Speed change
► Fig.7: 1. Speed change lever
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.
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.
NOTE: The tool automatically stops if you keep pull-
ing the switch trigger for about 6 minutes.
CAUTION: Do not use the speed change lever
while the tool is running. The tool may be damaged.

operation
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.
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
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 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.
CAUTION: Always check the direction of
rotation before operation.
CAUTION: When you change the position
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.
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.
► Fig.8: 1. Action mode changing ring 2. Adjusting
ring 3. Graduation 4. Arrow
This tool has three action modes.
CAUTION: When not operating the tool,
always set the reversing switch lever to the neu-
tral position.
•
Drilling mode (rotation only)
•
Hammer drilling mode (rotation with
hammering)
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.
•
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.9: 1. Action mode changing ring 2. Adjusting
ring 3. Graduation 4. Arrow
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.
The fastening torque can be adjusted in 21 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 21.
