Daily:
CHECK THE OIL LEVEL.
Oil should be half up, or at the bottom of the threads on
the fill spout, or 1/2 full in the sight glass.
DRAIN THE TANK.
Turn off the power to the compressor and drain all the
moisture from the bottom of the tank.
Weekly:
CHECK THE OIL.
If the oil appears contaminated by moisture or dirt,
change immediately.
CHECK THE BELTS.
Turn off the compressor and inspect the belts for
damage, excessive wear, and correct tension. Replace if
necessary.
TEST THE SAFETY VALVE.
Pull the ring on the safety valve. Air should escape
and then reset. In the event the compressor ran over
pressure, the safety valve would reduce the tank
pressure to a safe level. Never run the unit without this
safety valve or attempt to adjust it.
GENERAL INSPECTION.
Check the overall operation of the unit. Tighten any
loosen bolts, inspect for air leaks and inspect for any
unusual noises or vibrations.
INSPECT COMPRESSOR INTAKE.
NEVER use gasoline, thinners or other flammable
solutions to clean valves or related parts. Check to
be sure the valves are seated against the sealing
surface around each port. If the valves are not sealing,
compressor capacity will be severely reduced.
Maintenance Procedures Review
SAFETY PROCEDURES.
Adherence to safe working procedures are important to Service personnel at the time of servicing and to those who
may, at a later date be around the compressor and the system it serves. Routine maintenance insures trouble free
operation and protects your investment. All warranties are void if maintenance is neglected.
