2-12. OPERATION OF HYDRAULIC BREAKER
⚫
The hydraulic breaker is an attachment to the hydraulic excavator. Follow the instruction
manual for the hydraulic excavator when starting the machine.
⚫
Set up the excavator to operate the hydraulic breaker. If there is a “Hydraulic Breaker
Mode” on the excavator, change to the mode. Position the throttle of the excavator
(engine RPM) at the mark for the hydraulic breaker.
Then, follow the excavator manual for operation.
⚫
Place the breaker against the object at a
90-degree angle.
⚫
When operating the breaker, raise the chisel
against the object and the front portion of
the excavator about 5 cm (2 inch) from the
ground.

⚫
When operating the hydraulic breaker, ensure to use the piping for the hydraulic breaker.
⚫
If there is a ”Hydraulic Breaker Mode” on the excavator, change to the mode.
⚫
If a piping of the excavator is set up for the hydraulic crusher, 1) the excessive hydraulic
oil might be supplied to the hydraulic breaker. 2) Wrong pedaling creates the high pressure
to the low pressure piping of the hydraulic breaker. In both cases, it could cause damage
to the hydraulic breaker.
CAUTION
When the angle is not 90 degree, the breaker will
be slipped. It cause the chisel breakage, seizure of
bush. Choose stable surface to beating. Avoid
any excessive force.
CAUTION
When pushing force is not enough, it will lead
blank blows. Blank blows will give a big impact to
the breaker and excavator, and cause serious
damage and the breakdown.
CAUTION
CAUTION
Ensure that the front part of the excavator is not raised too high.
After the material is broken, take caution since the balance of the excavator becomes unstable.
