Caution On Lithium-Ion Battery - Hitachi DV 14DSL Handling Instructions Manual

English
5) Battery tool use and care
a) Recharge only with the charger specified by the
manufacturer.
A charger that is suitable for one type of battery
pack may create a risk of fire when used with
another battery pack.
b) Use power tools only with specifically designated
battery packs.
Use of any other battery packs may create a risk
of injury and fire.
c) When battery pack is not in use, keep it away
from other metal objects like paper clips, coins,
keys, nails, screws, or other small metal objects
that can make a connection from one terminal
to another.
Shorting the battery terminals together may
cause burns or a fire.
d) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause
irritation or burns.
6) Service
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool
is maintained.
PRECAUTION
Keep children and infirm persons away.
When not in use, tools should be stored out of reach of
children and infirm persons.
PRECAUTIONS FOR CORDLESS IMPACT DRIVER
DRILL
1. 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 higher than
40°C.
The most suitable temperature for charging is that
of 20 – 25°C.
2. When one charging is completed, leave the charger
for about 15 minutes before the next charging of
battery.
Do not charge more than two batteries
consecutively.
3. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
4. Never disassemble the rechargeable battery and
charger.
5. 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.
6. Do not dispose of the battery in fire.
If the battery is burnt, it may explode.
7. When drilling in wall, floor or ceiling, check for
buried electric power cord, etc.
8. 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.

9. Using an exhausted battery will damage the charger.
10. 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.
11. When mounting a bit into the keyless chuck, tighten
the sleeve adequately. If the sleeve is not tight, the
bit may slip or fall out, causing injury.
12. This product contains a strong permanent magnet
in the motor.
Observe the following precautions regarding
adhering of chips to the tool and the effect of the
permanent magnet on electronic devices.
CAUTION:
Do not place the tool on a workbench or work area
where metal chips are present.
The chips may adhere to the tool, resulting in injury
or malfunction.
If chips have adhered to the tool, do not touch it.
Remove the chips with a brush.
Failure to do so may result in injury.
If you use a pacemaker or other electronic medical
device, do not operate or approach the tool.
Operation of the electronic device may be affected.
Do not use the tool in the vicinity of precision
devices such as cell phones, magnetic cards or
electronic memory media.
Doing so may lead to misoperation, malfunction or
loss of data.

CAUTION ON LITHIUM-ION BATTERY

To extend the lifetime, the lithium-ion battery equips

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.
