OPERATION CONTROLS

AIR COMPRESSOR PUMP. To compress air, the piston moves up and down in the cylinder. On the

downstroke, air is drawn in through the intake valves. The exhaust valves remain closed. On the

upstroke of the piston, air is compressed. The intake valves close and compressed air is forced out

through the exhaust valves.

CHECK VALVE (A) FIG.3. 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.

ON/AUTO OFF SWITCH (A) FIG.5. Turn this switch ON by lowering lever downwards to provide

power to the automatic pressure switch and lift to turn compressor OFF.

PRESSURE SWITCH (C) FIG.5. 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.6. The air pressure coming from the air tank 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

adjusted while operating the accessory.

OUTLET PRESSURE GAUGE ( C) FIG.6. The 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 GAUGE (A) FIG. 6.The tank pressure gauge indicates the reserve air pressure in the

tank.

COOLING SYSTEM. This compressor contains an advanced design cooling system. The cooling

system works when air is being expelled.

DRAIN VALVE (A) FIG. 4. The drain valve is located at the base of the air tank and is used to drain

condensation from the tank to prevent corrosion. Drain tank at the end of each use.

MOTOR THERMAL OVERLOAD PROTECTOR (RESET (B) FIG. 3). 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 (B).

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 VALVE (B) FIG. 5. If the pressure switch does not shut off the air compressor at its

“Cut-Out” pressure setting, the safety valve will protect against high pressure by “popping out” at it’s

factory set pressure (slightly higher than the pressure switch “Cut-Out” setting).

WARNING!: If the safety valve does not work properly, over pressurization may occur, causing air

tank rupture or an explosion. Daily, pull the ring on the safety valve to make sure that the safety

valve operates freely . If the valve is stuck or does not operate smoothly, it must be replaced with the

same type of valve before operating again.

the pressure less than 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
