WARNING
It is dangerous if the work equipment moves by mistake when the cutting edge or end bit is being re-
placed.
Set the work equipment in a stable condition, stop the engine, then lock the work equipment (the pilot
lamp in the switch lights up).
Turn or replace the cutting edge before the wear reaches the edge of the bucket.
