To install the socket, push it onto the anvil of the tool until it locks into place. To remove the socket, simply pull it off.

OPERATION

The proper fastening torque may differ depending on the kind or size of the bolt, the material of the workpiece to be fastened, etc. The relation between fastening torque and fastening time is shown in the figures.

Hold the tool firmly and place the socket over the bolt or nut. Turn the tool on and fasten it for the proper fastening time.

NOTE:

• When fastening screw M8 (5/16″) or smaller, carefully adjust the pressure on the switch trigger so that the screw is not damaged.
• Hold the tool pointed straight at the bolt or nut without applying excessive pressure on the tool.
• 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 trouble on the socket or bolt, etc.
• If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for more than 15 minutes before proceeding with a fresh battery.

The fastening torque is affected by a wide variety of factors including the following. After fastening, always check the torque with a torque wrench.

1. When the battery cartridge is discharged almost completely, the voltage will drop and the fastening torque will be reduced.
2. Socket
   • Failure to use the correct size socket will cause a reduction in the fastening torque.
   • A worn socket (wear on the hex end or square end) will cause a reduction in the fastening torque.
3. Bolt
   • Even though the torque coefficient and the class of bolt are the same, the proper fastening torque will differ according to the diameter of the bolt.
   • Even though the diameters of bolts are the same, the proper fastening torque will differ according to the torque coefficient, the class of bolt, and the bolt length.
4. The use of the universal joint or the extension bar somewhat reduces the fastening force of the impact wrench. Compensate by fastening for a longer period.
5. The manner of holding the tool or the material of the driving position to be fastened will affect the torque.
6. Operating the tool at a low speed will cause a reduction in the fastening torque.
