BATTERY REMOVAL/INSTALLATION

1. Battery removal
Hold the handle tightly and push the battery latch
to remove the battery (see Figs. 1 and 2).
CAUTION
Never short-circuit the battery.
2. Battery installation
Insert the battery while observing its polarities (see
Fig. 2).
CHARGING
Before using the driver drill, charge the battery as follows.
1. Insert the battery in the charger.
Position the battery so that the nameplate faces
toward the nameplate of the charger and press in
the battery until it comes into contact with the
bottom plate. (See Figs. 1 and 3.)
2. Connect the charger power cord to the AC outlet.
Connecting the power cord will turn on the charger
(the pilot lamp lights).
CAUTION
If the pilot lamp does not light, pull out the power
cord from the AC outlet and check the battery
mounting condition.
About 1 hour is required to fully charge the battery
at a temperature of about 20°C. The pilot lamp goes
off to indicate that the battery is fully charged.
CAUTION
If the battery is heated due to direct sunlight, etc.,
just after operation, the charger pilot lamp may
not light. At that time cool the battery first, then
start charging.
3. Disconnect the charger power cord from the AC
outlet.
4. Hold the charger tight and pull out the battery.

HOW TO USE
CAUTIONS
After inserting a driver bit, etc. into the keyless drill
chuck, firmly grasp the ring and tighten the sleeve
by turning it toward the right (in the clockwise
direction as viewed from the front). (See Fig. 4)
If the sleeve becomes loose during operation, tighten
it further. The tightening force becomes stronger
when the sleeve is tightened.
Firmly grasp the ring and loosen the sleeve by
turning it toward the left (in the counter-clockwise
direction as viewed from the front). (See Fig. 4)
When the selector lever is set to
clockwise when viewed from the drill rear. When
set to , the drill rotates counterclockwise. (See
L
Fig. 5) (The and
L
body)
CAUTION
When the trigger switch is depressed, the se-
lector lever cannot be moved. Always release
the trigger switch to move the selector lever.
Operate the shift knob to change the rotational
speed. Move the shift knob in the direction of the
arrow. (See Figs. 6 and 7)
When the shift knob is set to "LOW", the drill
rotates at a low speed. When set to "HIGH", the
drill rotates at a high speed. If the shift knob cannot
be moved smoothly, clasp the drill chuck by hand
and rotate the spindle slightly.
CAUTIONS
When changing the rotational speed with the
shift knob, confirm that the switch is off. Chang-
ing the speed while the motor is rotating will
damage the gears.
To mesh the gears, certainly move the shift knob
so that the "LOW" or "HIGH" mark can fully be
seen. (See Figs. 6 and 7)
