CENTRE OF GRAVITY
The adjustment should be carried
out by the specialist dealer!
The centre of gravity is infinitely variable
by way of axle tube displacement.
!
Attention:
The overturning risk increases with a
reduction in the axle separation dis-
tance (Forward displacement of the
axle tube)!
The axle tube must be displaced in a
parallel manner for a perfect driving
behaviour. The separation distance
between axle tube and backrest
tube (A, Fig.31) must be the same on
both sides.
Handling:
PROFI 3-T, 2.874
Tools:
Open-end spanner WW* 10
Hexagonal stud wrench WW* 4
– Slacken the adjustment screws (A,
Fig.32) of the tube clamp.
– Move the seat parallel to the desired
separation distance.
OFFENCE, 1.879
Tools:
Hexagonal stud wrench WW* 5
– Loosen the adjustment screws on the
axle tube from underneath.
– Slide the axle tube parallel to the
desired separation distance.
WW* = Wrench width [mm]
TOE-IN
The adjustment should be carried
out by the specialist dealer!
The toe-in can be adjusted by rotating
the mount adapter (D, Fig.32) for the
axle.

Tools:
Open-end spanner WW* 10 and 22
Hexagonal stud wrench WW* 4
– Slightly slacken the adjustment screw
(C, Fig.32) of the tube clamp. – It
should be just possible to turn the
axle mount adapter with the open-
end spanner.
Set toe-in with attached drive wheels:
– Optically align drive wheels parallel
to the frame. – Do this by rotating the
axle mount adapters (D, Fig.32) in
the appropriate direction.
Fine adjustment:
– Adjust for equal front spacing be-
tween drive wheel and the frame
tube on both sides. – The spacing is
to be determined with, for example,
a ruler (Fig. 35).
+
Remark:
The above only ensures that the
drive wheels are positioned equal-
ly to the frame.
– Measure the front and rear spacing
between the drive wheels at the
same height (Fig.36).

– Detaching drive wheel. – Do this by
pressing in the stop knob at the centre
of the wheel and pulling off the
wheel.
– Slacken the adjustment screw (C,
Fig.32) of the tube clamp.
– Pull off the axle mount adapter.
– Insert the axle mount adapter with
the desired wheel camber in the
mounting tube.
– Lightly tighten the adjustment screw
(C).
– Attach the drive wheel (see
axle
).
– Adjust toe-in (see
Toe-in
).
– Convert other side accordingly.
