• Jobsites where long wear life is required, such as when loading hard rocks.
• Jobsites where no penetration is needed, such as when working with crushed rocks after blasting or rip-
ping.

HANDLE EXTENSION ARM
When an extension arm is installed, the bucket will hit the
boom cylinder foot and revolving frame when the arm is pulled
in, so be extremely careful during operations and when trans-
porting the machine.
(A): Range of prohibited use
• When an extension arm is installed, use a narrow bucket
(width: 750 mm, 560 mm without side cutters.
If the standard bucket is used, the stability is poor, and the
bucket will also hit the operator's cab when the arm is
pulled in, so do not install the standard bucket.
• For operations on hard soil or rock, do not use the exten-
sion arm. The service life of the extension arm, boom, and
arm will be reduced.
