Non-folding back instructions
1.
Remove backrest bracket bolt (A).
2.
Rotate the backrest to the desired angle.
3.
Align desired backrest bracket hole with seat frame opening.
4.
Re-insert 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.
M. REAR AXLE ADJUSTMENTS
1.
Wheel Camber
Wheel camber, shown as angular relationship (B), provides greater side-to-side stability due to the increased
width and angle of the wheelbase. It also allows for quicker turning and greater access to the top of the han-
drims.
Wheel camber is determined by pairs of interchangeable camber plugs which are available from your authorized
dealer in 0º, 3°, and 6º angles.
2. Changing the Camber Plug
Before changing the camber plug, note the camber tube bolt positions.
a.
To change the camber of your chair, loosen bolt (D) on both camber tube clamps (E). Then loosen the
second bolt(F). Repeat on other side.
b.
Now the camber tube (C) and camber tube clamps (E) can be removed from the axle plate (G).
c.
Once removed from the axle plate, the camber tube clamps can removed from the camber tube. You can
now remove the camber plug (H).
d. Insert the desired camber plug into each end of the camber tube. Then replace the camber tube clamps
on the ends of the camber tube. Be sure to space camber plugs equal distance from the ends of the cam-
ber tube.
e.
Slide camber tube assembly onto axle plate. Realign axle plate holes to their original position. Tighten
bolts (D) then replace and tighten all bolts to 100 in-lbs (11.3 Nm)
3. Setting toe-in toe-out to the ground
NOTE – A wheelchair equipped with 0° camber plugs cannot have a toe-in toe-out condition. This adjustment is
only required when using 3°, 6° camber plugs.
“Toe” refers to how well the rear wheels of the chair are aligned relative to the ground. It affects how well the
chair will roll. Drag or rolling resistance is optimally minimized when the wheel toe is set to zero.
4. Setting the Toe to Zero
a.
Place the entire wheelchair on a flat horizontal table or ground surface. Loosen the 2 cap screws (D) (1
per side) that secure the camber tube clamp.
b.
Locate the flat surfaces on the front and rear of the camber plugs (E). Place an object that is known to
have an accurate 90° corner (such as a carpenter’s square, drafting triangle, etc.) down on the flat hori-
zontal surface and up against the flat of the camber plug.
c.
Rotate the camber tube and plug assembly until the flat surface of the camber plug is parallel to the
measuring tool.
d. Before tightening the screws (D), make certain that the camber tube is centered left-to-right relative to
the wheelchair frame. There should be an equal gap on both sides of the wheelchair or none at all. Torque
the fasteners to 100 in-lbs. (11.3 Nm).
