How to Fix / Troubleshooting
Safety first: Keep clear of moving parts. Stop the generator before tightening any fasteners.
- Inspect mounting bolts: Check engine and alternator mounting bolts on the base frame. Tighten to specified torque.
- Check anti-vibration mounts: Look for cracked or collapsed rubber mounts between engine/alternator and base frame. Replace if damaged.
- Verify base frame stability: Ensure the generator base is level and all foundation bolts are tight.
- Observe rotating components: With the set running (by a qualified person), visually check for wobbling pulleys or fans. Shut down and repair any imbalanced parts.
