7.5 Adjusting the wheel locks

WARNING
Failure to verify brake functionality
Accident, user falls due to incorrect adjustment and improperly inflated tyres
► Check the correct spacing between the wheel lock bolt and tyre (see the following section for details).
► Check the correct position of the wheel lock bolt relative to the tyre. During braking, the wheel lock bolt has to
cover at least half the tyre width.
► Always carry out adjustments to the wheel lock on both sides.
► Ensure that the user can operate the wheel lock without great effort. The force required to do so must not
exceed 60 N.
► Check the tyre pressure of the drive wheels. Note the information in the section "Technical data" or on the tyre
sidewall.
► Only use original drive wheels with a verified maximum radial out-of-round of 1 mm.
This adjustment must be made for fine adjustment of the wheel lock.
