1、初擰扳手，可用電動扳手也可用手動帶響扳手。但無論用哪種扳手施工前都必須進行標定，以便控制初擰扭距值。手動扳手作為終擰工具時，必須每班進行標定，并做好標定記錄。
1. For initial tightening, you can use electric spanner or manual spanner with ring. But no matter what kind of wrench is used, it must be calibrated before construction in order to control the initial torque value. When the manual wrench is used as the final tightening tool, it must be calibrated every shift, and the calibration record must be made.
2、終檸板手：扭剪型高強螺栓是一種自標量型螺栓，因此終擰只須把高強螺栓尾部螺栓頭擰掉即可，扳手不用標定。
2. Final wrench: torsional shear high-strength bolt is a kind of self scalar bolt, so the final screw only needs to screw off the bolt head at the tail of the high-strength bolt, and the wrench does not need to be calibrated.
3、終擰緊固時應注意，待梅花頭全部套入套筒后，才能按下電動扳手開關，若內套筒只套入梅花頭尺寸的1/3～1/2長度時按下電動扳手開關，將會造成梅花頭打滑，并且影響套筒的使用壽命。
3. It should be noted that the electric wrench switch can only be pressed after the ring head is fully inserted into the socket. If the inner socket is only inserted into the 1 / 3 ~ 1 / 2 length of the ring head, pressing the electric wrench switch will cause the ring head to slip and affect the service life of the socket.
4、緊固時，終擰電動扳手應和構件摩擦面保持垂直，扳手傾斜是很容易導致螺栓尾部梅花頭打滑，并易卡殼。
4. When tightening, the final tightening electric wrench should be vertical to the friction surface of the component. The inclination of the wrench is easy to cause the box head of the bolt tail slipping and easy to jam.
5、使用和保管中應注意防雨、防潮，發現有異常聲音應立即停機檢查。
5. Pay attention to rain proof and moisture-proof during use and storage, and stop the machine immediately for inspection in case of abnormal sound.
