OPERATION
Know Your Air Compressor
READ THIS OWNER’S MANUAL AND SAFETY RULES BEFORE OPERATING YOUR UNIT. Compare the illus-
trations with your unit to familiarize yourself with the location of various controls and adjustments. Save this
manual for future reference.
Drain Valve (not shown):
The drain valve is located
at the base of the air tank and is used to drain con-
densation at the end of each use.
Motor Thermal Overload Protector (not shown):
The electric motor has an automatic thermal over-
load protector. If the motor overheats for any reason,
the thermal overload protector will shut off the motor.
The motor must be allowed to cool before restarting.
ON/AUTO - OFF Switch (A):
Turn this switch ON to
provide automatic power to the pressure switch and
OFF to remove power at the end of each use.
Air Intake Filter (not shown):
This filter is
designed to clean air coming into the pump. This fil-
ter
must
always be clean and ventilation openings
free from obstructions. See "Maintenance".
Air Compressor Pump (not shown):
Compresses
air into the air tank.
Check Valve (not shown):
When the air compres-
sor 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 (not shown):
The pres-
sure release valve located on the side of the pres-
sure 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 continuous
leaking after unit reaches cut-out pressure.
Pressure Switch (B):
The pressure switch automati-
cally 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 (C):
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 set-
ting).
Outlet Pressure Gauge (D):
The outlet pressure
gauge indicates the air pressure available at the out-
let side of the regulator. This pressure is controlled
by the regulator and is always less than or equal to
the tank pressure. All four outlets operate at this
pressure.
Tank Pressure Gauge (E):
The tank pressure
gauge indicates the reserve air pressure in the tank.
The “quadraport” is equipped with an tank pressure
gauge to be read at a remote location.
Regulator (F):
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.
Portable “Quadraport” Control Panel (G):
Permits
remote air regulation and control closer to work area,
includes four high-flow industrial/automotive style
compatible quick-connects, large gauges, and a
