BX 11
| Active wheelchair

4.8.2. Height of the front wheel

After adjustment of the rear wheel position, the correct position of the
steering wheels must be checked and readjusted if necessary.
• Unscrew the axle (Allen key, SW 4) and take it out completely (Fig.
37).
• Place the steering wheel in the right position for the required seat
height.
37
• Reinsert the axle into the steering fork and tighten it up again.
• The steering axle should be as as close to perpendicular to the
floor as possible. This ensures directional stability and safe driving
behaviour.

4.8.3. Angle of the steering axle

By changing the height of the driving wheel or front wheel, the angle
of the steering wheel axle can also be altered. However, this should
always done at the correct angle (90°) to the ground. First, loosen the
38
locking mechanism of the castor connector by loosening both screws on
the outside (see Fig. 38). The setscrews within the castor connector are
used for fine adjustment and to secure them in the specified position.
Move the front wheel to the required position and then tighten the
fixing screws again.
Further details can be found in the installation manual.

4.8.4. Wheelbase

Extending the wheelbase increases the stability and equilibrium
of the wheelchair. On the other hand, if the wheelbase is reduced,
this improves manoeuvrability. A reduction of the wheelbase is only
advisable for experienced drivers.

When the wheelbase is changed, it is absolutely
essential to adjust the parking brake afterwards!

4.9. Wheels and tyres

4.9.1. Full floating axle

The BX 11 comes standard with full floating axles.
The full floating axles make it easy to attach and detach the wheels.
• Press the locking button of the full floating axle with your thumb
and pull the wheel off (Fig. 39).
• When reattaching the wheel, simply push the wheel back onto the
mount. At the same time, press in the locking button as well.
Check if wheels are securely seated each time they got reattached!

4.9.2. Drive wheels

The BX 11 is equipped with 24" x 1" drive wheels with pneumatic
tyres as standard. Schwalbe Marathon plus puncture resistant tyres are
optionally available. If they become worn or defective, the authorised
specialist retailer should be asked to carry out the repair.
To ensure the optimum operating safety of the brakes and wheelchair,
pneumatic tyres must be inflated to the tyre pressure indicated on the
tyre.

4.9.3. Steered wheels

6" (150 x 30 mm) PU tyres (puncture resistant, no valve) are mounted
on the BX 11 as standard. If they become worn or defective, the
authorised specialist retailer should be asked to carry out the repair.
If the BX 11 is equipped with pneumatic swivelling wheels, the tyres
must be inflated to the pressure indicated on the tyre to ensure
optimum operating safety of the wheelchair.
