Operating the knee walker
The Knee Walker is a mobility device that provides strength and comfort to
anyone who may have an injury below the knee. It allows an even distribution
of body weight by supporting half of the weight on the device and the other
half on the non-injured leg. The device has a cushioned platform to support
both the injured leg and ankle to make certain that no weight will be placed
on the lower leg.
The device is designed for easy steering and stopping. Brakes are also
featured on this device for controlled movement and safety.
- Placement of injured leg on pad should be centered side to side and positioned forward to cover the full length of pad.
- With injured leg on pad, stand as straight as possible (adjust the height of the Knee Walker as necessary).
- With injured foot pointing down, the propulsion leg should be maintained as close as possible to the pad.
- While on your toes, start out with small steps with propulsion leg. Concentrate on keeping that leg next to the pad. With practice, you should be able to move forward without deviating to the opposite side.
Assembly instructions
- Straighten the tiller to the upright position. Slide locking mechanism to the side to allow tiller to reach full upright position. Release locking mechanism to lock tiller in position.
- Slide the locking mechanism into a groove on the tiller, and depress the locking handle to secure the tiller lock.
- Insert pad post into the receptacle on the frame. Secure the pad in place by inserting a hexagonal screw into the hole and tighten with the star-shaped rotary knob.
- Attach basket by sliding basket receptacles down over hooks on the front of the tiller.

feature.

Additional cautions
Always consult with your health care practitioner or authorized dealer on the proper fitment and usage of your MOBB Knee Walker. The instructions here are a guide and should be used in conjunction with professional assistance.
- The MOBB Knee Walker is designed to replace the use of crutches for long-term lower limb injury recovery. It should be used at slow and controlled speeds. If not, tipping can occur with too much speed while turning. While becoming accustomed to its operation in the learning phase, apply the brake cautiously when starting, stopping, and turning.
- Always check the fasteners on the tiller, wheels, brakes, and pad for tightness before use.
- Do not sit, stand or lean on the steering mechanism.
