Unit runs very noisy
Damage to the compressor
Check to make sure the compressor has not been damaged in the
shipping or installation� Make sure the belt guard was not damaged�
Belt guard should not be making contact with flywheel or pulley.
Loose fasteners
Check all bolts and nuts to assure they did not loosen during shipping�
Loose flywheel or pulley
Check to assure pulley and flywheel are correctly tightened�
Improper installation
If unit is left on skid it may cause excessive vibration� Remove unit from
skid and mount loosely to floor with vibration pads and anchor bolts�
Do not tighten bolts tight. Leave nut loose approximately 1/8 inch from
compressor foot�
Oil in discharge air or
out crankcase breather
Break in period
Some oil in the exhaust air is normal during the break-in period and
during heavy usage after the break-in period� Oil discharge should
reduce as hours are accumulated on the unit�
Wrong type of oil
Do not use SAE-30 automotive type oil. Using the wrong oil can cause
problems with the pump and will void the warranty� Only use the oils
that the operating manual recommends (see Lubrication section)�
Improper environment
Unit should not be installed in a poorly vented area or exposed to
extreme cold or hot conditions� Normal operating range should be
between 32°F and 100°F�
Compressor seems to
run hot
Rotation incorrect
Check to make sure the compressor is running the direction of the
flywheel arrow� Air flow should be so that the flywheel directs air across
the head of the pump� Standing in front of the compressor (non-belt
guard side) air should flow back to front�
