Link Rear Suspension

WARNING!
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 (A)clockwise
(looking up at the suspension system
from underneath the wheelchair).
b. To soften the suspension, turn the
spring preload adjustor (A) counter-
clockwise (looking up at the
suspension system from underneath
the wheelchair).
2. Alignment of Suspension Link
Arms
Do not adjust the link arms (B). These
are set at the factory to ensure proper tracking
and performance of the 4-Link Rear Suspension system.
Setting the Toe to Zero
Loosen the cap screws (A) (3 per side, unless equipped with
anti-tips then 4 per side) that secure the camber tube clamp.
Observe the ball in the level (B), and rotate the camber tube (C)
until the ball is centered in the level. The toe is now set at zero
(Fig. 5.7, 5.8).
Before tightening the screws (A), 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 (A) to 62 in-lbs. (7 Nm).
Setting the Toe to Zero–
Alternative Method
Place the entire wheelchair on a flat
horizontal table or ground surface.
Loosen the cap screws (A) (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 (D). Place an object
that is known to have an accurate
90° corner (such as a carpenters
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 is parallel to the
measuring tool (Fig 5.7, 5.8, 5.9,
5.10).
Before tightening the screws (A), 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 (C) that connects camber
clamp to the shock camber clamp.

Footplate Adjustment

Adjusting the footrest
CAUTION!
Do not stand on the footboard!
Even if the user is
sitting in the chair, there is still a
risk of tipping over and injury.
CAUTION:
When transferring, do not stand
on the footboard, there is a risk
of tipping over and injury.
Releasing the screw (1) will allow
you to adjust the footrest to
correspond to the length of your
lower leg and re-attach the footrest.
The angle of the footrest may be
individually adjusted by loosening
screws (2). The side protection (3)
on the footrest prevents the feet
slipping off accidentally. make sure
that after any adjustment work, all
screws are tightened correctly (see
the page on torque) (Fig. 5.12).
High-mount footrest
The high-mount footrest is fitted on
the inner part of the frame
and permits a higher footrest position
(Fig. 5.13).

Seat

Adjusting the seat height
To adjust the rear seat height
release
the Allen screws (1) (one on each
side), which fix the clamp to the
axle stem (2). Remove the spacer
bracket (3), to adjust the seat height
+/- 1 cm. For large adjustments,
reduce the length of the axle stem
as required.
Tighten the 2 Allen screws to 7 Nm. (Fig. 5.14).
NOTE:
An adjustment to the castor angle may be necessary when
adjusting the rear seat height .
