7.2 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.).
