CHECK VALVE (A-FIG.3). When the air compressor is operating, the check valve "opens", allowing
compressed air to enter the air tanks. When the air compressor reaches "Cut-Out" pressure, the
check valve "closes", allowing air pressure to remain inside the air tanks. Note: (A) Fig.5 is not a
check valve, it is a two way connector which allows you to connect an air hose and air tool to the
detachable tank.
ON/AUTO-OFF SWITCH (B) FIG.3. Turn this switch ON by raising lever upwards to provide power
to the automatic pressure switch and lower lever to turn compressor OFF.
PRESSURE SWITCH (D) FIG.3. The pressure switch automatically starts the motor when the tank
pressure drops below the factory set "Cut-In" pressure. It also stops the motor when the air tank
pressure reaches the factory set "Cut-Out" pressure.
REGULATOR (B) FIG.4. The air pressure coming from the air tanks is controlled by the regulator.
Turn the regulator knob clockwise to increase pressure and counterclockwise to decrease pressure.
To avoid minor readjustment after making a change in the pressure setting, always approach the
desired pressure from a lower pressure. When reducing from a higher to a lower setting, first reduce
the pressure less than that desired, then bring it up to the desired pressure. Depending on the air
requirements of each particular accessory, the outlet regulated air pressure may have to be
adjusted while operating the accessory.
OUTLET PRESSURE GAUGE (D-FIG.4). The main outlet pressure gauge indicates the air pressure
available at the outlet side of the regulator. The pressure is controlled by the regulator and is always
less than or equal to the tank pressure.
TANK PRESSURE GAUGES (A-FIG.4, B-FIG.5). The main tank pressure gauge (A) Fig.4 indicates the
reserve air pressure in both tanks (if detachable tank is connected). The detachable tank pressure
gauge (B) Fig.5 indicates the reserve air pressure in the detachable tank only.
DRAIN VALVES (A & B FIG.6). The drain valves are located at the base of each air tank and are
used to drain condensation from the tanks to prevent corrosion, should be done at the end of each use.
QUICK CONNECT COUPLERS (C-FIG.4). Connect up to 2 air tools.
DETACHABLE TANK AIR PRESSURE CUT-OFF VALVE (C) FIG. 3. Close this cut-off valve before
disconnecting detachable tank. When detachable tank is connected to compressor, this cut-off valve
must be open to allow air pressure to build inside detachable tank.
DETACHABLE TANK AIR SUPPLY HOSE (D-FIG. 5). The air supply hose must be connected to
detachable tank quick connect coupler to allow air pressure to build. Disconnect this air supply hose
when detaching upper tank is needed.
MOTOR THERMAL OVERLOAD PROTECTOR (RESET (A) FIG. 7). The electric motor has an
automatic thermal overload protector. If the motor overheats for any reason, the thermal overload
protector will shut off the motor. The motor must be allowed to cool before restarting. Press the reset
button (A).
PRESSURE RELEASE VALVE. The pressure release valve located on the side of the pressure
switch, is designed to automatically release compressed air from the compressor head and the
outlet tube when the air compressor reaches "Cut-Out" pressure or is shut off. The pressure release
valve allows the motor to restart freely. When the motor stops running, air will be heard escaping
from this valve for a few seconds. No air should be heard leaking when the motor is running, or
continuous leaking after unit reaches "Cut-Out" pressure.
SAFETY VALVES (C-FIG.5, C-FIG.6). If the pressure switch does not shut off the air compressor at
its "Cut-Out" pressure setting, the safety valves will protect against high pressure by "popping out"
at their factory set pressure (slightly higher than the pressure switch "Cut-Out" setting).
WARNING!: If the safety valves don't work properly, over pressurization may occur, causing air tank
rupture or an explosion. Daily pull the ring on each safety valve to make sure that they operate freely.
If a valve is stuck or does not operate smoothly, it must be replaced with the same type of valve
before operating again.
