Wheel locks
Scissor wheel locks are shown in
Fig. 21a. The wheel locks mount on
clamping systems (1) and are
correctly set prior to leaving the
factory. To apply the wheel lock pull
the operating lever (2) forwards until
you feel it go over centre, and the
grip arm (3) grips the tyre (4). Scissor
locks can also be mounted on the
lower frame tube (Fig. 21b).
Warning:
Wheel locks are not brakes they
are not designed to slow down the
chair when it is moving. Wheel
locks, when properly adjusted,
prevent the rear wheels from
turning when the chair is stationary.
Knee brake
Operating position and adjustment
instructions for the kneebrake
wheel lock are shown in Fig. 21.
Slaken the two screws (1) on the
wheel lock clamp and slide the
brake to achieve the correct wheel
lock gap, then retighten.
The wheel lock gap (2) (which is
the gap between the nearest point
of the wheel lock and the tyre)
should be 3mm with pneumatic
tyres (tyres filled with air) and 5mm
with solid tyres, when the wheel
lock is in the released position.
