the arrow ( ) of the selecting button
(6) into the position ( ) and rotate
the chisel position regulator (4) until
the accessory is in the desired position.
When rotating the selecting button to
set the operating mode, the chisel gets
blocked.
4.4 - ROTATION SPEED
AND IMPACT FREQUENCY
REGULATION (FIG. H)
The hammer is equipped with an
electronic controlling device that
allows preselecting the rotation speed
and impact frequency according to
the material and type of work. This
control device keeps the preselected
impact frequency and the rotation
speed almost constant in charge or idle
conditions.
The rotation speed and impact
frequency can be adjusted, from 1 to
6, on the impact frequency regulating
button (14);
1. To increase the rotation speed and
impact frequency, rotate the regulating
button to the right;
2. To decrease de rotating speed and
impact frequency, rotate the regulating
button to the left;
In the following panel are shown the
minimum and maximum values to
rotation speed and impact frequency.

Never adjust the rotation speed
and the impact frequency when
operating the hammer. To perform any
adjustment, stop the equipment.
4.5 - STATE INDICATOR LIGHTS
(FIG. I)
The green indicator light (15), which
represents the power supply, activates
when the hammer is connected to the
power source.
The red indicator light (16), which
represents the carbon brushes,
activates when the brushes are worn,
indicating the necessity of replacement.
4.6 - VIBRATION REDUCTION
SYSTEM
The hammer is equipped with an active
vibration reduction system (6) that
absorbs vibration without detriment
to the machine’s performance. This
system reduces meaningfully the
exposure level throughout the entire
operation, protecting its user from the
vibration effects.
5. MAINTENANCE
AND CLEANING
INSTRUCTIONS
Make sure the hammer is disconnected
from the main supply before carrying
any maintenance or cleaning work.
