1、裝上反力支架，并緊固螺釘。開動主機(jī)，使方頭銷孔與反力支架孔相對應(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 host, align the square pin hole with the reaction bracket 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 controller to the desired torque value, turn the positive and negative switches of the host to the positive rotation position, and insert the wrench socket onto the hexagonal threaded connector.

3、按下電源開關(guān)，扳手啟動。當(dāng)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(dāng)螺栓扭矩達(dá)到預(yù)定扭矩時，扳手自動停止，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 to activate the wrench. When the force arm of the reaction bracket is firmly attached to 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 stops automatically, the elastic deformation force of the reaction bracket causes the bracket arm to automatically detach from the fulcrum and remove the wrench. If the lever arm cannot detach from the pivot point, the forward and reverse switches can be turned, and the power switch wrench can be used to remove it.
