Know Your Air Compressor
READ THiS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the illustrations with your unit to famiIiarize yourself with
the location of various controls and adjustments. Save this manual for future
reference.
Safety Valve
Description of Operation
Become familiar with these controls
before operating the unit.
On/Auto/Off Switch: Turn this switch
"On/Auto" 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 Vamve: 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 avaiIable at the outlet side
of the reguIatoK 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: ControIs 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.
Universam Quick-Connect Body:
The universal quick-connect body
accepts the three most popular styIes
of quick-connect plugs: industrial,
automotive (Tru-flate), and ARC. One
hand push-to-connect operation
makes connections simple and easy.
Brain Vamve:The drain valve is
located at the base of the air tank
and is used to drain condensation at
the end of each use.
13-ENG A09710

Cooming System (not shown}: This
compressor contains an advanced
design cooling system. At the heart of
this cooting 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.
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 Vatve: 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 wilI 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.
