Troubleshooting Information
Check freewheeling function
The transmission features a freewheeling lever
which can be used to engage or disengage the
drive power.
Starting with S/N 10121, this freewheeling lever
is permanently mounted on the transmission link-
age. It is held in place in the engaged position by
a stop bracket.
Even with the drive engaged, the unit may be
slowly pushed by hand. However, the drive must
be disengaged (clockwise rotation) if the unit is
to be moved over extended distances.
–
Position 1: Transmission engaged
–
Position 2: Transmission disengaged
Note:
It is important to prevent inadvertent disen-
gagement of the freewheeling lever. Other-
wise, no drive power can be applied, and
engine braking will be ineffective.

Transmission drive belt
The transmission drive belt tension is adjusted
by means of the tension roller. The drive belt
must be sufficiently tight so that it will not wow
through more than 3 to 8 mm (0.12-0.32 in) when
applying a force of 2 kg ( 20 N) to the center of the
longest span.
Replace drive belt as required, ensuring that ten-
sion roller has first been relaxed.
