CAUTION
Unsecured screw connections
Pinching, crushing, tipping over, falling of user due to assembly errors
►
Always firmly re-tighten the mounting screws and nuts after changing settings. Observe the specified torques
in doing so.
►
Any time you loosen a screw connection with thread lock, replace it with a new screw connection with thread
lock or secure the old screw connection with medium strength thread locker (e.g. Loctite 241).
►
Always replace self-locking screws and nuts with new self-locking screws and nuts after disassembly.
Fine-tuning and adjustments should always be carried out in the presence of the user. The user should be sitting
upright in the wheelchair while making adjustments.
All parts of the product should be cleaned thoroughly before adjustments are made.
The tools required for configuration and maintenance are summarised in the section "Appendices" (see page 33
ff.).
6.2 Adjusting the drive wheels
WARNING
Lack of fine adjustment of the drive wheels
Tipping over, falling of the user due to incorrect adjustment
►
Check the standard adjustments of the wheelchair for stability against tipping and function of the drive
wheels. Avoid any extreme settings.
WARNING
Incorrectly adjusted wheelbase
Tipping over, falling of the user due to unstable settings
►
Please note that with the drive wheel in a more forward mounting position and with an unfavourable body pos
ition, the user may tip backwards even on level ground.
►
Use an anti-tipper for inexperienced users and with extreme settings of the drive wheel.
►
Be sure to position the drive wheels towards the rear for transfemoral amputees. This improves the stability of
the wheelchair.
INFORMATION
Changing the drive wheel position can also change the angle between the caster wheel journal and the ground.
However, this must always be
approx. 90°
and thus readjusted accordingly. The knee lever wheel lock also has
to be readjusted.
6.2.1 Setting the drive wheels horizontally
The horizontal position of the drive wheels can be changed by horizontally shifting the drive wheel adapter.
Changing the drive wheel position has the following effects:
Position of drive wheel
Effects
Move backwards (passive setting) •
Larger wheelbase
•
Larger turning circle
•
Greater stability of the wheelchair
•
Wheelchair is harder to tip backwards when crossing obstacles
•
Position recommended for inexperienced users
Move forwards (active setting)
•
Smaller wheelbase
•
Less load on caster wheels = greater manoeuvrability
•
Less stability of the wheelchair
•
Wheelchair is easier to tip backwards when crossing obstacles
INFORMATION: An anti-tipper should be installed if necessary.
•
Setting recommended only for experienced users
The drive wheel adapter can be installed at four depth positions in the frame.
1) Remove the drive wheels.
