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. 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
a suitable 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 end cap shown.
