Setting the electronic impact power control dial
(fig. A)
• Turn the dial (3) 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. E.g.:
- 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 (fig. D)
The side handle (4) can be mounted on the front of
the machine to suit both RH- and LH-users.
Always operate the machine with the
side handle properly mounted.
• Unscrew the side handle clamp knob (7).
• Slide the side handle assembly onto the machine
locating the steel ring (8) in the mounting area (X).
• Adjust the side handle (4) to the desired angle.
• Slide and rotate the side handle to the desired
position.
• Lock the side handle in place by tightening the
clamp knob (7).
Instructions for use
• Always observe the safety instructions
and applicable regulations.
• Be aware of the location of pipework and
wiring.
• Apply a pressure of approx. 20 - 30 kg
to the tool. Excessive force does not
speed up chiselling but decreases tool
performance and may shorten tool life.
Switching on and off (fig. A)
• Switching on: set the on/off switch (1) to position 1.
• Switching off: set the on/off switch (1) to position 0.
Demolition, chasing and channelling (fig. A)
