Changing the impact force

►Fig.7: 1. Hard 2. Soft 3. A mode 4. Changed in three

steps 5. Button

You can change the impact force in three steps: hard,

soft, and A mode.

This allows a tightening suitable to the work.

Everytimethebuttonispressed,thenumberofblows

changes in three steps.

“Amode(assistmode)”isaneasy-to-usemodefor

driving screws with good control.

In this mode, the tool drives a screw with low-speed

rotationatrst.Afterthetoolstartstoimpact,therota-

tion speed increases and reaches the maximum speed.

Forapproximatelyoneminuteafterreleasingtheswitch

trigger, the impact force can be changed.
