Bit Installation

Pinch points:
• Due to possibility of accidental
operation, remove battery when
changing bits.
• Keep hands away from spinning
parts while tool is in operation.
Failure to observe these warnings
could result in injury.
This tool is equipped with a keyless drill chuck. When
attaching or removing a bit, disconnect the battery
pack from the tool and place the switch in the center
position (switch lock).
Attaching the Bit
Insert the bit and turn the lock collar clockwise (viewed
from the front) to tighten firmly until it stops clicking.
Removing the Bit
Turn the lock collar counterclockwise (viewed from the
front), and then remove the bit.
Lock collar
Note: If excessive play occurs in the chuck, secure the
drill in place and (1) open the chuck jaws by turning
the lock collar, and (2) tighten the screw (left-handed
screw) with a screwdriver by turning it counterclock-
wise (viewed from the front).

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.
