3. Charging
The pilot lamp goes off to indicate that the battery
is fully charged.
(1) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown
in Table 2.
NOTE
The battery charging time becomes longer when a
temperature is low or the voltage of the power
source is too low.
When the pilot lamp does not go off even if more
than four hour has passed after start of the charging,
stop the charging and contact your HITACHI
AUTHORIZED SERVICE CENTER.
4. Disconnect the charger's power cord from the AC
outlet.
5. Hold the charger firmly and pull out the battery.
Regarding electric discharge in case of new batteries,
etc.
As the internal chemical substance of new batteries
and batteries that have not been used for an
extended period is not activated, the electric
discharge might be low when using them the first
and second time. This is a temporary phenomenon,
and normal time required for recharging will be
restored by recharging the batteries 2-3 times.
How to make the batteries perform longer.
(1) Recharge the batteries before they become
completely exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the
electric current, the battery may be damaged and
its life will become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the
battery and recharge it after it has cooled for a
while.
CAUTION
If the battery has been heated right after operation
(or due to sunlight, etc.), the charger's pilot lamp
may not light in red. In such a case, first let the
battery cool, than start charging.

PRIOR TO OPERATION

1. Mounting and dismounting of the bit
Before mounting the bit, confirm that the switch is
locked.
For keyless chuck
(1) Mounting the bit
After inserting a driver bit, etc. into the keyless drill
chuck, firmly grasp the ring and tighten the sleeve
by turning ti 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.
(2) Dismounting the bit
Firmly grasp the ring and loosen the sleeve by
turning it toward the left (in the counter-clockwise
directions as viewed from front). (See Fig. 4)
For chuck wrench
Always use chuck wrench to insall a driver bit or
drill securely. As three chuck wrench holes are
provided, tighten the chuck evenly. (See Fig. 5)
NOTE
A chuck wrench is attached to the center of the
body. If it is pulled toward you, it will be detached.
After using the wrench, attach it to the body se-
curely.
2. Confirm that the battery is mounted correctly.
3. Check the rotational direction
When the selector lever is set to
clockwise when viewed from the drill rear. When
set to , the drill rotates counterclockwise (see
L
Fig. 6). (The and
L
the body.)
CAUTION
When the trigger switch is depressed, the selector
lever cannot be moved. Always release the trigger
switch to move the selector lever.
4. Change rotation speed
Operate the shift knob to change the rotational
speed. Move the shift knob in the direction of the
arrow (see Figs. 7 and 8).
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 and locked.
Changing 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. 7 and 8).
5. Change the speed depending upon uses.
