is not needed
for extended screwdriver bits

for screwdrivers)�
Initial operating
of the power tool
Always use the correct supply voltage: the power sup-
ply voltage must match the information quoted on the
power tool identification plate.
Switching the power
tool on / off
Short-term switching on / off
To switch on, press and hold on / off switch
12
, to
switch off - release it�
Long-term switching on / off
Switching on:
Push on / off switch
12
and lock it in the position with
lock-on button

Switching off:
Push and release on / off switch

Design features
of the power tool
"Impact / drill" switch
Switch 6 is purposed for switching between the follow-
ing operation modes of the power tool:
• drilling, screwing, unscrewing
- drilling without
impact in wood, synthetic materials, metal� Screwing
and unscrewing fastening components;
• impact drilling
- impact drilling in brick, concrete,
natural stone�
Drilling, screwing, unscrewing:
To switch to this operation mode, move
switch 6 left to the stop�
Impact drilling:
To switch to this operation mode, move
switch 6 right to the stop�
One can switch to another operation mode without
stopping the power tool, simply decrease pressure
applied to it to some extent.
Stepless speed adjustment
Speed is controlled from 0 to maximum by
pressing force of on / off switch
12
� Weak
pressing results in low revolutions, which
enable a smooth power tool switch-on�
Speed selector thumbwheel
Use speed selector thumbwheel
11
to set required
revolutions and impact frequency�

Push on / off switch

•
Set the needed speed�
The required speed is dependent on the material and
can be determined with practical trials�
When operating your power tool at a low speed for a
long time, it has to be cooled down for 3 minutes� To
do it, set a maximum speed and leave your power tool
to run idle�
Changing the rotational directions
Change the direction of rotation only
after a full stop of the motor, acting oth-
erwise may cause damage to the power
tool.
Rotation to the right (drilling, screwing in)
- move
the rotational direction switch 9 to the right�
Rotation to the left (unscrewing)
- move the rota-
tional direction switch 9 to the left�
Recommendations
on the power tool operation
Drilling (see fig. 10-13)
•
Grease the drill bit regularly when drilling holes in
metals (except drilling non-ferrous metals and their al-
loys)�
•
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 neces-
sary diameter (see fig. 10).
•
In order to avoid splitting of the surface at an exit point
of a drill bit when drilling holes in wood, follow the in-
structions shown in figure 11.
•
In order to decrease dust production when drilling
holes in walls and ceilings, take actions indicated in
fig. 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 pre-
sumed hole center and drill after that (see fig. 13). Start
drilling at lower speed increasing it as the hole deep-
ens�
Caution: drill tiles in the impactless drilling
operation mode only.
Impact drilling
During the impact drilling, the result does not depend
on the pressure applied to the power tool - this is
caused due to the peculiarities in the impact mecha-
nism design� That is why you should not apply exces-
sive pressure to the power tool - it can jam the drill and
overload the engine�
Screwing the screws (see fig. 14)
•
To make fastening of screws easier and in order
to prevent cracking of the work pieces, first drill a
hole with a diameter equal to 2/3 of a diameter of the
screw�
•
If you are connecting work pieces with the help of
screws, in order to achieve durable joint without get-
ting cracks, fracturing or layering, take actions shown
in figure 14.
