HYDRAULIC BREAKER (OPTIONAL)
Before installing a hydraulic breaker to the machine,
change in machine stability, and the hydraulic pressure
and flow rate to operate the hydraulic breaker must be
checked. Consult your nearest Hitachi dealer for
selection of the hydraulic breaker model to be installed.
Refer to the Breaker Operation Manual for operation of
the hydraulic breaker. Observe the following instructions
to prevent the base machine and the hydraulic breaker
from being damaged.
Precautions for Installing Hydraulic Breaker Pipe
Lines
•
When disconnecting or reconnecting the hydraulic
breaker hoses from or to the hydraulic pipe lines at the
arm tip, take care not to allow dust to stain or enter the
inside of pipes and hoses.
•
When the hydraulic breaker is not installed, be sure to
put caps or plugs to the arm tip pipe open ends and
the hydraulic breaker side hose ends to prevent the
hydraulic system from being contaminated by dust. Be
careful not to lose the caps and plugs. Always keep
the auxiliary parts in the tool box.
•
Check that the pipe clamp bolts are tight, and no oil is
leaking from the pipe and hose joints before operating
the hydraulic breaker.
Precautions for Hydraulic Breaker Operation
WARNING: When the hydraulic breaker is
installed, machine stability is reduced as the
breaker is much heavier than the bucket. In
addition, soil, broken pieces of rock or metals
may be scattered during breaker operation,
potentially creating hazardous situation. Take
protective measures against danger of machine
tipping over and/or scattering of hard materials
and observe the precautions described below to
ensure safe operation.
1. Avoid crashing the breaker onto hard materials.
The breaker is heavier than the bucket, causing the
lowering speed of the breaker to become faster. If
breaking hard materials by crashing the breaker onto
hard materials is attempted, damage to the front
attachment and/or the upperstructure may result due
to accelerated crashing reaction force.
2. Do not move crushed materials using the breaker unit
and/or the swing function. Damage to the boom, arm,
and/or breaker may result.
