OPTIONS, ATTACHMENTS
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 opera-
tions 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 prop-
erly to prevent using the impact force when there is no resistance.
