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 environmental 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 the tool is used to remove the bolt, its torque shall not be greater than the rated torque value. Generally, bolts that are not tightened or seriously rusted by this wrench should not be removed by 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 must be carried out after the motor stops rotating. It is strictly forbidden to move 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秒后再進行開動扳手，否則扳手不能啟動。
6. When the wrench stops automatically, the switch can be released (if the switch is opened continuously, the wrench will start automatically after 5 seconds) and the wrench can be started after 4-5 seconds, otherwise the wrench cannot be started.
