Initial start procedure

If the compressor has not run for the past 6 months, it is strongly recommended to
improve the lubrication of the compressor element before starting.
To do so:

1. Disconnect the inlet hose.
2. Remove the unloader (UA).
3. Pour approximately 0.75 l (0.20 US gal, 0.17 Imp gal) of compressor oil into the

compressor element inlet. For oil specifications, see section

Oil specifications

4. Reinstall the unloader and reconnect the inlet hose.

Make sure that all connections are tight.

1. Check the oil level before starting.

The oil level should be between the oil filler neck (FC) and the bottom of the sight glass (Gl).
