Caution On Lithium-Ion Battery - Hitachi CR 18DSLP4 Instruction Manual

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 fire.
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).
Charging the battery at temperatures outside the
range of 32°F – 104°F (0°C – 40°C) may prevent
proper charging and reduce battery life.
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).
12. ALWAYS operate charger on standard household
electrical power (120 volts). Using the charger on
any other voltage may overheat and damage the
charger.
13. ALWAYS wait at least 15 minutes between charges
to avoid overheating the charger.
14. ALWAYS disconnect the power cord from its
receptacle when the charger is not in use.

CAUTION ON LITHIUM-ION BATTERY

To extend the lifetime, the lithium-ion battery equips
with the protection function to stop the output.
In the cases of 1 to 3 described below, when using this
product, even if you are pulling the switch, the motor
may stop. This is not the trouble but the result of
protection function.
1. When the battery power remaining runs out, the
motor stops.
In such case, charge it up immediately.
2. If the tool is overloaded, the motor may stop. In
this case, release the switch of tool and eliminate
causes of overloading. After that, you can use it
again.
3. If the battery is overheated under overload work,
the battery power may stop.
In this case, stop using the battery and let the
battery cool. After that, you can use it again.
(BSL1830)
Furthermore, please heed the following warning and
caution.
WARNING
In order to prevent any battery leakage, heat generation,
smoke emission, explosion and ignition beforehand,
please be sure to heed the following precautions.
1. Make sure that swarf and dust do not collect on
the battery.
During work make sure that swarf and dust do not
fall on the battery.
Make sure that any swarf and dust falling on the
power tool during work do not collect on the
battery.
Do not store an unused battery in a location
exposed to swarf and dust.
Before storing a battery, remove any swarf and
dust that may adhere to it and do not store it
together with metal parts (screws, nails, etc.).
2. Do not pierce battery with a sharp object such as a
nail, strike with a hammer, step on, throw or
subject the battery to severe physical shock.
3. Do not use an apparently damaged or deformed
battery.
4. Do not use the battery in reverse polarity.
5. Do not connect directly to an electrical outlets or
car cigarette lighter sockets.
6. Do not use the battery for a purpose other than
those specified.
7. If the battery charging fails to complete even when
a specified recharging time has elapsed,
immediately stop further recharging.
8. Do not put or subject the battery to high
temperatures or high pressure such as into a
microwave oven, dryer, or high pressure container.
9. Keep away from fire immediately when leakage
or foul odor are detected.
10. Do not use in a location where strong static
electricity generates.
11. If there is battery leakage, foul odor, heat
generated, discolored or deformed, or in any way
appears abnormal during use, recharging or
storage, immediately remove it from the
equipment or battery charger, and stop use.
CAUTION
1. If liquid leaking from the battery gets into your
eyes, do not rub your eyes and wash them well
with fresh clean water such as tap water and
contact a doctor immediately.
If left untreated, the liquid may cause eye-
problems.
2. If liquid leaks onto your skin or clothes, wash well
with clean water such as tap water immediately.
There is a possibility that this can cause skin
irritation.
3. If you find rust, foul odor, overheating, discolor,
deformation, and/or other irregularities when using
the battery for the first time, do not use and return
it to your supplier or vendor.
WARNING
If an electrically conductive foreign object enters the
terminals of the lithium ion battery, a short-circuit may
occur resulting in the risk of fire. Please observe the
following matters when storing the battery.
Do not place electrically conductive cuttings, nails,
steel wire, copper wire or other wire in the storage
case.
Either install the battery in the power tool or store
by securely pressing into the battery cover until
the ventilation holes are concealed to prevent
short-circuits (See Fig. 1).
