► Fig.15
Hold the tool firmly and place the impact socket over the bolt or nut. Turn the tool on and fasten for the proper fastening time.
The proper fastening torque may differ depending upon 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.

Model DTW800
Proper fastening torque for a standard bolt

Proper fastening torque for high tensile bolt

NOTE: Hold the tool pointed straight at the bolt or nut.
NOTE: Excessive fastening torque may damage the bolt/nut or impact socket. Before starting your job, always perform a test operation to determine the
proper fastening time for your bolt or nut.
NOTE: If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery cartridge.

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. Impact socket
   • Failure to use the correct size impact socket will cause a reduction in the fastening torque.
   • A worn impact 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 of time.

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 low speed will cause a reduction in the fastening torque.

MAINTENANCE

CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.
