11.1.2 damper setting
The spring damper unit has a red adjustment wheel on the end of the damper.
This wheel adjusts the rebound speed of the spring.
turning the red knob clockwise will make the movement of the piston going
out again faster. This decreases the damping of the spring damper unit.
Turning the knob counter clock wise will increase the damping. The right
setting will be done by stetting and testing whilst driving. The average setting
is halfway. This is set by counting the clicks from the totally left position to the
totally right setting. These are 16 clicks. Now set the setting by 8 clicks form
the end position.
to soft settings of the damper will result in a very spongy behavior of the
chassis. The control of the wheelchair will be bad. Avoid soft settings.
if the dampers are uneven set, it might lead to strange driving behavior of
the wheelchair. This might result in personal or material damage.
after setting the suspension, always drive first slowly and in an open
space to test the result of the setting.
