If the disruptive force is insufficient, the hammering energy of the piston cannot effectively break the rocks. The
reactive force of such hammering force would be transmitted to the Breaker body, the boom and arm of the
excavator, etc. and damage such parts.
If the disruptive force is excessively high, and the breaking operation is made, the machine would be tilted at the
moment of breaking the rock. The severe impacting of the breaking hammer against the rock would damage the
Breaker. In addition, striking under such conditions would also transmit the vibrations in a way that could damage
the excavator tracks.
3. The disruption point should be properly selected during the breaking operation to guarantee stable striking of the steel
rod. Operate the Breaker’s steel rod in the vertical position as possible.
If the hammering direction is tilted, the steel rod could escape from the Driver during the striking operation,
causing breakage or jamming of the steel rod and piston
4. The following precautions should be followed by the operating personnel during the operation of the Breaker:
4.1. The operation should be stopped under strenuous vibration of the hose.
Excessive vibration of the hoses can lead to failure of the accumulator or oil leakage at hose joints. Stay vigilant
during operation, and mitigate these issues.
4.2. Stop hammering immediately after the rocks are crushed. The operation should be suspended to avoid
excessive empty striking.
Continuous empty striking could damage the accumulator; break the bolts, flat pins and front head, harm the
steel rod, and even adversely affect the excavator.
4.3. Do not use the Breaker to roll or push the rocks.
Using the steel rod or the sides of the bracket to move rocks could damage the boom and/or arm of the excavator.
Using the Breaker in this way could also fracture the bolts of the Breaker, damage the bracket, and fracture or
scratch the steel rod. It should be particularly noted that, if the steel rod is inserted into the rock, do not make
the excavator travel.
4.4. Do not use the steel rod as a pry bar.
If the steel rod is used as a pry bar during the breaking operation, the bolts and the steel rod could be fractured.
4.5. Do not operate the Breaker under continuous striking for longer than one minute.
Long time striking would rise the oil temperature and further damage the accumulator or cause excessive
abrasion of the steel rod. Where hard rocks are to be crushed, change to another location for striking after one
minute.
4.6. For relatively long, hard, or large rocks, it is recommended to start crushing at the cracks or rear end and
breaking the rock in multiple locations until completion.
4.7. The Breaker should be operated under the appropriate engine speed.
Engine speed exceeding the operation requirements would not increase the striking force. Instead, it would
increase the oil temperature and further damage the equipment.
4.8. Do not operate the Breaker in water or mud.
