3.11.2 Replacing the Wheel Attachments for Wheels with Quick-Release Axle

CAUTION
Prohibited changes of the wheel size/installation position
Risk of injury or damage due to altered driving characteristics or breakage of load-bearing components
► Only replace wheels with wheels of the same size and use the previous installation position. Changes could
have incalculable effects on the stability of the product when driving.
1) Remove the wheels (see Page 31).
2) Loosen the hexagon nuts on the wheel attachments (see Fig. 83, item 1; see Fig. 84, item 1).
INFORMATION: The manufacturer recommends replacing both wheel attachments at the same time.
3) Remove and replace the wheel attachment.
4) Thread a hexagon nut approx. 11 mm onto the side with the broad edge of the wheel attachment, respectively
(see Fig. 85).
5) Slide the wheel attachment into the rear wheel adapter in the original position from the outside.
6) Slide a lock washer onto the wheel attachment from the inside (see Fig. 83, item 2).
7) Tighten the inside hexagon nut to a torque of 50 Nm (see Fig. 83, item 1).
INFORMATION: Avoid scratching the rear wheel adapter during tightening.
8) Reattach the wheels.
9) If required, adjust the length of the quick-release axle by turning the hexagonal (no illustration).
→ Ensure that the locking mechanism disappears fully in the quick-release axle after releasing the pushbutton.
If this is not the case: slightly increase the length of the quick-release axle (maximum adjustment range
2 mm). In order to do so, turn the hexagon nut on the quick-release axle anti-clockwise in small increments.
→ Ensure that the quick-release axle is seated in the wheel attachment so it is free of play. If this is not the
case: shorten the quick-release axle. In order to do so, turn the hexagon nut on the quick-release axle
clockwise in small increments.
