Operating Instructions

IMPORTANT: Check motor rotation before operating the compressor�
All lubricated compressor pumps discharge some condensed water and oil with the
compressed air� Install appropriate water/oil removal equipment and controls as
necessary for the intended application�
Failure to install appropriate water/oil removal
equipment may result in damage to machinery or workpiece.
GUARDING
The belt guard provided must be installed before operating
the unit.
All moving parts must be guarded� All electrical covers must be installed
before turning on the power�
RECOMMENDED BREAK-IN PERIOD
The compressor should be run continuously for one hour to allow proper seating of the
piston rings�
1� Open drain cock completely and run the compressor for 60 minutes�
2� Turn off the compressor and close drain cock� The compressor is now ready for use�
PRESSURE SWITCH, START - STOP
NOTE:Thiscompressorhasamaximumoperatingpressureof175psi.Donotalter
pressure settings on control components above this limit�
The compressor unit starts and stops based on preset pressure switch settings of 145
psi cut-in and 175 psi cut-off� The pressure switch contains an unloader which is a
small valve that vents air to allow the motor to start easily (see Figure 15)�
The unloader valve on the pressure switch should hiss for a short period of time when
the compressor shuts off� This relieves the head and the exhaust tubing of any pressure
andallowsthecompressortostartundernoload.Becausecompressorshavehigh
starting torque the unloader is necessary for proper starting of the compressor�
The check valve is a one way valve that keeps the air in the tank when the unit shuts off�
The easiest way to determine if the check valve is working properly is to make sure that
the pressure switch unloader quits hissing after the compressor shuts off� The hissing
should last for several seconds and then quit�
CRANKCASE BREATHER
Duringsevereoperatingconditionsorinitialstart-up,someoilmayaccumulate
at the crankcase breather opening� This is normal and will diminish as the pump
accumulates run time and the piston rings become fully seated�
DRAINING TANK
Condensate must be drained from the tank daily� On Shop Air Series models use
manual tank drain (see Figure 16)� Automotive Series models include an automatic
tank drain which must be installed (see Figure 17)� Refer to instructions provided with
the automatic drain�
