N. BACK ANGLE ADJUSTMENT
Backrest Adjuster Stop
The preset stop allows the ability to place a firm stop at desired angle. The hole pattern in the backrest adjuster
stop corresponds with the hole pattern in the backrest bracket (4 holes for each piece).
1. Determine the desired Stop Position.
2. Remove the lower backrest bracket butten head fastener (C) and loosen the top slightly (A).
3. Adjust the Backrest Adjuster Stop (B) into the Backrest Frame (A) to desired position.
4. Insert backrest bracket hardware (C) and retighten to 62 in.-lbs (7 Nm)
5. Repeat process on opposite side. Ensure both sides are using the same Stop Position.
Non-folding back instructions
1. Remove backrest bracket bolt (D).
2. Rotate the backrest to the desired angle.
3. Align desired backrest bracket hole with seat frame opening.
4. Reinsert bolt and tighten.
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.
O. 4-LINK REAR SUSPENSION
Rear suspension can affect the stability of the wheelchair. To avoid a fall, use a spotter and/or anti-
tips when becoming familiar with new equipment.
1. Tuning the 4-Link Rear Suspension
a. To stiffen the suspension, turn the spring preload adjustor (E) clockwise (looking up at the
suspension system from underneath the wheelchair).
b. To soften the suspension, turn the spring preload adjustor (E) counter-clockwise (looking up
at the suspension system from underneath the wheelchair).
2. Alignment of Suspension Link Arms
Do not adjust the link arms (F). These are set at the factory to ensure proper tracking and perform-
ance of the 4-Link Rear Suspension system.
3. Setting the Toe to Zero
Loosen the cap screws (G) (3 per side, unless equipped with anti-tips then 4 per side) that secure the camber
tube clamp. Observe the ball in the level ( J ), and rotate the camber tube (H) until the ball is centered in the
level. The toe is now set at zero.
Before tightening the screws (G), make certain that the camber tube is centered left-to-right relative to the
wheelchair frame, and the flat portions underneath outer camber tube clamp are parallel side to side. The end of
the camber tube should be flush with the outer most portion of the camber tube clamp. Torque fasteners (G) to
62 in-lbs. (7 Nm).
4. Setting the Toe to Zero– Alternative Method
Place the entire wheelchair on a flat horizontal table or ground surface. Loosen the cap screws (G) (3 per side,
unless equipped with anti-tips then 4 per side) that secure the camber tube clamp. Locate the flat surfaces on the
front and rear of the camber plugs. Place an object that is known to have an accurate 90° corner (such as a car-
penters square, drafting triangle, etc.) down on the flat horizontal surface and up against the flat of the camber
plug. Rotate the camber tube and plug assembly until the flat surface of the camber plug(K) is parallel to the
measuring tool.
Before tightening the screws (G), make certain that the camber tube is centered left-to-right relative to the
wheelchair frame and the flat portions underneath outer camber tube clamp are parallel side to side. The end of
the camber tube should be flush with the outer most portion of the camber tube clamp. Torque the fasteners to
62 in-lbs. (7 Nm).
NOTE– When turning the 4-Link Rear Suspension, always make one change at time and write down the
change. This takes patience, but allows you to understand how each change affects the ride of the
wheelchair in conjunction with rear suspension.
NOTE–
Lower shock mount is designed to have a loose feel, this is by design to allow for proper suspension
travel.
NOTE–
Never remove the barrel nut (I) that connects camber clamp to the shock camber clamp.
5. Maintenance for the 4-link suspension
a. Do not apply lubrication to shock end bushings or coils.
b. You can apply lubrication to the link ends after cleaning with a mild soap and soft brush.
c. Use a soft brush to clear any dirt or debris from coil system.
d. Never use a high-powered washer for cleaning the 4-Link Rear Suspension.
