Tightening the V-belt/Checking the tension
NOTICE:
To obtain the maximum cutting performance at the lowest fuel con-
sumption, it is absolutely necessary to tighten the V-belt precisely. An
incorrectly tightened V-belt leads to premature wearing of the V-belt
and V-belt pulley or to damage on the clutch bearing. Retighten the
V-belt after one hour of operation!
NOTE:
To tighten the V-belt and to check the tension, you must loosen
both mounting nuts (
11
).
To increase the tension, turn the tension screw (
12
) in the clockwise
direction with the combination wrench included in delivery.
The V-belt is correctly adjusted if the marking (
14
) is centered between
the nuts (
13
).
NOTICE:
After tightening/testing the V-belt, make sure to
tighten the mounting nuts (
11
) to 30 + 2 Nm (22 + 1.5 ft.lbs.).
