4.8.1 Replacing / Setting a Wheel Lock

Remove the rear wheel. Loosen the clamping screw on the brake profile until you can pull off the
wheel lock to the front (Fig. 102). Replace the wheel lock if required.
To adjust, slide the brake profile back into the clamping element (Fig. 10). Reattach the rear
wheel. The wheel lock should then be remounted such that the distance between the tyre and
brake block is max. 10 mm when the wheel lock is not activated (Fig. 10; subject to technical
changes).
Risk of accident.
CAUTION
proper adjustment. The proper air pressure is indicated on the side wall of the tyre, but should
at least be 7 bar. To ensure sufficient braking effect, use only original rear wheels with an ap-
proved radial excursion of maximally ±1 mm.
Tighten the wheel lock attachment with a torque of 5 Nm.
