General
Introduction
This service manual is part of the instructions and contains the technical
information for servicing, conguring 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
dealer.
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 instruc-
tion. 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.kueschall.com. Only original spare parts may be used. Installing
additional 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 loo-
sening 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.

5© Küschall AG,Switzerland | 2013-01
Service manual
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 specied 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 specied in the instructions regularly, 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.

Overview
Overview
Seat width (SB)
Available seat widths: SB 340 to 460 in 20 mm steps.
Changing the seat width is very complicated. The seat module, the back-
rest, the real wheel axles and the footrest have to be replaced.
Seat depth (ST)
Available seat depths: ST 360 to 520 in 20 mm steps.
To alter the seat depth, the complete seat plate as well as the seat cushion
may need to be replaced.
Front seat height (SHv)
The front seat height is dependent on several factors that interact with
each other - Frames, forks and front wheel sizes.
Chap. Front wheels, Shift supporter on the frame,
Chap. Front wheels, Replacing a front wheel,
Chap. Front wheels, Replacing a front wheel fork,
Chap. Frame, Mounting frame and seat plate.
Rear seat height (SHh)
The desired seat height is achieved through the proper position on the rear
wheel fastener on the vertical brace. The vertical brace is available in two
sizes (short and long) covering seat heights from 370 to 490 mm.
The wheel position and the rear seat height are innitely adjustable.
Chap. Rear wheels, Set axle position at the vertical brace.
Chap. Rear wheels,Tipping point adjustment.
Seat angle (SW)
The seat angle is determined by the dierence between the rear seat
height (SHh) and the front seat height (SHv).
