1、初拧扳手，可用必威西汉姆联官网g1线路也可用手动带响扳手。但无论用哪种扳手施工前都必须进行标定，以便控制初拧扭距值。手动扳手作为终拧工具时，必须每班进行标定，并做好标定记录。
1. The initial tightening wrench can be either an electric wrench or a manual ring wrench. However, no matter which type of wrench is used for construction, calibration must be carried out in order to control the initial tightening torque value. When using a manual wrench as a final tightening tool, it is necessary to calibrate it every shift and keep calibration records.
2、终柠板手：扭剪型高强螺栓是一种自标量型螺栓，因此终拧只须把高强螺栓尾部螺栓头拧掉即可，扳手不用标定。
2. Final tightening wrench: The torsion shear high-strength bolt is a self scalar type bolt, so the final tightening only needs to unscrew the tail bolt head of the high-strength bolt, and the wrench does not need to be calibrated.
3、终拧紧固时应注意，待梅花头全部套入套筒后，才能按下必威西汉姆联官网g1线路开关，若内套筒只套入梅花头尺寸的1/3～1/2长度时按下必威西汉姆联官网g1线路开关，将会造成梅花头打滑，并且影响套筒的使用寿命。
3. When final tightening, attention should be paid to pressing the electric wrench switch only after all the plum blossom heads are inserted into the sleeve. If the inner sleeve is only inserted into 1/3 to 1/2 of the size of the plum blossom head, pressing the electric wrench switch will cause the plum blossom head to slip and affect the service life of the sleeve.
4、紧固时，终拧必威西汉姆联官网g1线路应和构件摩擦面保持垂直，扳手倾斜是很容易导致螺栓尾部梅花头打滑，并易卡壳。
4. When tightening, the final tightening electric wrench should be kept perpendicular to the friction surface of the component. If the wrench is tilted, it can easily cause the end of the bolt to slip and get stuck.
5、使用和保管中应注意防雨、防潮，发现有异常声音应立即停机检查。
5. During use and storage, attention should be paid to rain and moisture prevention. If any abnormal sounds are found, the machine should be immediately shut down for inspection.
