7.7.3
Adjusting the camber
The optimum wheel camber is +0.5° (positive
camber), and is set by rotating the bushing (1),
using the open-end spanner 38 mm
(alternatively, a ring spanner or a ratchet with a
38 mm socket can be used).
This adjustment can be realised by rotating the
bushing either clockwise or counter-clockwise.
When the camber of the wheel is adjusted the
toe-in also changes. For this reason, it is
important to adjust the camber of the wheel in
such a manner that the distance between the
pivotal point screw of the trailing arm and the tyre
is as great as possible.
When the camber has been correctly adjusted,
then you must wait at least one hour before
driving the wheelchair, so that the metal
adhesive has enough time to harden. Otherwise
the camber will be out of adjustment.
7.7.4
Adjusting the toe-in
centring the steering servo
Before the toe-in can be adjusted, the steering
servo must be centred. In order for the steering
servo to centre itself, the drive wheels must have
ground clearance and be able to rotate freely.
• To centre the servo, switch on the driving
electronics, pull the joystick straight back
towards the rear and hold it in this position for
5 seconds. The servo will centre itself
automatically during the simulated reverse
drive. Afterwards, switch the driving
electronics back off again.
