HANDLING EXTENSION ARM
HANDLING EXTENSION ARM:PC-L850-170K00A
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.
q
When an extension arm is installed, use a narrow bucket
(width: 750 mm with side cutters, 560 mm without side cut-
ters). 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.
q
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.
