Ref. 1 Air Filter Set - NorthStar 53009 Owner's Manual

6. Regulator: The air coming from the air tank is controlled by the regulator knob. Turn the regulation
knob clockwise to increase discharge pressure, and counter-clockwise to decrease discharge
pressure. Follow tool operating instruction for recommended pressure range.
7. ASME Safety Valve: The valve is designed to prevent system failure 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 anyway. To verify the valve is working properly, pull on the
ring. Air pressure should escape. When the ring is released, it will reseat.
8. Discharge Tube: Carries compressed air form pump to check valve, and then to the storage tank.
It becomes very hot during use and can cause severe burns. Don't touch.
9. Motor Overload: Motor has a protective breaker located on the pump. Excessive amperage draw
will result in the breaker tripping to protect the motor and operator. Reset the breaker by pushing the
black plastic stem back into the housing. Reset switch if it is tripped.
10. Compressor Air Filter: The air filter is designed to clean air coming into pump. To ensure the
pump continuously receives a clean, cool and dry air supply, this filter must always be clean and
ventilation opening free from obstructions.
11. Air Compressor Pump: Oil-free and no need to fill oil.
12. Air Receiver/Storage Tank: 8 gallon.
13. Tank Drain Valve: Used to remove moisture from air after compressor is shut off and air emptied
from tank. Drain moisture daily after each use.
