Operation—Power Tool (cont'd)

Variable Speed Trigger Operation

1. The speed increases with the amount of depres-
sion 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 trigger is released
and the motor stops immediately.
Note: When the brake operates, a braking sound may
be heard. This is normal.

Forward/Reverse Switch Operation

• If the bit becomes jammed, immediately release
the trigger to prevent an overload which can
damage the battery pack or motor. Use reverse
motion to loosen jammed bits.
• To prevent damage, do not operate Forward/
Reverse switch until the bit comes to a complete
stop.
• Do NOT operate the Forward/Reverse switch
when the trigger switch is on. The battery will dis-
charge rapidly and damage to the unit may occur.
