15 Safety instructions regarding
dangerous locations and
dangerous situations
The operator of the product determines the
route to be driven taking the operating
instructions, their driving knowledge and
physical abilities into consideration.
The personal driving skills are particularly
important in the following dangerous locations
which are provided as examples; the product's
user must use their judgement before driving in
such locations:
quay walls, landing and berthing locations,
paths and locations close to water,
unsecured bridges and dykes.
narrow paths, slopes (e.g. ramps and
driveways), narrow paths on a slope,
mountainous routes.
narrow and / or steeply sloping paths along
main roads or near cliffs.
routes which are covered in leaves, snow
or ice.
ramps and lifting equipment on vehicles.
When driving in a circle or turning on hills
or downward slopes, there may be an
increased tendency to tip over to the side due
to the changes in the centre of gravity. Always
perform these driving manoeuvres with
increased caution and only at slow speed. If
required, the driving manoeuvre must not be
performed or only with the help of an assistant.
When crossing main roads, intersections
and level crossings, extreme caution is
needed. Crossing rails in the road or at level
crossings must never be undertaken when
travelling parallel to them, as otherwise the
wheels could become caught which would
result in the product being unable to
manoeuvre.

Operating instruction RAPTOR 4all & 4you
When driving on ramps and lifting
equipment on vehicles, extreme caution is
needed. During the lifting or lowering operation
of a ramp or the lifting equipment, the service
brake should be operated. This prevents rolling
away.
The grip of the tyres on the ground is
reduced in the wet. There is an increased risk
of slipping. Adjust your driving, braking and
steering behaviour accordingly.
16 Functional elements
16.1 Pedal bearing support & crank
16.1.1 Seating position
The seating position and therefore the pedal
position and the crank length depend on the
upper-body stability or the core musculature as
well as the body size. A suitable adjustment
will have been made during the consultation /
measurement procedure.
The pedal position should be selected as low
as possible where the cranks however, must
not touch the users thigh when it is turning.
Moreover, the elbows should not be completely
extended when the crank handles point
completely forward away from the body and
the shoulders should rest against the backrest.
With weak core musculature, the seating
position and the crank length should normally
be chosen so that the upper body remains still
and always has a fixed contact with the
backrest when operating the crank while
driving. This is particularly important if you
have low seating stability due to missing or
weak core musculature. A rocking motion
(forwards and backwards) of the upper body or
the head should be avoided where possible.
For this, the correct setting of the backrest (see
chapter 17) and the correct choice of the crank
length as well as the pedal position is decisive.
If necessary, you should also use a hip strap or
chest strap for stabilising.
