3.5.6 Gearbox Control Lever Adjustment
It is important to correctly set the neutral position of the speed control lever on the gearbox in relation to the position-locked lever of the
speed selector on the handlebars. The the correct adjustment is set when the machine is assembled. If you find out that, with the selector
lever set to "N" (meaning the neutral) and, at the same time, the travel clutch lever pressed, the machine moves forward or backwards,
it is necessary to do the following:
check that the frame of the machine is not damaged,

check that the gearbox is not loosen or shifted in its seat in the frame.

The Bowden is adjusted on its attachment fitting in the rear of the left sideboard.

If you are not sufficiently manually skilled, have the operations done by an authorized service centre.
3.5.6.1 Gearbox Control Bowden Adjustment Procedure
1) Find out in which direction the machine moves when the neutral is selected.
2) Slightly loosen, with two 13 mm spanners, the internal and external nut on the Bowden bracket.
3) If the machine was moving forward, it is necessary to turn the inner nut counter-clockwise (i.e. the nut should be being
unscrewed). The firmly tighten the external nut.
4) If the machine was moving backwards, it is necessary to turn the inner nut clockwise (i.e. you should be turning the nut in the
tightening direction). The firmly tighten the inner nut.

The deviation as regards the position of the lever from the neutral position will never be large; in all cases turn the nuts
by ¼ of the turn at maximum.
3.5.7 Attachment Drive Clutch Adjustment

We recommend to let an authorized service centre do the activity for you.
The check and, if needed, the adjustment of the attachment tool drive clutch engagement moment should be performed after the 5
initial hours of operation and then after every 50 hours of operation. This service service action is also immediately necessary
whenever symptoms specified in the table occur.
Description of the clutch
behaviour
The start of the attached tool lasts
unusually long or the attachment
work tool slows down when
processing less material than
usually. It is possible to smell the
overheated clutch lining.
The brake does not work, but the
attachment drive can be engaged
normally; it is possible to start the
engine easily.
The brake works, the work tool
keeps moving jerkily, it is possible
to smell the overheated clutch
lining, it is not possible to start the
engine after being turned off.
Table 36: Clutch adjustment
3.5.7.1 Attachment Drive Clutch Adjustment Procedure
The adjustment is done unscrewing the adjustment bolt
chassis – see Fig. 11 on page 90 . Use 10 mm and 13 mm flat spanners.

For the purposes of testing the engagement and braking of the clutch, we recommend you to do the adjustment of the
clutch with the connected attachment with the active work tool.
1) Secure the machine against movement, e.g. by putting two suitable wood pieces to the both sides of the wheels (to the front and
behind the wheel). Switch the bypass lever to the manual travel position.
2) Secure the safety lock against the sudden unwanted initiation of the drive on the lever for engaging and disengaging the
attachment drive clutch in the pressed position. Use a plastic binding tape for the electric cables or a suitable highly adhesive tape.
3) Check whether the wire and the Bowden of the attachment drive clutch is without clearance. If it is not the case, adjust the
clearance of the wire and the Bowden so that there is no clearance.
4) Loosen the M6 nut with the 10 mm spanner
5) Hold the insert 6 in the frame
Bowden has no clearance in the adjustment screw.

Possible cause
It is first necessary exclude the
influence of the overfull work
area, the damaged work tool
shafts mounting and other
components of the drive of the
attachment, or the loss of the
engine output.
-
Broken return spring of clutch
control lever or broken clutch
plate; worn brake part of the
clutch or another defect of the
clutch.
4 of the attachment tool drive clutch Bowden on the back side of the upper
5 .
7 with the 13 mm spanner. Turn the adjustment screw
Influence on control
elements
The control lever exerts lowered
resistance when being shifted,
especially in the second half of
the motion.
Loose attachment drive clutch
Bowden cable.
-
Loose attachment drive clutch
Bowden cable.
It is possible to feel strong
resistance of the engine when
started and it is possible to hear
metal-rustling sounds; it is not
possible to restart the engine
again.

Solution
Adjust the clutch lining clearance
by unscrewing the adjustment
screw on the attachment drive
clutch Bowden fitting.
Worn brake part of the clutch; it
is necessary to replace the clutch
housing or of the carrier plate of
the clutch.
Abort the work immediately.
It is necessary to adjust the step
of the clutch lever.
An inspection of the machine in
an authorized service centre is
necessary.
