The chisel may be deformed or broken. Grind the deformed part or replace the chisel. This problem often occurs when the chisel is deformed or broken. During operation, continuous impact or improper positioning may cause the chisel to bend or fold, making it difficult to fit into the breaker. In such cases, the damaged area should be carefully ground to restore its shape, or the chisel should be replaced with a new one to ensure proper alignment. Using a damaged chisel may also cause further harm to the breaker components and reduce striking efficiency, so timely inspection and maintenance are essential before continuing work.

When the object being broken is too small, the excavator cannot maintain stable support on the ground, leading to unstable striking conditions. To solve this, make sure the excavator is parked securely on level ground and the object is fixed firmly in place before starting to strike. If it remains difficult to stabilize the chisel, reduce the nitrogen pressure in the back head, which allows a higher impact rate and improves overall efficiency. Stability and proper adjustment of nitrogen pressure are crucial to avoid equipment damage and achieve smoother breaking performance.

If the breaker continues to perform poorly after adjustments, there may be issues with the back head pressure or the hydraulic system. Excessive nitrogen pressure or low hydraulic oil temperature can reduce the impact force and slow down operation. Always warm up the hydraulic oil before use in cold weather and ensure the pressure is within the manufacturer’s standard range. Additionally, high back pressure in the return oil pipe can cause inefficiency. If these conditions persist, contact an authorized Beilite agent for professional inspection and assistance to prevent potential damage.

The chisel may fail to operate properly due to several causes, including an internal malfunction of the hammer, unstable hydraulic pressure in the excavator, or excessively high nitrogen pressure in the back head block. Internal mechanical faults or irregular hydraulic pressure can lead to inconsistent impact force and reduced performance of the breaker. In such situations, it is strongly recommended to contact a certified Beilite agent for professional inspection and repair to avoid further equipment damage. Additionally, if the nitrogen pressure in the back head is found to be too high, it should be adjusted to the manufacturer’s specified standard range under expert guidance to restore normal operation and ensure stable, efficient performance.

When there is sufficient high pressure on the breaker’s high-pressure side but the breaker still fails to operate normally, several potential causes should be considered. The issue may result from a blockage in the hydraulic circuit, an internal malfunction within the breaker, or impurities entering the hydraulic system—all of which can disrupt pressure flow and reduce performance. Back pressure forming at the oil return nozzle can also hinder operation. In these cases, it is recommended to contact a certified Beilite agent for technical inspection and repair. Additionally, a blocked excavator filter may restrict hydraulic flow; cleaning or replacing the filter can resolve this. If the nitrogen pressure in the back head is too low, it should be checked and adjusted to the standard range. However, if the same issue persists even after recharging the nitrogen, professional assistance from a Beilite agent is necessary to prevent further damage and ensure stable operation.

Yes. Excessive nitrogen pressure can prevent the chisel from operating correctly. Solution: Check the back head pressure and adjust it to the manufacturer’s standard range.
