ARRANGEMENT FOR THE INSTALLATION OF THE DEMOLITION HAMMER (BREAKER)
2 - Keep the pressure of the excavator on the hammer constant
as the bit penetrates in the material.
Always follow the hammer in the penetration phase and oper-
ate the excavator arms in order to obtain a pressure sufficient
to keep the undercarriage raised at about 5 mm from the
ground.
Do not raise the undercarriage more than necessary.
3 - When working on very hard materials, it is important not to
keep hitting the same point for more than 30 seconds.
Hit the same point for a few seconds and change position
very frequently, in order to facilitate the breaking of the mate-
rial.
4 - To facilitate the sliding of the tool on its seat, check the thrust
direction and always correct the hitting position of the ham-
mer by means of the bucket and arm control.
5 - Always check that the arm thrust is optimal, in order to avoid
harmful and useless strokes.
