Service manual
General
Introduction
This service manual is part of the instructions and contains the technical
information for servicing, conguring 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:
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.
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.

Seat
Seat width (SB)
Available seat widths: SB 340 to 480 in 20 mm steps.
Changing the seat width is very complicated. The seat module, the backrest, the real wheel axles and
the footrest have to be replaced.
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 inuence the seat height.

Rear seat height (SHh)
The seat braces can be repositioned to adjust the rear seat height. The
seat braces are available in three dierent sizes, covering seat heights of
between 380 and 490 mm.
Generally, we recommend xing the seat braces to the lower hole on the
frame.
