C o d e Possible Cause
Possible Solution
1
Clogged or dirty inlet and/or discharge line filter.
Clean or replace
2
Lubricant Viscosity too low
Drain existing lubricant and refill with D
E
WA LT Synthetic lubricant
3
Air leaks in air discharge piping
Check tubing and connections
4
Lubricant viscosity too high
Drain existing lubricant and refill with D
E
WA LT Synthetic lubricant
5
Lubricant level too low
Add lubricant to crankcase to proper level. Check for bearing damage.
6
Detergent type lubricant being used
Drain existing lubricant and refill with D
E
WA LT Synthetic lubricant
7
Extremely light duty cycles.
Run unit for longer duty cycles
8
Compressor check valve leaky, broken, carbonized or loose
Inspect valves.Clean or replace as required.
9
Carbon build up on top of compressor pump piston
Clean piston. Repair or replace as required.
1 0
Compressor pump piston rings damaged or worn (broken, rough, Install new rings
or scratched). Excessive end gap or side clearance. Piston rings
not seated, are stuck in grooves or end gaps not staggered.
11
Compressor pump cylinder or piston scratched, worn, or scored. Repair or replace as required
1 2
Compressor pump connecting rod, piston pin, or crankpin bearings worn or scored
Inspect all. Repair or replace as required.
1 3
Compressor pump crankshaft seal worn or crankshaft scored
Replace seal or crankshaft assembly
1 4
Extremely dusty atmosphere
Install more effective filtration or relocate unit
1 5
Ambient temperature too low
Relocate unit to warmer environment. Ensure D
E
WA LT synthetic oil
is in crankcase.
1 6
Compressor pump worn cylinder finish
Degalze cylinder with 180 grit flex-hone
1 7
Air compressor is not large enough for air required
Check the accessory air requirement. If it is higher than the CFM or
pressure supply of the air compressor, you need a larger air
c o m p r e s s o r.
1 8
Possible defective safety/relief valve
Operate safety relief valve manually by pulling on test ring. If it still
leaks, replace.
1 9
Excessive air tank pressure
Adjust pilot valve. If problem still exists replace pilot valve.
