VI. OPERATION
[Main Body]
Switch Operation
1.The speed increases with the amount of depression of the trigger. When beginning work, depress the trigger slightly to start the rotation slowly.
2.A feedback electronic controller is used to give a strong torque even in low speed.
3.The brake operates when the trig- ger is released and the motor stops immediately.
NOTE:
•When the brake operates, a brak- ing sound may be heard. This is normal.
•Sparks from the motor brush may be visible through the body vent holes on the back of the tool during switching and braking due to the load imposed on the motor. This does not indicate a problem with the tool.
