Introduction
This service manual is part of the instructions and contains the technical
information for servicing, conguring and repairing a Küschall® wheelchair.
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:

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.

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 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.
