Adjustment of Toe-in
34
Adjustment
An important part of the steering system is the
adjustment of toe-in.
NB. Toe-in must be 2-4
mm measured at the centre line of the tyre.
Toe-in check
Check that the steering triangle is in the
position "straight ahead". Measure at the front
wheel's centre line. The distance between the
centre lines of the front of the front tyres must
be 2-4 mm less than the distance between the
rear of the front tyres.
Adjustment of Toe-in
1.
Remove the foot plate. See page 32.
2. Remove the protective plate under the
front wheel assembly. See page 32.
3. Check that the steering triangle is in the
"straight ahead" position. See the figure
to the right.
4. Loosen the M8 screws of the articulated
struts under the steering plate.
Loosen also the stop nuts furthest out on
both articulated struts
5. Turn the articulated struts on both sides
half a turn.
Check the measurement between the
centre lines of the front wheels. The
distance between the centre lines of the
front of the front tyres must be 2-4 mm
less than the distance between the rear
of the front tyres. See the top right figure.
6. Screw the articulated struts in place in
the steering plate.
NB. The articulated struts must be in
place when the measurements are taken.
When the distance is 2-4 mm, the stop
nuts must be tightened on both sides.
7. Fit the foot plate. See page 32.
8. Fit the protective plate under the front
wheel assembly. See page 32.

Adjusting the stop screws
Adjust the stop screws (M5) for the steering
triangle so that, at full joystick deflection, there
is a few millimetres' play between the steering
triangle and the stop screws.
