before use.
Usage
This tool is used to screw or drill holes in wood, metal,
plastic and to drill holes in lightweight concrete or
brick walls.

Installation of battery pack
INSTALLATION
CHUCK ADJUSTMENT
Warning: When replacing
accessories, make sure that
the power supply is cut off and the
switch is turned off (the reversing
lever is in the middle position). When
starting the tool, make sure that there
is no hidden danger to the drill bit.
Damage or loosening of the chuck
may cause personal injury.

OPERATION
Forward and reverse switching
Warning: The direction
of rotation can not be
changed until the machine is
completely stationary.
SPEED SHIFT
TORSION ADJUSTMENT
Torque selection
The tripping torsion corresponding
to position 1 is the smallest, and that
corresponding to position 20 is the
largest.
Mode switch
Drilling mode
Screw batch mode
Hammer drill mode (drilling on
lightweight concrete and brick walls)
Start/stop
Warning: Do not use
start-stop switch for long
time and low speed operation,
otherwise the machine may
overheat and cause tool
damage.
LED indication
The LED will be lit when the switch is
pressed. When the switch is released,
the LED will automatically go out.
The tool and battery are equipped
with automatic power-off protection
system. The LED flickers for
3 seconds and then goes off,
indicating that the protection system
works. At this time, the system
automatically cuts off the power
supply to prolong the battery life.
Pictures
The following situations may trigger
automatic power-off protection:
• Overload: Tools are
See Figure A1
overloaded when they are
running, the current is too high.
See Figure A2
In this case, release the switch,
stop the operation leading to tool
See Figure A3
overload, and restart the switch.
• Overheat: In the case above, if
the tool is not started, the tool and
battery may be overheated. In this
case, cool the tool and battery pack
before starting the switch again.
• Low voltage: The tool does
not work when the remaining
capacity is too low. In this case,
dismantle and replace the battery pack.

FAQS
1. WHY HAS THE SWITCH BEEN PRESSED AND
THE MACHINE DOES NOT WORK?
See Figure
There is a reversing lever at the top of the switch. When

it is in the middle position, the machine will lock the
start-stop switch. Put it where it needs to be turned and
press the button, the machine will start to rotate.
See Figure D
2. WHY DOES THE ELECTRIC DRILL STOP
RUNNING BEFORE THE SCREW IS TIGHTENED?
Confirm whether the mode switching ring is on position
See Figure E
, and adjust the torque regulating ring to a higher
position. The tripping torsion corresponding to position
1 is the smallest, and that corresponding to position
20 is the largest. Adjust the mode change-over ring to
position
also adjust the mechanical shift lever to the low speed
See Figure F
(position 1) for greater mechanical transmission torque.
3. WHY IS THE WORKING TIME OF THE SAME
BATTERY PACK SOMETIMES LONG AND
SOMETIMES SHORT?
As mentioned above, if a battery pack is left unused
for too long, its working time will be shortened. Such

situation will be improved after charging and using
for several times. Under doing heavy work, such as
screwing big screw into hard wood, the battery power
will be consumed very fast. Do not charge in the
environment below 0 or above 40℃, which will also
affect the performance of the battery pack.
Warning: Make sure the
reversing lever is on the left or
for maximum torque (no trip), and you can
