10 Hand Carry Electric Air Compressor Manual
OIL DIPSTICK: The dipstick will register the amount of oil in the pump. Oil
level should be checked on a daily basis to ensure it does not exceed the
maximum notch or fall below the minimum notch on the dipstick. If low, add
SAE 30W non-detergent oil.
PUMP OIL DRAIN: The removal of the drain plug will allow the air compres-
sor lubricants to be changed. To remove drain plug, turn counterclockwise
and pull.
AIR TANK DRAIN VALVE: The drain valve is used to remove moisture from
the air tank(s) after the air compressor is shut off. NEVER attempt to open
the drain valve when more than 10 PSI of air pressure is in the air tank!
To open the drain valve, turn the knob counterclockwise. Keep the air com-
pressor in such a position that all condensation will flow out.
AIR COMPRESSOR PUMP: To compress air, the piston moves up and down
in the cylinder. On the downstroke, air is drawn in through the air intake valve
while the exhaust valve remains closed. On the upstroke, air is compressed,
the intake valve closes and compressed air is forced out through the exhaust
valve, into the discharge line, through the check valve and into the air tank.
EXPLODED VIEW & EXPLANATION OF AIR COMPRESSOR FEATURES
EASY START VALVE: The oil lube models have this feature. This valve re-
lieves a portion of the compressed air which allows the motor to start easier.
The valve automatically closes at a preset pressure which allows a full volume
of compressed air to go into the air tank.
It is recommended these air compressors not be operated at more than a 50%
duty cycle. This means an air compressor that pumps air longer than 50% of
one hour is considered misuse. Maximum air compressor pumping time per
hour is 30 minutes.
SAFETY RELIEF VALVE: This valve is designed to prevent system failures
by relieving pressure from the system when the compressed air reaches a
predetermined level. The valve is preset by the manufacturer and must not be
modified in any way. To verify the valve is working properly, pull on the ring.
Air pressure should escape. When the ring is released, it will reset.
