4.4. Brakes

The Pyro Next is equipped with parking brakes for user operation as
standard.

4.4.1. Setting the parking brake

The parking brake should only be used for parking. It is not suitable
for braking while driving! Use the push rims on the drive wheels for
that purpose. To decelerate, you grasp the highest point of the push
rims with your hands and let them be carried along by the wheel (Fig.
30). The push rims initially slide between your hands. Depending on
the force you exert when holding the push rims, you can change the
13
braking force from controlled deceleration to a sudden stop.
After the wheelchair has been decelerated in this way, activate both
tyre brakes by pushing the brake lever forwards. The wheelchair is now
securely braked (Fig. 14).
Pull the lever back towards you to release the brake (Fig. 15).

4.4.2. Adjusting the brakes

If you notice that the available braking effect is no longer sufficient or
is uneven, proceed as follows:
• With pneumatic tyres, always ensure that both drive wheels have
the same tyre pressure to achieve good directional stability!
• Check the tyre tread. Check also that the friction is even. If it is not,
or if the tread is no longer even visible, the tyre must be replaced.
• If you have the necessary technical knowledge, you can change the
tyre yourself. If you do not feel confident about doing this yourself,
your qualified mobility dealer will be able to help you.
• Now check the adjustment of the brake. This must be set so that
the gap between the surface of the wheel and the braking bolt is
8-10 mm with the brake off (Fig. 16). The braking bolt must be
• aligned horizontally, that is parallel to the ground surface.
• To adjust the gap, loosen the two Allen screws on the brake
mounting (Fig 17).
• You can then push the braking system along the mounting into the
correct position.
• Then tighten both Allen screws again.
• Make sure that the brake fully locks into place when the lever is
operated and does not snap back.
• After completing the adjustment process, tighten the screws
againand test the brakes!
Adjustment of the brakes should be carried out
by trained specialist staff. However, if you have
enough experience, you can also carry out this work
yourself. Nevertheless be aware that incorrectly
adjusted brakes may have life-threatening
consequences.
