1、接通電源前應(yīng)先查看電源電壓是否與本產(chǎn)品銘牌相符，是否有接地裝置。當(dāng)電源電壓超出10%時應(yīng)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 the power supply, check whether the power supply voltage is consistent with the nameplate of the product and whether there is a grounding device. When the power supply voltage exceeds 10%, voltage stabilizing measures shall be taken, otherwise the control accuracy will be affected. Poor grounding is easy to cause accidents.
2、工具使用的環(huán)境溫度為-10℃-40℃，過高過低都會影響控制精度。
2. The ambient temperature of the tool is - 10 ℃ - 40 ℃, too high or too low will affect the 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擰。
3. The initial torque of the screwed bolt shall not be greater than 70% of the rated torque of the tool. The bolts shall not be re tightened 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?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 the tool is used to remove the bolt, its torque shall not be greater than the rated torque. Generally, the bolts that are not tightened or seriously rusted by this wrench should not be removed 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(jìn)行，嚴(yán)禁在運轉(zhuǎn)中撥動正反開關(guān)。
5. When changing the rotation direction, it must be carried out after the motor stops rotating. It is strictly prohibited to toggle the positive and negative switches during operation.
6、當(dāng)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(jìn)行開動扳手，否則扳手不能啟動。
6. When the wrench stops automatically, loosen the switch (if the switch is not opened, the wrench will start automatically after 5 seconds). Start the wrench after 4-5 seconds, otherwise the wrench cannot start.
