the workpiece to be fastened, etc. Before starting your job, always perform a test operation to
determine the proper fastening time for your bolt or nut.
1. Hold the tool rmly and place the socket over the bolt or nut.
2. Turn the tool on and fasten the bolt or nut to the proper torque.
3. After fastening, always check the torque with a torque wrench.
NOTE: Hold the tool straight along the axis of the bolt or nut.
NOTE: Excessive fastening torque may damage the bolt/nut or socket.
