ATTACHMENTS AND OPTIONS RECOMMENDED ATTACHMENT OPERATIONS
Do not let the machine come further off the ground than this
amount.
When the chisel does not penetrate or break the surface by
continuous impact to the same impact surface for 1 minute,
change the point of impact and perform breaking operations by
scraping from 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, always adjust the bucket cylinder to keep them aligned.
Always keep the chisel pressed against the impact surface
properly not to strike at the air.
