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 t he charger
(the pilot lamp lights up).
CAUTION
If the pilot lamp does not light up 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.
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.
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.

PRIOR TO OPERATION

1. Setting up and checking the work environment
Check if the work environment is suitable by follow-
ing the precautions.
HOW TO USE
CAUTION:
Before installing batteries, make sure that the
reversing switch is in neutral position. (See Fig. 4.)
1. Confirm the cap position (see Fig. 5)
The tightening power of this unit can be adjusted
according to the cap position, at which the cap is
set.
(1) For using the unit as a screw driver, set the cap
white line to one of the numerals "1" to "5" on
the outer frame.
(2) For use as a drill, set the white line at the drill mark
" " (see Fig. 5).
CAUTION
Set the cap white line at one of either the numerals
or drill marks.
2. Tlightening power adjustment
(1) Tightening power
Tightening power should correspond in its intensity
to the screw diameter. When too strong power is
used, the screw head may be broken or be injured.
Be sure to adjust the cap position according to the
screw diameter.
(2) Tightening power indication
Tightening power should be changed according to
the screw type and the materials to be tightened.
Guidance of the tightening power is indicated on
the outer frame of this unit with numerals "1", "2",
"3", "4" and "5". The minimum power is from "1"
position and bigger the value the stronger is the
power (see Fig. 5).
(3) How to adjusts the tightening power
Rotate the cap and set to one of the numerals.
Adjust the power by cap rotation in such a way that
when the power is too strong, set to the next
smaller numeral and set to the next larger numeral
when too weak.
CAUTION
The motor rotation may be locked to cease while
the unit is used as drill. While operating the driver
drill, take care not to lock the motor.
Too long hammering may cause the screw broken
due to excessive tightening.
3. Change rotation speed
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 "L", the drill rotates
at a high speed.
CAUTION
When changing the rotational speed with the shift
knob, confirm that the switch is off.
Changing the speed while the motor is rotating will
damage the gears.
