NOTE:

When fastening screw M8 (5/16”) or smaller, carefully adjust pressure on the switch trigger so that the screw is not damaged.

Hold the tool pointed straight at the bolt or nut.

Excessive fastening torque may damage the bolt/nut or socket. Before starting your job, always perform a test operation to determine the proper fastening time for your bolt or nut. Especially for the bolt smaller than M8 (5/ 16”), perform the above test operation to prevent the trouble on socket or bolt, etc.
