ARRANGEMENT FOR THE INSTALLATION OF THE DEMOLITION HAMMER
6.6.2 USE OF THE DEMOLITION HAMMER AND RULES TO BE OBSERVED
FOR A CORRECT USE OF THE HAMMER, IT IS
NECESSARY TO:
The choice of the suitable tool is a very important factor to obtain the maximum productivity from the demolition
hammer.
The shape and size of the tool must be defined according to the nature of the material to be broken and to the
type of work to be carried out.
The hammer is used to break floors, cement structures, walls, small rocky surfaces, excavations with open sec-
tion, aspahlt, etc.
With the application of special tools it can also be used as asphalt-cutter or compactor.
1 - Make sure that the position of the hammer with respect to the
material to be broken is as perpendicular as possible and
that the arm thrust is sufficient, so that all the power of the
hammer can be exploited.
2 - Keep the pressure of the excavator on the hammer constant
as the bit penetrates in the material.
Always follow the hammer while it penetrates and operate
the excavator arms in order to obtain a pressure sufficient to
keep the undercarriage raised at approximately 5 cm from
the ground.
Do not raise the rear wheels 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
very frequently, in such a way as to facilitate the breaking of
the material.
