8. 操作
适当的紧固转矩随螺丝／螺栓的种类或尺寸以及待
紧固工件的材料等因素而有所不同。
紧握工具并将起子头的尖端置于螺丝的头部。对工
具施加向前的压力达到使起子头不会从螺丝上滑落
的程度，这样便可启动工具开始操作。
1）冲击时间越久，扭矩越大，在 6-10S 左右达到
最大值。
2）速度越快，扭矩越大。
3）待紧固工件越硬，扭矩越大。
4）在拧小的螺钉时，低速短时拧紧螺钉，否则会
损坏螺钉。
• 使用适合螺丝／螺栓头部的起子头。
• 在拧螺丝时，最好预先钻个导向孔。
• 当紧固 M8 或更小号的螺丝时，选择合适的冲击力
并注意调节施加在开关扳机上的压力以免损坏螺
丝。
• 握持工具时将其笔直对准螺丝。
• 如果紧固螺丝的冲击力太强或紧固时间过久，螺
丝或起子头尖端将会受到过度的牵拉、挤、压损
坏等。在开始作业前，一定要进行测试操作以确
定所使用螺丝的适当紧固时间。
紧固转矩受下述多种因素影响。紧固后，请务必使
用转矩扳手确认转矩。
1）当电池组电量将要完全耗尽时，电压将会下降，
紧固转矩也会减小。
2）起子头或套筒起子头使用尺寸不当的起子头或
套筒起子头将会减小紧固转矩。
3）螺栓
• 即使转矩系数和螺栓等级相同，但因其直径不
同，所需紧固转矩也不同。
• 即使螺栓的直径相同，但因其转矩系数、等级
及其长度不同，所需紧固转矩也不相同。
4）握持工具的方式或上螺栓部位的材料也会影响
转矩。
5）低速操作工具也会减小紧固转矩。
�
使用短小的螺丝批头时，请利用磁性连接杆 ( 不含 )。
拧螺丝时，在螺纹上涂抹少许肥皂液或其他润滑液，
以便轻松拧入。
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。通过使用手电钻把电池包
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，

OPERATION GUIDELINE
Before the use
1) Charging
This charger and machine shall be used together. Do
not use other chargers.
The machine has a protection circuit. When the
battery is low, the protection circuit is turned on and
the machine stops rotating.
The machine may become hot under the high
temperatures or after a long period of operation. At
this time, do not charge immediately but wait until
the battery is cooled. Otherwise, the service life of
battery will be shortened or the charging failure may
be caused due to overheating.
For the first charging or after a long period of storage,
the efficiency of first charging may only reach about
60%. After 2-3 charging and discharging cycles, the
battery efficiency may reach 100%.
2) Installation and removal of battery pack (see
Figure A)
Press the lock buttons on both sides of battery pack
and pull it out. To insert the battery pack, simply push
it into the machine. Avoid the excessive force
OPERATION
1. Start/stop (see Figure B)
Press and hold the switch (1) to start the machine,
and release it to stop the machine.
2. Speed regulation
Change the force applied to the switch to regulate the
rotating speed. The range of adjustment is between
0 and the maximum rotating speed. The smaller the
force is, the lower the rotating speed is. The drilling
starts slowly and stably. After the stable and reliable
start, press the switch fully for higher speed.
WARNING
Do not operate at low speed for a long time by
pressing the switch. Otherwise the machine will be
overheating inside. Change the rotating speed after
stop.
3. Switch lock (see Figure C)
The switch has the lock protection function which

8. Operation
The proper tightening torque may vary depending
on the type or size of screw/bolt and the material of
workpiece to be fastened.
Hold the tool and place the tip of bit on the head of
screw. Apply a forward pressure to the tool to make
the screwdriver bit not slip off the screw, and start the
tool to begin the operation.
1) The longer the impact lasts, the greater the
torque is. The maximum value is achieved at
about 6-10 s.
2) The higher the speed is, the greater the torque
is.
3) The harder the workpiece to be fastened is, the
greater the torque is.
4) Be sure to tighten the small screw slowly for a
short time. Otherwise the screw will bedamaged.
Note:
1) Use a screwdriver bit that fits the screw /bolt
head.
2) When tightening the screw, it is best to pre-drill
a pilot hole.
3) When tightening the M8 or smaller screw, select
the appropriate impact force and take care to
adjust the pressure applied to the switch trigger
to avoid damage to the screw.
4) Hold the tool and align it with the screw.
5) If the impact force for fastening the screw is
too strong or the fastening time is too long, the
screw or screwdriver bit tip may be subjected
to excessive pulling, squeezing, pressure and
even be damaged. Be sure to perform a test
to determine the proper tightening time of the
screw before starting the job.
helps to avoid the accidental activation of the hand
drill. Lock the machine by adjusting the reversing yoke
(2) to the center position.
4. Rotation reversing (see Figure C)
Forward: Push the side of reversing yoke (3) marked
with “ " to the end (left side) for drilling a
hole and driving the screw. Reverse: Push the side of
reversing yoke marked with “ " to the end (right
side) for releasing or unscrewing the screw.
WARNING
The rotating speed can only be changed after the
machine is completely still.
5. Installation or removal of screwdriver bit
(see Figure D)
Caution: When installing or removing the bit, be sure
to confirm that the machine has been turned off and
that the battery pack has been removed.
The machine is designed with a quick-loading chuck
system;
When installing the screwdriver bit, pull the sleeve
forward and insert the screwdriver bit into the chuck.
Loosen the sleeve to fix the screwdriver bit.
When removing the screwdriver bit, pull the sleeve
forward and pull the bit out, and then release the
sleeve to reset it.
WARNING
Before starting the machine, make sure that the
screwdriver bit is fully fixed by the chuck.
6. Work light
Machine is equipped with the work light: when the
switch is pressed, the light will come on; when it is
released, light will go out.
7. Battery level display (Figure E)
When the machine switch is pressed, the battery
indicator will come on. The remaining capacity of
battery pack may be determined according to the
following table, and when the switch is released, the
indicator will go out.
Tightening torque is affected by many factors as
described below. After tightening, be sure to confirm
the torque with the torque wrench.
1) When the battery pack is about to run out
completely, the voltage will drop and the
tightening torque will also decrease.
2) The improperly sized screwdriver bit or sleeve
screwdriver bit may reduce the tightening
torque.
3) Bolt
Even if the torque coefficient and the bolt level are
the same, the tightening torque is different because
of the different diameters.
Even if the diameter of bolt is the same, the required
tightening torque is different depending on its toque
coefficient and its length.
4) The way the tool is held or the material on the
bolt will also affect the torque.
5) Operating at low speed will also reduce the
tightening torque.
WARNING
For the short screwdriver bit, use a magnetic
connecting rod (not included). When tightening the
screw, apply a little soap or other lubricant to the
thread to facilitate the operation.
QUESTION AND ANSWER:
1. Why does the machine not operate after the
switch is pressed?
A reversing yoke is located on the upper part of
switch. It is locked. Turn it to the position where the
rotation is in need, and then press the button to
rotate the machine.
2. Why does the hand drill stop when the screw has
not been tightened?
The machine has low-voltage protection. When the
level of battery pack is too low, the machine will not
work. Please confirm the level of battery pack.
The machine has temperature protection. When
the battery is working at full load for a long time,
the battery pack will overheat and the temperature
protection system will start to stop the machine.
Cool the machine to normal temperature before
resumption.
3. Why is the service life of same kind of battery pack
is different?
If a battery pack is left unused for a long time, its
service life may be shortened. This is the matter
of charging frequency. Repeated charging and
application may improve the situation. In case of
heavy work, the battery pack will run out soon. Do not
charge in a temperature below 0 °C or above 35 °C.
Otherwise, the performance of battery pack will be
affected.
