5.4 Adjusting the wheel locks
The wheel locks are adjusted correctly during manufacture and should not require further
adjustment. Over time of use, however, it may be required to re-adjust the wheel locks to
ensure proper function. In any case, if you feel that the locks are not tight enough, adjust
them immediately as follows.
Open the locks entirely by pulling the lever backwards as far as possible. Loosen the screws
(1) on the top of the rail (2). Slide the lock in its rail forward (to loosen the lock) or
backwards (to tighten the lock). Make sure that the lever remains upright. Tighten the
screws.
The optimum distance (factory setting) between the brake shoe and the tire depends on the
type of wheel locks installed on your model and is 10-12 mm/0.4-0.45 inch (3) or 23-25
mm/0.9-1.0 inch (4).
