M14-m27 constant torque electric wrench is composed of host and controller. The host adopts double insulated single-phase series motor and reduction mechanism, which has novel structure, small volume, light weight and no harm. Due to the static torsion structure, the operation is stable, no vibration, no impact, low noise, and the operator is not affected by the counter torque, so the labor intensity is low. Rated voltage 220V50 / 60Hz, accuracy ± 5%.

M14-M27定扭矩电动扳手螺栓的拧紧操作

Tightening operation of m14-m27 constant torque electric wrench bolt

1、装上反力支架，并紧固螺钉。开动主机，使方头销孔与反力支架孔相对应，然后装入扳手套筒，插上销钉，并用橡胶圈固定。

1. Install the reaction support 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、将控制仪的扭矩旋钮调到所需扭矩值，将主机正反开关拨到正转位置，把扳手套筒套在螺纹连接件的六方上。

2. Adjust the torque knob of the controller to the required torque value, turn the forward and reverse switch of the host to the forward position, and put the wrench socket on the hexagon of the threaded connector.

3、按下电源开关，扳手启动。当反力支架力臂靠牢支架时（支点可以是邻近的一只螺栓或其他可作支点的位置）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，松开电源开关，进行下一只螺栓的拧紧工作。

3. Press the power switch and the wrench starts. When the force arm of the reaction support is firmly against the support (the fulcrum can be an adjacent bolt or other position that can be used as a fulcrum), the bolt begins to tighten. When the bolt torque reaches the predetermined torque, the wrench will automatically stop, the tightening is completed, loosen the power switch and tighten the next bolt.

4、扳手自动停止后，靠反力支架的弹性形变力，使支架力臂自动脱离支点，取下扳手。如力臂不能脱离支点时，可拨动正反开关，点动电源开关扳手即可取下。

4. After the wrench stops automatically, the force arm of the support will automatically disengage from the fulcrum by the elastic deformation force of the reaction support, and then remove the wrench. If the force arm cannot be separated from the fulcrum, turn the positive and negative switch and click the power switch wrench to remove it.

M14-M27定扭矩电动扳手扭矩的选择与调节

Torque selection and adjustment of m14-m27 constant torque electric wrench

1、用户可在50-3500N.m的范围内任意选择相应规格的 可以手动调节力矩的电动数显力矩扳手。

1. The user can arbitrarily select the electric digital display torque wrench with corresponding specifications that can manually adjust the torque within the range of 50-3500n. M.

2、控制仪面板上有“扭矩调解旋钮”。刻有0-10个刻度值。细调旋钮的作用是在粗调两档之间进行调节补偿，以提高扭矩控制精度。（见后页）

2. There is a "torque adjustment knob" on the control instrument panel. Engraved with 0-10 scale values. The function of fine adjustment knob is to adjust and compensate between coarse adjustment and two gears, so as to improve the torque control accuracy. (see next page)

3、调节方法：产品出厂时带有扭矩测试数据卡片，供用户标定时参考，用户可根据所需扭矩选择某一刻度值，按拧紧螺栓的操作方法，拧紧螺栓，用测力扳手或其它测力仪器测出螺栓的实际扭矩值，若扭矩相差较小，可用细调加以补偿，若相差较大，可将粗调向上或向下调一档，反复几次即可获得所需扭矩值。

3. Adjustment method: the product is delivered with a torque test data card for users' reference during calibration. Users can select a scale value according to the required torque, tighten the bolt according to the operation method of tightening the bolt, and measure the actual torque value of the bolt with a force measuring wrench or other force measuring instruments. If the torque difference is small, it can be compensated by fine adjustment. If the difference is large, The coarse adjustment can be up or down by one gear, and the required torque value can be obtained by repeating it several times.

Precautions for operation of m14-m27 constant torque electric wrench

1、螺栓直径的大小对控制精度有一定的影响，施工中应用相同型号的螺栓连接付来标定扭矩值，而且使用一段时间后还应进行检验校定。

1. The size of bolt diameter has a certain impact on the control accuracy. During construction, the same type of bolt connection pair shall be used to calibrate the torque value, and inspection and calibration shall be carried out after use for a period of time.

2、工作前应开机空转3-5分钟。操作中如发现电机火花大，声音异常，扭矩不稳定时，应立即停机检查，切勿带病工作。

2. Start up and idle for 3-5 minutes before operation. In case of large spark, abnormal sound and unstable torque of the motor during operation, stop the machine immediately for inspection and do not work with disease.

3、定期清洗和更换油脂，一般在工作5000次后，应进行一次清洗加油，以延长使用寿命。

3. Clean and replace the grease regularly. Generally, after 5000 times of operation, clean and refuel once to prolong the service life.

4、主机上的电源开关，碳刷，控制仪上的保险丝等均属易损件，容易引起故障，应经常检查，及时更换。

4. The power switch, carbon brush and fuse on the control instrument on the host are vulnerable parts, which are easy to cause faults. They should be checked frequently and replaced in time.

5、使用中如发现工具上的螺钉松动，应及时紧固。

5. If the screw on the tool is found to be loose during use, it shall be tightened in time.

6、搬运工具时不可提拉电缆线，并注意轻拿轻放，防止震动和摔碰。不用时应放在通风干燥处。如发现受潮应及时进行干燥处理。不可与酸、碱等有害物质气体接触或存放在一起。

6. Do not lift the cable when handling tools, and pay attention to handle it gently to prevent vibration and collision. When not in use, it should be placed in a ventilated and dry place. If moisture is found, it shall be dried in time. Do not contact or store with acid, alkali and other harmful substances and gases.

Precautions for m14-m27 constant torque electric wrench operation

（需特别注意）

(special attention required)

1、接通电源前应先查看电源电压是否与本产品铭牌相符，是否有接地装置。当电源电压超出+10%时应采取稳压措施，否则会影响控制精度。接地不良易造成事故。

1. Before connecting the power supply, check whether the power supply voltage is consistent with the nameplate of the product and whether there is a grounding device. When the power supply voltage exceeds + 10%, voltage stabilizing measures shall be taken, otherwise the control accuracy will be affected. Poor grounding is easy to cause accidents.

2、工具使用的环境温度为-10℃-40℃，过高过低都会影响控制精度。

2. The ambient temperature of the tool is - 10 ℃ - 40 ℃, too high or too low will affect the control accuracy.

3、被拧螺栓的初始扭矩不得大于工具的额定扭矩的70%。螺栓达到额定扭矩后不得重拧。

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、工具用于拆卸螺栓时，其扭矩不得大于额定扭矩值。一般情况下，不是本扳手拧紧的或锈蚀严重的螺栓，不宜用本扳手拆卸，以免造成工具损坏。

4. When the tool is used to remove the bolt, its torque shall not be greater than the rated torque. Generally, the bolts that are not tightened or seriously rusted by this wrench should not be removed with this wrench to avoid tool damage.

5、变换旋转方向时，必须待电机停止转动后进行，严禁在运转中拨动正反开关。

5. When changing the rotation direction, it must be carried out after the motor stops rotating. It is strictly prohibited to toggle the positive and negative switches during operation.

6、当扳手自动停止后即可松开开关（如果不断开开关，过5秒钟扳手就会自行启动）待4-5秒后再进行开动扳手，否则扳手不能启动。

6. When the wrench stops automatically, loosen the switch (if the switch is not opened, the wrench will start automatically after 5 seconds). Start the wrench after 4-5 seconds, otherwise the wrench cannot start.
