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
available at the outlet side of the regulator. This pressure is
controlled by the regulator.
reGulAtOr
The regulator (F) 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. The
regulated pressure range is 7–150 psi.
WARNING: Risk of Bursting. Too much air pressure causes a
hazardous risk of bursting. Check the manufacturer's maximum
pressure rating for air tools and accessories. The regulator outlet
pressure must never exceed the maximum pressure rating.

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 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
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.
