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.
本系列電動力矩扳手是裝配螺紋件及螺栓的機械化施工工具，具有自動控制扭矩功能。應用于栓焊結(jié)構(gòu)橋梁的架設，廠房、塔架及化工、冶、發(fā)電設備的安裝。大型機械、起重設備和車輛裝配作業(yè)，以及對螺紋緊固件的扭矩及軸向拉力有嚴格要求的場合。
This series of electric torque wrenches is a mechanized construction tool for assembling threaded parts and bolts, with automatic torque control function. Applied to the installation of bolted and welded structural bridges, as well as the installation of factories, towers, and chemical, metallurgical, and power generation equipment. Large machinery, lifting equipment, and vehicle assembly operations, as well as occasions with strict requirements for torque and axial tension of threaded fasteners.
電動扭矩扳手螺栓的擰緊操作
Tightening operation of electric torque wrench bolts
1、裝上反力支架，并緊固螺釘。開動主機，使方頭銷孔與反力支架孔相對應，然后裝入扳手套筒，插上銷釘，并用橡膠圈固定。
1. Install the reaction bracket and tighten the screws. Start the main engine so that the square head pin hole corresponds to the reaction support hole, then install the wrench socket, insert the pin, and fix it with a rubber ring.
2、將控制儀的扭矩旋鈕調(diào)到所需扭矩值，將主機正反開關(guān)撥到正轉(zhuǎn)位置，把扳手套筒套在螺紋連接件的六方上。
2. Adjust the torque knob of the control instrument to the desired torque value, turn the forward and reverse switches of the main engine to the forward rotation position, and place the wrench socket on the hexagonal side of the threaded connection.
3、按下電源開關(guān)，扳手啟動。當反力支架力臂靠牢支架時（支點可以是鄰近的一只螺栓或其他可作支點的位置）螺栓開始擰緊。當螺栓扭矩達到預定扭矩時，扳手自動停止，緊固完成，松開電源開關(guān)，進行下一只螺栓的擰緊工作。
3. Press the power switch and start the wrench. When the force arm of the reaction bracket is firmly against the bracket (the fulcrum can be an adjacent bolt or other position that can serve as a fulcrum), the bolt begins to tighten. When the bolt torque reaches the predetermined torque, the wrench automatically stops, the tightening is completed, the power switch is released, and the next bolt tightening work is carried out.
4、扳手自動停止后，靠反力支架的彈性形變力，使支架力臂自動脫離支點，取下扳手。如力臂不能脫離支點時，可撥動正反開關(guān)，點動電源開關(guān)扳手即可取下。
4. After the wrench automatically stops, relying on the elastic deformation force of the counter force bracket, the force arm of the bracket automatically disengages from the fulcrum and the wrench is removed. If the lever arm cannot detach from the fulcrum, the forward and reverse switches can be toggled, and the power switch wrench can be removed by jogging.
