Varian Medical Systems · Model VariSource iX HDR afterloader
Force feedback mechanism device helps ensure highest possible treatment success ratio. Smallest source in the industry (0.59mm dia. x 5mm long) permits use of needles as thin as 20 gauge and virtually eliminates catheter kinking. Ergonomically designed indexer enables precise connection of catheters to the afterloader. Internal CamScale system delivers accurate confirmation of wire position accuracy. Multiple safety & backup features (e.g., on-board radiation detector and emergency retract system).

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: Hydraulic height / Trendelenburg will not lift or holds poorly
- 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 / steer castor will not hold / 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 and the steer-lock engages.
- Check all four corners brake evenly.
Symptom: Backrest / Fowler will not raise or hold
- Check the gas spring / strut and the release mechanism.
- Confirm the pneumatic assist (where fitted) holds.
- Replace a weak gas strut.
- Confirm the backrest holds at several angles under load.
- Inspect the pivot hardware for wear.
Symptom: Siderails / IV pole / accessories loose or will not latch
- Inspect the latches, detents and accessory sockets for wear.
- Adjust or replace worn latch hardware.
- Confirm the siderails lock up and drop cleanly.
- Check the IV pole and litter attachments are secure.
- Load-test any patient-support accessory.
