5.Secure the bottom of the NEW stabilizer cylinder to the mounting hole on the swing arm noted in STEP 2 with the mounting screw, washers, and locknut. Loosely tighten.
6.Secure the top of the stabilizer cylinder to the wheel- chair frame with the top mounting screw and locknut. Loosely tighten.
7.Torque both mounting screws to 13 ft/lbs and then back off 1/8 to 1/4 turn.
NOTE: The length of the new stabilizer cylinder must be adjusted to match the length of the stabilizer cylinder just removed.
8.Measure the distance between the top mounting hole and the bottom mounting hole on the existing stabilizer cylinder. Note this distance as distance “A” . Refer to DETAIL “A”
9.Place the wheelchair on a flat surface so that the stabi- lizer wheels can hang freely.
10.Loosen the jam nut, located underneath the hex nut adjuster, by turning CLOCKWISE as viewed from the top.
11.Rotate the hex nut adjuster in one (1) of the following directions:
A.Rotating the hex nut adjuster CLOCKWISE, as viewed from the top, will move the stabilizer wheel up.
B.
12.When distance “A” is achieved, noted from STEP 8, retighten the jam nut by rotating
13.Place the wheelchair on a flat surface with all six wheels in contact with the surface.
