KNOW YOUR COMPRESSOR

Handle: Convenient, rubber gripped handle allows

for easy transport of your air compressor.

Air Regulator: The air regulator controls the air

flow pressure. Turn regulator clockwise to increase

air pressure, counter-clockwise to decrease air

pressure.

Air Chuck: Convenient quick disconnect air chuck

allows for fast, easy connection to an air hose.

Tank Drain Valve: The Tank Drain Valve can be

opened to allow moisture and compressed air to be

released from the Air Tank.

WARNING! Tank Drain Valve should always be

opened slowly to avoid damage to equipment and

possible injury.

Air Filter: This heavy duty metal air filter keeps

your compressor running cleanly, by filtering out

impurities.

Oil Breather Cap: As the compressor motor

operates pressurized air must be released from the

crank case. The oil breather cap allows built up air

to escape, while shielding your air compressor from

airborne impurities.

Power Switch: The red tipped power switch turns the

air compressor on and off. When switch is in horizontal

position, compressor is turned ON. When switch is in

vertical position, compressor is turned OFF.

Note: Always make sure that compressor Power

Switch is in the OFF position before

performing any maintenance or plugging the

compressor into a power supply.

Pressure Gauges: These dual gauges indicate the

amount of air pressure built up in the air tank, as

well as the air pressure being delivered to the air

chuck.

Safety Valve: The Safety Valve device relieves

pressure from the Air Tank in the event of excessive

pressure build up. The Safety Valve is preset at

factory. Do not attempt to make any adjustments to

the Safety Valve. Periodically pull ring on the Safety

Valve end to check that it is working properly.

Air Tank: Powder coated steel tank, with a 4 gallon

capacity, stores the compressed air until it is needed.

CRANKCASE AS DESCRIBED BELOW:

1. Place compressor on level ground.

2. Remove the Oil Shipping Plug from the Oil Fill

hole, located on the top of the crankcase cover

at the rear of the air compressor.

3. Slowly pour the oil into the Oil Fill hole, until the

oil level rises to the center of the red dot on the

Oil Sight Glass.

Note: This compressor uses only SAE 5W-30 

motor oil.

4. Install the Oil Breather Cap into the Oil Fill hole.

Firmly hand tighten the Oil Breather Cap by
