Precautions For Battery And Charger; Caution On Lithium-Ion Battery - Hitachi CG36DL Handling Instructions Manual

English
16. If the tool is operating poorly and produces strange noise
or vibrations, turn off the motor immediately and ask your
dealer to have it inspected and repaired.
Continued use under these conditions could lead to
injury or tool damage.
17. If you drop or bump the tool, inspect it carefully to check
there is no damage, cracks or deformation.
Using a tool that is damaged, cracked or deformed could
result in injury.
18. Secure the tool during vehicle transport to ensure that it
lies still.
Failure to heed this warning may result in an accident.
19. This product contains a strong permanent magnet in the
motor.
Observe the following precautions regarding adhering of
chips to the tool and the eff ect 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 aff ected.
◯ 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
1. Do not turn on the nylon head for cutting objects other
than grass. Do not operate the tool in water puddles and
make sure that soil does not come into contact with the
nylon head.
2. The tool contains precision parts and should not be
dropped, exposed to strong impact or water.
The tool could be damaged or malfunction.
3. When the tool is to be stored after use or be transported,
remove the nylon head.
4. Do not expose the tool to insecticide and other
chemicals.
Such chemicals could cause cracking and other
damage.
5. Replace warning labels with new labels when they
become diffi cult to recognize or illegible and when they
start to peel.
Ask your dealer to provide the warning labels.
6. Do not touch the motor immediately after use since it
may be very hot.
PRECAUTIONS FOR BATTERY AND
CHARGER
1. Always charge the battery at a temperature of 0°C –
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°C – 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. 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.
5. Using an exhausted battery will damage the charger.
6. 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.
7. Never disassemble the rechargeable battery and
charger.
8. 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.
9. Do not dispose of the battery in fi re. If the battery is burnt,
it may explode.

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, recharging or storage, immediately remove it
from the equipment or battery charger, and stop use.
