AirCompressorPump: Tocompress air, the piston m oves up
and down
in the cylinder. On the downstroke, air is drawn in
through the air intake valves. The exhaust valves remain
closed, On the upstroke of the piston, airiscompressed. The
intake valves close and compressed air isforcedoutthrough the
exhaust vaives, through the outlet tube, through the check
valve and into the air tank. Working air is not available until
the corn pressor has raised the air tank pressure above that
required at the air outlet,
Check Valve: When the aircompressor is operating, the check
valve is "open". altowing compressed air to enterthe airtank.
Whenthe aircompressorreaches"cut-out" pressure, thecheck
valve "closes", allowing air pressure to remain inside the air
tank.
Pressure Release Valve: The pressure t_leasevalve located on
the side of the pressure switch, is designed to automatically
releasecompressed air from the comp_essorhead and the outlet
tube widen the aircompressor reaches"cut_out" pressure or is
sh[-t.,_ff, if tile air is riot released, the motor will not be able to
staR. The pressure release valve allows the motor to restart
freely, wnen the motorstops runr;ing, airwill be hear(,'escaping
from _?:e vaive for afewseconds. No.si!-si;ould be leaking when
the rr,o',or is running.
Pr_ssu_'e Switch: The pressure sv,;itch automaticaily starts the
motor wi_en {he air tank pressure dnups below the factory set

SafetyValve: tfthe pressure switch does notshutoffthe air
compressor at its cut-out pressure setting, the safetyvatve will
protect the tank against high pressure by "popping out" at its
factory, set p_essure(slightly higherthan the pressure switch cut-
out setting}.
Regulator: The air pressure coming from the air tank is
controlled bythe regulator. Tur n the regulator knob clockwise
to increase pressureand counter-ctockwisetodecrease pres-
sure. To avoid minor readjustment after making a change in
pressure setting, always approach the desired pressure from a
lower pressure, When reducing from a higher toa lower setting,
first reduce to some pressure less than that desired, then bring
uptothedesired pressure. Depending onthe air requirements
of each particular accessory, the outlet regulated air pressure
may have to be adjusted while operating the accessory.
OutLet Pressure Gauge: The outlet pressure gauge indicates
theair pressure available attheoutlet side oftheregulator-This
pressure is controlled bythe regulator and is always less orequa!
tothe ta, n k pressure. See,Operating Procedures".
Tank Pressure Gauge: The tank pressure 9auge indicates the
resen_e-zir pressure in the tank.
Coo!in9 System: ihis co_,npressor cont_4ns an advancedde-
sign coo!irg system. At the heart of this cooiing system is an
er',_.kzse.*ed fan. It is perfectly normal for this fan to blow air
_,h_ ough the,:ent hoies in large amounts. You know that the
cooli_ _g system is working when air is being expelled.
