Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor won't start | Power issue, pressure switch fault, thermal overload tripped | Check power supply, reset thermal overload, check pressure switch |
| Low pressure output | Leaks in system, worn piston rings, faulty pressure regulator | Check for air leaks, inspect piston rings, adjust/replace regulator |
| Excessive noise/vibration | Loose components, worn bearings, improper mounting | Tighten all fasteners, check bearings, ensure proper installation |
| Oil in air lines | Overfilled oil, worn piston rings, incorrect oil type | Check oil level, replace piston rings, use recommended oil |
| Motor overheats | Dirty cooling fins, low voltage, excessive cycling | Clean cooling fins, check voltage supply, allow proper cool down |
| Slow recovery time | Worn valves, leaking check valve, restricted intake | Inspect and replace valves, clean air filter, check intake |
Maintenance Schedule
- Daily: Drain moisture from tank, check oil level
- Weekly: Inspect for leaks, clean air filter
- Monthly: Check belt tension (if applicable), inspect hoses
- Every 3 Months: Change oil, inspect valves
- Annually: Replace air filter, complete system inspection
- Every 2 Years: Replace safety valve, thorough maintenance check
