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
51074
11
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，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:
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 button on the front of battery pack and pull it out. To insert the battery pack, simply push it into the machine while
avoiding 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.
3.Speed position selection（see Figure C）:
First select the position, and then regulate the rotating speed with switch; the highest position is selected at delivery and there are three
position indicators（6）where three ones going on means the high position, two ones going on means the mid position and one going on
means the low position: Change the position once each time you press the mark.
4.Switch lock（see Figure D）:
The switch has the lock protection function which helps to avoid the accidental activation of the hand drill. Lock the machine by adjusting
the reversing yoke（2）to the center position.
5.Rotation reversing（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 or removal of sleeve（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）Sleeve without O-ring and pin:
a）Install the sleeve: press it on the square driving head（1）of tool until it is fully seated.
b）Remove the sleeve: just unplug it.Gently tap it if necessary.
2）Sleeve with O-ring and pin:
a）Install the sleeve: Move the O-ring out of the sleeve groove, remove the pin on the sleeve, place the sleeve on the square driving
head（1）, align the hole in the sleeve with that on the square driving head, and fit the pin through the holes in the sleeve and
square driving head（1）, and then return the O-ring to the original position in the sleeve to fix the pin.
b）Remove the sleeve: please follow the reverse steps of installation.
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.

0-25%
25-50%
50-75%
75-100%
9.Operation:
Be sure to fully lock the battery pack as it may accidentally fall out of the tool and cause injury to yourself or others. Hold the tool firmly
and place the sleeve above the bolt or nut, turn the machine on and tighten it properly.
The tightening torque may vary depending on the type or size of bolt and the material of workpiece to be fastened. Generally, the longer
the tightening time is, the larger the tightening torque is.
Note:
Align the tool straightly with the bolt or nut.
Excessive tightening torque may damage the bolt nut or sleeve. Before the operation, be sure to conduct the test run to determine the
proper tightening time for the bolt or nut.
If the tool keeps operating until the battery pack is exhausted, the operation shall stop for 15min, and then continue the operation with
the charged battery pack.
Tightening torque depends on the various factors 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）Sleeve:
a）Incorrectly sized sleeve will result in the decrease of tightening torque.
b）Damaged sleeve（wear of hex end or rectangular end）will reduce the tightening torque.
3）Bolt:
a）Even if the torque coefficient and the bolt level are the same, the tightening torque is different because of the different
diameters.
b）Even if the diameter of bolt is the same, the required tightening torque is different depending on its toque coefficient and its
length.
4）Universal joint or extension rod will reduce the tightening force of the impact sleeve wrench to some extent, which can be
compensated by the extension of tightening time.
5）The way the tool is held or the material on the bolt will also affect the torque.
