Design features
of the power tool
Operation mode regulator (see fig. 16-17)
Switching the operation modes shall be
carried out only in the off mode of the
tool's motor.
Function switches 10 and 17 are fitted
with lock button 9 that is used to fix
the function switch in a set position.
Rotate function switches 10 or 17 while
pressing button 9 in order to set a desired
operating mode.
[BH10-28 VB, BH15-32 VB]
Function switch 10 is designed for the switching the
following operation modes of the tool (see fig. 16):
Drilling (set the function switch 10 in the position indi-
cated in figure 16.1) - non-percussion drilling in wood,
synthetics, metal�
Percussion drilling (set the function switch 10 in the
position indicated in figure 16.2) - percussion drilling in
masonry, concrete, natural stone�
Chisel rotation (set switch 10 in the position shown on
figure 16.3) - 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 10 in the position
indicated in figure 16.4) - chiselling ducts in masonry,
concrete, stone, removing ceramic tiles�
[BH13-30 VB, BH15-36 VB]
Function switches 17 and 18 are designed for the
switching the following operation modes of the
tool (see fig. 17):
Drilling (set the function switches 17 and 18 in the
positions indicated in figure 17.1) - non-impact drilling
in wood, synthetics, metal�
Impact drilling (set the function switches 17 and 18 in
the positions indicated in figure 17.2) - impact drilling
in masonry, concrete, natural stone�
Chiselling (set the function switches 17 and 18 in
the positions indicated in figure 17�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.
Speed selector thumbwheel
[BH10-28 VB,
BH15-36 VB]
Use speed selector thumbwheel 12 to set required
revolutions and impact frequency�
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�
Vibration protection system
[BH10-28 VB,
BH15-36 VB, H13-05 B, H17-11 B]
The vibration protection system is design to reduce
vibration impact (during operation) on the operator�
Safety clutch
[BH10-28 VB,
BH15-36 VB]
The safety clutch protects the power tool against
overload 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 4 when
working, it will ensure a better control of
your electric tool and reduce recoil.
Drilling (see fig. 18-19)
[BH10-28 VB,
BH15-36 VB]
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. 18.1).
• 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 18.2.
• 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 center and drill after that (see
fig. 19). Caution: drill tiles in the impactless drilling
operation mode only.
