Operation
1. When mounting/dismounting, always make sure
the brakes are engaged. You should stand naturally
with your injured leg supported on the knee rest at a
90-degree angle..
2. Your hips should be even, and your uninjured foot
placed flat on the floor. The handlebars should be set
at a comfortable distance in front of your body, normally
about waist height. You should not be hunched over
the unit, but in your normal, upright posture.
3. Before mounting the knee walker, ensure the hand
brakes are fully engaged, to prevent it from rolling,
then with both hands firmly on the handlebars, mount
the knee scooter from one side and place the knee
of your injured leg on the knee rest.
4. Once balanced, disengage the hand brakes and
use your other leg to propel you (much like a child’s
scooter). Go slowly to start and progress up to a normal
walking speed. Use your best judgement and be
cautious on inclines and uneven sidewalks.

Brake Adjustment The tightness can be adjusted with the
nuts at either end of the brake cable. Turning the screw
clockwise will loosen the brake and turning the screw
counter clockwise will tighten it. The pressure of the brake
mechanism on the brake
wheel should be enough so
that, when the hand lever is in
the fully squeeze position, the
brake wheel does not turn but
is not too tight.
Braking The brake is engaged by holding the brake lever
on the handlebar. The braking wheel must be in contact with
the floor and the brake works best with weight on the
knee walker. Set
the brake -squeeze the brake lever and on
the brake lever holder.
To unlock the brake
-squeeze the
brake lever.

Maintenance
With routine use, nuts and bolts on the
steering column, knee platform, can
become loose. To ensure safe continuous
operation of the Smooth knee walker, it is
important to periodically inspect the product
for loose nuts and bolts and re-tighten as
appropriate.
Always test the brakes by both walking
and squeezing the brakes and by stopping,
pushing down on the brakes to a locked
position, and then trying to push the knee
walker. If the brakes do not lock the
wheels, the brakes need to be adjusted. If
adjustment does not tighten the brakes,
DO NOT use the knee walker.
Use soapy water and a soft cloth to
clean the surface of the walker. Wipe off
any moisture after cleaning. Using abra-
sive clothes or other products can cause
grates.
