Anti-tippers/Wheel Locks

Part No. 1110558

Invacare® Tracer IV®Heavy Duty/Extra Wide Wheelchair

10 Anti-tippers/Wheel Locks

10.1

Installing/Adjusting Anti-tippers

WARNING

After any adjustments, repair or service and before use, make sure all attaching hardware is tightened securely. Otherwise

injury or damage may occur.

WARNING

Anti-tippers are specific to the different seat-to-floor angles and/or seat-to-floor heights. Refer to the chart in this section of

the manual for correct usage and adjustment. If these requirements cannot be achieved, DO NOT use the wheelchair.

Contact a qualified technician. Any changes to the seat-to-floor angle or seat-to-floor height may require different

anti-tippers.

If so equipped, anti-tippers MUST be attached at all times. Inasmuch as the anti-tippers are an option for this wheelchair

(You may order with or without the anti-tippers), Invacare strongly recommends ordering the anti-tippers as a safeguard

for the wheelchair user.

Anti-tippers MUST be fully engaged and release buttons fully protruding out of adjustment holes.

ALWAYS use anti-tippers. When outdoors on wet, soft ground or on gravel surfaces, anti tippers may not provide the

same level of protection against tipover. Extra caution MUST be observed when traversing such surfaces.

Ensure both anti-tippers are adjusted to the same mounting hole.
