Lighting up the front lamp
► Fig.5: 1. Lamp
CAUTION:
Do not look in the light or see the
source of light directly.
Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
The lamp goes out approximately 10 seconds after
releasing the switch trigger.
NOTE: When the tool is overheated, the tool stops
automatically and the lamp starts flashing. In this
case, release the switch trigger. The lamp turns off in
one minute.
NOTE: Use a dry cloth to wipe the dirt off the lens of
the lamp. Be careful not to scratch the lens of lamp, or
it may lower the illumination.
Reversing switch action
► Fig.6: 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
direction of rotation before the tool stops may dam-
age the tool.
CAUTION:
When not operating the tool,
always set the reversing switch lever to the neu-
tral 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.

To change the speed, switch off the tool first. Push
the speed change lever to display "2" for high speed
or "1" for low speed but high torque. Be sure that the
speed change lever is set to the correct position before
operation.
If the tool speed is coming down extremely during the
operation with display "2", push the lever to display "1"
and restart the operation.
Selecting the action mode
CAUTION:
your desired mode mark. If you operate the tool
with the ring positioned halfway between the
mode marks, the tool may be damaged.
CAUTION:
from " " to other modes, it may be a little dif-
ficulty to slide the action mode changing ring. In
this case, switch on and run the tool for a second
at the " " position, then stop the tool and slide
the ring to your desired position.
► Fig.8: 1. Action mode changing ring 2. Adjusting
ring 3. Graduation 4. 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.
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 applica-
tion. The following shows the rough guide of the rela-
tionship between the screw size and graduation.
