Service Manual
GENERAL
Introduction
This service manual is part of the instructions and contains the tech-
nical information for servicing, configuring and repairing a küschall®
wheelchair.
WARNING!
Danger of accident and severe injuries.
If the wheelchair is improperly set it can cause
accidents and severe injuries.
▸Changes to the wheelchair may only be carried out
by the provider.
To guarantee the required safety and reliability, all wheelchairs must
be comprehensively checked once a year.
In part, assembly and adjustment require extensive experience.
For this reason, the following assembly instructions have been split
into three categories:
Requirement Symbol
Easy – technical understanding required 
Intermediate – specialist knowledge required 
Dicult – specialist wheelchair assembly knowledge
and experience required

The required tools and their respective sizes are listed above each
instruction. The instructions include information on the torques with
which the respective screw connections must be tightened. Adhering
to the given torques requires the use of a torque spanner.
Tools Symbol
Allen key Ã3, 4, 5
Phillips screwdriver Ò2
Straddle spanner 10, 11, 19
Socket spanner/ring spanner 8, 10
Spare parts and adaptations
All spare parts can be purchased from Küschall®'s Customer Services.
An electronic spare parts catalog is available by logging onto www.
kuschall.com. Only original spare parts may be used. Installing additi-
onal adaptations to a küschall®wheelchair requires the prior written
approval of Küschall AG.
Tightening Allen screws
Allen keys are not designed for greater forces. When tightening or
loosening an Allen screw, it is therefore advisable to apply force to
the nut to prevent the hexagon socket from being damaged.
Tightening and loosening
Turn the nut with a socket spanner (only use a straddle spanner
if there is insucient space) and merely hold the screw tight with
the Allen key.

Tightening and loosening if there is no nut
If an Allen screw is directly screwed into a screw thread, the screw must be tightened
using an Allen key.
iEnsure that the Allen key is of good quality and not worn.
Torque
All screw connections must be tightened with the torques specified in the following
instructions.
Checks
Visual check
Check the entire frame for cracks, especially the areas around joints and welded
seams.
Checking the screw connections
Check all bolts with the torques specified in the instructionsregularly, and adjust if
required.
CAUTION! Several screw connections have been secured with safety seals. If these are opened,
they must be secured again using new safety seals.
High-power and low power adhesives are available. For torque entries notice shall be
made whether an adhesive and which adhesive needs to be used.

Seat width (SB)
Available seat widths: SB 340 to 480 in 20 mm steps.
Changing the seat width is very complicated and requires the replacement of numerous parts.
Seat depth (ST)
Available seat depths: ST 375 to 525 in 25 mm steps.
Changing the seat depth requires the replacement of the complete seat module including the
seat cover and the seat rail and potentially also the seat cushion.
Front seat height (SHv)
The front seat height is dependent on several factors that interact with each other. The size
of the rear wheels determines the height of the sub-structure. In addition to the size and the
positioning of the brackets on the seat module, the frame, seat depth and rear seat height
influence the seat height.
