The correct operation method for electric torsion wrench:



Before adjusting the shear wrench or replacing accessories and spare parts, please cut off the power. When disassembling or installing the inner and outer sleeves, do not let foreign objects enter the tool. Firstly, push out the two screws on the outer sleeve, the outer sleeve, and the inner sleeve from the spring installed in the tool, press the bolts and remove the inner sleeve. Be careful not to let the inner sleeve fall off during the disassembly process, and do not remove the inner sleeve spring, push tooth rod, and push tooth rod spring from the tool. Secure the inner sleeve with the bolt facing upwards. Then place the outer sleeve on the inner sleeve and secure it with the bolts. Insert the outer sleeve and inner sleeve into the tool, and rotate the inner sleeve clockwise and counterclockwise alternately until there is no gap between the outer sleeve and the tool.


Daily maintenance methods for electric torque wrench:
