Remove the spindle of the socket wrench and place the steel wire insert into the socket from the socket groove (groove upwards)** Use your fingers to prevent the steel wire sleeve from moving and insert it into the core shaft. Use the groove at the end of the core shaft to clamp the installation handle of the steel wire sleeve.

The third step is to rotate the spindle and screw the steel wire insert into the guide thread of the sleeve installation tool. Use the guide thread to pre shrink the end of the steel wire insert until it is flush with the end face of the guide thread (do not let the steel wire insert unscrew from the guide thread).
