The novice has just purchased an electric wrench, and he must be very confused about his use. Simply understand how to use the multi-function electric wrench.

First, the power supply connection First put the host's three-pin plug into the corresponding socket of the controller, and then connect the power cord on the controller to the grid. The green/yellow color core wire is the ground wire. After the work is finished, disassemble in the opposite direction.

Second, the tightening operation of the bolt 1. Install the reaction force bracket and tighten the screws. Start the main machine so that the square pin hole corresponds to the reaction force bracket hole, then insert the wrench sleeve, insert the pin, and fix it with a rubber ring. 2. Adjust the torque knob of the controller to the required torque value, turn the main switch of the main unit to the forward position, and place the Autojare' electric wrench sleeve on the hexagonal part of the threaded connection. 3. Press the power switch and the wrench starts. When the reaction force arm is pressed against the fulcrum (the fulcrum can be a nearby bolt or other position that can be used as a fulcrum), the bolt starts to tighten. When the bolt torque reaches the predetermined torque, the wrench automatically stops, the tightening is completed, and the power switch is released to perform the fastening work of the next bolt. 4. After the wrench is automatically stopped, rely on the elastic deformation force of the reaction force bracket to make the bracket arm automatically disengage from the fulcrum and remove the wrench. If the arm cannot be disengaged from the fulcrum, you can toggle the forward and reverse switch, jog the power switch, and the wrench can be removed.

Third, the bolt removal operation When the wrench is removed (reverse), the operation method is the same as the tightening operation, just turn the forward and reverse switch to the reverse position, and the bolt is unloaded to prevent the power switch from opening. Fourth, the choice and adjustment of torque 1, the user can choose the appropriate size of the multi-purpose electric wrench in the range of 100---3500Nm. 2. There is a “torque adjustment” knob on the panel of the controller, which is engraved with 0-100 scale value to adjust the torque. 3. Adjustment method: The product is shipped with torque test data card for the user to reference. The user can select a certain scale value according to the required torque and tighten the bolt according to the operation method of tightening the bolt. Use a force wrench or other force measuring instrument to measure the actual torque value of the bolt. If the torque value is too high, adjust the torque to the low scale. If the torque value is low, adjust to the high scale value. The exact torque value required.
