Operation

This power tool is supplied from single-phase alternating
current mains only. It is double insulated according to EN
60745, IEC 60745 and can be connected to grounded
or not grounded sockets. This power tool is radio sup-
pressed in compliance with EMC Directive 2004/108/ E C.
This power tool is designed for impact drilling in steel,
wood, plastics, etc. The provided impact-rotary opera-
tion mode ensures drilling openings in concrete, stone,
masonry and various brittle materials.
PRIOR TO INITIAL OPERATION
WARNING: Make sure the power supply volt-
age corresponds to the value indicated on the name
plate with technical data of the appliance.
▪ 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.
▪ Check whether the auxiliary handle is properly
mounted and fastened securely.
WARNING: Prior to operation always check
the direction of rotation. Shift the reversing switch
only when the spindle has come to a complete stop.
Reversing prior to final spindle halt may damage the
power tool.
INSERTING AND FASTENING DRILL BITS
WARNING: Switch off and unplug the ma-
chine prior to any procedure on the power tool.
For keyed chuck drills:
Through turning the collar of the chuck (2) clockwise
or anti-clockwise the jaws are positioned so the drill bit
shank can be inserted inside the choke. By turning the
collar of chuck (2) clockwise the jaws tighten the drill bit
shank. Fix the drill bit finally in the chuck by means of the
special chuck key, tightening equally in all three bores.
For keyless-chuck drills:
To unlock the chuck, pull its rear collar towards the tool
until it clicks (Fig. B).
Grip rear collar of keyless chuck and rotate front collar

EN
until chuck is opened sufficiently for the bit to be inserted.
Then firmly tighten front collar by hand.
After the drill bit has been placed in the chuck, the chuck
must be locked to prevent the bit from slipping. To lock
the chuck, pull its rear collar towards the drill bit (Fig. C).
SWITCHING ON - SWITCHING OFF
Brief activation:
▪ Switching on: Press ON/OFF switch (11).
▪ Switching off: Release ON/OFF switch (11).
Continuous use:
▪ Switching on: Press ON/OFF switch (11) and in
pressed position lock it by button (12).
▪ Switching off: Press ON/OFF switch (11) once and
release it immediately.
WARNING: Before plugging in the tool, al-
ways check to see that the trigger switch (11) actuates
properly and returns to OFF position when released.
SMOOTH ELECTRONIC RPM CONTROL
Light pressure on ON/OFF switch (11) results in low rota-
tion speed, further pressing the switch results in smooth
increase of the rpm to maximum upon reaching the ex-
treme position.
SELECTION OF RPM VALUE
The necessary speed can be pre-selected by rotating
the regulator dial (10) clockwise or anti-clockwise.
REVERSING
The extreme position of lever (9) to the right is equivalent
to anti-clockwise rotation, the extreme position to the left
- to clockwise rotation. When the ON/OFF switch (11) is
depressed lever (9) can not be actuated. Reversing can
be performed only when the spindle is not rotating!
OPERATION MODE SELECTION
Drilling holes in metal, wood, etc.
The switch (5) is in its extreme right position the
symbol "drill bit" being exposed.
Drilling holes in concrete, stone, etc.
The switch (5) is in its extreme left position the sym-
bol "hammer" being exposed.
SCREWING / UNSCREWING BOLTS, SCREWS
AND NUTS
Following the above-described procedure, tighten the cor-
responding accessory in chuck (2). Set the operation mode
selector switch (5) in the rightmost position until the drill bit
symbol could be seen entirely. Select the rotation direction
necessary by lever (9). These operations must be per-
formed only at low rpm.
WARNING: In case of screwing / unscrewing
long bolts and screws there is a danger of slipping the drill.
