A visual inspection of the automatic lubrication system and components is the first step in diagnosing a problem. Stop the engine. Lower the bucket to the ground. Make the following inspections:
- Inspect the injector banks and all of the lubrication lines for lubrication leaks.
- Inspect all of the air lines and all of the connections for damage and for leaks.
- Inspect the electrical system for worn wiring or frayed wiring. Also, inspect the electrical system for damaged connectors or a bad fuse.
