2.3.3 Seat height in back, seat slant

ATTENTION
After each change made on the rear wheels the function-
ality of the wheel lock must be checked and the casters
must be newly adjusted.
Generally, the seat height in back is about 2-3 cm lower as
in front, for a safe and comfortable seat position with a good
distribution of the seat pressure and to avoid a "sliding out".
However, other settings in individual cases can also be use-
ful.
• (1) Remove the rear wheels,
• remove the side guards/skirt guards with the
screws (A) (easily remove the desk side guard)
(2) remove the quick-release axle fitting including
•
all washers in the alternative holes (C)
• and retighten all screws. (tightening torque nuts
M18 fitting 35Nm).
• Mount the side guards and place the rear wheels
back in the quick-release axle.
�
INDICATION
The fittings must stick out of the perforated plate at the
same length on both sides. The fittings can only stick out
so that the side distance of the tires to the side guard is
as low as possible, however a min. of 10mm.

2.3.4 Steering head slant

ATTENTION
After every change on the rear wheel, the steering head
slant must be newly adjusted.
To adjust the caster adapter:
• (3) remove all screws (A) on both (!) sides,
• remove both screws (B).
• By tuning the adjust washer (C) (with a flat head
screw driver) place the adapter in a vertical posi-
tion (using an angle).
• Retighten all screws; screws (A) with 9 Nm, screw
(B) with 7 Nm.
�
INDICATION
A falsely set steering head slant can lead to the casters
shaking back and forth and can lead to hindering curve
rides (from casters).

ters and casters
