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
Dicult – 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 à 3, 4, 5
Phillips screwdriver Ò 2
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 insucient 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.
i Ensure 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
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.

Replacing the handle
An adhesive (e.g. hair spray) is used in these instructions. When
applied to the handle, this substance works as a lubricant and as an
adhesive once dry.
After drying, the adhesive used must be able to resist a pull-o
force of 750 N. If in doubt, contact Küschall® AG.
Diculty:
Remove the old handle.
Remove any residue (residual adhesive, grease, dust) from the
push handle tube.
Apply a thin layer of hair spray all over the surface of the push
handle tube onto which the handle is to be slid.
Apply a thin layer of hair spray to the inside of the handle.
Slide the new handle onto the push handle tube.
Move the handle into the correct position (grooves facing
upwards).
i
If a long handle has been fitted and this is to be replaced with a
short one, the push handle tube must be shortened by 35 mm.
The push handle tube must be replaced when switching from a
short to a long handle.
