3-1.  OPERATION

This section deals with the proper methods of

system operation and shutdown.  These procedures

should be followed to prevent damage and ensure

efficient operation.

Start the compressor as follows:

1. Ensure the PTO is disengaged and the receiver

drain cock is open.

2. Start the truck engine and allow it to idle until it

reaches the proper operating temperature (refer to

the Owner’s Manual).

3. Depress the clutch, engage the PTO and

carefully release the clutch pedal.

4. Activate the engine speed control by closing the

receiver drain cock.  The compressor is now

operating and supplying working air.

WILL AUTOMATICALLY INCREASE DUE TO LOW
VOLUME OF AIR IN THE SYSTEM

Operating this unit in excess of 1000 RPM, measured at
the compressor flywheel, will void your warranty.  Engine
RPM may be different.

3-2.  SYSTEM SHUTDOWN

pressure and the truck engine will automatically idle

down.

2. Place the compressor control valve in the open

(off) position.

4. Open the receiver drain cock and discharge the

air in the receiver.
