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: Power height will not run
- Confirm mains power and any fuse.
- Operate the foot control and listen for the actuator.
- Check the limit switches.
- Substitute a known-good foot control.
- Replace the actuator if power reaches it but it will not run, then load-test to 600 lb capacity.
Symptom: Backrest will not hold
- Note how fast it drops.
- Inspect the gas spring.
- Replace the gas spring.
- Confirm the backrest holds through its range.
- Check the pivot hardware is tight.
