Electric torque wrench is mainly used for fastening large hexagon high-strength bolts, so how to use electric torque wrench?

一、使用方法：

1、 Usage:

1、扭矩调节:

1. Torque adjustment:

先将机器插头插入插座然后按动开关，用标配小平口螺丝刀调节扭矩旋钮，顺时针旋动增加，逆时针减小，长按快速增加，再长按快速减小，以此循环增减。

First, insert the machine plug into the socket, then press the switch, use the standard small flat screwdriver to adjust the torque knob, turn clockwise to increase, anticlockwise to decrease, long press to increase rapidly, then long press to decrease rapidly, so as to increase or decrease circularly.

2、正反转调节:

2. Positive and negative adjustment:

旋动机器后端旋钮使箭头指向R挡为拧紧螺栓，指向L挡为拆卸螺栓。

Turn the rear knob of the machine to make the arrow point to R gear to tighten the bolt, and point to l gear to remove the bolt.

二、螺栓的拧紧操作：

2、 Tightening operation of bolts:

1、装上所需大小的套筒并紧固螺钉。

1. Fit the sleeve of the required size and tighten the screws.

2、设定所需扭矩值,将扳手后端旋钮旋R挡,把扳手套筒套在螺纹连接件的六方上。

2. Set the required torque value, turn the knob at the back end of the wrench to R gear, and put the wrench socket on the hexagon of the threaded connector.

3、按下电源开关，扳手启动。当外套筒反力臂靠牢支点时(支点是邻近的一只螺栓或其他可做支点的位置)螺栓开始拧紧，当螺栓扭矩达到预定扭矩时，扳手自动停止，紧固完成，放开电源开关，进行下一只螺栓的紧固工作。

3. Press the power switch to start the wrench. When the reaction arm of the outer sleeve is close to the fulcrum (the fulcrum is a nearby bolt or other position that can be used as a fulcrum), the bolt starts to be tightened. 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 is tightened.

4、扳手自动停止后，靠反力臂的弹性形变力，使力臂自动脱离支点，取下扳手，如力臂不能脱离支点时，可旋动旋钮L挡，点动电源开关，扳手即可下。

4. After the spanner stops automatically, the force arm will be automatically separated from the fulcrum by the elastic deformation force of the reaction arm. Take down the spanner. If the force arm cannot be separated from the fulcrum, turn the knob to the L gear, click the power switch, and the spanner can be removed.

三、螺栓的拆卸操作：

3、 Removal of bolts:

扳手在拆卸螺栓(反转)时,其操作方法与拧紧操作相同,只需将旋钮旋L挡按动开关,螺栓卸松后放开电源开关。

When the wrench is removing the bolt (reverse rotation), the operation method is the same as the tightening operation. Just turn the knob to the L position and press the switch. Release the power switch after the bolt is loosened.

四、扭矩的选择与调节

4、 Selection and adjustment of torque
