2.5. Brakes

2.5.1 Manual brakes

The manual brakes (photo 18) are designed to secure the
wheelchair during long stops. They are not intended to slow
down the wheelchair or to be used as support during a
transfer. They must be operated simultaneously.
In order to brake, push the handle (A) forward.The handle
folds back to facilitate transfers. Draw as a preliminary the
handle upwards ! Once the brakes are engaged, the wheelchair
should not move at all.
Note : brake adjustments are based upon the diameter and
type of the wheels. After repairing a flat tyre or in the event
of wear of the pneumatic or solid tyre, you may need to adjust
the brake(s). To adjust the brake(s), loosen the two screws
(B) and slide the brake assembly to obtain the following value
between the wheel and the brake shoe in unlocked position
