4.0 Hardware and MaTRx Back Installation
Important!
Prior to installation, ensure the
left
and
right
mounting plates
are in the proper orientation and secured to the back canes at the same height.
Important!
To function effectively and provide proper support, all MaTRx
backs should be centered between the back canes.
1
Remove existing wheelchair back upholstery (if applicable).
2
Establish the desired cane clamp/mounting plate seat depth configuration for
the end user (
as per Section 3.0
).
3
Loosen the screws on the
Lower Cane Clamp
ass’y and loosely install the clamps
(with mounting brackets) onto each back cane.
(Install plastic inserts if required
).
4
Starting with the
left*
back cane, position/slide the Lower Cane Clamp to the de-
sired height and tighten the clamp screws enough to hold it in place.
(Clamps
can be fully tightened after the back is installed and all final adjustments have been
made.)
5
From a fixed point on the wheelchair measure the exact height of the
installed
Cane
Clamp assembly, and install the second Cane Clamp at the
same height
on the
right*
back cane. Ensure the Cane Clamps/Mounting Plates are also mounted
parallel
with each other.
6
With the lower cane clamp assemblies installed, loosen the screws
on the
Upper
Cane Clamp
assemblies and install the clamps (with mounting brackets) loosely
onto each back cane- approximately 7” (18cm) above the lower clamp ass’y.
(Install
plastic inserts if required
).
(Clamps can be fully tightened after the MaTRx back is
installed and all final adjustments have been made.)
7
To install the MaTRx-PB elite back onto the mounting plates:
Step 1:
Slide the lower mounting pins from the MaTRx back into the notch in
the top of the lower mounting plates
Step 2:
With the lower pins in place, adjust the height of the upper cane clamp
ass’y as needed so that the upper pins (on the MaTRx back) lock/snap into the
latch mechanism of the Upper Mounting Plates.
8
With the Split Mounting Hardware (upper and lower clamp ass’y) properly ad-
justed, fully tighten all clamp assembly hardware.
9
The mounting pins for the MaTRx back may require adjustment to ensure the back-
rest is propely fitted/secured to the wheelchair.; For instructions on adjusting the
mounting pins, please refer to the installation manual provided with the MaTRx
Series back.
*note:
refer to
Figure 3.0
to confirm proper mounting plate orientation.
