192 Driving and operation
Place the wheel recesses such that the
bicycle is more or less horizontal. Here, the
distance between the pedals and the
tailgate should be at least 5 cm. Setting the
wheel recesses – see page 190.
Both bicycle tyres must be in the wheel
recesses. In order to prevent damage,
neither the pedal bearing housing on the
bicycle nor the pedal crank must not be
touching the pedal crank recess.
Align the bicycle in the longitudinal
direction of the vehicle:
Slightly loosen the pedal bearing mount -
see page 189, Fig. S 14629.
Place the bicycle upright using the rotary
lever on the pedal crank recess - see
page 189, Fig. S 14629 or Fig. S 14630.
If the two bicycles obstruct one another,
the relative positions of the bicycles can be
adapted by adjusting the wheel recesses
and the rotary lever on the pedal crank
recess until the bicycles no longer touch
one another. Also make sure there is
sufficient clearance from the vehicle.
Tighten the attachment screw for the pedal
bearing mount to its maximum point.
Secure both bicycle wheels to wheel
recesses using strap retainers.
Check the bicycle to make sure it is secure.
The settings for the wheel recesses and on
the rotary lever on the pedal crank recess
should be noted and saved for each
bicycle. Correct presetting will facilitate
refitting of the bicycle.
