9. 操作：
插入电池组时请务必使其完全锁紧到位，否则它可能会意外从工具中脱落从而造成自身或他人受伤。牢牢握住工具
并将套筒置于螺栓或螺母上方，开启机器并以适当的紧固时间开始紧固。
适当的紧固转矩可能会随着螺栓种类或尺寸、需紧固工件材料等的不同而不同。总体上，紧固时间越久紧固转矩越大。
注：
使工具平直对准螺栓或螺母。
紧固转矩过大可能损坏螺栓螺母或套筒，开始工作前，请务必进行试运转以确定适用于螺栓或螺母的适当紧固时间。
如果工具连续工作到电池组电量耗尽，则应暂停使用工具 15 分钟，再用已充电的电池组继续操作。
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）套筒：
a）使用尺寸不正确的套筒，将会造成紧固转矩减小。
b）已经破损的套筒（六角端或矩形端磨损）会减小紧固转矩。
3）螺栓：
a）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。
b）即使螺栓的直径相同，但依其转矩系数等级及其长度不同，所需紧固转矩也不相同。
4）使用万向节或延伸杆会在某种程度上减少冲击套筒扳手的紧固力，可通过延长紧固时间进行弥补。
5）握持工具的方式或上螺栓部位的材料也会影响转矩。
6）低速操作本机也会减小紧固转矩。
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。

中文 EN DE RU KO PT JA ES

2）为什么在螺钉还未拧紧时，手电钻就停止运转？
此时请调节在机身和夹头之间的扭力调节圈。位置 1对应的扭力最小，位置 20 对应的扭力最大。位置 21 是专为
钻孔所用。把扭力调节圈调节到更高档位就可以解决此问题了。
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 45℃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。
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，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 guideline:
Caution:
Please read the instruction carefully before operating the machine.
Before the 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.
2.Speed regulation with switch:
Force applied to the switch can change the 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. Change of rotation direction（see Figure D）:
Forward: Push the side of reversing yoke（2）marked with " " to the end（left side）for drilling and driving the screw.
Reverse: Push the side of reversing yoke marked with " " to the end（right side）for releasing or unscrewing the screw the screw.
Warning:
The rotating speed can only be changed after the machine is completely still.
6. Installation and removal of socket（see Figure E）:
Caution:
When installing or removing the sleeve, be sure to confirm that the drill has been turned off and that the battery pack has
been removed.
1）Socket without O-ring and pin:
a）Install the socket: Press it onto the square drive bit（1）of the tool until it is fully in position.
b）Remove the socket: For removal, it is only necessary to pull it out.
c）Tap it gently if necessary.

Warning:
Before starting the machine tool, ensure that the socket has been installed properly.
7.Work light:
Machine is equipped with the work light: when the switch is pressed, the light will come on; when it is released, the light will go out 15s
later.
8.Battery level indication:
When the machine switch is pressed, the battery indicator will stay on for 5s. The remaining capacity of battery pack may be determined
according to the following table.
LED display Remaining battery
0-25%
25-50%
50-75%
75-100%
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:
a）Using the wrong size socket will result in a reduction in tightening torque.
b）Damaged sockets（worn at the hexagonal or rectangular ends）will reduce the tightening torque.
3）Bolt:
a）Even if the torque coefficient and bolt grade are the same, the required tightening torque will be different due to the diameters.
b）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.
