Shock absorbers
Adjusting shock absorber spring force
The spring force of the shock absorber must be
adjusted to the correct value (see illustration).
The spring force can be adjusted to suit different
body weights by means of the adjusting nut.
Increase the value for a softer suspension, and
reduce the value for a harder suspension.
If possible in practical terms, the shock absorber
can be adjusted while still fitted in the chassis, but
the wheelchair must be empty at the time.

Shock absorbers
Removing the front shock absorber
1. Raise the seat; electric seat lift to the highest
position; fixed seat tube to the service position.
See page 28. If the electric seat lift does not
work normally because the batteries are dis-
charged or the adjustment device is defective,
the seat can be raised/lowered manually. See
page 26.
2. Switch off the main power switch on the con-
trol panel.
3. Remove the chassis covers. See page 8.
4. Lift up and chock up the wheelchair chassis so
that the wheel in question is free of the ground.

5. Unscrew and remove the two screws that hold
the shock absorber in place. See the illustra-
tion.
Fitting the front shock absorber
Fit in the reverse order. Adjust the spring force of
the shock absorber. It is easiest to do this before
fitting (see below).
Lubricate the bearing points (1) of the shock
absorber with grease before fitting.
