BRAKE TE SIO ADJUSTME T
The tightness can be adjusted with the nuts at either end of
the brake cable. When adjusting the brake from the brake
handle, both sides of the handles should be adjusted to the
same tension because they operate the same drum pad.
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 squeezed position, the
brake wheel does not turn but is not too tight.

- 21 -
1. Before mounting the knee scooter, ensure the hand
brakes are fully engaged, to prevent it from rolling. Find
support with your hands holding on to the handle bars and
stand with your uninjured leg, Grab onto both the handlebars
before you "step-on' your knee walker. Doing so assures
that the model is stable and provides you with something to
hold securely.
2. While still grabbing onto the handlebars, mount your
injured leg to the knee rest - while keeping your uninjured
leg on the ground beside the knee walker. You should be
standing with your posture upright and comfortably on your
good leg. You should not be hunched over the unit, but in
your normal, upright posture. Any issue regarding adjustment
can be found at the Adjustment section of this manual.
3. Once balanced, disengage the hand brakes and use your
good 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.
4. Slow down when navigating tight corner or turning. When
turning on the same side as your propeling leg, it is common
to hit the rear wheel if not careful. Slow down and extend a
wider stride movement until the turn is made. When doing a
U-turn in a narrow space, always slowdown and be aware
of your surrounding. Follow the three point turn technique
(forward, back, forward) same function as a normal scooter
or driving a car.
5. To dismount the knee walker. Bring the knee walker to a
even surface, ensure the hand brakes are fully engaged to
prevent it from rolling. With your hand holding on to a support,
stand up on the good leg and carefully swing your injured
leg over the knee pad.
