Installation of the Dahl attachment plate on the drive support
1) Prepare access to the drive support:
→ In the equipment version without power seat functions: Remove the seat cushion and disassemble the
seat plate.
→ In the equipment version with power seat functions: Move the seat away from the battery cover as far
as possible.
2) Switch off the control device and remove the main fuse.
3) Slightly jack up the power wheelchair (see service manual).
4) Open the battery cover (see service manual). Disassemble the transverse and longitudinal bracing (see service
manual).
INFORMATION: Please note that, to complete the work, the longitudinal bracing has to be replaced
with the newly supplied longitudinal bracing from the Ottobock installation kit for the Dahl docking
system.
5) Remove the batteries (see instructions for use for qualified personnel or service manual). The floor of the drive
support is now freely accessible.
6) Place the spacer strips on the floor of the drive support in accordance with the illustration (see fig. 3, item 1).
7) Place the spacer plate on the floor of the drive support in accordance with the illustration (see fig. 3, item 2).
8) Have the 5 hexagon screws ready for installation at a later stage (see fig. 3, item 3).
9) Have the locking plate (see fig. 4, item 1) and the 3 matching intermediate pieces (see fig. 4, item 2) ready.
Also have the 5 Torx mounting screws ready for this purpose (see fig. 4, item 3).
10) Insert the Torx mounting screws one after the other from the bottom through the locking plate, the 3 intermedi­
ate pieces and the 5 holes of the drive support (see fig. 5).
11) Provisionally screw on the Torx mounting screws (see fig. 4, item 3) to the drive support from the top, using the
5 hexagon nuts (see fig. 4, item 4).
12) Mark the excess. Remove the screws, shorten them and carefully deburr the top.
WARNING! The screws must be flush with the hexagon nut. They may neither protrude beyond the
hexagon nuts or be too short to achieve their full holding force.
13) Re-insert the Torx mounting screws from the bottom and secure them with "medium strength" liquid thread lock
(e.g. Loctite 241).
14) Screw on the 5 hexagon nuts onto the Torx mounting screws from the top and tighten with 18 Nm (see fig. 4,
item 3/4).
15) Re-insert the batteries. Install the transverse bracing (see service manual).
16) Install the new longitudinal bracing (see fig. 6, item 1). To do so, fit the longitudinal bracing in the transverse
bracing (see fig. 6, item 2) and mount the longitudinal bracing on the drive support using the hexagon socket
screw, the washer and the hexagon nut (see fig. 6, item 3). The washer and the hexagon nut are positioned
inside the drive support.
17) Close the battery cover again (see service manual).
→ The locking plate of the Dahl docking system is installed under the power wheelchair (see fig. 7).
Installation of the attachments supplied by Ottobock on the VAS seat (protective pads)
1) Cut the hook-and-loop strap to size. Select the length so that the space between the pivot point and the reflect­
or is well filled (see fig. 9, item 1).
2) Stick the hook-and-loop strap to the cover diagonally below the pivot point.
3) Guide the protective pad over the cover and attach it to the hook-and-loop strap (see fig. 10).
4) Attach the second protective pad on the other side in the same way.
Installation of the attachments supplied by Ottobock on the standard seat (edge protection)
1) Cut the edge protection to size if required. The length is prescribed by the length of the edge of the end plate
(see fig. 11, arrow).
2) Position the edge protection on the edge of the end plate and press it on by hand (see fig. 12).
