95 Tightening the V-belt
10.4 Tightening the V-belt
Note: 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. Do not retighten
the V-belt until 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).
Note: After you tighten/test the V-belt, make sure to tighten the mounting
nuts (11) to 30 + 2 Nm (22 + 1.5 ft.lbs.).
