conditions are met.
1. Voltage supply to circuit must
comply with the National
Electrical Code.
2. Circuit is not used to supply any
other electrical needs.
3. Extension cords comply with
specifications.
4. Circuit is equipped with a 15 amp
circuit breaker or 15 amp time
delay fuse. NOTE: If compressor

Description of Operation
Become familiar with these controls
before operating the unit.
On/Auto/Off Lever: Place this switch
in the "On/Auto" position to provide
automatic power to the pressure
switch and "Off" to remove power at
the end of each use.
Pressure Switch (not shown): 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).
Tank Pressure Gauge: The tank
pressure gauge indicates the reserve
air pressure in the tank.
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.

Outlet
Pressure
Gauge
Regulator
Regulator: Controls the air pressure
shown on the outlet pressure gauge.
Turn regulator knob clockwise to
increase pressure and counterclockwise to decrease pressure.
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.
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.
Drain Valve:
The drain valve
is located at
the base of the
air tank and is
Drain
Valve
used to drain
condensation at the end of each use.
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.
Check Valve
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.
Pressure

Valve
Motor Overload Protector (not
shown): 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 automatically restart
after the motor cools.
