When opening, be careful not to punch the cavity and do not pry the stone when the drill rod is opened.

Correct operation can improve the working efficiency of the breaker and prolong the service life of the breaker. The precautions for operation are as follows;
1) Before each use, check whether the high and low pressure oil pipe of the breaker has oil leakage and looseness. In addition, it is necessary to check whether there is oil leakage in other places at any time to avoid failure due to vibration causing the oil pipe to fall off.
2) The drill rod should always be in a perpendicular state to the surface of the stone during the crushing hammer operation, and the drill rod should be compacted, and the crushing should be stopped immediately after crushing to prevent empty hitting. If the continuous and aimless impact will cause damage to the precursor of the breaker and loosen the main body bolts, and in severe cases, it can injure the main engine itself.
3) Do not shake the drill rod when crushing operation, otherwise the bolt and the drill rod may break.
4) It is strictly forbidden for the breaker to work in water or mud. Except for the drill rod, the former sheath of the breaker should not be flooded in water or mud.
5) When the crushed object is a large hard object (stone), please choose to crush from the edge, no matter how large and hard the stone is, it is usually more feasible to choose to start from the edge, and the same fixed point is continuously hit for more than one minute and cannot be broken. Please change the selected point of the blow and try again.
6) When the construction machinery cylinder is fully extended or fully contracted for striking operation, the shock vibration will be returned to the cylinder body, resulting in damage to the construction machinery.
7) Do not use the side plate as the surface to push the heavy object when working, so it will cause damage to the side plate bolts and drill rods, and will damage the breaker, and even break the boom. In order to make the breaker better play the efficiency and prolong the service life, it should be cautious in maintenance and use.
Generally, if the operation manual is violated, the manufacturer will not give compensation. Wish.

Many excavators do not have a breaker control switch, if the solenoid valve is used to control the breaker, then the control switch is on the right armrest box; Some use buttons on the left and right joysticks; Most breakers are controlled by the foot valve next to the right-hand walking foot valve, and the key depends on how your breaker fits the pilot pipe.

Regarding the switch of the breaker, it is as follows:
If the solenoid valve is used to control the breaker, then, the control switch is on the right armrest box, and some use the buttons on the left and right levers, most of the breaker is controlled by the foot valve next to the right walking foot valve, the key depends on how your breaker is installed with the pilot pipe.

The selection of breaker generally needs to consider the following aspects:
1. The weight and bucket capacity of the excavator fully consider the weight of the excavator, which can prevent the excavator from tipping over due to the excessive weight of the breaker when the boom is fully extended. The optional breaker is too large and may cause the excavator to tipple, too small and can not give full play to the excavator's effect, and will also accelerate the damage of the breaker. Only when the weight of the excavator and the breaker match can the excavator and breaker be fully utilized.
In general, the excavator's standard bucket volume reflects the weight of the machine. At present, the best method is to calculate the range of optional breakers according to the bucket capacity of the excavator.
The bucket capacity and the weight of the hammer are related as follows: wh=(
Where: wh=wl+w2+w3w1 hydraulic hammer hammer body (bare hammer) weight w2 chisel weight w3 hydraulic hammer frame weight w4 excavator bucket weight sand density, generally =l600n m3v excavator bucket capacity.
2. The working flow of the hydraulic breaker and the working flow of the hydraulic breaker with different pressures are different. The flow rate of a small hydraulic breaker can be as small as 23 liters per minute, while a large hydraulic breaker can reach more than 400 liters per minute. When selecting a hydraulic breaker, it is necessary to make the flow requirements of the hydraulic breaker consistent with the output flow rate of the excavator backup valve.
Generally speaking, the flow rate determines the working frequency of the hydraulic breaker, that is, the number of impacts per minute, and the flow rate is proportional to the number of impacts. However, when the output flow of the excavator backup valve is greater than the required flow rate of the hydraulic breaker, the hydraulic system will generate too much heat, resulting in too high system temperature and reducing the service life of the components. When the hydraulic hammer is selected, the working pressure of the hydraulic breaker should be consistent with the limited pressure of the backup valve.
If it does not match, a relief valve should be added to the pipeline system and adjusted according to the rated pressure of the hydraulic hammer.
3. The structure of the hydraulic breaker is vehicle-mounted, and the hydraulic breaker currently has three most common appearance designs, namely triangle type, splint type and box type (also called silent type).
Triangle type and splint type is usually used to protect both sides of the hammer core with two thick steel splints, such a structural design has no protection for the front and back of the hydraulic breaker, their disadvantage is that it is more noisy than the box-type hydraulic breaker of the same tonnage, the steel plate on both sides is easy to loosen or crack, and the protection of the hammer body is not good, this kind of structure has been rare in the European and American markets.
The structure of the box-type hydraulic breaker is that the shell completely encloses the hammer body, and the shell is equipped with vibration damping material, which can reduce the vibration of the carrier while creating a buffer between the hammer body and the shell. The advantages of box-type hydraulic breaker are that it can provide better protection for the hammer body when working, low noise, reduce vibration to the carrier, and also solve the problem of loose shell, which is also the mainstream and development trend of the global market.
As a general user, it is necessary to choose the most suitable hydraulic breaker according to the comprehensive consideration of many aspects, so you should carefully read the instruction manual of the excavator before the selection, or consult the excavator manufacturer, breaker manufacturer and distributor for relevant technical consultation.

Hitting a hammer is more harmful to the car than digging the soil, mainly because the liquid residual silver pressure pump is easy to break. This is not a problem of improper operation, it is determined by the principle of working and erecting the hammer. There is nothing special to pay attention to in terms of maintenance, and the grease is checked to see if the hammer is leaking, which is basically the same as the excavator.
It's easy! Just step on it, and some are buttons on the handle. But pay attention to the rhythm, don't play the spare orange hammer.
If you don't have experience in a three-story house, it's better not to demolish it, it's very dangerous. Good luck!

Install a protective device in the cab, otherwise it is easy to be hit by flying stones!!

Is there dust silicosis?
There is also a lot of vibration and noise pollution, which is harmful to the human body.
