CAUTION !
Braking efficiency can be affected by:
•
Incorrect fitting of the brake assembly.
•
Incorrect adjustment of the assembly.
•
Incorrect tyre pressures.
•
Worn tyre treads.
•
Wet tyres.
Wheel Locks
Your wheelchair is equipped with two wheel locks. They
are applied directly against the tyres. To engage, press
both brake levers forward against the stops. To release
the locks, pull the levers back to their original positions.

The wheel locks have not been designed to be used as
brakes for a moving wheelchair. The wheel locks should
therefore never be used to brake a moving wheelchair.
Always use the hand-rims for braking. Make sure that the
gap between the tyres and wheel locks complies with
given specifications. To re-adjust, loosen the screw and
set the appropriate gap. Then re-tighten the screw
(Fig. 4.1 and 4.2).
CAUTION !
After each adjustment of the rear wheels, check the
wheel lock gap and re-adjust if necessary.
Brake Lever Extension
The longer lever helps to minimise the effort needed to set
the wheel locks.
The brake lever extension is screwed to the brakes. By
raising this, it can be flipped forward (Fig. 4.3).
CAUTION !
Mounting the wheel lock too close towards the wheel will
result in a higher effort to operate. This might cause the
brake lever extension to break!
Leaning onto the brake lever extension while transferring
will cause the lever to break! Splashing water from tyres
might cause the wheel lock to malfunction.
CAUTION !
Incorrect mounting of the wheel lock will result in a higher
effort to operate.
This might cause the wheel lock extension lever to break.
Compact Brakes
Compact brakes are underneath the seat sling and are
operated by pulling the brakes towards the rear, in the
direction of the tyre. For the brakes to work properly, this
must be pulled until it reaches the stops, (Fig.4.4).
