NOTE:
The use of the battery in a cold condition (below 0 degree
Centigrade) can sometimes result in the weakened
tightening torque and reduced amount of work. This,
however, is a temporary phenomenon, and returns to
normal when the battery warms up.
7. Using the hook
The hook is used to hang up the power tool to your waist
belt while working.
CAUTION
○ When using the hook, hang up the power tool fi rmly not to
drop accidentally.
If the power tool is dropped, it may lead to an accident.
○ When carrying the power tool with hooked to your waist
belt, do not fi t any bit to the tip of power tool. If the sharp
bit such as drill is fi tted to the power tool when carrying it
with hooked to your waist belt, you will be injured.
○ Install securely the hook. Unless the hook is securely
installed, it may cause an injury while using.
(1) Removing the hook.
Remove the screws fi xing the hook with screw driver.
(Fig. 10)
(2) Replacing the hook and tightening the screws.
Install securely the hook in the groove of power tool and
tighten the screws to fi x the hook fi rmly. (Fig. 11)
8. About Remaining Battery Indicator
When pressing the remaining battery indicator switch,
the remaining battery indicator lamp lights and the
battery remaining power can be checked. (Fig. 12)
When releasing your fi nger from the remaining battery
indicator switch, the remaining battery indicator lamp
goes off . The Table 7 shows the state of remaining
battery indicator lamp and the battery remaining power.
State of lamp Battery Remaining Power
The battery remaining power is
enough.
The battery remaining power is a half.
The battery remaining power is nearly
empty.
Re-charge the battery soonest
possible.
As the remaining battery indicator shows somewhat
diff erently depending on ambient temperature and
battery characteristics, read it as a reference.
NOTE:
○ Do not give a strong shock to the switch panel or break it.
It may lead to a trouble.
○ To save the battery power consumption, the remaining
battery indicator lamp lights while pressing the remaining
battery indicator switch.
9. How to use the LED light
Every time you press the light switch on the switch panel,
the LED light lights or goes off . (Fig. 13)
To prevent the battery power consumption, turn off the
LED light frequently.
CAUTION
Do not expose directly your eye to the light by looking into
the light.
If your eye is continuously exposed to the light, your eye
will be hurt.

Table 7
NOTE:
To prevent the battery power consumption caused
by forgetting to turn off the LED light, the light goes off
automatically in about 15 minutes.
10. Mounting and dismounting of the bit
(1) Mounting the bit
Loosen the sleeve by turning it toward the left (in the
counterclockwise direction as viewed from the front)
to open the clip on the keyless chuck. After inserting a
driver bit, etc., into the keyless drill chuck, and tighten
the sleeve by turning it toward the right (in the clockwise
direction as viewed from the front). (See Fig. 14)
○ If the sleeve becomes loose during operation, tighten it
further.
The tightening force becomes stronger when the sleeve
is tightened additionally.
(2) Dismounting the bit
Loosen the sleeve by turning it toward the left (in the
counterclockwise direction as viewed from the front), and
then take out the bit etc. (See Fig. 14)
NOTE:
If the sleeve is tightened in a state where the clip of the
keyless chuck is opened to a maximum limit, a click
noise may occur. This is the noise that occurs when the
loosening of the keyless chuck is prevented and is not a
malfunction.
CAUTION
When it is no longer possible to loosen the sleeve, use a
vise or similar instrument to secure the bit. Set the clutch
mode between 1 and 11 and then turn the sleeve to the
loose side (left side) while operating the clutch. It should
be easy now to loosen the sleeve.
11. Automatic spindle-lock mechanism
This unit has automatic spindle-lock mechanism for quick
bit changes.
12. Confi rm that the battery is mounted correctly
13. Check the rotational direction
The bit rotates clockwise (viewed from the rear side) by
pushing the R-side of the selector button.
The L-side of the selector button is pushed to turn the bit
counterclockwise. (See Fig. 15) (The
are provided on the push button.)
14. Switch operation
○ When the trigger switch is depressed, the tool rotates.
When the trigger is released, the tool stops.
○ The rotational speed of the drill can be controlled by
varying the amount that the trigger switch is pulled.
Speed is low when the trigger switch is pulled slightly and
increases as the trigger switch is pulled more.
NOTE:
A buzzing noise is produced when the motor is about to
rotate; This is only a noise, not a machine failure.
15. Installing/Removing the side handle
CAUTION
Firmly install the side handle. If loose, the side handle
may gyrate or fall out and cause bodily injury.
(1) Install the side handle so that the protrusions on the main
unit and grooves on the side handle interlock.
Tighten the grip after checking that the side handle is not
riding on the slip prevention protrusion (Fig. 16).
(2) Loosen the grip to remove the side handle.
