7.5 Blade maintenance
The condition of the cutting blades should be checked at least after every few uses The blades wear down in
normal use and can get damaged if hitting a rock or other obstacle.
If the cutting results have weakened from the original, the cutting blades have probably become blunt or some
of the blades have been damaged. Uneven cutting results, increased power requirement and increased
vibration level are signs of blunt or damaged blades.
To protect the blades and other components when hitting rocks or other obstacles, the blades are fitted to the
axle in a way that allows them to move. Check that all of the blades move freely and are not stuck. The Y- and
L-type blades are sharpened from the both sides and they can be installed the other way round. When
reinstalling the blades, make sure, that you fix them in the same manner as they were originally. Do not over
tighten the blade screws.
The fastening bolts and nuts must be replaced with new ones when replacing blades.
WARNING
Hazard of thrown objects - Check all blades are connected securely.
Check that all
blades are connected securely and that none of the blades is missing. Loose, damaged,
or missing blades can cause ejection of parts from the mower. Only use locking nuts for
fastening the blades.
If the blades have large notches or cracks, or if they have worn down excessively, they
must be replaced. Always use good protective gloves when handling the blades.
Check that the flail mower is balanced to avoid damage to the bearings. Repair the
mower, if you notice any abnormal vibration or noise. Contact service for assistance.
