Know Your Air Compressor
READ THIS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING YOUR UNIT. Compare the illustra-
tions with your unit to familiarize yourself with the location of various controls and adjustments. Save this manual
for future reference.
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 use.
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 high-
er 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 reg-
ulator 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.
Regulator
Drain Valve: The drain
valve is located at the
base of the air tank and is
used to drain condensa-
tion at the end of each
Valve
use.
Cooling System (not shown): This compressor con-
tains an advanced design cooling system. At the heart
of this cooling system is an engineered fan. It is per-
fectly 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.
Air Compressor Pump (net 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", allow-
ing 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
pressure release valve located Release
on the side of the pressure Valve
switch, is designed to automati-
cally 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 leak-
ing when the motor is running, or continuous leaking
after unit reaches "cut-out" pressure.
