HEIGHT ADJUSTMENT
When the platform arrives at floor level, the bridge plate should create a smooth and safe passage between the platform and
the vehicle floor. To create this smooth transition, the desired height can be adjusted using the following steps.
The lifting mechanism of the wheelchair lift consists of two hydraulic cylinders. The stroke of these cylinders can be altered to
a different length causing a different maximal elevation.
1.
Raise the platform to its highest position
2.
Check how much the height of the platform differs from the vehicle floor.
3.
Lower the platform a little bit to release pressure on the cylinders.
4.
Release the counter-nut (1) using a 30 wrench. Do this while fixating the cylinder rod (2).
5.
Turn the cylinder rod the correct direction. Lengthening it will result in a higher elevation. Alter this extension by applying
small increments of 3 turns or less, alternately to each cylinder.
6.
Raise the platform to its highest position. Check the desired height and make sure that both sides raise evenly. If this is not
the case, the cylinders were not adjusted to the same length. Lower the platform a few inches and repeat the previous step
until both conditions are fulfilled.
7.
Tighten the counter-nut.
