
The caster wheel axles are no longer verti-
cal due to a fall or an impact.

The flattering of the caster wheels should
be reduced.
To adjust the caster fork rotary axles, the prod-
uct should be standing on a level surface and
the wheel track of the drive wheels should
have already been adjusted (Chapter 22.2).
Now check whether the caster fork rotary ax-
les are positioned perpendicular 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 at the middle of the caster wheel
bearing block.
Information:
If the front edges of the caster wheel bearing
blocks are perpendicular to the level ground,
the caster fork rotary axles are as well.
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.

TRAVELER usage instructions
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. To do this, proceed as follows:
1. Loosen the M5 stud bolt (AF 2.5 mm).
