1、接通電源前應(yīng)先查看電源電壓是否與本國(guó)產(chǎn)品銘牌相符，是否有接地裝置。當(dāng)電源電壓超出+10%時(shí)應(yīng)采取穩(wěn)壓措施，否則影響控制精度。接地不良易造成事故。

1. Before connecting the power supply, check whether the power supply voltage matches the nameplate of the domestic product and whether there is a grounding device. When the power supply voltage exceeds+10%, voltage stabilization measures should be taken, otherwise it will affect the control accuracy. Poor grounding can easily cause accidents.

2、工具使用的環(huán)境溫度為-10℃-40℃，過(guò)高過(guò)低都影響控制精度。

2. The ambient temperature for tool use is -10 ℃ -40 ℃, and both high and low temperatures can affect control accuracy.

3、被擰螺栓的初始扭矩不得大于工具的額定扭矩的70%。螺栓達(dá)到額定扭矩后不得重?cái)Q。

3. The initial torque of the tightened bolt shall not exceed 70% of the rated torque of the tool. Do not tighten the bolt again after reaching the rated torque.

4、工具用于拆卸螺栓時(shí)，其扭矩不得大于額定扭矩值。一般情況下，不是本扳手?jǐn)Q緊的或銹蝕嚴(yán)重的螺栓，不宜用本扳手拆卸，以免造成工具損壞。

4. When tools are used to disassemble bolts, their torque must not exceed the rated torque value. In general, bolts that are not tightened with this wrench or severely corroded should not be disassembled with this wrench to avoid tool damage.

5、變換旋轉(zhuǎn)方向時(shí)，建議待電機(jī)停止轉(zhuǎn)動(dòng)后進(jìn)行，嚴(yán)禁在運(yùn)轉(zhuǎn)中撥動(dòng)正反開(kāi)關(guān)。

5. When changing the direction of rotation, it is necessary to wait until the motor stops rotating, and it is strictly prohibited to toggle the forward and reverse switches during operation.

6、當(dāng)扳手自動(dòng)停止后即可松開(kāi)開(kāi)關(guān)（如果不斷開(kāi)開(kāi)關(guān)，過(guò)5秒鐘扳手就自行啟動(dòng)）待4-5秒后再進(jìn)行開(kāi)動(dòng)扳手，否則扳手不能啟動(dòng)。

6. After the wrench stops automatically, you can release the switch (if you keep opening the switch, the wrench will start automatically after 5 seconds). Wait for 4-5 seconds before starting the wrench, otherwise the wrench cannot start.
