WARNING
Improper use of the battery or battery charger can
lead to serious injury. To avoid these injuries:
1.
NEVER
disassemble the battery.
2.
NEVER
incinerate the battery, even if it is damaged
or is completely worn out. The battery can explode in
a
fi
re.
3.
NEVER
short-circuit the battery.
4.
NEVER
insert any objects into the battery charger’s
air vents. Electric shock or damage to the battery
charger may result.
5.
NEVER
charge outdoors. Keep the battery away
from direct sunlight and use only where there is low
humidity and good ventilation.
6.
NEVER
charge when the temperature is below 32°F
(0°C) or above 104°F (40°C).
7.
NEVER
connect two battery chargers together.
8.
NEVER
insert foreign objects into the hole for the
battery or the battery charger.
9.
NEVER
use a booster transformer when charging.
10.
NEVER
use an engine generator or DC power to
charge.
11.
NEVER
store the battery or battery charger in places
where the temperature may reach or exceed 104°F
(40°C) such as inside metal box or car.
12.
NEVER
expose the battery or battery charger to rain
or wet conditions.
13.
ALWAYS
operate charger on standard household
electrical power (120 volts). Using the charger on any
other voltage may overheat and damage the charger.
14.
ALWAYS
wait at least 15 minutes between charges to
avoid overheating the charger.

* 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
= 10 amperes
125 volts
8. Do not operate battery charger with damaged cord or
plug-replace them immediately.
9. Do not operate battery charger if it has received a
sharp blow, been dropped, or otherwise damaged in
any way; take it to a quali
fi
ed serviceman.
10. Do not disassemble battery charger; take it to a
quali
fi
ed serviceman when service or repair is
required. Incorrect reassembly may result in a risk of
electric shock or
fi
re.
11. To reduce risk of electric shock, unplug charger from
receptacle before attempting any maintenance or
cleaning. Removing the battery will not reduce this
risk.
IMPORTANT SAFETY INSTRUCTIONS
FOR USE OF THE BATTERY AND
BATTERY CHARGER
You must charge the battery before you can use the power
tool. Before using the model UC18YFSL battery charger,
be sure to read all instructions and cautionary statements
on it, the battery and in this manual.
REMEMBER: USE ONLY HITACHI BATTERY TYPES
BSL18 SERIES. OTHER TYPES OF BATTERIES MAY
BURST AND CAUSE INJURY!
Follow these instructions to avoid the risk of injury:
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 speci
fi
ed in Table 1.
