14.3 Check/change blades
WARNING
Missing, damaged or incorrectly mounted blades and blade supports
If blades are missing, damaged or incorrectly mounted, dangerous unbalanced rotation may
be caused and parts may fly around. People may be seriously injured or killed as a result.
Check the blades at least once a day and the retaining bolts every time after changing the
blades or after contact with foreign objects.
Immediately replace missing, damaged or incorrectly mounted blades and blade supports.
To avoid imbalance, always replace missing and damaged blades in kits and never mount
unevenly worn blades on a cutting disc/mower drum.
14.3.1 Checking the blade for wear
WARNING
Risk of injury due to low material thickness on the blades
If the material thickness on the blades is too low, the blades may loosen due to high rotating
speed. Thus there is a risk of serious injuries or death.
Replace the blades at the latest when the wear limit is reached.
ð The wear limit is reached when the borehole of the blade touches the marking (1) on
the blade or the dimension X is equal to or less than 13 mm.
