IMPORTANT SAFETY INSTRUCTIONS
FOR BATTERY CHARGER

1. This manual contains important safety and operating instructions for battery charger

Model UC9SD, UC12SD and UC14SD.

2. Before using battery charger, read all instructions and cautionary markings on (1) battery

charger, (2) battery, and (3) product using battery.

3. To reduce risk of injury, charge HITACHI rechargeable battery type EB914 for UC9SD,

EB1214L for UC12SD and EB1414 for UC14SD. 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.

*

If the input rating of a battery charger is given in watts rather than in amperes, the
corresponding ampere rating is to be determined by dividing the wattage rating by the
voltage rating–for example:

9.

Do not operate battery charger with damaged cord or plug-replace them immediately.
