operating the knee walker
The Drive 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.
· This is a medical device, not a toy. Do not allow children
or adults to use this as a toy or for entertainment.
· Always check the fasteners on the tiller, wheels, brakes,
and seat for tightness before use.
