Operation
This power tool is supplied from single-phase alternat-
ing current mains only. It is double insulated according
to EN 60745-1 and can be connected to grounded or not
grounded sockets. This power tool is radio suppressed in
compliance with EMC Directive 2004/108/EC.
This power tool is designed for chiselling, chipping and
demolishing concrete, rocks and asphalt with high effi-
ciency.
PRIOR TO INITIAL OPERATION
▪
Always check the position of ON/OFF switch. The
power tool must be connected to the power supply
socket only when this switch is in OFF position. If the
plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, which could cause a serious
accident.
▪
Make sure the cord and the plug are in order. If the
replacement of the supply cord is necessary, this has
to be done by the manufacturer or his agent in order
to avoid a safety hazard.
▪
Switch off and unplug the machine prior to any pro-
cedure on the power tool or in case of mains drop
out.
▪
In case of work area remote from the power source,
use as short as practicable extension cord with prop-
er cross-section.
▪
Make sure the auxiliary handle is properly mounted
and securely fastened.
INSTALLING AND REMOVING BITS
WARNING: Switch off and unplug the ma-

EN
2. Pull the tool retainer lever (2) toward yourself.
3. Rotate 180° the tool retainer lever (2) while pulling it.
4. Next, insert the tool shank into the hexagonal tool
holder (1) on the front cover (3).
5. Clamp the tool by turning the tool retainer (2) by rotat-
ing it at 180° in the opposite direction (Fig. 2).
To remove the bit, follow the above described proce-
dures in reverse order.
SWITCHING ON - SWITCHING OFF (Fig. 3)
Switching on: Depress and hold button (8) and then
press the ON/OFF switch (9).
Switching off: Release ON/OFF switch (9).
WARNING: Before plugging in the tool, al-
ways check to see that the trigger switch (6) actuates
properly and returns to OFF position when released.
OPERATING THE BREAKER
▪ Insert the plug into the socket.
▪ Apply the tool tip at 80–100 mm from the edge of the
material to be processed and press the trigger switch
(9).
▪ Start operating at 70°–80° to the surface and guide
the tool tip to the edge. Then change the angle to 90°
and break the processed material.
▪ Operate the machine by utilizing its empty weight to
achieve optimum performance. Insufficient force shall
cause tool rebound. Too high pressure against the
surface shall decrease efficiency.
In some cases, it is necessary to punch the tool tip
against the crushing position forcibly in order to actuate
the striking motion. This is not due to malfunction of the
tool. It means that the safeguard mechanism against no-
load striking is working.
WARNING: Sometimes the striking motion
does not start even when the motor rotates because
the grease has become thick. If the demolition ham-
mer is operated at low ambient temperature or after
storage, let the machine run for five minutes in order
to warm up.
▪ Turn the tool at regular intervals to achieve uniform
wear and aid self-sharpening.
