5.9 Wheelbase extension (optional)
Only to be performed by specialist staff:
Moving the rear wheel backwards extends the
wheelbase and therefore improves the stabili-
ty of the wheelchair.
Tools:
Allen key size 4 and open-end wrench
AF 10.
If the wheelbase is extended, the parking
brake must be modified to ensure that the dis-
tance between brake pin and tyre casing is 3-5
mm at the narrowest point as intended.
First, remove the rear wheels (see chapter
4.12). This secures the wheelchair against tip-
ping over. Next, loosen the two screw joints of
the adapter (1, Fig. 30) and pull the screws out
completely. Then, rotate the adapter vertically
by 180° (2, Fig. 30, 31) and fix it in place. En-
sure that all screws are firmly tightened.
On the model with the drum brake, the brake
cable must be detached before dismantling
the adapter. After, the adapter including the
drum brake is rotated vertically by 180°. After
mounting the adapter, the brake cable must be
correspondingly relocated and fixed in place
again.
To modify the parking brake as necessary, first
remove the locking brakes.

WARNING
Converting the wheelbase means all brakes
will have to be readjusted (see chapter 5.7 and
5.8).
