SAFETY VALVE
If the pressure switch does not shut off the air
G
compressor at its cut-out pressure setting, the
safety valve (G) will protect against high
pressure by popping out at its factory set
pressure (slightly higher than the pressure
switch cut-out setting).
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) indicates
D
E
C
B
the reserve air pressure in the tank.
REGULATED 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 regulated
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.
UNIVERSAL QUICK CONNECT BODY
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.
DRAIN VALVE
The drain valve (H) is located at the base of the air
H
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
above that required at the air outlet.
AIR INTAKE FILTER
The filter (J) is designed to clean air entering 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.
MOTOR OVERLOAD PROTECTOR
The motor has a 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. Set the On/Auto/Off lever to OFF and unplug unit.
2. Allow the motor to cool.
3. Plug the power cord into the correct branch circuit receptacle.
4. Set the On/Auto/Off lever to ON/AUTO position.
