Tightening operation of bolts

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. 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. 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. 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.
