⅜ Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with UC14YFA is taken out, wait for a minimum of
3 seconds before reinserting it to continue charging.
If the battery is reinserted within 3 seconds, the
battery may not be properly charged.

Before using the driver drill, charge the battery as follows.
1. Connect the charger power cord to the receptacle
Connecting the power cord will turn on the charger.
2. Insert the battery into the charger
Insert the battery firmly while observing its direction,
until it contacts the bottom of the charger (the pilot
lamp lights up) (See Fig. 4).
CAUTION
If the pilot lamp does not light up, pull out the
power cord from the receptacle and check the
battery mounting condition.
(1) Regarding the temperatures of the rechargeable
battery
The temperatures for rechargeable batteries are as
shown in Table 4.
Table 4 Recharging ranges of batteries
(2) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 5.
Table 5 Charging time (At 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 120 minutes have elapsed after starting 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 up. At that time, cool the battery first,
then start charging.
3. Disconnect the charger’s power cord from the
receptacle
4. Hold the charger firmly and pull out the battery
NOTE
After charging, pull out batteries from the charger
first, and then keep the batteries properly.
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.
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. Confirm the clutch dial position (See Fig. 5)
The tightening torque of this unit can be adjusted
according to the clutch dial position, at which the
clutch dial is set.
(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.
CAUTION
⅜ The clutch dial cannot be set between the numerals
“1, 3, 5 ... 22” or the dots.
⅜ 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. 6).
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.
(2) Tightening torque indication
The tightening torque differs depending on the type
of screw and the material being tightened.
The unit indicates the tightening torque with the
numbers “1, 3, 5 ... 22” on the clutch dial, and a
dots. The tightening toque at position “1” is the
weakest and the torque is strongest at the highest
number (See Fig. 5).
