• Install the adapter 17 (SDS PLUS) into the
chuck 1 (SDS PLUS), repeating the same steps as
when mounting the borer (chisel) see fig. 6.
• When dismantling, repeat the steps described
above in the reverse order�
Attention: keep in mind that in the
process of mounting / dismounting of
the gear rim chuck 16 the screw 18 has a
left-hand thread.
Mounting / replacement of accessories (see fig. 7)
• Release the cams grip with drill chuck key 19, then ro-
tate the quill of gear rim chuck 16 counter-clockwise with
your hand (see fig. 7) until the cams move apart at the
distance allowing an accessory to be mounted / replaced�
• Mount / replace an accessory�
• Rotate the quill of gear rim chuck 16 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 16 with drill
chuck key 19 applying a similar torque to each of the
three openings on the side surface of the chuck�
With long-term use the drill bit may
become very warm; use gloves to
remove it.
Initial operating of the power tools
• 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 approximately 15 s
(at ambient temperature of 32°С) up to 2 minutes (at
ambient temperature of 0°С).
Switching the power tool on / off
Switching on:
Press on / off switch 12�
Switching off:
Release the on / off switch 12�
Design features of the power tool
Operation mode regulator (see fig. 8)
Switching the operation modes shall be
carried out only in the off mode of the
tool's motor.
Function switch 7 are fitted with lock
button 8 that is used to fix the function
switch in a set position. Rotate function
switch 7 while pressing button 8 in
order to set a desired operating mode.
Function switches 7 and 11 are designed for the
switching the following operation modes of the
tool (see fig. 8):
Drilling (set the function switches 7 and 11 in the
positions indicated in figure 8.1) - non-percussion
drilling in wood, synthetics, metal�
Percussion drilling (set the function switches 7
and 11 in the positions indicated in figure 8.2) -
percussion drilling in masonry, concrete, natural stone�
Chiselling (set the function switches 7 and 11 in the
positions indicated in figure 8.3) - chiselling ducts in
masonry, concrete, stone, removing ceramic tiles�
In order to make switching between
the operation modes smoother, rotate
slightly chuck 1 (SDS PLUS) by hand.
Vibration protection system
The vibration protection system is design to reduce
vibration impact (during operation) on the operator�
Safety clutch
The safety clutch protects the power tool against over-
load and damage in case of accessory sticking during
drilling�
Recommendations on the power tool
operation
Wear thick soft gloves when working to
reduce vibration impact on your body.
• Always use additional handle 4 when working, it will
ensure 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
due to the impact mechanism design� This is why do
not exert excessive pressure on your electric tool, as it
may result in borer seizing and motor overload�
• In order to decrease dust production when drilling
holes in walls and ceilings, take actions indicated in
fig. 9. Mount dust collector 14 as shown in figure 9 for
drilling holes in the ceilings�
Caution: drill wood and metals in the
impactless drilling operation mode only.
• Grease the drill bit regularly when drilling holes in
metals (except drilling non-ferrous metals and their
alloys)�
• When drilling hard metals, apply more force to the
power tool and lower the rotation speed�
• When drilling large diameter holes in metal, first
drill a hole with a smaller diameter and ream it till the
necessary diameter (see. fig. 11).
• In order to avoid splitting of the surface at an exit
point of a drill bit when drilling holes in wood, follow the
instructions shown in figure 12.
• When drilling holes in glazed ceramic tiles, in order to
improve the drill centering accuracy and to save the glaze
from damage, apply adhesive tape to the presumed hole
