Installation - Back Support Assembly
Installing the back support assembly.
WARNING: DO NOT allow wires or other components to
run through the support/hardware system at any time.
7 From behind the wheelchair, hold the back support and
hardware assembly on each side at the release levers (A)
with the release levers in the open position, as shown at
right.
Note: Holding the back support this way allows it to be
lowered evenly for better alignment.
8 Line up the female tracks (P) with the male tracks
(not shown) on the mounting bracket installed on the
wheelchair, and slide the assembly down.
9 Once the back support is close to the desired position,
lower the release levers until they click and are completely
engaged.
IMPORTANT! If a lever is not fully engaged (shown in
the center image below), move the back support assembly
slightly up or down until the lever clicks into place and is
completely engaged (shown in the right-hand image
below).
Not fully engaged
Setting the back support height.
Note: Each wheelchair manufacturer has a suggested "back gap" for
setting the height of the back support on the wheelchair. Refer to the
height recommendations and then evaluate the patient needs to set a
final back support height.
Note: The patient may be seated during step 10.

Flip the release levers open and then slide the back support up
or down to the desired height. Close the levers.
Before continuing, check the full range of articulation on the
wheelchair. See the warning below.
WARNING: To prevent injury or damage, the full range of
articulation on the wheelchair MUST be checked for any possible
interference or unwanted movement of seating components.

To lock the release levers in the closed
position: Using the hex key, turn the set screw
on the release levers until it makes contact.
CAUTION: DO NOT remove the set
screw. When the release levers are not
locked, make sure the set screw is flush with
the release lever surface.
