7 ENGLISHCAUTION: Always check the direction ofrotation before operation.CAUTION: Use the reversing switch only afterthe tool comes to a complete stop. Changing thedirection of rotation before the tool stops may dam-age the tool.CAUTION: When not operating the tool,always set the reversing switch lever to the neu-tral position.This tool has a reversing switch to change the directionof rotation. Depress the reversing switch lever from theA side for clockwise rotation or from the B side for coun -terclockwise rotation.When the reversing switch lever is in the neutral posi -tion, the switch trigger cannot be pulled.Changing the impact force41235Ź 1. Hard 2. Soft 3. A mode 4. Changed in three steps5. ButtonYou 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 blowschanges in three steps.“A mode (assist mode)” is an easy-to-use mode fordriving screws with good control.In this mode, the tool drives a screw with low-speedrotation at irst. After the tool starts to impact, the rota -tion speed increases and reaches the maximum speed.For approximately one minute after releasing the switchtrigger, the impact force can be changed.Impact force grade displayedon panelMaximum blows Purpose Example of applicationHard 3,900 min-1 (/min) Tightening when force andspeed are desired.Tightening wood screws,tightening bolts.Soft 1,600 min-1 (/min) Tightening with less force toavoid screw thread breakage.Tightening sash screws, tight-ening small screws such as M6.A mode 3,900 min-1 (/min) Tightening screws with bettercontrol.Tightening long screws.NOTE: A mode is available only when the tool rotates clockwise. When rotating counterclockwise in A mode, theimpact force and speed are the same as hard mode.NOTE: When all lamps on the switch panel go out, the tool is turned off to save the battery power. The impact forcegrade can be checked by pulling the switch trigger to the extent that the tool does not operate.NOTE: While pulling the switch trigger, the impact force grade cannot be changed.
