Key tips
- ·Casters and the wheel-lock brake take the most day-to-day wear - check both every PM, not just on complaint.
- ·A cracked weld or loose frame joint is a safety-critical finding - pull the unit from service until it's repaired.
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.
Hydraulic height / Trendelenburg will not lift or holds poorly
HighSymptoms: Pump will not raise the deck, or the deck settles under load.
Root cause: Worn hydraulic pump / seals, an internal valve leak, or low hydraulic fluid.
Brake / steer castor fault
MediumSymptoms: Brake will not hold, fifth-wheel steer ineffective, castor shimmy.
Root cause: Worn brake linkage, castors, or the fifth-wheel mechanism.
Backrest / Fowler mechanism fault
MediumSymptoms: Backrest will not raise / hold, gas strut weak, pneumatic assist failed.
Root cause: Worn gas spring / strut or the release mechanism.
Siderail / IV pole / accessory fault
LowSymptoms: Siderails will not latch or drop, IV pole loose, litter attachments worn.
Root cause: Worn latches, detents, or accessory sockets.
Powered drive fault (powered stretchers)
MediumSymptoms: Drive assist will not engage or is weak, drive-fault code.
Root cause: Drive battery, motor / controller, or the throttle.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Caster / wheel and brake function check
- ·Frame, weld, and mounting-hardware inspection
- ·Upholstery / surface condition check
- ·Annual full PM
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: Will not lift or settles under load
- Check the hydraulic fluid level.
- Pump the deck up under load and time how fast it settles.
- Inspect the pump and cylinder for external leaks.
- Rebuild the pump with the seal kit or bleed the system per the manual.
- Confirm it holds at full height under the rated load.
Symptom: Brake will not hold or castor shimmy
- Inspect the brake linkage and each castor.
- Adjust the central-brake linkage.
- Replace worn castors and the fifth-wheel components.
- Confirm the brake holds on an incline.
- Check steer-lock engagement.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Paramed Corporation (d/b/a, Descent Control Systems), a manufacturer and distributor of patient transport devices, merged with an affiliate of Stryker Corporation in August 2009. As part of the due diligence process, Paramed's powered Mobility Offers Versatility (MV) chair was reviewed to identify potential compliance issues in relation to product documentation and classification.
- RECALL
Some of the red release bars used during the time frame of 22 December 2010 through 31 January 2011 were reworked. The rework subjected the parts to excessive heat and as a result, the bars can bend during the action of squeezing the release bar against the black cross tube to release the track. The red release bars may bend to the degree that they permanently engage the track locking mechanism
