Equivalent adjustments should be done to both the right and left suspension element.
It is important to properly adjust the pre-load and damping to ensure proper comfort and con-
trol for the rider.
1. Pre-Load Adjustment
With the rider seated in the chair and with batteries installed, insure that the main horizontal
member of the base frame is parallel to the ground. If it is not parallel, adjust spring collar (B) in
either direction to adjust. If the rear of the base frame is lower than the front, adjust the spring
collar clockwise when viewed from the rear of the chair. If the rear of the base frame is higher
than the front, adjust the spring collar counter-clockwise when viewed from the rear of the chair.
WARNING
The spring pre-load ring should never be adjusted so that the shock spring is
less than four inches long with the chair unoccupied and the batteries installed.
Too much spring pre-load may cause the spring to fail.
