2.5. Brakes

2.5.1 Manual brakes

The manual brakes (photos 18 & 19) 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
(photo 18)
Please make sure this adjustment is always done as des-
cribe whatever the chair configuration is.
Solid tyre X = 4 mm, Pneumatic tyre X = 5 mm

Keep your fingers away from movable parts to prevent injuries !
2.5.2 Hub brakes (photos 20 & 21)
Besides the functions provided by manual brakes, the hub
brakes provide the slow down (for example, on a slope) and
improved safety because they are still efficient when you have
a flat tyre !
To slow down, gradually pull the lever (A) upwards.
To lock the brake in parking position, with the lever (A)
tightened, push the lock (B) to engage it in the notches of the
brake handle ; then pull the lock up to unlock.
To adjust braking : turn the screw (C) counterclockwise to
increase braking force and turn clockwise to reduce it.
The specific adjustments of hub brakes must always be per-
formed by your Dealer.
Always operate the two brakes simultaneously and do
not take slopes exceeding 5° to ensure perfect control of the
wheelchair steering !
