One-Shot Impact Function

This function helps adjust the screw head flush to the material surface.

The driver rotates half round∗ and auto- matically stops each time the trigger switch is depressed while tightening a screw. The driver will give impact about 5 times and automatically stop while tightening a bolt even though the trigger switch is depressed. The one-shot impact function is also available in reverse rota- tion. The impact force is set by the impact power mode select and digital clutch set- tings.
