SECTION 6

TROUBLESHOOTING

Trouble

Probable Cause

Low discharge pressure

•Restricted inlet

•Defective compressor valves

•Leaks in the compressed air distribution system at fittings, connections,

etc.

•Pressure switch defective or set wrong

•Drive belt slipping

•Incorrect speed

•Worn piston rings or loose piston

•Faulty hydraulic unloader

•Leaking head gasket

•Low lubricant pressure

•Drain valve open

•Defective pressure gauge

•Excessive running clearances

•Pressure relief valve leaking

•Clogged intercooler

•Loose compressor valves or leaking at valve gaskets

•Compressor incorrectly sized for the alti tude at which it is operating

Water in the crankcase

•Compressor does not run long enough to get hot and vaporize the liquids

(lubricant appears milky)

squeezed out of the air during compression

(compressor may be too large

for application)

•Incorrect or inferior grade of lubricant

•System pressure leaking back through dis charge valve

Rusty valves

•Compressor operated too infrequently

and/or cylin ders

•Compressor does not run long enough to get hot and vaporize the liquids

squeezed out of the air during compression

(compressor may be too large

for application)

•Compressor not properly prepared for stor age

•Discharge line from compressor head is pointed upward allowing con -

densation to drain back at shutdown

Excessive vibration

•Incorrect speed

•Compressor valves not functioning prop erly

•Loose pulley/sheave

•Motor or engine out of balance

•Compressor, motor or engine not secured tightly, or tightened into a

bind

•Foundation or frame inadequate
