WARNING: Maintenance hazards
ALWAYS disconnect, lock out and tag the main power supply and then release air pressure from the receiver tank before
cleaning, adjusting, or servicing the compressor. Make sure all guards and shields are replaced before re-starting.
Inspect & drain receiver tank
Inspect safety/relief valves
Inspect/replace air filter
Inspect for air leaks
Dust/debris removal
See detailed instructions for each maintenance item below.
No Modifications. Never modify or alter the
compressor in any way. Modifications can create
serious safety hazards and will void the warranty.
Inspect Safety/Relief Valve
This valve should be inspected and tested on a weekly
basis. The safety valve automatically releases air if the
tank pressure exceeds the preset maximum.
Check the safety/relief valve by pulling the rings.
It is spring loaded and should not be stuck but
come out about ¼" and then snap back into
position when released.
Replace safety/relief valves that do not operate
freely with a valve of the same pressure rating.
WARNING: Safety/Relief valve hazards
If the safety/relief 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 the safety valve operates freely. If the
valve is stuck or does not operate smoothly, it must be
replaced with a valve having the same pressure rating.
Inspect Air Filter
Inspect the compressor's air filter on a weekly basis. A
dirty air filter will not allow the air compressor to operate
at full capacity.
Clean air filter if dirty and restricted air flow.
Replace every 12 months or 1000 hours
(whichever comes first)
Note: Do not operate with the air filter removed.
Keep Compressor Clean
Do not allow air intakes to become blocked. If dust or
debris accumulates in the compressor, clean with a
damp cloth or soft bristle brush.

Note: Do not spray compressor with a garden hose or
pressure washer. Water may enter the compressor
and cause damage to the motor and pump.
Inspect Compressor for Air Leaks
Inspect system for air leaks on a monthly basis. To test:
Squirt soapy water around joints during
compressor operation and watch for bubbles.
Developing bubbles indicate a leak is present.
Tighten fittings, if necessary.
Drain Receiver Tank and Inspect 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 rested receiver
tanks must be replaced.
WARNING: Air tank hazards
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.
IMPORTANT
If a part needs replacement, only use parts that meet
the manufacturer's part number specifications.
Replacement parts that do not meet specifications may
result in a safety hazard or poor operation of the
compressor. Major service, including installation or
replacement of parts, should be made by a qualified
electrical service technician.
