CHECK VALVE
When the air compressor is operating, the check
valve (F) 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.
TANK PRESSURE GAUGE
The tank pressure gauge (B)
indi-cates the reserve
pressure in the tank.
OUTLET PRESSURE GAUGE
The outlet pressure gauge
(C) indicates the air pressure
available at
outlet side of the
controlled by the regulator and is always less than or equal to the
tank pressure.
REGULATOR
The regulator (D) controls the air pressure shown on the outlet
pressure gauge. Turn regulator knob clockwise to increase
pressure and counterclockwise to decrease pressure.
UNIVERSAL QUICK CONNECT BODIES
The universal quick connect body (E) accepts the three most
popular styles of quick connect plugs: Industrial, automotive, and
ARO. One hand push-to-connect operation makes connections
simple and easy. The two quick connect bodies allow the use of
two tools at the same time.

DRAIN VALVE
The drain valve (H) is located at the base
of the air tank and is used to drain
condensation at the end of each use.

See Draining Air Tank under Maintenance.
COOLING SYSTEM
This compressor contains an advanced design cooling system.
It is normal for this fan to blow air through the vent holes in large
amounts. The cooling system is working when air is expelled.
AIR COMPRESSOR PUMP
The pump compresses air into the air tank. Working air is not
available until the compressor has raised the air tank pressure
E
above that required at the air outlet.
MOTOR OVERLOAD PROTECTOR
This motor has a manual thermal overload protector. If the motor
is
overheats for any reason, the overload protector will shut off the
motor. The motor must be allowed to cool down before restarting.
To restart:
1. Ensure the On/Off switch (A) is in the
OFF position.
2. Allow the motor to cool.
3. Depress the reset button (M) on the
motor.
OIL DIPSTICK
The oil dipstick (K) indicates the amount
of oil in the pump. Check pump oil
daily, see Compressor Pump Oil under
Maintenance.
