9.1.3. Angle of the steering axle
By changing the drive wheel position or that of the front wheel, the
angle of the steering axle can also change. However, this must always
be at a right angle (90°) to the ground (Fig. 40).
• Release the castor bushing lock by loosening the two screws on the
outside (Fig. 40). Fine adjustment and fixing in the specified positi-
on is done by the pin screws inside the castor bushing.
• Move the front wheel to the desired position and then tighten the
90°
40
fastening screws.
Further details can be found in the assembly instructions.
9.1.4. Wheelbase
Extending the wheelbase improves the stability and sturdiness of the
wheelchair. Reducing the wheelbase, on the other hand, improves ma-
noeuvrability. Reducing the wheelbase is only recommended for expe-
rienced drivers.
9.2. Adjusting the locking brakes
To adjust the brake, contact your specialist dealer.
Remember that incorrectly adjusted brakes can have
life-threatening consequences.
If the brakes only work insufficiently or unevenly, contact your specia-
list dealer. He will check the brakes as follows:
• If there is uneven wear of the tyre tread, or if the tread is no longer
visible, change the tyre.

If the wheelbase is changed, subsequent adjustment
of the knee lever brake is absolutely necessary!

• If the profile is no longer visible on the brake pin, change the brake
pin.
• Move the brake system into position that provides safe braking in
all driving situations and is operable.
• To adjust the distance, loosen the two hexagon socket screws on
the brake bracket (Fig. 41).
• Then slide the brake system along the bracket into the correct
position.
• Tighten the two screws again.
• Check that the brake fully engages when the lever is operated and
does not snap back.
• Then tighten the screws again and carry out a brake test!
Check that both drive wheels have an air pressure
of 7,5 bar.
9.3. Adjusting the drum board
To adjust the brake, contact your specialist dealer.
Remember that incorrectly adjusted brakes can have
life-threatening consequences.
To achieve an optimal braking effect, the braking force is adjusted at
the adjusting screw. The braking force is increased by unscrewing the
adjusting screw and decreased by screwing it in (Fig. 42).
• Please turn out the adjusting screw until you hear grinding noises
on the turning wheel.
• Then turn the adjusting screw in until the grinding of the wheel
disappear. The wheel then runs freely.
• After finishing the adjustment, fix the adjusting screw by tightening
the lock nut.
