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
pulled up, compressor is turned ON. When switch is
pushed down, 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 the ring on the
Safety Valve end to check that it is working properly.
Air Tanks: Two powder coated steel tanks, with a 4
gallon capacity, stores the compressed air until it is
needed.
