3.3 Start-up

In connection with the first start-up or after prolonged downtime, the following procedure should be used:

A Check oil level.

B Check that the oil does not contain water or other substances which will impair its quality.

C Check the compressor valves and apply oil to the cylinders.

D Turn over the compressor by hand, removing the suction valve load by means of the manual unloader. (Set

the lever in the vertical position.)

E Check the cooling water circulation.

F Check that the non-return valve between the compressor and the air reservoir is open.

G Set the manual drain valves in the open position.

H Start the compressor.

I If everything functions correctly, the drain valves and the unloader should be set to the operating positions. (Set the unloader lever in the horizontal position.)

The compressor should be allowed to run for a few minutes before subjecting it to maximum working pressure.
