Operating Instructions
www.CH-Commercial.com
Before starting the compressor, thoroughly read all component
instruction manuals, especially the engine manual.
A belt guard must be installed before operating the unit.
GETTING STARTED
1. Donotoperatecompressorhigherthantheratedspeed.Excessiveenginespeeds
can damage the compressor and engine�
Do not disconnect battery from engine ignition while compressor is
running (models w/electric start only).
2� Check the oil level in the compressor and engine crankcase and add oil if required�
3. Fillfueltankwithclean,fresh,regularunleaded(orregularleadedifnotavailable)
grade of automotive gasoline� Do not mix oil with gasoline�
4. Beforestartingthecompressor,puttoggleleverinUnloadposition.Afterengine
reachesfullspeed,fliptogglelevertoLoadedposition(SeeFigure7).
5� When putting unit into service for the first time, the compressor should be run
continuously for one hour to allow proper seating of the piston rings�
a� Open drain cock on the tank and run the compressor unloaded for 60 minutes
(SeeFigure8).
b� Turn off the compressor and close drain cock� The compressor is now ready for
use�
6� On cold weather start-up, run unit unloaded for 10-20 minutes to warm up
compressor and engine�
7. Somevibrationiscommonforthefirst2to3hoursofoperation.Thisvibrationwill
decrease after the belt and pulley seat�
If the compressor is run under humid conditions for short periods of time, the
humidity will condense in the crankcase and cause the oil to look creamy� Oil
contaminated by condensed water will not provide adequate lubrication and must be
changed immediately� Using contaminated oil will damage bearings, pistons, cylinders
and rings and is not covered under warranty� To avoid water condensation in the oil,
periodically run the compressor with tank pressure at 20 psi under maximum pressure
settingbyopeningthedraincockoranairvalveconnectedtothetankorhose.Run
the pump for an hour at a time at least once a week or more often if the condensation
reoccurs�
Change oil after first 50 hours of operation.
CONTINUOUS RUN OPERATION
Continuous run operation is designed for gasoline engine units to ensure the required
air pressure is always available and to eliminate the need for frequent starting� The
engine and the pump continuously run to keep the air tank at maximum operating
pressure�
IDLEDOWN/UNLOADING
This unit is equipped with idle down/unloading control� To check operation:
1. Closeoutletvalve(SeeFigure9).
2� Start compressor and allow pressure to reach proper limit of control valve, which is
setat175psifor2stagecompressor.Atthispoint,thecompressorshouldunload
through the breather bushing on control valve and the engine should idle down�
3� Open outlet valve and allow pressure in tank to drop to lower limit of control valve
whichispresetat145psi(2stage).Atthispointthecontrolvalveshouldclose
allowing the compressor to begin loading the tank instead of discharging through
the breather bushing�
