A. MAINTENANCE
You should check the items on this chart at the indicated intervals. If any of the items
are loose, worn, bent or distorted, immediately have them checked and/or repaired by
your authorized Sunrise supplier. Frequent maintenance and servicing will improve per-
formance and extend wheelchair life.
NOTE– Check weekly, and use a clean, dry cloth or compressed air as needed to keep
glide bearings free of debris.
B. TROUBLESHOOTING TIPS
If you should notice your C.G. Tilt system binding up, not running in a smooth fash-
ion, or emitting an unusual noise during use, a foreign matter may have come into
contact with the glide bearings. If this occurs, use a clean, dry cloth or compressed air
to clear or, if needed, please see your authorized Sunrise supplier.
If your tilt system will not function, check to ensure the tilt lock-out sensor is seated
properly in its mount. The wires should lead out of the sensor toward the front of the
chair.
