SAFETY VALVE
If the pressure switch does not shut off the air
compressor at its cut-out pressure setting, the
safety valve (G) will protect against high pres-
sure 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
the reserve air pressure in the tank.
OUTLET PRESSURE GAUGE
The outlet pressure gauge (C) indi-
cates the air pressure available at the
outlet side of the regulator. This pres-
sure 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.
UNIVERSAL QUICK CONNECT BODIES
The universal Quick Connect body (E) accepts the three most
popular styles of Quick Connect plugs: Industrial, automotive, and
ARO. 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
Maintenance.
G
COOLING SYSTEM
F
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
E
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.

INSTALLING HOSES
WARNING: Risk of unsafe operation. Firmly grasp hose in hand
when installing or disconnecting to prevent hose whip.
1. Ensure regulated pressure gauge reads 0 PSI (0 kPa).
2. Grasp the hose at the Quick Connect plug and push the plug
3. Grasp the hose and pull to ensure coupler is seated.
