[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.5]
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 opera-
tions.
CAUTION:
To prevent damage, do not operate
Forward/Reverse lever until the bit
comes to a complete stop.
Clutch Torque Setting
Adjust the torque to one of the 18 clutch
settings or " " , "
tion.
CAUTION:
• Set the clutch setting at this mark
[Fig.6] before actual operation.
• If the clutch handle cannot be set at
"drilling" mode after driving with clutch
function, set the clutch handle at
position 1 and operate the clutch for a
second.
Speed Selection
Choose a low or high speed to suit the
use. [Fig.7]
The more the variable speed control
trigger is pulled, the higher the speed
becomes.
CAUTION:
• Check the speed selector switch
before use.
• Use in low gear when high torque is
required in operation. (Using in high
gear with high load can cause motor
overload and possible failure.)
• To prevent excessive temperature
increase of the tool surface, do not
operate the tool continuously using
two or more battery packs. The tool
needs cool-off time before switching
to another pack.
• Ensure that air vents on the sides of
the main unit are not blocked during
operation. Covering them can cause
the tool to overheat and motor
damage to occur.
• Do NOT strain the tool (motor). This
may cause damage to the tool.
• Avoid contact with air from vent holes
during operation as under heavy load
this can become hot and potentially
cause injury.
