9.3.3 Operation Key Points of Hydraulic Breaker
(1) Cap the pipe end of arm and dismantle the hammer breaker
when not use.
(2) Install plugs for hose ends to prevent dirt.
(3) Store some spare caps and plugs for necessary use.
(4) Avoid dirt entering when changing the installation of bucket to
hammer breaker.
(5) After connection, check seal for oil leakage and bolts of tube
clamp for slack.
Before installing the hammer breaker to the arm, the operation manual of the excavator and the hammer
breaker should be read carefully. In addition, confirm or check as
required.
(1) Confirm and check as requirements before operation every
day.
(2) Operate the excavator slowly. Because the hammer breaker is
heavier than the bucket, that is the reason of the descending stability of the excavator. Thus, it should be
supported by mouldboard and the operation should be done in the front.
(3) Avoid using the hammer breaker for striking. Never use boom or
arm to break objects. If not, the excavator may be damaged.
(4) Don’t move objects with the hammer breaker, if failure to do
so, the excavator may be damaged.
(5) Don’t operate the hammer breaker when the hydraulic piston
rod is fully retracted or extended to avoid the damage of hydraulic
cylinder or the excavator.
(6) If there’s abnormal jump of hydraulic hoses of the hammer
breaker, stop the operation immediately. That’s caused by the
damaged accumulator, of which the pressure change of the hammer
breaker. More seriously, the hammer breaker and the excavator
may be damaged too.
