Common operating errors of hydraulic breakers are as follows:

　　the

　　1. Do not use an incompatible breaker

　　Both the hammer and the excavator can cause serious damage if the hammer is too large for the excavator. So one should always match the size/weight of the hammer to the lifting capacity of the excavator.

　　2. Not using the correct settings

　　The operator must also set up the breaker and bracket for the specific application. For example, you may need to operate a circuit breaker when it is partially or fully submerged in water. In this case, are you running an underwater kit on your system? Subsea work requires a subsea kit and air compressor.

　　3. Putting the hammer in the wrong place

　　Operators need to know the proper placement of circuit breakers to minimize stress on accessories. The usual practice is to place the hammer in the center of the boulder or concrete. In this position, the hammer acts like a drill, not a hammer. The correct approach is to start from the corner and move inwards.

　　4. Don’t use the “scoring” method

　　When using circuit breakers, use what some call "scoring". Essentially, this means that each time you split a chunk, you move from one location to the next. Designed to reposition tool every 15 to 30 seconds.
