OPERATING THE MACHINE PRECAUTIONS FOR BREAKER OPERATION WARNING: Machine stability is reduced as the breaker is much heavier than the bucket. When using a breaker, the machine is more apt to tip over. Also, flying objects may hit the cab or other part of the machine. Observe the following precautions and take any other precautions necessary to prevent accidents and machine damage from occurring. WRONG • Avoid hitting objects with breaker. The breaker is heavier than the bucket, causing the break- er to lower faster. Take care not to hit any objects with breaker. Doing so will result in damage to the breaker, the front attach- ment, and/or the upperstructure.
Always move (lower) the breaker slowly to position the tip of the chisel on the object to be broken before starting breaker operation.
