RECOMMENDED ATTACHMENT OPERATIONS When applying continuous impact to the same impact surface, if the chisel does not penetrate or break the surface within 1 minute, change the point of impact and carry out breaking op- erations closer to the edge. The direction of penetration of the chisel and the direction of the breaker body will gradually move out of line with each oth- er, so always adjust the bucket cylinder to keep them aligned. Always keep the chisel pressed against the impact surface properly to prevent using the impact force when there is no re- sistance.
