The speed increases with theamount of depression of the trigger.When beginning work, depress thetrigger slightly to start the rotationslowly.2. A feedback electronic controller isused to give a strong torque even inlow speed.3. The brake operates when the trig-ger is released and the motor stopsimmediately.Note: When the brake operates, abraking sound may be heard.This is normal.Forward/Reverse lever Operation(Forward ( ), Switch lock, Reverse ( ))CAUTION: Do not operate Forward/Reverse lever until thechuck comes to a com-plete stop. Shifting duringrotation of the chuck maydamage the tool.Forward Rotation Switch Operation1. For forward rotation, set the lever toforward.2. Depress the trigger switch slightly tostart the tool slowly.3. The speed increases with theamount of depression of the triggerfor efficient tightening of screws anddrilling. The brake operates and thechuck stops immediately when thetrigger is released.4. After use, set the lever to its centerposition (switch lock).Reverse Rotation Switch Operation1. For reverse rotation, set the lever toreverse. Check the direction of rota-tion before use.2. Depress the trigger switch slightly tostart the tool slowly.3. After use, set the lever to its centerposition (switch lock).Clutch Torque SettingAdjust the torque to one of the 5 pos-sible settings or “ “, “ “ position tothe job.CAUTION: Test the setting beforeactual operation.Set the scale at this line.Reference for Adjusting TorqueScale Torque Use1 Approx. 1.0 Nm(10 k f-cm or 8.7 in-lbs.)For driving terminalscrews2 Approx. 1.5 Nm(15 k f-cm or 13.0 in-lbs.)For driving machinescrews3 Approx. 2.5 Nm(25 k f-cm or 21.7 in-lbs.)For driving screwsinto soft materials4 Approx. 3.4 Nm(35 k f-cm or 30.5 in-lbs.)
