Caution On Lithium-Ion Battery; Specifications - Hitachi Koki GP 10DL Handling Instructions Manual

When one charging is completed, leave the charger for
about 15 minutes before the next charging of battery.
Do not charge the battery more than 2 hours.
– Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
– Never disassemble the rechargeable battery and
charger.
– Never short-circuit the rechargeable battery.
Short-circuiting the battery will cause a great electric
current and overheat. It results in burn or damage to
the battery.
– Do not dispose of the battery in fi re.
If the battery burnt, it may explode.
– When drilling in wall, fl oor or ceiling, check for buried
electric power cord, etc.
– Do not insert object into the air ventilation slots of the
charger.
Inserting metal objects or infl ammables into the
charger air ventilation slots will result in electrical
shock hazard or damaged charger.
– Bring the battery to the shop from which it was
purchased as soon as the post-charging battery life
becomes too short for practical use. Do not dispose of
the exhausted battery.
– Using an exhausted battery will damage the charger.

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.
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,
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 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.
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 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 (See Fig. 3).
