7.4.1 Adjusting the knee lever wheel locks
1) Loosen the hexagon socket screws on the tube clamp (see fig. 21, item 1).
2) Adjust the knee lever wheel lock by sliding it (see fig. 21, item 2). When the wheel lock is disengaged, the clear
distance between the tyre and wheel lock bolt must not exceed 5 mm (see fig. 22).
→ The distance between the wheel lock bolt and the drive wheel may be 1 – 5 mm when the wheel lock is not
engaged.
→ It must be possible to operate the brake evenly and easily on both sides.
→ The wheel lock bolt must lock the drive wheel securely when stationary.
3) Alternately tighten the hexagon socket screws to 15 Nm.
→ After adjustment, the left and right knee lever wheel locks must both have the same braking force.

7.4.2 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. 23, 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. 23, 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. 23, item 2) until the scraping noise at the rear wheel disappears and
the wheel runs freely.
3) Tighten the counter nut (see fig. 23, item 1) until the adjustment screw is fixed.
→ The braking force of both rear wheels must be adjusted equally.
