PROBLEM POSSIBLE CAUSE
Abnormal piston, ring or 1 Lubricant viscosity too tow
cylinder wear 2 Lubricant level too law
3 Detergent type lubricant being used
4 Cylinder(s) or piston(s) scratched, worn or scored
5 Extremely dusty atmosphere
6 Worn cylinder finish
Air delivery drops off
U_it does not come up to
speed
Unit ts slow Io come up to
speed
Unit runs excessively hot
Excessive noise durtng
operation
Excessive starting and
stepping
High ellconsumption
1 Ctogged or dirty inlet and/or discharge line fitter
2 Atr leaks tn air discharge piping
3 Lubricant viscosity too high
4 Compressor valves leaky, broken, carbonized or Ioose.
5 Piston rings damaged or worn (broken. rough or scratched)
Excessive end gap or side clearance
6 Piston rings not seated, are stuck In grooves or end gaps not
staggered,
7 Cylinder(s) or piston(s) scratched_ worn or scored
8. Defective safety/relief vatve.
1 Loose beltwheel or motor pulfey, excessive end play in
motor shaft or loose drive belts
2. Lubricant viscosity tea high
3 Improper line voltage
4 Compressor valves leaky, broken, carbonized or loose
S, Defective bait bearings on crankshaft or motor shaft
1 Lubricant vtscosttytoo high
2, Leaking check valve or check valve seat blown out
3, Ambient temperature too low

3, Compressor valves leaky, broken, carbonized or loose
4, Wrong beltwheel direction of rotation
1, Loose beltwheel or motor pulley, excessive and play In
meter shaft or loose drive belts
2, Lubricant viscosity too high
3, Lubricant level too few
4 Compressor valves leaky, broken, carbonized or loose
5, Carbon build-up on top of piston(s)
6, Defective ball bearings on crankshaft or motor shaft
.7 Leaking check valve or check valve seat blown out
t Air leaks te ai_r discharge piping
2 Pressure switch differential too narrow
3 Leaking check valve or check valve seat blown out
4 Excessive condensate tn receiver tank
t Clogged or dirty inlet and/or discharge llne triter
2 Lubricant viscosity toolow

Excessive end gap or side clearance
5 Pislon rings not seated, are stuck tn grooves or end gaps not
staggered
6 Cylinder(s) or piston(s) scratched, worn or scored
7 Connecting red, piston pin or crankpin bearings worn or
scored
B Crankshaft seat worn or crankshaft scored
9 Worn eytinderftnish
