(2) Regarding the temperature of the rechargeable battery.
The temperatures for rechargeable batteries are as
shown in Table 2, and batteries that have become hot
should be cooled for a while before being recharged.

(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 3.

NOTE
The charging time may vary according to temperature
and power source voltage.
4. Disconnect the charger's power cord from the
receptacle
5. Hold the charger fi rmly and pull out the battery
NOTE
After charging, pull out batteries from the charger fi rst,
and then keep the batteries properly.
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
○ When the battery charger has been continuously used,
the battery charger will be heated, thus constituting
the cause of the failures. Once the charging has been
completed, give 15 minutes rest until the next charging.
○ If the battery is recharged when it is warm due to battery
use or exposure to sunlight, the pilot lamp blinks.
The battery will not be recharged. In such a case, let the
battery cool before charging.
○ When the pilot lamp fl ickers (at 0.2-second intervals),
check for and take out any foreign objects in the charger's
battery installation hole. If there are no foreign objects, it
is probable that the battery or charger is malfunctioning.
Take it to Hitachi Authorized Service Centers.
PRIOR TO OPERATION
1. Setting up and checking the work environment
Check if the work environment is suitable by following the
precautions.
HOW TO USE
1. Confi rm the clutch dial position (See Fig. 4)
The three modes of screwdriver, drill and impact drill can
be switched by the position of the cap in this unit.
(1) When using this unit as a screwdriver, line up the one of
the numbers "1, 3, 5 ... 22" on the clutch dial, or the dots,
with the triangle mark on the outer body.
(2) When using this unit as a drill, align the clutch dial drill
mark "
" with the triangle mark on the outer body.
(3) When using this unit as an impact drill, align the cap
hammer mark "
" with the triangle mark on the outer
body.
CAUTION
○ The clutch dial cannot be set between the numerals "1, 3,
5 ... 22" or the dots.
○ Do not use with the clutch dial numeral between "22"
and the line at the middle of the drill mark. Doing so may
cause damage (See Fig. 5).
2. Tightening torque adjustment
(1) Tightening torque
Tightening torque should correspond in its intensity to
the screw diameter. When too strong torque is used,
the screw head may be broken or be injured. Be sure
to adjust the clutch dial position according to the screw
diameter.
