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.

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
right to the stop�
Impact drilling:
To switch to this operation mode, move
switch
6
left 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
11
� Weak
pressing results in low revolutions, which
enable a smooth power tool switch-on�
Speed selector thumbwheel
Use speed control 9 to set required revolutions and
impact frequency�

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�

Attention: one can only change the revo-
lutions per minute range after the engine
fully stops.
The first speed - you can find the values of
the revolutions per minute range in the tech-
nical specifications table.
The second speed - you can find the val
-
ues of the revolutions per minute range in
the technical specifications table.
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
8
to the right�
Rotation to the left (unscrewing)
- move the rota-
tional direction switch
8
to the left�
Level indicator (see fig. 10)
[SBM-500, SBM-600]
The level indicator
12
shows the position of the power
tool case in the horizontal plane (see fig. 10). The pow
-
er tool case is in the horizontal position if the air bubble
is in the middle of the level indicator

Recommendations
on the power tool operation
Drilling (see fig. 11-15)
•
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. 11).
•
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 12.
•
In order to decrease dust production when drilling holes
in walls and ceilings, take actions indicated in fig. 13-14.
•
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. 15). Start
drilling at lower speed increasing it as the hole deep-
