Adjusting the drive belt

• The drive belt is fully
enclosed and well protected
from dust, dirt and
mechanical effects during
the cutting process.
• To tension the drive belt,
slightly loosen the bolts (A),
which secure the cutting
head and belt guard.
• Turn the tensioning screw
so that the nut (B) is located

tension the belt. The belt
now automatically has the
right tension.

the cutting head.

tensioned after using one or two tanks of fuel.
