问题解答：
1、为什么按压开关而机器却不运转？
在开关上部有一个转向拨杆，处在锁住的位置。将
其拨向需要转动方向的位置，再按下按钮，机器就
会开始转动。
2、为什么在还未拧紧时，机器就停止运转？
机器带有低压保护，在电池包电量过低时，机器不
能工作，请确认电池包电量。
本机带有温度保护，当长时间满负荷工作时，电池
包会过热，温保系统会启动导致机器停止运转，请
将机器冷却到常温后再继续使用。
3、为什么同一个电池包的工作时间会有长有短？
一个电池包如果放置时间过长而不使用的话，就会
缩短其工作时间，这就是充电次数问题。在经过几
次充电和使用之后，这种状况就会得到改善。在干
重活时，电池包的电量也会消耗的很快。不要在 0℃
以下或 35℃以上的环境里充电，这同样会影响到电
池包的工作表现。
保养与维护
对机器作任何换修工作之前，请务必先拔出插头。
您的电动工具不需要再添加润滑油或进行其它保养。
不要用水或化学清洗剂来清洗你的电动工具，用干
布擦拭干净就可以了。工具需储藏在干燥的环境中，
并保持马达通风口处的清洁。尽量不要在灰尘较大
的环境中使用。
为了有利于与电池包寿命，请注意：
1）电池包存放：将电池包充电 30%-50% 电量，存
放在 26℃以下环境中。
2）不超过 6个月时间，将电池包充满电使用一次。
废弃电池包的处理
为保护自然环境，请妥善回收或处理电
池包。该电池包含有锂电池。请向当地
废物处理部门咨询有关回收和（/或）
处理的信息。通过使用机器把电池包电
量耗尽，卸下电池包，用结实的胶带包
裹好极片端口，避免短路和漏电。请勿
试图打开或拆取任何部件。
环境保护
处理废弃物
为了响应环保，对于坏损的机器、配
件及包装材料必须详细加以分类处理，
以便利于回收。
为方便分类回收，各塑胶部位都做有
材料标识。

OPERATION INSTRUCTIONS
Before use
1) Charging
The charger shall be used with the machine tool.
Using other chargers is not allowed.
The machine tool is equipped with a protective
circuit. When the battery level is low, the
protective circuit will open and the machine tool
will stop rotating.
The machine tool may heat up in higher
temperature environments or after long use.
In this case, please do not immediately charge
it until it has cooled down, or else the service
life of the battery will be shortened or it will
not be possible to charge the battery due to
overheating.
When the machine tool is charged for the first
time or is not used for a long time, the efficiency
of the charger may only reach about 60%, and
should reach 100% again after 2–3 instances of
charging and discharging.
2) Installation/removal of battery pack (see
Figure A)
To remove the battery pack, press down the lock
button in front of the battery pack and pull it
out. To insert the battery pack, just push it into
the machine tool. Do not apply excessive force.
OPERATION
1. Start/stop (see Figure B)
Press and hold switch (1) to start the machine
tool, then release it to stop the machine tool.

speed. The change range is from 0 to maximum
speed. When the force applied is low and the
speed is low, the starting speed will be low,
making the tool stable and easy to control. After
a stable and reliable start, fully press down the
switch for a higher speed.
3. Speed position selection (see Figure C)
During use, select the gear and control the
speed with the switch. Upon delivery, the
machine tool is set at the highest gear. The gear
indicator (6) is provided by three red indicators.
If 3 red indicators are on, this indicates a high
gear; if 2 red indicators are on, this indicates
a medium gear; and if 1 red indicator is on,
this indicates a low gear. If the gear selection
must be changed, press the icon to change
through the gears one by one.
WARNING
Do not press the switch for a long time when
operating at low speed as this will cause the
internal part of the machine tool to become
overheated. Change the speed gear of the
machine tool after each stop.
4. Switch locking (see Figure D)
The switch has a locking protection function will
is beneficial for helping to reduce the possibility
of misstarting the machine tool after a period
of disuse. Adjust the reversing yoke (2) to the
central position when the machine is not used
so as to lock the machine tool.
5. Rotation reversing (see Figure D)
Forward rotation: Push the side of the reversing
yoke (2) marked “ " to the bottom (move to
the left side) and it can be used for tightening
bolts or nuts. Reverse rotation: Push the side
of the reversing yoke (2) marked " " to the
bottom (move to the right side) and it can be
used for loosening bolts or nuts.
WARNING
The rotation direction can only be changed after
the machine tool has completely stopped.
6. Installation and removal of socket (see
Figure E)
Attention: When installing or removing the
socket, ensure that the machine tool is powered
off and the battery pack is removed.
1) Socket without O-ring and pin
Install the socket: Press it onto the square drive
bit (1) of the tool until it is fully in position.
Remove the socket: For removal, it is only
necessary to pull it out. Tap it gently if necessary.
WARNING
Before starting the machine tool, ensure that
the socket has been installed properly.
7. Work light
The machine tool is equipped with a work light.
When the switch is pressed during operation, the
light will turn on; when the switch is released,
the light will turn off after a delay of 15 seconds.
8. Battery level indication
When you press the machine tool switch, the
battery level indicator will turn on for 5 seconds.
The remaining power level of the battery pack
can be judged according to the following table:
0-25%
25-50%
50-75%
75-100%
LED display Remaining battery

9. Operation
Be sure to fully lock the battery pack when
the battery pack is inserted, or else it may
accidentally fall from the tool and cause
personal injury. Hold the tool firmly, place the
socket on the top of the bolt or nut, start the
machine tool and start tightening at the proper
tightening time.
The proper tightening torque may vary along
with different types or sizes of bolts, and the
different workpieces to be tightened. Generally,
the longer the tightening time, the greater the
tightening torque.
Note:
• Align the tool with the bolt or nut.
• Excessive tightening torque may result
in damage to the bolt, nut or socket.
Before starting work, be sure to carry
out a commissioning trial operation to
determine the proper tightening time for
the bolt or nut.
• If the tool works continuously until the
battery pack runs out, it shall be paused
for 15 minutes before further operation
with a charged battery pack.
• Tightening torque is affected by the
following factors. After tightening, be sure
to confirm the torque with the torque
wrench.
1) When the battery is about to run out, the
voltage will drop and the tightening torque
will reduce.
2) Socket
• Using the wrong size socket will result in a
reduction in tightening torque.
• Damaged sockets (worn at the hexagonal
or rectangular ends) will reduce the
tightening torque.
2) Bolt
• Even if the torque coefficient and
bolt grade are the same, the required
tightening torque will be different due to
the diameters.
• Even if the diameter of the bolt is the
same, the required tightening torque will
be different due to the different torque
coefficient, as well as the grade and length
of the bolt.
4) The use of universal joints or extension
bars will reduce the tightening force of the
impact socket wrench to some extent, but
this can be compensated by extending the
tightening time.
5) The holding method of the tool or material
of the bolt will also affect the torque.
6) The low speed operation of the machine
tool will also reduce the tightening torque.
QUESTION AND ANSWER:
1. Why doesn’t the machine tool work after the
switch is pressed?
The reversing yoke on the top of the switch
is locked. Turn it to a position that requires
rotation, press the button and the machine tool
will start to rotate.
2. Why does the hand drill stop working before
the screw is tightened?
In this case, adjust the torque adjusting ring
between the body and the chuck. Position
1 corresponds to the minimum torque and
position 20 corresponds to the maximum
torque. Position 21 is designed for drilling. This
problem can be solved by adjusting the torque
adjusting ring to a higher gear position.
3. Why is the working time of the same battery
pack different?

19
V_SC_51075C_202104
As mentioned above, if a battery pack is used
for a too long a time, its working time will be
shortened. This is the problem of charging times.
After a few charges and uses, the situation will
improve. During such heavy work as turning
large screws into hardwood, the battery pack
will also run out quickly. Do not charge it in an
environment lower than 0 °C or higher than 45
°C as this will also affect the performance of the
battery pack.
MAINTENANCE
Be sure to remove the plug before making
any changes or repairs to the machine tool.
Your electric tools do not need to be filled
with lubricating oil or maintained. Do not
clean your electric tools in water or chemical
cleaning agent, just wipe them off with a piece
of dry cloth. The tools shall be stored in a dry
environment and their motor vents shall be kept
clean. Do not use in a dusty environment.
Disposal of discarded battery packs
1) Store the battery pack below 26 after
charging it to 30%-50%.
2) Charge the battery pack fully once in less
than 6 months.
DISPOSAL OF DISCARDED BATTERY
To protect the natural environment,
please recycle or dispose of battery
packs properly. The battery packs
contain lithium batteries. Please
consult the local waste disposal
department for information on
recycling and/or disposal. Run out
the battery pack with the hand drill,
remove the battery pack and wrap the
pole port with duct tape to avoid short
circuit and electric leakage. Do not
attempt to open or remove any part.
