Hold the tool firmly and place the point of the driver bit in the screw head. Apply for- ward pressure to the tool to the extent that the bit will not slip off the screw and turn the tool on to start operation.

NOTE :

0 Use the proper bit for the head of the screw that you wish to use. Hold the tool pointed straight a t the screw.

0 If you fasten the screw for a time longer than shown in the figures above, the screw or the screw or the point of the driver. bit may be overstressed, stripped, damaged, etc. Before starting your job, always perform a test operation to verify the adequate fasten- ing time for your screw. When fastening a machine screw in a steel plate, the proper fastening torque can be obtained in an extremely short time (approx. 0.1 -0.2 seconds). Turn the tool off as soon as the impact sound is heard.

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

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, voltage will drop and the fastening torque will be reduced.

2.Drive bit or socket bit

Failure to use the correct size driver bit or socket bit will cause a reduction in the fastening torque.
