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).
Fitting and Adjusting the Side Handle
(fi g. 6)
The side handle (f) can be mounted on the front of
the machine to suit both RH- and LH-users.
WARNING: Always operate the
machine with the side handle properly
mounted.
1. Unscrew the side handle clamp knob (i).
2. Slide the side handle assembly onto the
machine locating the steel ring (h) in the
mounting area (x). The correct position of the
side handle is between head and middle of the
tube.
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
clamp knob (i).

speed up chiselling but decreases tool
performance and may shorten tool life.

serious personal injury, ALWAYS use
proper hand position as shown.
WARNING: To reduce the risk of
serious personal injury, ALWAYS hold
