Know Your Air Compressor
READ THIS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with
the location of various controls and adjustments. Save this manual for future
reference.
Outlet
Pressure
Gauge
Description of Operation
Become familiar with these controls
before operating the unit.
On/Auto/Off Switch: Turn this switch
ON to provide automatic power to
the pressure switch and OFF to
remove power at the end of each
usa.
Pressure Switch: The pressure
switch automatically starts the motor
when the air tank pressure drops
below the factory set "cut-in"
pressure. It stops the motor when the
air tank pressure reaches the factory
set "cut-out" pressure.
Safety Valve: If the pressure switch
does not shut off the air compressor
at its "cut-out" pressure setting, the
safety valve will protect against high
pressure by "popping out" at its
factory set pressure (slightly higher
than the pressure switch "cut-out"
setting).
Outlet Pressure Gauge: The outlet
pressure gauge indicates the air
pressure available at the outlet side
of the regulator. This pressure is
controlled by the regulator and is
always less than or equal to the tank
pressure.
Tank Pressure Gauge: The tank
pressure gauge indicates the reserve
air pressure in the tank.
Regulator: Controls the air pressure
shown on the outlet pressure gauge.
Pull the knob out and turn clockwise
to increase pressure and
counterclockwise to decrease
pressure. When the desired pressure
is reached push knob in to lock in
place.
Drain Valve: The drain valve is
located at the base of the air tank
and is used to drain condensation at
the end of each use.
Cooling System (not shown): This
compressor contains an advanced
design cooling system. At the heart
of this cooling system is an
engineered fan. It is perfectly normal
for this fan to blow air through the
vent holes in large amounts. You
know that the cooling system is
working when air is being expelled.
13- ENG D29761

Air Compressor Pump (not shown):
Compresses air into the air tank.
Working air is not available until the
compressor has raised the air tank
pressure above that required at the
air outlet.
Check Valve: When the air
compressor is operating, the check
valve is "open", allowing compressed
air to enter the air tank. When the air
compressor reaches "cut-out"
pressure, the check valve "closes",
allowing air pressure to remain inside
the air tank.
Pressure Release Valve: The
pressure release valve located on the
side of the pressure switch, is
designed to automatically release
compressed air from the compressor
head and the outlet tube when the air
compressor reaches "cut-out"
pressure or is shut off. The pressure
release valve allows the motor to
restart freely. When the motor stops
running, air will be heard escaping
from this valve for a few seconds.
No air should be heard leaking when
the motor is running or after the unit
reaches "cut-out" pressure.
Motor Overload Protector: The
motor has an automatic reset thermal
overload protector. If the motor
overheats for any reason, the
overload protector will shut off the
motor. The motor must be allowed to
cool down before restarting. The
compressor will automaticafly restart
after the motor cools.
How to Use Your Unit
How to Stop:
1. Set the On/Auto/Offleverto
