3.2 Parking brakes
CAUTION!
Risk of pinching or crushing
There may be a very small gap between the rear
wheel and the parking brake with the risk that
you could trap your fingers.
– Keep your fingers away from movable parts
when using the brake, always keep your hand
on the brake lever.
The parking brakes are used to immobilize the wheelchair
when it is stationary to prevent it from rolling away.
WARNING!
Risk of overturning if you brake sharply
If you apply the parking brakes while you are
moving, the direction of movement can become
uncontrollable and the wheelchair may stop
suddenly, which can lead to a collision or to you
falling out.
– Never apply the parking brakes while you are
moving.
The distance between the brake shoe and the tire
can be adjusted. The adjustment must be carried
out by an authorized dealer.

require adjustments.
3.3.4 Folding backrest
IMPORTANT!

Risk of tipping
The hanging of additional load (back pack
or similar items) onto your wheelchair back
posts can affect the rearward stability of your
wheelchair. This can cause the chair to tip
backwards causing injury.

use of anti-tippers (available as an option)
when using your back posts with additional
load (back pack or similar items).

Lift one tire wall away from the rim using a bicycle tire
lever. Do not use sharp objects such as a screwdriver
which could damage the inner tube.
Pull the inner tube out of the tire.
Repair the inner tube using a bicycle repair kit or, if
necessary, replace the tube.
Inflate the tube slightly until it becomes round.
Insert the valve into the valve hole on the rim and place
the tube inside the tire (the tube should lie right round
the tire with no creases).
Lift the tire wall over the edge of the rim. Start close to
the valve and use a bicycle tire lever. When doing this,
check all the way round to ensure that the inner tube is
not trapped between the tire and the rim.
Inflate the tire to the maximum operating pressure.
Check that no air is escaping from the tire.
