
Always disconnect, lock out, and tag the main power supply and then release air pressure from
the air tank before cleaning, adjusting, or servicing the compressor. Make sure all guards and
shields are replaced before re-starting.
Maintain the product by adopting a program of conscientious repair and maintenance in accordance
with the following recommended procedures. It is recommended that the general condition of any tool
be examined before it is used. Keep your tool in good repair. Keep all cutting tools sharp and clean.
Keep handles dry, clean, and free from oil and grease. The following chart is based on a normal
operation schedule.

No Modifications. Never modify or alter the compressor in any way. Modifications can create serious
safety hazards and will void the warranty.
Inspect and Drain Receiver Tank. Drain water from the receiver tank daily. Water left in the tank can
cause the tank to weaken and corrode, increasing the risk of tank rupture. Badly rusted receiver tanks
must be replaced.

Failure to replace a rusted air receiver tank will eventually result in tank rupture or explosion,
which could cause substantial property damage, severe personal injury, or death. Never modify or
repair a tank. Obtain replacement from service center.
Inspect Safety Valve. This valve should be inspected and tested on a weekly basis.

Check the safety valve by pulling the rings. It is spring loaded and should not be stuck but
come out about 1/4" and then snap back into position when released.

Replace safety valves that do not operate freely with a valve of the same pressure rating.

If the safety valve does not work properly, over-pressurization may occur causing air tank rupture
or explosion. Occasionally pull the ring on the safety valve to make sure it operates freely.
