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 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:

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.

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 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
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.

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 specified in the following
instructions.
Checks
Visual check
Check all components for cracks, especially the areas around joints and welded seams.
Checking the screw connections
Check all bolts with the torques specified in the instructions regularly, and adjust if
required.
CAUTION!
Several screw connections have been secured with thread locking adhesive. If these are
opened, they must be secured again using new thread locking adhesive.
High-strength and low-strength adhesives are available. For torque entries notice shall be
made whether an adhesive and which adhesive needs to be used.
