2. It is absolutely necessary to keep the pressure of the
excavator on the breaker constant as the bit penetrates the
ground.
Always accompany the breaker as it penetrates and use
the excavator arms to obtain such a pressure as to keep
the undercarriage lifted approx. 5 cm from the ground.
Avoid lifting the undercarriage more than necessary.
3. When working on very hard materials it is important to
avoid hitting the same point for more than 30 seconds.
Hit the same point for a few seconds and change position
continuously: in this way the material breaks more easily.
4. To facilitate the free sliding of the tool on its seat, check the
thrust direction correcting always the stop position of the
demolition hammer on the bucket control and the 2nd
boom.
5. Always make sure that the thrust is optimal, in order to
avoid dangerous and useless strokes.
