Warning
Wear or damage to the blades and the fastening elements
can result in the blades or the fastening elements coming
off.
► Check the blades and all fastening elements according
to the following instructions.
Warning
There is a considerable risk of injury due to improperly
mounted and maintained blades.
► Work on blades must be carried out by an authorized
service center.
Use solid gloves when you check the blade.
Work on the blade requires specific expertise because an im-
balance inspection is necessary and torques must be ob-
served.
Check the blade and all fastening elements for wear, damage
and cracks
– each time before and after you mow.
– if there are noticeable changes.
All shown blade parts and their fastening elements must be
changed
– if damage or cracks are detected.
– at least once a year or every 50 operating hours, no matter
if wear exists or not. The material weakens, one can suffer
cracks, endangering people and objects.
Vibrations are an indication that
– the blade is worn excessively or on one side or
– damage to the engine or cutter deck fastening has oc-
curred.
Blades that are sharpened improperly increase the workload
of the device and can result in vibration cracks or breaks.
Ejected broken pieces can cause severe injuries.
