Tool recommendation:
The angle with slider can be ordered from
PRO ACTIV (order number: 8000 901 000).
If the front edges of the caster wheel bearing
blocks are not standing vertical to the level
ground, the settings must be adjusted.
First,
adjust
the right caster wheel bearing block,
then the left one, and finally check the right
side again. Depending on the type of caster
wheel bearing block, proceed as described in
one of the following two sub-chapters:
22.4.1 Adjustment of caster wheel bearing
block, welded
To adjust the caster wheel bearing blocks,
proceed as follows:
1. Loosen the M5 stud bolt (AF 2.5 mm).
Figure 82: Stud bolt
2. Undo the M6 fixing screw (AF 5 mm)
slightly on the frame inner side.

3. Now slightly loosen the M6 fixing screw
(AF 5 mm) on the outside of the frame.

4. Using the aid of the angle, move the caster
wheel bearing block in a vertical position to
the level ground.
5. Tighten the M6 fixing screws (AF 5 mm)
again on the frame outer and inner side to
a tightening torque of 10 Nm and recheck
the vertical setting.
6. Screw the M5 stub bolt (AF 2.5 mm) back
in so that this rests on the M6 fixing screw.
After performing adjustment work on the
caster wheel bearing block twice, renewing the
screw locking fluid for the M6 fixing screws (AF
5 mm) on the outer and inner sides of the
frame is recommended.
Note:
To reduce caster wheel flutter, it may be nec-
essary to tilt the caster fork rotary axles from
the vertical (Chapter 22.4).
