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
UC18YRL and UC18YFL.
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,
EB18, BCL14, BCL18 and EBM18 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.
Table 1
RECOMMENDED MINIMUM AWG SIZE FOR
EXTENSION CORDS FOR BATTERY CHARGERS
AC Input Rating Amperes* AWG Size of Cord
Equal to or but less Length of Cord, Feet (Meter)
greater than than 25 (7.5) 50 (15) 100 (30) 150 (45)
02 1818 18 16
23 1818 16 14
34 1818 16 14
* 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:
1,250 watts
125 volts
= 10 amperes
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.
