1、接通電源前應先查看電源電壓是否與本國產(chǎn)品銘牌相符，是否有接地裝置。當電源電壓超出+10%時應采取穩(wěn)壓措施，否則會影響控制精度。接地不良易造成事故。
1. Before connecting to the power supply, it is necessary to 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℃，過高過低會影響控制精度。
2. The ambient temperature for tool use is -10 ℃ -40 ℃, which can affect control accuracy if it is too high or too low.
3、被擰螺栓的初始扭矩不得大于工具的額定扭矩的70%。螺栓達到額定扭矩后不得重擰。
3. The initial torque of the tightened bolt shall not exceed 70% of the rated torque of the tool. Do not retighten the bolt after reaching the rated torque.
4、工具用于拆卸螺栓時，其扭矩不得大于額定扭矩值。一般情況下，不是本扳手擰緊的或銹蝕嚴重的螺栓，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 should not exceed the rated torque value. In general, bolts that are not tightened or severely rusted with this wrench should not be disassembled with this wrench to avoid tool damage.
5、變換旋轉(zhuǎn)方向時，必須待電機停止轉(zhuǎn)動后進行，嚴禁在運轉(zhuǎn)中撥動正反開關(guān)。
5. When changing the direction of rotation, it is necessary to wait for the motor to stop rotating, and it is strictly prohibited to move the forward and backward switches during operation.
6、當扳手自動停止后即可松開開關(guān)（如果不斷開開關(guān)，過5秒鐘扳手就會自行啟動）待4-5秒后再進行開動扳手，否則扳手不能啟動。
6. After the wrench automatically stops, you can release the switch (if you keep opening the switch, the wrench will start itself after 5 seconds). Wait for 4-5 seconds before starting the wrench, otherwise the wrench cannot start.
