On/AutO/OFF sWItCH
Place this switch (L) in the ON/AUTO
position to provide automatic power to the
pressure switch and OFF to remove power
at the end of each use. nOte: ALWAYS
ensure the switch (L) is in the OFF
position before removing or replacing
pressure switch cover.
Pressure sWItCH
The pressure switch (H) automatically starts the motor when the
air tank pressure 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
H
The regulated pressure gauge (D)
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
L
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.
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
G
The drain valve (B) 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.
