Caution On Lithium-Ion Battery - Hitachi NR 1890DC Manuel D'instructions

15. 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.
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
specifi ed.
SAFETY

7. If the battery charging fails to complete even when a
specifi ed 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 fi re 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.
12. Do not immerse the battery or allow any fl uids to fl ow
inside. Conductive liquid ingress, such as water,
can cause damage resulting in fi re or explosion.
Store your battery in a cool, dry place, away from
combustible and fl ammable items. Corrosive gas
atmospheres must be avoided.
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 fi nd rust, foul odor, overheating, discolor,
deformation, and/or other irregularities when using
the battery for the fi rst time, do not use and return it to
your supplier or vendor.
If an electrically conductive foreign object enters the
terminals of the lithium ion battery, a short-circuit may
occur resulting in the risk of fi re. 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.
