gear rim chuck 14 the screw 15 has a left-
hand thread.
Mounting / replacement of accessories
With long-term use the drill bit may be-
come very warm; use gloves to remove
it.
Gear rim chuck (see fig. 8)
• Release the cams grip with drill chuck key 13, then
rotate the quill of gear rim chuck 14 counter-clockwise
with your hand (see fig. 8.1) until the cams move apart
at the distance allowing an accessory to be mounted /
replaced�
• Mount / replace an accessory (see fig. 8.2).
• Rotate the quill of gear rim chuck 14 clockwise with
your hand in order to lock the accessory mounted� Do
not allow the accessory to become distorted�
• Tighten the cams of gear rim chuck 14 with drill chuck
key 13 applying a similar torque to each of the three
openings on the side surface of the chuck (see fig. 8.3).
Initial operation of the
power tool
•
Always use the correct supply voltage the power
supply voltage: must match the information quoted on
the power tool identification plate.
• The power tool is supplied properly lubricated and
ready for use�
• A new power tool needs some time for its parts to
run in before a full load operation� The run-in period
duration is about 5 hours of operation�
• The gear lubrications require a short time to get
warm� Depending on the ambient temperature this
period of time can alter within the range of approxi-
mately 15 s (at ambient temperature of 32°С) up to 2
minutes (at ambient temperature of 0°С).
Switching the power
tool on / off
Short-term switching on / off
To switch on, press and hold on / off switch 11, to
switch off - release it�
Long-term switching on / off
Switching on:
Push on / off switch 11 and lock it in the position with
lock-on button 12�
Switching off:

Design features
of the power tool
Function switch (see fig. 9)
Switching the operation modes shall be
carried out only in the off mode of the
tool's motor.
Function switch 8 is fitted with lock
button 7 that is used to fix the function
switch 8 in a set position. Rotate function
switch 8 while pressing button 7 in order
to set a desired operating mode.
Function switch 8 is designed for the switching the
following operation modes of the tool:
Drilling (set the function switch 8 in the position indi-
cated in figure 9.1) - non-percussion drilling in wood,
synthetics, metal�
Percussion drilling (set the function switch 8 in the
position indicated in figure 9.2) - percussion drilling in
masonry, concrete, natural stone�
Chisel rotation (set switch 8 in the position shown on
figure 9.3) - this mode does not allow operating your
power tool, but allows setting the chisel in a comfort-
able position for chiseling works�
Chiselling (set the function switch 8 in the position
indicated in figure 9.4) - chiselling ducts in masonry,
concrete, stone, removing ceramic tiles�
In order to make switching between the
operation modes smoother, rotate slight-
ly chuck 1 (SDS PLUS) by hand.
Stepless speed adjustment
Speed is controlled from 0 to maximum by
pressing force of on / off switch 11� Weak
pressing results in low revolutions, which
enable a smooth power tool switch-on�
Changing the rotational directions (see fig. 10)
Change the direction of rotation only
after a full stop of the motor, acting oth-
erwise may cause damage to the power
tool.
Clockwise rotation (drilling, fastening of screws) -
move the rotational direction switch 10 as it is shown
in fig. 10.1.
Counter

screws) - move the rotational direction switch 10 as it
is shown in fig. 10.2.
Safety clutch
The safety clutch protects the power tool against over-
load and damage in case of accessory sticking during
drilling�
on the power tool operation
Wear thick soft gloves when working to
reduce vibration impact on your body.
• Always use additional handle 6 when working, it will en-
sure a better control of your electric tool and reduce recoil�
• At impact drilling the result does not depend on the
pressing force you apply to your electric tool, which is
