Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Hand control not responding
- Confirm a charged, correctly inserted battery.
- Clear any obstruction and check the load is within the rated limit.
- Confirm all emergency stops are inactivated.
- Reseat the hand-control plug; try the control-panel buttons if fitted.
