7.8 Adjusting the caster wheels

Subsequently adjusting the seat height/seat inclination is possible with the following settings on the caster wheels
and caster forks.

7.8.1 Repositioning spacer washers in the caster head

INFORMATION
The spacer washers have to be repositioned evenly on both caster heads.
By repositioning the spacer washers in the caster head, the frame can be subsequently positioned horizontally and
the seat inclination can be corrected.
Perform the following steps, first on one side and then on the other:
1) Pry off the protective cap on the caster head using a screwdriver (see fig. 21, item 1).
2) Loosen the screw connection on the lower end of the threaded axle and remove it together with the caster fork
(see fig. 21, item 2).
3) Loosen and remove the screw connection on the upper end of the threaded axle (see fig. 21, item 3). In doing
so, secure the threaded axle so it remains in the caster head.
4) Position and secure the spacer washers (see fig. 22, item 1) as needed on the upper/lower end of the threaded
axle (see fig. 22, item 2).
5) Insert and attach the screw connections on the lower and upper end of the threaded axle together with the
caster fork (see fig. 21, item 2/3).
