Crusher Operation (Optional) - Hitachi ZAXIS 17U-2 Operator's Manual

CRUSHER OPERATION (OPTIONAL)

Before installing a hydraulic crusher on the machine,
machine stability, and the hydraulic pressure and flow
rate to operate the hydraulic crusher must be checked.
Consult your nearest Hitachi dealer for selection of the
hydraulic crusher model to be installed. Refer to the
Crusher Operation Manual for operation of the hydraulic
crusher. Observe the following instructions to prevent
the base machine and the hydraulic crusher from being
damaged.
Precautions for Hydraulic Crusher Operation
WARNING: When the hydraulic crusher is used in
demolition work, machine stability is reduced as
the crusher attachment is much heavier than the
bucket. In addition, soil, broken pieces of rock or
metals may be scattered during crusher
operation, potentially creating hazardous
situation. Take protective measures to prevent
machine tipping over and/or scattering of hard
materials and observe the precautions described
below to ensure safe operation.
•
Do not raise the base machine off the ground with the
bucket cylinder fully retracted or extended. Damage to
the front attachment may result. In particular, avoid
operating the machine with the bucket cylinder fully
extended. The bucket cylinder may easily become
damaged under this condition. Use extra care to
prevent the bucket cylinder from being damaged
during demolition work of structure foundations.
•
Operate the crusher over the front or rear side of the
machine. Operating the breaker over the side of the
machine will reduce the machine stability, possibly
resulting in tipping over of the machine.
