complete discharge, the power tool is automatically
switched off� Attention: do not try to switch on the
power tool when the protection system is acti-
vated the battery of the power tool can be dam-
aged.
Temperature protection
The temperature protection system enables to auto-
matically deactivate the power tool in case of excess
load or when the temperature of the battery is exceed-
ing 80°C� The system guarantees protection of the
power tool from damage in case of noncompliance
with the operation conditions�
Overload protection
Overload protection system of the engine automati-
cally switches off the power tool when it is operated
in a manner that causes it to draw an abnormally high
current�
Battery charge state (see fig. 6)
Within a few seconds after turning the power tool on
and off indicators 1 show the state of charge of the
battery (see fig. 6). Note: reverse switch 2 should be
set in the position "F" or "R".
LED lamp
When power tool is switched on, the LED lamps 5 is
automatically light up that allows to carry out works in
low light conditions�
Changing the rotational directions (see fig. 7-8)
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 left (unscrewing) - move the reverse
switch 2 backward ("▼", "R" see fig. 7.1)�
Rotation to the right (screwing in) - move the reverse
switch 2 forward ("▲", "F" see fig. 7.2)�
Spindle locking - move the reverse switch 2 to the
middle position (see fig. 8)� This enables to use the
power tool as an ordinary screwdriver (for example
it can be used to tighten manually screws, if the
battery is low)� Attention! tightening torque must
not exceed 10 Nm, otherwise you may damage
the power tool, such damage will void your
warranty.
Torque adjustment (see fig. 9)
Press and release the button 3 in order to set one
of three torque values most suitable for the work
performed�
The set torque value is shown by indicators 1 (see
fig. 9):
• low torque (short indicator 1 is light up) - for
screwing in screws with small diameter or into soft
material;
• middle torque (middle indicator 1 is light up) - for
screwing in screws with middle diameter or into soft
material;
• high torque (long indicator 1 is light up) - for
screwing in screws with large diameter or into hard
material�
Recommendations on the power tool

Power tool maintenance / preventive
measures
Battery maintenance instruction
• Charge timely before the battery is completely ex-
hausted� Stop operation in low power and charge it
immediately�
• Do not overcharge when the battery is full, otherwise
it will shorten the life time�
• Charge battery in the room temperature of 10°C
to 40°C (50°F to 104°F)�
• Charge battery 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 and
the need for replacement� It should be taken into ac-
count that the battery 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 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�
