DRIVING BEHAVIOR
The first adjustment of the driving fea-
tures of your wheelchair to suit your per-
sonal needs will be possible at once,
following a brief “introductory “ phase
of
driver training
.
!
Attention:
Drive with extreme caution during
these first trips.
Please follow all instructions in the
section “Driver Training”in the bro-
chure “Safety Information - Mechani-
cal Wheelchairs”!
You will be confronted with new situa-
tions during each trip and will have to
cope with these, as is the case in all
areas of life, e.g. family, career, lei-
sure pursuits. Utilise the folding wheel-
chair's adaptability to the needs of the
user. This offers you outstanding driving
comfort and high operational safety.
This operating manual will give you all
necessary information.
!
Attention:
Please follow all instructions in the
brochure “Safety information - Me-
chanical wheelchairs”.
Avoid sudden change to the opposite
direction, (e.g. change to forward
drive after driving backwards with-
out any movement of the steering
wheel). – This can lead to accidents
due to full braking while steering
wheels are moving inwards!

Remark:
The components shown in the fig-
ures are not always identical with
your wheelchair model. Position
and handling of the parts that are
operated will apply to all wheel-
chair models. Always check that
components are fixed correctly af-
ter assembly as well as after any
adjustment or modification.
PARKING BRAKE
The parking brakes are part of the most
important safety elements of a wheel-
chair.
!
Attention:
Please observe the Maintenance In-
structions as well as instructions in the
section “General Safety Information”
and “Brakes” in the brochure “Safety
information - Mechanical wheel-
chairs”!
Your PRIMUS II is equipped with pres-
sure brakes (Fig. 2) which act directly on
the tyres.
Service brake
Gently and evenly press both brake le-
vers [11] slightly forwards. This way,
you brake the wheelchair in a measured
way.
!
Attention:
If only one brake is applied when the
wheelchair is driving down an in-
cline, the free-running wheel will con-
tinue moving around the locked
wheel. Depending on the gradient of
the road, this can lead to the wheel-
chair overturning to the side.
!
Attention:
Do not park wheelchairs with PU
wheels with applied pressure
brakes. – This can cause accidents
during regular braking due to some
remaining deformation in the sur-
face.
