11. the first set up
Before using, the wheelchair needs to be adjusted and set up for the user. In
this chapter we will explain all the setup which needs to be done before the
first drive.
11.1 chassis suspension
The suspension of a chassis has been designed to increase the comfort whilst
driving. Also climbing steps will be more easier having suspension on the
chassis. But suspension can also be a disadvantage. A suspension which is
set to soft has a negative influence on the control of the wheelchair. So it is
very important to have a good mix.
11.1.1 spring setting
The strength of the spring will be set by turning the ring shown above. By
turning it to the right (clockwise) the spring will have more tension and the
chassis becomes more stiff. This increases the mechanical traction en
improves control. The stiffness of the suspension depends on the user weight.
The settings needs to be done by setting and testing. We advise you to start
with a more stiff setting, since this results in the best control. If the suspension
is too hard, you can set it more soft by turning the ring more counter
clockwise. to make sure the balance of the left and right spring is the same,
we need to measure the setting.
before using the wheelchair it is vital to make the right set up for the user.
A non proper set up of the wheelchair might lead to uncontrolled driving
which can result in personal or material damage.
