7.9 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.

7.9.1 Adjusting the braking force of the drum brake

INFORMATION
After making adjustments, check that activating the manual brake lever creates a sufficient braking effect.
Note that the drum brake must still be able to produce sufficient braking force even when the manual brake lever
is locked into a ratchet position.
To achieve an optimum braking effect, the braking force is adjusted using the adjustment screw (see fig. 25, item
2).
Increase the braking force: Back off the adjusting screw.
•
Reduce the braking force: Screw in the adjustment screw.
•
1) Loosen the counter nut (see fig. 25, item 1) and back off the adjustment screw until a scraping noise can be
heard when the rear wheel is rotated.
2) Screw in the adjustment screw (see fig. 25, item 2) until the scraping noise at the rear wheel disappears and
the wheel runs freely.
3) Tighten the counter nut (see fig. 25, item 1) until the adjustment screw is fixed.
→ The braking force of both rear wheels must be adjusted equally.

INFORMATION
