Possible Cause(s)
1. Damage to the compressor
2. Loose fasteners
3. Loose flywheel or pulley
4. Improper installation
1. Break in period
2. Wrong type of oil
3. Improper environment
Rotation incorrect
Corrective Action
1. 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
2. Check all bolts and nuts to assure they did not loosen
during shipping
3. Check to assure pulley and flywheel are correctly tightened
4. 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
1. 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
2. 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)
3. 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
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
