6.2 ARRANGEMENT FOR THE INSTALLATION OF THE DEMOLI-
TION HAMMER (BREAKER)
DANGER
For the characteristics of the hammer, see "6.1.3 CHARACTERISTICS OF THE OPTIONAL EQUIP-
MENT".
The demolition hammer is very noisy, therefore always wear headphones when using it.

6.2.1 DESCRIPTION AND CONTROL

The machine is fitted for the application of a demolition hammer;
the operation of the hammer is obtained by means of an addi-
tional distributor controlled by a pedal (1) positioned on the left
side.
The hammer is operated by pressing the pedal (1) with the toe,
since pressurized oil is thus introduced in the delivery circuit (left
side); the oil flow is interrupted and the hammer is thus stopped
by releasing the pedal.
To use the demolition hammer, make sure that the control of the
selection valve (2) is completely rotated anticlockwise (Pos. A).

6.2.2 USE OF THE DEMOLITION HAMMER AND RULES TO BE OBSERVED

The choice of the suitable tool is a very important factor to obtain the maximum productivity from the demolition
hammer.
The geometry 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, asphalt, etc. With the application of special tools it can also be used as asphalt-cutter or compactor.
FOR A CORRECT USE, IT IS NECESSARY TO:
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.
