Setting the Electronic Impact Power
Control Dial (fi g. 1)
Turn the dial (c) to the desired level. The higher the
number, the greater the impact energy. With dial
settings from «1» (low) to «7» (full power) the tool is
extremely versatile and adaptable for many different
applications.
The required setting is a matter of experience,
for example:
• when chiselling soft, brittle materials or when
minimum break-out is required, set the dial to
«1» or «2» (low);
• when breaking harder materials, set the dial to
«7» (full power).

machine with the side handle properly
mounted.

2. Slide the side handle assembly onto the
machine locating the steel ring (h) in the
mounting area (x). The correct position of the

3. Adjust the side handle (f) to the desired angle.
4. Slide and rotate the side handle to the desired
position.
5. Lock the side handle in place by tightening the
