Arjo Maxi 500
Arjo · Model Maxi 500
High Friction Solution Dual Controls Adjustable leg chassis Optional scale.
Key tips
- ·Mounting and securement hardware takes real fatigue from vibration and road shock - inspect it as carefully as the device itself.
- ·Post-call battery and function checks catch transport-induced faults that a scheduled PM would miss for months.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Hand control not responding / no powered movement
HighSymptoms: Lift / lower / (Sara/Sabina) seat or leg functions do not respond to the hand control.
Root cause: Discharged or mis-inserted battery, an active emergency stop, an obstruction or overload, or a faulty hand control / cable.
Actuator / drive fault
MediumSymptoms: One movement will not run, runs one direction only, noisy or slow.
Root cause: Worn linear actuator or a limit-switch fault.
Battery will not hold charge
MediumSymptoms: Short run time, frequent low-battery, unit dies mid-transfer.
Root cause: Aged battery pack or a charger / charging-contact fault.
Sling / attachment-point / seat-belt wear
HighSymptoms: Sling loops fraying, sling bar hook worn, seat belt frayed, attachment not secure.
Root cause: Wear - inspect before every use and retire per Hillrom / Arjo guidance.
Caster / brake fault
LowSymptoms: Hard to move, a caster seized, brake will not hold.
Root cause: Debris or a worn caster / brake.

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 the emergency stop is inactivated.
- Reseat the hand-control plug; try the buttons on the unit if fitted.
- If the unit buttons work, replace the hand control; if not, use the emergency lowering and call qualified personnel.
Symptom: One movement will not run
- Test the movement from the control panel to isolate the hand control.
- Check that motion's limit switches and wiring.
- Listen for the actuator motor.
- Replace the actuator if it will not run under command.
- Load-test to the rated limit and confirm all safety stops work.

- RECALL
If the spring pin is not properly reinstalled after maintenance, the pivot bolt could unscrew by itself within a limited period of time, resulting in a hanger bar detachment.
- RECALL
The pivot bolt that attaches the hanger bar to the scale of the patient lift can break, resulting in the hanger bar falling.
