The force of the brake lever can be adjusted
using the adjusting screws (Fig. 8 d). Use a
screwdriver and an SW 8 mm spanner. Oil
the joints of the brake at regular intervals.
IMPORTANT
In its standard setting, the brake bolt is
mounted in position (Fig. 8 e). It may be necessary to mount the brake bolt in position
(Fig. 8 f ) after adjusting the drive wheels.
Please contact your medical supplies dealer or PRO ACTIV for this purpose.
IMPORTANT
Please note that the toggle joint brake of
your wheelchair is a parking brake that
may only be applied when the wheelchair is
stationary. It is not suitable or intended for
reducing speed.
IMPORTANT
Please note that the distance between
the brake bolt and tire of the toggle joint
brake of your wheelchair when correctly
set (see 6.1) must be 3 mm to max. 4 mm.
Therefore, only use the hand rims to propel
the wheelchair. When propelling the wheelchair with the tires (thumb or finger on the
surface of the tire) there is a risk of fingers
and thumb becoming squashed between
the brake bolt and the tire.
6.2 Adjusting castor axle
To ensure good steering and directional
stability of your wheelchair, align the castor
axle vertically on even ground (Fig. 9).
The castor axles may require adjusting for
the following reasons:
You have altered the position of the
drive wheels
You have altered the height or angle of
the seat
The castor axles are no longer vertical
due to an accident or impact
The wheelchair veers to the left or right
when driving on even ground (the cause
may be uneven pressure of the drive
wheels)
6. MAINTENANCE AND CARE
We recommend regular (at least annually)
maintenance and care of the wheelchair by
PRO ACTIV or the medical supplies dealer.
In particular, the wheelchair should be serviced before and after intensive use, e.g.
during summer or winter vacations.
6.1 Adjusting toggle joint brake
It may be necessary to adjust the brake (Fig.

To adjust the toggle joint brake, proceed
as follows:
1. Loosen the fastening screws (Fig. 8 b)
that fix the brake to the brake plate
2. Position the released brake so that
there is a distance of 3mm to max. 4mm
between the brake bolt (Fig. 8 c) and the
tire
3. Tighten the fastening screws again
4. Check the correct setting of the brakes.
When the brake is applied, the drive
wheels should not turn when mediumforce pressure is applied. When the
brake is released, the brake bolt should
not rub on the wheel
