L. ADJUSTING REAR SEAT HEIGHT
Remove the set screws (A) on the rear side of the axle plate and the button head screw (B) on the
front. To increase the Seat To Floor Height add a spacer (C) to the camber tube clamp (D). To reduce
the Seat To Floor Height remove the spacer (C) from the camber tube clamp (D). No more than two
spacers per side are to be used. Once complete, insert the camber system (D) in the axle plate and
tighten screws to 62 in-lbs (7 Nm).
NOTE–
Adjustment to rear seat height may also require caster angle adjustment. See Section P.
NOTE–
If chair is configured with the 1B axle plate, the shorter camber tube clamps will be needed to lower rear
seat height by 1/2 inch. If configured with a 1A axle plate, it cannot be lowered and needs longer camber
tube clamps in order to raise seat height.
M. DEPTH ADJUSTABLE BACKREST
1
. The backrest may be adjusted by first removing the JAY style quick-release lanyard cord (not shown) from
the backrest release pins (E) on the inside of the chair frame. This will allow the pin and spring assembly
to be removed later in step 2.
2. Using a 5mm and 10mm Allen Wrench, remove the bolt holding the backrest bracket to the chair (F).
Repeat this step for the opposite side.
3. Once the backrest is removed, the quick-release pins and springs must be removed. The frame bushing
can be removed by reversing the quick-release pin and inserting the pin into the bushing (G). Slowly
remove the pin (H) as it's worked from side to side to pull the bushing out (Fig. 12). A pair of pliers may
be necessary to grip the exposed lip (I) of the bushing for complete removal.
4. If the desired back depth is 1" greater, move the plunger bushing back one hole. If the desired back depth
adjustment is 2", the plunger bushing must be moved to the most rearward hole. Insert the pivot bushing
received with the owners manual into the hole from which the original bushing was removed.
5. To reassemble the back, reinsert the springs into the bushings (J). Then reinsert the quick-release pins into
the bushings with the lanyard attachment holes first (K).
6. Reposition the backrest in place in the folded position. Insert the quick-release pin into its appropriate
placement hole.
7. Working on one side of the chair at a time, insert the large beveled washer (L) in between the backrest
bracket and the frame. Insert the backrest plate pivot bolt into the chair and secure using the washer and
nylock nut.
8. Using the 5mm and 10mm Allen Wrench, tighten the nylock nut so that the end of the bolt reaches the
end of the nut. Repeat on the opposite side of the chair.
NOTE–
Do not over-tighten the backrest plate pivot bolt as it may hinder the backrest from folding properly.
9. Reattach the JAY®-style quick-release lanyard to the quick-release pins.
NOTE–
This adjustment is intended to compensate for differences in after-market backrest thickness and/or
contour. The back-canes can be adjusted fore and aft relative to the seat so that the backrest support
surface does not change the location of the user, regardless of the backrest mounting location. This
ensures that the center of gravity of the user relative to the axle location, is not altered due to after-
market backrest thickness or contour. There is no recommendation for Depth Adjustable Backrest
use for transit.
