Battery protection system
The battery cartridge is equipped with the protection
system, which automatically cuts off the output power
for its long service life.
The tool stops during operation when the tool and/or
battery are placed under the following situation. This is
caused by the activation of protection system and does
not show the tool trouble.
•
When the tool/battery is overloaded:
At this time, release the switch trigger, remove the
battery cartridge and remove causes of overload
and then pull the switch trigger again to restart.
• When battery cells get hot:
If any operation of the switch trigger, the motor will
remain stopped. At this time, stop use of the tool
and cool the battery cartridge.
• When the remaining battery capacity gets low:
If you pull the switch trigger, the motor runs again
but stops soon. In this case, to prevent over dis -
charge, remove the battery cartridge from the tool
and charge it.
Switch action
► Fig.2: 1. Switch trigger
CAUTION:
Before installing the battery car-
tridge into the tool, always check to see that the
switch trigger actuates properly and returns to
the "OFF" position when released.
To start the tool, simply pull the switch trigger. Tool
speed is increased by increasing pressure on the switch
trigger. Release the switch trigger to stop.
Reversing switch action
► Fig.3: 1. Reversing switch lever
CAUTION:
Always check the direction of
rotation before operation.
CAUTION:
Use the reversing switch only after
the tool comes to a complete stop. Changing the direc-
tion of rotation before the tool stops may damage the tool.
CAUTION:
When not operating the tool, always
set the reversing switch lever to the neutral position.
This tool has a reversing switch to change the direction
of rotation. Depress the reversing switch lever from the
A side for clockwise rotation or from the B side for coun -
terclockwise rotation.
When the reversing switch lever is in the neutral posi-
tion, the switch trigger cannot be pulled.
Speed change
► Fig.4: 1. Speed change lever
CAUTION:
Always set the speed change lever
fully to the correct position. If you operate the tool with
the speed change lever positioned halfway between the
"1" side and "2" side, the tool may be damaged.
CAUTION:
Do not use the speed change lever
while the tool is running. The tool may be damaged.

and restart the operation.
Selecting the action mode
CAUTION:
Always set the ring correctly to
your desired mode mark. If you operate the tool
with the ring positioned halfway between the
mode marks, the tool may be damaged.

3. Arrow
This tool has three action modes.
• Drilling mode (rotation only)
• Hammer drilling mode (rotation with hammering)
• Screwdriving mode (rotation with clutch)
Select one mode suitable for your work. Turn the
action mode changing ring and align the mark that you
selected with the arrow on the tool body.
Adjusting the fastening torque
► Fig.6: 1. Adjusting ring 2. Graduation 3. Arrow
The fastening torque can be adjusted in 16 levels by
turning the adjusting ring. Align the graduations with the
arrow on the tool body. You can get the minimum fas -
tening torque at 1 and maximum torque at 16.
Before actual operation, drive a trial screw into your
material or a piece of duplicate material to determine
which torque level is required for a particular application.
ASSEMBLY
CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.
