Bucket Types and Applications

ZX350LC(N)-7
IMPORTANT:
 When digging on a solid ground with the super
long front attachment, the front attachment may be
damaged.
 Use the super long front attachment for digging of
soft ground.
 If a wide-size bucket other than recommended
is used for operation, it may result in a front
attachment twist and damage to the parts.
 Ensure the total weight of the bucket and material
load does not exceed the maximum allowable
loading weight of the machine when operating the
machine.
The maximum allowable weight is determined by
Hitachi standards. If the total load exceeds this value,
it may cause machine turnover or damage on the
front attachment. Select a bucket having capacity
and weight with maximum allowable loading weight.
 If a bucket with a larger radius than recommended is
used, the bucket cylinder has the possibility to relief
depending on ground condition.
Use a bucket in combination shown in the below table
when the super long front attachment is installed. If a mass
excavation bucket or an extreme service excavation bucket
which is not described in the table is used, the machine
stability will not be secured and the strong force may be
applied to the main body, front attachment and cylinders,
resulting in damage on the machine.
Use the bucket and the arm in combination only as described
in the below table.
