III. OPERATION
EN
WARNING!
• Do not inhale smoke emitted from the
main unit or battery pack as it may be
harmful.
[Main Unit]
CAUTION
When storing or carrying the tool, set the
Forward/Reverse lever to the center
position (switch lock).
NOTE:
Exercise caution to ensure no objects
come into contact with the tool's
trigger switch.
If an object comes into contact with
the tool's trigger switch, even while
the Forward/Reverse lever is in the
center position (locked), a small
amount of electric current may
continue flowing, which may cause an
excessive discharge from the battery
pack and subsequent battery pack
failure.
Switch and Forward/Reverse Lever
Operation [Fig.6]
1. Push the lever for forward or reverse
rotation. Check the direction of the
lever before using.
2. Depress the trigger switch slightly to
start the tool slowly.
3. Speed will increase by pressing the
trigger. The tool stops working
immediately by releasing the trigger.
4. When done with an application, lock the
switch by centering the lever.
NOTE:
When the brake operates, a braking
sound may be heard. This is normal.
CAUTION:
When operating the tool by pulling the
trigger, there may be a momentary lag
before rotation starts. This does not
signal a malfunction.
* This lag occurs as the tool's circuitry
starts up when the trigger is pulled for
the first time after installing a battery
pack or after the tool has not been
used for at least 1 minute (or at least
5 minutes when the LED is on).
Rotation will start without any lag
during second and subsequent
operations.
CAUTION:
To prevent damage, do not operate
Forward/Reverse lever until the bit
comes to a complete stop.
