FEATURES (Fig. 1)
ON/OFF SWITCH
Place this switch (L) in the ON position to
provide automatic power to the pressure
switch and OFF to remove power at the
end of each use.
PRESSURE SWITCH
The pressure switch (H) automatically
starts the motor when the air tank pres-
sure 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 (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 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 (K) indi-
cates the reserve air pressure in
the tank.
REGULATED PRESSURE GAUGE
The regulated pressure gauge (D) indicates the air pressure avail-
able at the outlet side of the regulator. This pressure is controlled
by the regulator and is always less than or equal to the tank pres-
sure.
REGULATOR
The regulator (F) controls the air pressure shown on the regulated
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. 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 (M) is located atthe base of
the air tank and is used to drain condensa-
tion 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.
