CHECK VALVE
When the air compressor is operating, the check
F
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) indicates
D
B
C
the reserve air pressure in the tank.
OUTLET PRESSURE GAUGE
The outlet pressure gauge (C) 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.
REGULATOR
The regulator (D) controls the air pressure shown on the outlet
pressure gauge. Turn regulator knob clockwise to increase pres-
sure and counterclockwise to decrease pressure.
DRAIN VALVE
The drain valve (H) is located at the base
H
of the air tank and is used to drain conden-
sation 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
above that required at the air outlet.
MOTOR OVERLOAD PROTECTOR
This motor has a manual 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.
To restart:
1. Ensure the On/Off switch (A) is in the OFF
E
position.
2. Allow the motor to cool.
3. Depress the reset button (E) 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
.
AIR INTAKE FILTER
The filter (M) is designed to clean air entering
M
K
the pump. To ensure the pump continually
receives a clean, cool, and dry air supply the
filter must always be clean and the filter intake
must be free from obstructions.
