Find the Proper Position of the Tool When Doing Work

Proper position of the tool

Proper position must be applied for an effective use of breaking fore. When position is incorrect, blowing energy of the position is too weak to break rocks. Instead, blowing force applies shocks to the breaker body, breaker, arm and boom of the base machine, thereby resulting in damage to those parts.

On the contray, when position is excessive enough to break rocks with front of the base machine raised, the machine may suddenly tilt forward the moment rocks are broken then the  breaker body or the end of bracket may violently hit against rocks and result in damage.

It is undesirable to carry out hammering under the below condition, because vibrations during hammering may be transmitted to tracks of the base machine. During hammering, however, proper position must be always applied to the breaker. Special care must be taken out to hammer under abnormal condition.
