BRAKES

The PROFI 3 can be upgraded with a
removable pressure brake, code 305
(Fig.6). It works directly on the tyres.
Benefits:
– controlled braking of the driving
speed (service brake)
– securing the wheelchair against acci-
dental rolling (parking brake).
Note:
The wheel cambering must be indicat-
ed when subsequently ordering a
pressure brake.
Please observe the Maintenance In-
structions as well as instructions in the
chapter " General Safety Information"
and "Brakes " in the brochure "Safety
information – Mechanical wheel-
chairs" !
Service brakes
Press evenly both brake levers (11) only
slightly forward for a controlled and di-
rection-stable braking of the wheelchair
(service brakes).
Parking brakes
You lock the brakes (parking brakes) by
pressing the brake levers forward until
the end stop is reached. – The wheel-
chair can then not be pushed.
Benefits:
– Controlled braking of the driving
speed (service brake).
– Secures the wheelchair against acci-
dental rolling.
– Adaptation to the sport rule (no
brakes) by way of removable
brakes, code 305.
Locking the pressure brakes
Push both brake levers (11) forward as
far as they will go (Fig. 7).
Note!
If only one brake is applied when the
wheelchair is driving down an incline,
the free-running wheel will continue
moving around the locked wheel.
Depending on the gradient of the
road, this can lead to the wheelchair
overturning to the side.
Releasing the pressure brakes
Pull both brake levers [11] back,
(Fig.6).
Adjusting the pressure brakes
– Loosen the clamping lever.
– Pre-set the pressure brake – Slide the
brake bolt of the non-activated pres-
sure brake to a point approx. 15mm
to 20mm in front of the drive wheel
(8).
– Tighten the clamping lever.
Note!
It should not be possible to push the
wheelchair forward when
brakes are locked.
The brake performance decreases
when the:
– tyre profile is worn
– tyre pressure is too low
– tyres are wet
– pressure brake is loose
– brake mechanism is defective.
Note:
You will find the values for the correct
air pressure for the wheelchair in the
Technical Specifications.
Defective pressure brakes
must be replaced!
