For setting the caster wheels for rotary axle,
the product should be standing on a level
surface and the wheel track of the drive wheels
must have already been set (see chapter
21.2).
Now check if the caster wheels for rotary axles
are standing vertically to the level ground. For
this purpose, place an angle with height
adjustable slider on the front edge of the caster
wheel bearing blocks. The slider should be
aligned to the middle of the caster wheel
bearing block.
If the front edge of the caster wheel
bearing block is standing vertically to the level
ground then the caster wheels for rotary axles
is also doing this.
Observe that the front edges of the caster
wheel bearing blocks are slightly rounded.
Thus, the distance above and below between
the slider of the angle and the front edge of the
caster wheel bearing blocks must be the same
size.
Figure 84: Checking and setting the caster wheels
for rotary axles
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. Then proceed as follows:
1. Loosen the M5 stud bolt (AF 2.5 mm).

2. Undo the M6 fixing screws (AF 5 mm)
slightly on the frame inner side.
