Caution On Lithium-Ion Battery - Hitachi G 14DMR Handling Instructions Manual

English
– Ensure that mounted wheels and points are fitted
in accordance with the manufacturer's instructions;
– Ensure that blotters are used when they are provided
with the bonded abrasive product and when they
are required;
– Ensure that the abrasive product is correctly mounted
and tightened before use and run the tool at no-
load for 30 s in a safe position, stop immediately
if there is considerable vibration or if other defects
are detected. If this condition occurs, check the
machine to determine the cause;
– If a guard is equipped with the tool never use the
tool without such a guard;
– Do not use separate reducing bushings or adapters
to adapt large hole abrasive wheels;
– For tools intended to be fitted with threaded hole
wheel, ensure that the thread in the wheel is long
enough to accept the spindle length;
– Check that the work piece is properly supported;
– Do not use cutting off wheel for side grinding;
– Ensure that sparks resulting from use do not create
a hazard e.g. do not hit persons, or ignite flammable
substances;
– Ensure that ventilation openings are kept clear when
working in dusty conditions, if it should become
necessary to clear dust, first disconnect the tool
from the mains supply (use non metallic objects)
and avoid damaging internal parts;
– Always use eye and ear protection. Other personal
protective equipment such as dust mask, gloves,
helmet and apron should be worn;
– Pay attention to the wheel that continues to rotate
after the tool is switched off.
– Always charge the battery at a temperature of 0
– 40°C.
A temperature of less than 0°C will result in over
charging which is dangerous. The battery cannot
be charged at a temperature greater than 40°C.
The most suitable temperature for charging is that
of 20 – 25°C.
– Do not use the charger continuously.
When one charging is completed, leave the charger
for about 15 minutes before the next charging of
battery.
– 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 fire.
If the battery burnt, it may explode.
– Do not insert object into the air ventilation slots of
the charger.
Inserting metal objects or inflammables 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 and 2 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
battery voltage drops to about 12V (G18DL) /
about 8V (G14DL)), 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.
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.
