Usage instructions SPEEDY F4 & F2
If you have released both locking pins by pull-
ing on the cord, you can adjust the backrest as
desired and re-engage it by letting go of the
cord. In doing so, before applying load again,
make sure that both locking pins have en-
gaged safely into the desired locking holes (the
same position on the right and left).
A stop pin may be mounted in the backrest
angle adjustment range as a limiter.

Depending on the adjustment of the
backrest angle, check the tight engagement of
the backrest via the locking pins.
To fold down the backrest, pull on the middle
of the cord towards the front, and at the same
time, fold the backrest downwards until it rests
on the seating area. If you want to return the
backrest to the desired angle, proceed as de-
scribed at the beginning of backrest angle
adjustment.

18.2 Adjustable back & its adjustment
options
The "adjustable back and back padding" back
system consists of a belt system and back
padding. The slack of the backrest can be
adapted to the individual requirements via the
belts with tensioning loops.
First remove the back padding that has been
covered over which has been attached using
hook-and-loop straps. The belt system located
underneath has been set in the factory that the
top and the bottom belts have a slack of ap-
prox. 2 cm. The middle belts have been pulled
tight for a good lumbar support.
