Brakes
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 handrims
for braking. Make sure that the interval between the tyres and
wheel locks complies with given specifications. To readjust,
loosen screw and set the appropriate interval. Then re-tighten
the screw, (Fig. 4.3 and 4.4).
CAUTION!
After each adjustment of the rear wheels, check the interval to
the wheel locks and readjust if necessary.
Brake lever extension
The longer lever helps to minimize 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. 4.5).
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 tires 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 Wheel Lock
Compact wheel locks are underneath the seat sling and are
operated by pulling the wheel locks 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. 4.6).
CAUTION!
The mounting bolts for the brakes must not be loosened and/or
re-tightened.

The One-arm Wheel Lock
The one arm wheel lock is underneath the seat sling and is
operated by pulling the brake lever, which is located on the left
or right side, towards the rear, in the direction of the tyre. For
the brakes to work properly, this must be pulled until it reaches
the stop, (Fig. 4.6.1)
Adjustment
To adjust the brake, loose the screws (1) and mount the wheel
lock where it will work in a proper way (Fig. 4.6.2).
CAUTION!
Incorrect mounting of the one arm wheel lock can lead to
serious injury of the user and other people.
