PRIOR TO INITIAL OPERATION
▪ Make sure the power supply voltage corre-
sponds to the value indicated on the name
plate with technical data of the tool.
▪ 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 operat-
ing immediately, which could cause a serious
accident.
▪ Make sure that the cord and the plug are in
order. If the replacement of the supply cord is
necessary, this has to be done by the manu-
facturer or his agent in order to avoid a safety
hazard.
WARNING: Always switch off and un-
plug the power tool prior to any adjustment,
servicing or maintenance.
▪ In case the work area is remote from the pow-
er source, use as short as practicable exten-
sion cord with proper cross-section.
▪ Check that the auxiliary handle is properly
mounted and reliably tightened.

SWITCHING ON - SWITCHING OFF
Brief activation:
Switching on: Press ON/OFF switch 6. (Fig.1)
Switching off: Release ON/OFF switch 6.
Continuous operation:
Switching on: Press ON/OFF switch 6 and in
pressed position lock it by button 7. (Fig. 2)

INSERTING OF SDS-PLUS TOOL
Clean and grease the shank of the accessory,
before placing it into the socket! (Fig.3)
Pull backward the sleeve 2 of the socket 1
(Fig. 4a) and insert the SDS-Plus bit until stop.
Ensure that the socket grooves correspond to
the shank channels, and then release the sleeve
to fix the bit. (Fig. 4b)
To remove the bit, pull the sleeve 2 back, and
then take the bit out. (Fig.5)

overloading the power tool..
SELECTING THE SPEED, FREQUENCY
AND IMPACT ENERGY
Rotate the regulator 8 to choose a position
appropriate for the processed material. The
constant electronics maintain the speed, the
frequency and the impact energy constant, in-
dependently of the load, thus ensuring steady
operation mode. It is recommended to use the
operation modes listed in the table.

Rotate the regulator 8 from position A to position
F to increase the speed, the frequency and the
impact energy. The indicator 9 shall blink with
green light.
To choose HIGH POWER mode, rotate the reg-
ulator 8 to position G. This mode is distinguished
w increased impact energy up to 6J. The indica-
tor 9 shall glow with constant green light.
SELECTING THE OPERATION MODE
The switching of operation modes can be per-
formed when the machine is not operating.
Rotate the operation mode switch 5 in the direc-
tion marked on the switch to the desired position
