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(huì)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(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 retighten the bolt 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 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(shí)，必須待電機(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(dāng)扳手自動(dòng)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(huì)自行啟動(dòng)）待4-5秒后再進(jìn)行開動(dòng)扳手，否則扳手不能啟動(dòng)。

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(dòng)力矩扳手是裝配螺紋件及螺栓的機(jī)械化施工工具，具有自動(dòng)控制扭矩功能。應(yīng)用于栓焊結(jié)構(gòu)橋梁的架設(shè)，廠房、塔架及化工、冶、發(fā)電設(shè)備的安裝。大型機(jī)械、起重設(shè)備和車輛裝配作業(yè)，以及對(duì)螺紋緊固件的扭矩及軸向拉力有嚴(yán)格要求的場(chǎng)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(dòng)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(dòng)主機(jī)，使方頭銷孔與反力支架孔相對(duì)應(yīng)，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(jī)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(dòng)。當(dāng)反力支架力臂靠牢支架時(shí)（支點(diǎn)可以是鄰近的一只螺栓或其他可作支點(diǎn)的位置）螺栓開始擰緊。當(dāng)螺栓扭矩達(dá)到預(yù)定扭矩時(shí)，扳手自動(dòng)停止，緊固完成，松開電源開關(guān)，進(jìn)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(dòng)停止后，靠反力支架的彈性形變力，使支架力臂自動(dòng)脫離支點(diǎn)，取下扳手。如力臂不能脫離支點(diǎn)時(shí)，可撥動(dòng)正反開關(guān)，點(diǎn)動(dòng)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.
