1. It should be stopped when there is a violent vibration in the hydraulic breacker’s hoses.

The excavator breaker high pressure and low pressure hoses should be checked for excessive vibration. If this is the case, there may be a fault and you should contact your local approved service office immediately for repair. The hose joints should be further checked for oil seepage, and if so, the joints should be retightened. If there is no spare capacity, it must be stuck in the lower body, and the lower body should be removed to see if the parts should be repaired or replaced.

2. Stop working (avoid excessive air strikes)

Once the stone is broken, the hammering should be stopped immediately. If the hammering continues, the bolts will loosen or break, and even the excavator and loader will be adversely affected. When the hydraulic hammer penetration force is not appropriate or when the steel braze used as a pry bar, will produce empty striking phenomenon. (The sound will change when the hammer strikes when the hammer is empty)

3. Excavator crusher hammer can not be used to move rocks

Do not use the end of the brazier or the side of the bracket to roll or push the stone. Because the oil pressure comes from the excavator, loader big arm, small arm. Bucket, swing or slide operation, so the large and small arms will be damaged, while the hammer bolt may break, the bracket will be damaged, the braze will break or scratch, should avoid using the hammer to move the stone. In particular, the steel braze inserted in the stone, digging must not walk.

4. Do not use the steel drill as a pry bar

If you use the brazier as a pry bar when crushing stone, the bolt and the brazier may break.

5. Excavator hydraulic hammer continue to hit do not exceed one minute

When hitting hard rocks, do not hit the same place for more than one minute and then change the hitting operation. Prolonged striking operation will cause the oil temperature to rise, which will lead to damage to the bushings and wear on the progress of the drill.

6. For long, hard boulders, can start to break at its crack or end, so that it is relatively easy to break the stone

7. Excavator crusher should operate at routine engine speed

hydraulic hammer for crushing is the engine speed should be in line with the specified fixed value, more than the engine speed required for the operation will not increase the striking force, but will make the oil temperature rise, resulting in equipment damage.

8. Excavator hammer can not work in the water and mud

Do not use the hammer in water or mud, otherwise the piston or similar parts may rust and cause sexual damage. If you need to work in water or underwater, you should special order a submersible type hammer.
