It is dangerous if the work equipment moves by mistake
when replacing the side cutter and shroud of the bucket.
Set the work equipment in a stable condition, set the lock
lever securely to LOCK position (L) and stop the engine.
As the pin is driven out with strong force, it is dangerous
that the pin may fly out. Check that there is no people in
the surrounding area.
Broken pieces may fly during the replacement work, so al-
ways wear the protective equipment such as protective
eyeglasses and gloves.
