Balance the load when picking it up to prevent twisting
the boom assembly and linkage. When dumping
awkward loads, dump slowly to reduce the shock of
weight transfer to the rear axle when the bucket is
emptied.
Improper Uses of the Multipurpose
Bucket
Equipment Operators have created techniques to
perform a variety of construction operations using
loaders equipped with the multipurpose (4-in-1) bucket.
However, these techniques can cause UNNECES-
SARY DAMAGE to multipurpose (4-in-1) buckets by
subjecting them to conditions they were not designed
for. Some of the ways a multipurpose bucket should
NOT be used are as follows:
Do NOT use the rollback as a force to pull stumps
or buried objects from the ground, because this may
bend the clamshell (fig. 9-28).
Do NOT attempt to break off buried or anchored
objects with the clamshell by back dragging, because
this may bend the clamshell (fig. 9-29).
Do NOT attempt to break off buried or anchored
objects by side loading the clamshell, especially when
opened, because this may bend the sides of the clamshell
(fig. 9-30).
