the power tool from damage in case of noncompliance
with the operation conditions�
Indicators of the state of battery charge (see fig. 6)
With the push of the on / off switch 7 the indicators 6
shows the state of charge of the battery (see fig. 6).
• 3 indicators 6 (green, yellow, red) light up -
charge 100%;
• 2 indicators 6 (yellow, red) light up - charge 50%;
• 1 indicators 6 (red) light up - battery discharged�
LED lamp
When the on / off switch 7 is pushed, the LED lamp 5
is automatically switched on that allows to carry out
works in low light conditions�
Torque regulator
Rotate the regulator 2 in order to set one of the 20
torque values most suitable for the work performed�
It is recommended to set the torque
regulator 2 into the position "Drill" to perform
drilling�
Stepless speed adjustment
Speed is controlled from 0 to maximum by
pressing force of on / off switch 7 � Weak
pressing results in low revolutions, which
enable a smooth power tool switch-on�
Step speed selector switch
Attention: one can only change the revo-
lutions per minute range after the engine
fully stops.
In order to choose the "1" gear, move the switch 3
back� This mode is used for the fastening of screws or
for large diameter hole drilling�
In order to choose the "2" gear, move the switch
3
forward� This mode is used for speed drilling of small
diameter holes�
Changing the rotational directions (see fig. 7)
Change the direction of rotation only
after a full stop of the motor, acting oth-
erwise may cause damage to the power
tool.
Clockwise rotation (drilling, fastening of screws) -
move the reverse switch 8 to the left as it is shown in
fig. 7.1.
Counter clockwise rotation (unscrewing the
screws) - move the reverse switch 8 to the right as it is
shown in fig. 7.2.
Break rundown
Break rundown stops the keyless chuck 1 immediately
after the power tool is turned off� This helps to avoid
an excessive tightening of the bolts and screws and
prevents work pieces, screwdriver bits and slots of fas-
tening elements from being damaged�
Recommendations
on the power tool operation
Drilling (see fig. 8-10)
• 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 nec-
essary diameter (see fig. 8.1).
• 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 8.2.
• In order to decrease dust production when drilling
holes in walls and ceilings, take actions indicated in
figure 9-10.
Screwing the screws (see fig. 11)
• 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 11.
Power tool maintenance /
preventive measures
Before execution of any procedures, centre the re-
verse switch 8.
Battery maintenance instruction
• Charge timely before the battery 10 is completely
exhausted� Stop operation in low power and charge it
immediately�
• Do not overcharge when the battery 10 is full, other-
wise it will shorten the life time�
• Charge battery 10 in the room temperature of 10°C
to 40°C (50°F to 104°F)�
• Charge battery 10 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 10 and
the need for replacement� It should be taken into ac-
count that the battery 10 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 10 at room temperature, it
should be charged to 50%�
Cleaning of the power tool
An indispensable condition for a safe long-term exploi-
tation of the power tool is to keep it clean� Regularly
flush the power tool with compressed air thought the
ventilation slots 4 �
