OPERATION CONTROLS
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
tothe 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.

BREAK-IN PROCEDURES & OPERATION
ASSEMBLY AND LOCATION OF THE AIR COMPRESSOR
Your compressor comes almost completely assembled, the air filter must be installed and the oil cap must be replaced with the oil
breather cap (A) Fig.9. Operate the air compressor in a dry, clean, cool, well ventilated area. The air compressor pump and case are designed
toallow for proper cooling. Clean or blow off dust or dirt that collects on the air compressor. A clean air compressor runs cooler and provides
longer service. The ventilation openings on your air compressor are necessary to maintain proper operating temperature. Do not place rags or
other containers on or near these openings.
ADDITIONAL REGULATORS AND CONTROLS
Since the air tank pressure is usually greater than that which is needed, a regulator is employed to control the air pressure ahead of any
individual driven device. Seperate air transformers which combine the function of air regulation, moisture and dirt removal should be used where
applicable.
BREAK-IN PROCEDURES
NOTE: SERIOUS DAMAGE MAY RESULT IF THE FOLLOWING BREAK-IN INSTRUCTIONS ARE NOT CLOSELY FOLLOWED. THIS
PROCEDURE IS REQUIRED BEFORE THE AIR COMPRESSOR CAN BE PUT INTO SERVICE, AFTER REPLACING THE CHECK VALVE,
AND WHEN THE PISTON OR THE CYLINDER SLEEVE IS REPLACED.
1. Fill crankcase with oil to the red dot of oil sight glass as described in “Changing Oil” in the maintenance section on the following page.
2. Set the pressure switch lever to the “OFF” position.
3. Plug the power cord into the correct 120V branch circuit receptacle.
4. Fully open the drain valves (A &B) Fig.6, by turning them counterclockwise, to prevent air pressure build-up in the tanks.
5. Move the pressure switch lever to “ON/AUTO”. The compressor will start.
6. Run the compressor for 15 minutes. Make sure the drain valves are open and there is no tank pressure build-up by watching the tank
pressure gauge.
7. After 15 minutes, close the drain valves by turning them clockwise. The air receiver will fill to “Cut-Out” pressure and the motor will stop. The
compressor is now ready for use.
OPERATING PROCEDURES
Preparation for use:
1. Before attaching an air hose or accessories, make sure the OFF/AUTO lever is set to “OFF” and the air regulator is closed. Once this is done,
you can now attach a hose or an accessory.
WARNING: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 of the tool being used.
2. Turn the “ON/AUTO-OFF” lever to “ON/AUTO” and allow tank pressure to build. Motor will stop when tank pressure reaches “Cut-Out”
pressure.
3. Open the regulator by turning it clockwise. Adjust the regulator to the correct pressure setting. The compressor is ready for use.
4. Always operate the air compressor in well ventilated areas; free of gasoline or other solvent vapors. Do not operate the compressor near the
spray area.
After Use:
5. Set the “ON/AUTO-OFF” lever to “OFF”.
6. Turn the regulator counterclockwise to set the outlet pressure to zero.
7. Disconnect the air tool or accessory.
8. Pull ring on safety valves (C) Fig.5 & Fig.6, allowing air to bleed from the tanks until tank pressure is approximately 20 psi. Release safety
valve rings.
9. Drain water from air tanks. Turn drain valves (A) Fig. 5 & (B) Fig.6, counterclockwise to open.
WARNING!: WATER WILL CONDENSE IN THE AIR TANKS. IF NOT DRAINED REGULARLY, WATER WILL CORRODE AND WEAKEN THE
AIR TANKS CAUSING A RISK OF AIR TANK RUPTURE.
NOTE: If a drain valve is plugged, pull ring on corresponding safety valve and hold until air pressure has been released. The plugged valve can
then be removed, cleaned, and reinstalled.
10. After the water has been completely drained, turn drain valves to close. The air
compressor can now be stored.
