- Check blade wear by measuring distance from the corner of
the rotor slot to the blade. Replace blade before
5/8” wear is reached.
Blade wear can be checked through the
suction port with calipers,after machine is turned off and cool.

Operation

• Inspect compressor mounting, driveline, PTO, and air filter for
integrity.
• Check that the bleed valve is set to vent to atmosphere.
• Follow trailer instructions regarding product hose connection
and valve operation.
• Slowly engage PTO with engine at idle, and bring up to
operating speed shown on label.

Incorrect speed will cause compressor failure.

• Lock engine at recommended speed. The engine speed
must remain constant throughout the discharge cycle.
• Turn bleed valve to direct air into the tank.
• Unload trailer as per trailer manufacturer’s recommendation.
Do not exceed maximum tank pressure.
• If relief valve is operating, adjust bleed valve to reduce tank
pressure.

Note:

Do not decrease engine speed to reduce pressure.
Too low (or high) speed will cause compressor failure.

• When unloading is completed, open the bleed valve and
reduce pressure as per trailer manufacturer’s instructions.
• Check that all valves are in their correct shutdown positions.
• Disengage PTO.

Hydraulic Drive Operation

• Engage PTO and set correct engine speed.
• Operate the selector valve to start the compressor.
• Continue as PTO drive, use the selector valve to stop the
compressor when unloading is complete.
