6.3.3 Replacing blades
Warning!
The blades are sharp. Always wear
gloves when working with the blades
to avoid injury.
Warning!
When replacing, both blades on the
same blade bar must be replaced to
avoid imbalance.
Check that the blades are always sharp. This
produces the best cutting results. The blades
should be replaced once a year.
Always check the blades after a collision. If the
blade system has been damaged, defective
parts should be replaced.
Always use genuine spare parts. Non-
genuine spare parts can entail a risk of
injury, even if they fit the machine.
The blades are replaceable. When replacing,
both blades on the same blade bar must be
replaced to avoid imbalance.
Attention!
Note the following when reassembling:
• The blades and blade bar must be installed
as in the figure.
• The blades can be turned 1/3 of a turn in their
mountings. Select positions so that the blades
