6.0 Brakes

CAUTION!
Braking power can be affected by incorrect fitting and
adjustment of the brakes, as well as tyre pressure which is too
low.
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.
Braking power will decrease with:
• Worn tyre tread
• Tyre pressure that is too low
• Wet tyres
• Improperly adjusted wheel locks.
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. 6.1).
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. 6.1).
WARNING !
• 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.
Drum Brakes
Drum brakes permit safe and convenient braking for an atten-
dant. They can also be set with the aid of the locking levers (1)
to prevent rolling. These levers must snap audibly into place.
Drum brakes do not depend on the aid of air pressure inside the
tires. Your wheelchair cannot be moved when the drum brakes
are set, (Fig.6.2).
