IMPORTANT SAFETY
INSTRUCTIONS FOR BATTERY
CHARGER
WARNING
Death or serious bodily injury could result from
improper or unsafe use of battery chargers.
To avoid these risks, follow these basic safety
instructions:
READ ALL INSTRUCTIONS
1. This manual contains important safety and
operating instructions for battery charger Model
UC7SD.
2. Before using battery charger, read all instructions
and cautionary markings on (1) battery charger,

3. To reduce risk of injury, charge HITACHI
rechargeable battery type EB714S. Other type of
batteries may burst causing personal injury and
damage.
4. Do not expose battery charger to rain or snow.
5. Use of an attachment not recommended or sold
by the battery charger manufacturer may result
in a risk of fire, electric shock, or injury to persons.
6. To reduce risk of damage to electric plug and cord,
pull by plug when disconnecting battery charger.
7. Make sure cord is located so that it will not be
stepped on, tripped over, or otherwise subjected
to damage or stress.
8. An extension cord should not be used unless
absolutely necessary. Use of improper extension
cord could result in a risk of fire and electric shock.
If extension cord must be used make sure:
a. That blades of extension cord are the same number,
size, and shape as those of plug on battery charger;
b. That extension cord is properly wired and in good
electrical condition; and
c. That wire size is large enough for AC ampere rating
of battery charger as specified in Table 1.

qualified serviceman when service or repair is
required. Incorrect reassembly may result in a risk
of electric shock or fire.
12. To reduce risk of electric shock, unplug charger
from receptacle before attempting any
maintenance or cleaning. Removing the battery will
not reduce this risk.
13. This battery charger might be attached to HITACHI
battery operated tools as a standard accessory. In
this case, please confirm Instruction Manual of the
HITACHI battery operated tools before using the
battery charger.

1. Insert the battery into the battery charger. Make sure it
contacts the bottom of the battery charger.
2. Insert the plug of battery charger into the receptacle.
3. Charging
䡬 When the plug of battery charger has been inserted
into the receptacle, charging will commence and the
pilot lamp will light on.
NOTE: If the pilot lamp does not light, pull out the plug
from the receptacle and check if the battery is
properly mounted.
䡬 In approx. 60 min. at 70°F (20°C), when the battery is
fully charged, the pilot lamp will go out.
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 battery charger from the receptacle.
CAUTION
Do not pull the plug out of the receptacle by
pulling on the cord.
Make sure to grasp the plug when removing from
receptacle to avoid damaging cord.
5. Remove the battery from the battery charger.
Supporting the battery charger with hand, pull out the
battery from the battery charger.
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.
䡬 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.
䡬 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
䢇 When the battery charger has been continuosly
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.
䢇 If the battery is recharged when it is warm due to
battery use or exposure to sunlight, the pilot lamp
may not light.
The battery will not be recharged. In such a case,
let the battery cool before charging.
䢇 If the battery charger does not work while the
battery is mounted correctly, it is probable that
the battery or charger is malfunctioning. Take it to
your authorized Service Center.
BEFORE OPERATION
Read section titled “SAFETY” (pages 4 – 9).
Make sure of the followings before operation.
WORKING ENVIRONMENT
WARNING
䢇 No flammable gas, liquid
or other flammable
objects at worksite.
䢇 Use outside or well–
ventilated areas.
Do not inhale.
䢇 Keep the Nailer, fuel cell
and battery away from
120°F MAX
(50°C)
sunshine and from
temperature exceeding
120°F (50°C).
䢇 Keep away from ignition
sources. No smoking.
䢇 Clear the area of children
or unauthorized
personnel.
COLD WEATHER CARE
䡬 Do not store the Nailer, fuel cell and battery in a cold
weather environment. Keep the Nailer, fuel cell and
battery in a warm area until beginning the work.
䡬 If the Nailer, fuel cell and battery are already cold,
bring it in a warm area and allow the Nailer to warm
up before use. Observe temperature limit of max. 120°F
(50°C).
Do not expose to an open flame and sparks!
CAUTION
䢇 This Nailer may not drive completely below when;
at low temperature fuel cell loose the required
propellant force, at high temperature fuel cell
overdose.
䢇 Do not use the Nailer in the rain or where
excessive moisture is present.
䢇 This Nailer is not recommended for use at
altitudes above 5,000 feet (1,500 m), or in
temperature below 30°F (0°C).

PREPARING THE FUEL CELL
Read section titled “SAFTY, IMPORTANT SAFETY
INSTRUCTIONS FOR FUEL CELL (page 7).
DANGER
䢇 The fuel cell is
flammable.
䢇 Keep away from ignition
sources.
䢇 Do not spray to a naked
flame or any
incandescent material.
䢇 Do not smoke when
handling fuel cell.
䢇 Keep stem of fuel cell
away from face or skin.
Expanding gases cause
low temperatures. Do
not contact with gases.
䢇 Do not inhale.
䢇 Keep out of reach of
children.
Check the metering valve:
Press the metering valve stem on fuel cell two or three
times against a stationary object and release.
If gas is not dispersed, fuel cell is empty. Replace it.
Observe Safety Regulations.
The fuel cell is now ready to insert into the Nailer.
PREPARING THE BATTERY
Read section titled “SAFETY, IMPORTANT SAFETY
INSTRUCTIONS FOR BATTERY CHARGER” (page 8).
You must charge the battery before use.
The charging method of battery is shown in page 12 - 14.
TESTING THE NAILER
DANGER
䢇 Operators and others in
work area MUST wear
safety glapsses with side
shields which conforms
to ANSI Z87.1
specifications.
CAUTION
䢇 If the gas leaks from the metering valve or the gas
cartridge after attached the metering valve,
replace with the new metering valve.
䢇 Do not attempt to reuse the metering valve.
Replace with the new metering valve.
To attach the metering valve to a fuel cell:
(1) Separate the metering valve and the
cap from the gas cartridge.
(2) Press forward (stem side) and
downward on the front side of the
metering valve.
WARNING
䢇 Never use Nailer unless push lever is operating
properly.
The machine employs a preventive mechanism for
unloaded operation.
The machine enters a state where the push lever cannot be
pushed up. This takes place when the magazine is not
loaded with nails or when the remaining number of nails
becomes less than 8 or 9.
CAUTION
䢇 Use caution not to throw the push lever tip onto
wood.
Before actually beginning the nailing work, test the Nailer
by using the checklist below. Conduct the tests in the
following order.
If abnormal operation occurs, stop using the Nailer and
contact a Hitachi authorized service center immediately.
(1) REMOVE ALL NAILS, FUEL CELL AND BATTERY FROM
NAILER.
䡺 ALL SCREWS MUST BE TIGHTENED.
(3) Press downward on the rear of the
metering valve until it seals.
