When applying continuous impact to the same surface, if the chisel does
not penetrate or break the surface within 1 minute, change the point of
impact and carry out breaking operations 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 other, 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 resistance.
