WARNING
1)
This machine is equipped with sharp blades. Wear protective glove for blade inspection and replacement,
and never tough the blades by hand. It may cause injury.

For blade replacement, use only genuine parts recommended by manufacturer. Manufacturer is not respon-
sible for the trouble and accident with non-genuine parts, and it is not covered by warranty.

In case of impact caused by hitting the stone block or stumps, stop the use and check if blade or blade disc
is bent, cracked or damaged. Replace them if necessary. Before each use, make sure if damaged parts in
previous use are properly repaired or adjusted.

Blades rotate in very high speed. Even with small lack of part or small bend, it leads to big vibration. To
continue operation with big vibration is dangerous and can be cause of clack on each part of machine. Ma-
chine’s service life may be much shorter in this case.
5)
Leaving the wear, bend, and lack of blades without maintenance may lead to serious accident such as thrown
object of broken blade, or to damage of machine itself.
