Follow these steps for fine-adjustment of seat collapse force. Use this setting if the wheelchair user
requires a lower force to lower the seat while sitting, while maintaining a higher lifting force while
standing. Primary lift force adjustment should be done using the main lift force adjustment described in
the previous step.
•
WARNING: Do not attempt to adjust force while the wheelchair or lift seat is occupied.
a. Access the collapse force adjustment by
removing the bottom strap of the front cover,
as shown. (figure 23)
b. Adjust seat collapse force by using a 3/16
inch hex wrench to turn the counterbalance
adjustment screw to the desired position.
The screw may be set at any position, as
desired. (figure 24)

selected, replace the front cover lower strap.

seat force. Ensure that the seat is providing
stability while sitting and force assistance while
standing. If necessary, make adjustments to
the force setting based on user's preference.
