Stryker · Model 660 Atlas
Big Wheel. Four Corner IV Receptacles. Glideaway Siderails. Rubber Bumpers. Pop-up Push Handles. Three-sided foot control hydraulics. Hands-free Trendelenburg. Integrated patient transfer boards. Unilower Pedal.
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
The heated tube sets were consistently leaking and detaching from the cassette.
- RECALL
The retractable cord stretchers were fitted with power cords, manufactured by Electri-Cord, whose prongs have the potential to fracture inside the molded section of the plug, causing melting and charring.
- RECALL
The brake cams may crack or develop excessive wear, resulting in the brakes not locking the wheels, or the stretcher not being locked firmly in position.
