Conversely, when the operation is insufficient, the striking force will not be fully exerted; at the same time, the striking force of the breaker will shock back to the breaker body, the guard plate and the operating arm of the construction machine itself, resulting in damage to the above-mentioned parts. Not only delays the construction period, but also easily breaks the breaker.

1. Check and maintain the machine before use

Before the breaker is constructed, it needs to be checked around the car. The first step is to check whether the high pressure and bottom pressure plastic hoses of the broken hammer are loose, and whether there are leaks in other areas. In addition, regularly check the nitrogen pressure inside the breaker.

2. Vertical hit

Before the breaker works, place the steel drill vertically on the broken object, confirm that the steel drill is stable, and then turn on the breaker. During the crushing operation, it is also necessary to ensure that the steel drill is perpendicular to the object to be hit; if it is inclined to the hitting surface, the steel drill may slip off, which will damage the steel drill and piston of the breaker.

3. Airplay is strictly prohibited

Avoid letting the breaker hit without a target. When the rock or target has been broken, please stop the striking action of the breaker immediately. The continuous impact without target will only cause loosening and damage to the screws of the front body and the main body, and even damage the construction machinery body. In the case of aimless strikes, in addition to improper insertion, shaking the breaker will also have an impact.

4. Do not push heavy objects or large rocks with a breaker

Do not use the guard plate as a tool to push heavy objects when working, so it will only cause the guard plate screws, drill rods to break, damage the breaker, and even the main reason for the boom to break.

5. Do not use the drill rod to shake

During the crushing operation, if you try to shake the drill rod, the main screw and the drill rod may be broken.

6. Do not break the work in water

The breaker is not a closed structure, it cannot be immersed in water at ordinary times, it is easy to damage the piston cylinder and pollute the hydraulic oil circuit of the excavator. So try not to work in rainy days and water; in special cases, except for the steel brazing, other parts cannot be immersed in water.

7. The attack time should not be too long

When hitting the same point continuously for more than one minute and failing to destroy the target, please change the selected point of the attack and try again. Trying to keep hitting at the same point will only cause excessive wear of the drill rod.

8. Do not operate when the hydraulic cylinder of the construction machinery body is fully extended or fully retracted.

When the hydraulic cylinder of the construction machinery body is fully extended or fully retracted, if the striking operation is carried out, the striking vibration will bounce back to the hydraulic cylinder body and cause serious damage to the construction machinery.
