1. ExcavatorSilent breakerNeed to suspend work when the hose vibrates violently

Check whether the excavator breaker hammer pressure and the low pressure hose vibrate too violently. If this happens, it may be a malfunction, you should immediately contact your local office that has been approved by everyone to obtain after-sales maintenance services. It should be further checked whether there is oil leakage at the hose joint. If there is oil leakage, the joint should be tightened again. During the working period, it should be estimated whether the steel drill has a margin. If there is no margin, it must be stuck in the lower body. The lower body should be removed, and the parts should be repaired or replaced with faulty components.

2. Suspend work (to prevent too many air strikes)

If the stone is destroyed, the hammering should be suspended immediately. If the air strikes continuously, the anchor bolts will loose or break, and even the excavator and assembler will be badly affected. When the breaking hammer has an unreasonable penetration force or a broken hammer When the steel drill is used as a pry bar, it will cause an air strike. (The sound of the breaker will change when it strikes in the air strike)

3. The excavator hammer cannot be used to carry stones

It is not allowed to use the steel drill or the side of the support frame to flip or promote the stone. Because the steam pressure at the moment comes from the excavator, the upper arm and the forearm of the cutting machine. The actual operation of the bucket, swing or rolling, so the large and small arms will be destroyed At the same time, the anchor bolts of the breaker may be broken, the support frame will be destroyed, and the steel drill will be broken or scratched. It is necessary to prevent the use of a breaking hammer to carry the stone. In particular, the steel drill is inserted in the stone and must not be excavated. Able to move around.

4. Can not use steel drill as a crowbar

If the steel drill is used as a pry bar for sand and gravel, the anchor bolts and steel drill may break

5. The breaker of the excavator does not need to be higher than 1 minute when the hammer is constantly hitting south.

When hitting hard rock formations, the same hitting does not need to be higher than 1 minute, and then another hitting job. Long-term hitting will cause high oil temperature, which will cause the steel drill bushing to be destroyed and the steel drill to progress. damage.

6. For long, hard and large stones, crush them at the cracks or tails, so that they are relatively easy to crush the stones.

7. The breaker of the excavator should work at the regular engine speed

The breaking hammer is used for smashing, the engine speed ratio should meet the required fixed value, and the engine speed ratio higher than the work requirement will not increase the vibration force, but it will cause the high oil temperature to destroy the machinery and equipment.

8. The breaker of the excavator cannot work in water and mortar

It is not necessary to use the breaker in the water or in the mortar, otherwise, the piston rod or similar components may be corroded and cause damage. If you require underwater or underwater projects, you should especially order an underwater breaker.
