Caution: drill wood and metals in the im-
pactless drilling operation mode only.
• Grease the drill bit regularly when drilling holes in met-
als (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 nec-
essary diameter (see fig. 15.1).
• 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 15.2.
• 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. 16).
Caution: drill tiles in the impactless drilling opera-

Battery maintenance instruction
• Charge timely before the battery 14 is completely
exhausted� Stop operation in low power and charge it
immediately�

to 40°C (50°F to 104°F)�
• Charge battery 14 every 6 months without operation
for a long time�
• Replace worn out batteries in time� Decline of pro-
duction or a significantly shorter runtime of the power
tool after charging indicates aging of the battery 14 and
the need for replacement� It should be taken into ac-
count that the battery 14 may discharge faster if the
works take place in the temperature below 0°С.
• In case of long time storage without use, it is recom-
mended to store the battery 14 at room temperature, it
should be charged to 50%�
