Avoid Driving Bucket Teeth into Ground

d
WARNING: If the bucket teeth are forcedly driven into
the ground, crushed material may spatter, possibly
resulting in injury of the operator and/or co-workers
around the machine. Furthermore, the service lifetime
of all front attachment parts may be shortened.
If the bucket teeth are forcedly driven into the ground, the
service lifetime of all front attachment parts (especially the
bucket) may be severely shortened. When excavating tightly
fastened gravelly soil, use the bucket digging out force.
Operate the boom, arm, and bucket simultaneously so that the
bucket teeth can be effectively penetrated into the excavation
surface. Carefully operate the machine to prevent crushed
material from spattering, possibly resulting in injury to the
operator and/or co-workers around the machine.

front attachment parts may result.
Hammering or piling work with the bucket may create
hazardous situations. Never attempt to perform hammering
or piling work with the bucket. Damage to the bucket and the
front attachment parts may also result.
