Likely Solutions
1. Drain oil and refill to proper level with recommended oil.
2. Move compressor to a warmer location.
Check that recommended oil is in crankcase.
3. Reduce air pressure, then check all fittings with
a soap solution for air leaks and tighten as needed.
Do not overtighten.
1. Check inlet and outlet filters.
Clean and/or replace as needed.
2. Check if accessory CFM is met by Compressor.
If Compressor cannot supply enough air flow (CFM),
you need a larger Compressor.
3. Reduce air pressure, then check all fittings with
a soap solution for air leaks and tighten as needed.
Do not overtighten.
4. Replace with wider hose and/or hose connections.
5. Drain oil and refill to proper level with recommended oil.
6. Higher altitudes require compressors with greater output.
1. Check inlet and outlet filters.
Clean and/or replace as needed.
2. Drain oil and refill to proper level with recommended oil.
3. Add oil to proper level, check for leaks.
4. Clean and/or replace filters more often or
move unit to cleaner environment.
5. Reposition unit on a level surface.
1. Reduce air pressure, then check all fittings with a soap
solution for air leaks and tighten as needed.
Do not overtighten.
2. Replace belt guard.
3. Drain oil and refill to proper level with recommended oil.
4. Add oil to proper level, check for leaks.
5. Reposition unit on a level surface.
Install inline air filter/dryer, and/or relocate
to less humid environment.
Reduce air pressure, then check all fittings with a soap
solution for air leaks and tighten as needed.
Do not overtighten.
1. Drain oil and refill to proper level with recommended oil.
2. Reposition unit on a level surface.
3. Clean Crankcase vent.
