K. ANTI-FLUTTER KIT INSTALLATION
1. Remove fork assembly from chair. This may or may not require the removal of the caster
wheel.
2. Insert anti-flutter bushing (A) into the slot (B) at the rear of the fork ensuring the tab goes
between the ends of the snap ring and between the bearings.
3. Install clamp (C) over the top of the fork assembly inserting the inside tab (D) in the front
slot (E).
4. Gently flex the clamp tabs (F) apart to allow it to slide over the recently installed bushing (A).
5. Squeeze the tabs (F) back together and install the socket head cap screw (G) into the clamp,
ensure threads are properly aligned and lightly tighten using a 3mm hex key.

BACK ADJUSTMENTS
CAUTION – When changing the back angle of the wheelchair both the left and right angle adjustable back
bracket must be in the same hole position before the wheelchair is to be used.
Adjusting Backrest Options
The backrest bracket has two positions, 1 or 2, that can be achieved by removing bolt (H) and pivoting the back
cane forward or rearward. With the back cane in the desired position, reinsert and tighten the bolt. Then follow
the instructions for "Folding and Unfolding the Backrest".
1= Forward Mount. 2= Rearward Mount
Backrest Angle Preset Plugs
The preset plugs allow you to unemploy the backrest bracket holes you do not wish to use. This allows the
backrest to automatically lock into your desired angle position after unfolding.
1. Determine which backrest bracket holes you do not want to use.
2. Insert plugs ( J ) into the predetermined holes from the chair side of the bracket (K).
3. To ensure the backrest locks in the folded position, do not insert a plug into the lowest hole (L).
Depth Adjustable Back (DAB) Plugs
The DAB Frame insert plugs (M) allow you to compensate for a thicker or thinner after-market backrest with-
out having to change the Center of Gravity (CG) of the person in the wheelchair.

. The backrest may be adjusted by first removing the JAY
from the backrest release pins.
2. Using a 5mm and 10mm hex key, remove the bolt holding the backrest bracket to the chair.
3. Remove the quick-release pins, frame bushing, and springs.
4. If the desired back depth is 1" (2.5cm) greater, move the plunger bushing back one hole. If the desired
back depth adjustment is 2" (5cm), the plunger bushing must be moved to the most rearward hole.
5. To reassemble the back, reinsert the springs into the bushings. Then reinsert the quick-release pins into
the bushings with the lanyard attachment holes first.
6. Reposition the backrest in place in the folded position. Insert the quick-release pin into its appropriate
placement hole.
7. Insert the large Belleville washer 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 hex key 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. Re-attach 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.
