When applying impact, push the chisel against the impact sur-
q
face and operate so that the chassis rises approximately 5 cm
off the ground. Do not let the machine come further off the
ground than this amount.
When applying continuous impact to the same impact surface, if
q
the chisel does not penetrate or break the surface within 1 min-
ute, 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
q
breaker body will gradually move out of line with each other, al-
ways adjust the bucket cylinder to keep them aligned.
Always keep the chisel pressed against the impact surface
q
properly to prevent using the impact force when there is no re-
sistance.
