OIL DIPSTICK: The dipstick will indicate 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.
AIR TANK DRAIN VALVE: The drain valve is used to remove moisture from the
air tank 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 compressor in such a
position that all water 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, the intake valve closes, air
is compressed and forced out through the exhaust valve, into the discharge line,
through the tank check valve and into the air tank.
AIR COMPRESSOR FEATURES
TANK CHECK VALVE: This valve prevents the compressed air in the tank from
re-entering the pump discharge line.
EASY START VALVE: This valve relieves a portion of the compressed air which
allows the motor to start easier. The valve automatically closes at a preset pressure
which allows the full volume of compressed air to go into the air tank.
It is recommended this air compressor 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 predeter-
mined 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 reseat.
PUMP OIL DRAIN: The removal of the drain plug will allow the air compressor
lubricants to be changed. To remove drain plug, turn counterclockwise.
