IMPORTANT SAFETY INSTRUCTIONS
FOR BATTERY CHARGER
1. This manual contains important safety and operating instructions for battery charger
Model UC14YF2 or UC14YFA.
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 EB7, EB9, EB12,
EB14 series. 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.
10. Do not operate battery charger if it has received a sharp blow, been dropped, or otherwise
damaged in any way; take it to a qualified serviceman.
11. Do not disassemble battery charger; take it to a 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.
