DESCRIPTION
OF
OPERATION
Air Compressor Pump:
To compress air, the piston
movesupanddowninthecylinder.Onthedownstroke,air
isdrawninthroughtheairintakevalves.Theexhaustvalves
remain closed. On the upstroke of the piston, air is
compressed.Theintakevalvescloseandcompressedair
isforcedoutthroughtheexhaustvalves,throughtheoutlet
tubes, through the check valve and into the air tank.

air tank. When the air compressor reaches “cut-out”
pressure,thecheckvalve“closes”,allowingairpressureto
remaininsidethe air tank.

Regulator:
The air pressurecomingfrom the air tank is
controlledbytheregulator. Turntheregulatorknobclock-

from a higher to a lower setting, first reduce to some

INSTALLATION AND BREAK4N PROCEDURES
Location
of
the Air Compressor
Your compressor comes to you completely assembled
and ready for use. Operatethe air compressorin a dry,
clean, coolandwellventilatedarea. The aircompressor

Clean or blow
off
dust or dirt that collects on the air
compressor. A clean air compressor runs cooler and
provideslongerservice. Theventilationopeningsonyour
