18. Resting the unit after continuous work.
19. Do not touch the hammer case, as it gets very hot during
continuous work.
20. 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.
21. Do not use the charger continuously.
When one charging is completed, leave the charger for
about 15 minutes before the next charging of battery.
22. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
23. Never disassemble the rechargeable battery and
charger.
24. Never
short-circuit
Shortcircuiting the battery will cause a great electric
current and overheat. It results in burn or damage to the
battery.
25. Do not dispose of the battery in fi re. If the battery is burnt,
it may explode.
26. 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.
27. 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.
28. Make sure that the battery is installed fi rmly. If it is at all
loose it could come off and cause an accident.
29. Do not use the product if the tool or the battery terminals
(battery mount) are deformed.
Installing the battery could cause a short circuit that
could result in smoke emission or ignition.
30. Keep the tool's terminals (battery mount) free of swarf
and dust.
○ Prior to use, make sure that swarf and dust have not
collected in the area of the terminals.
○ During use, try to avoid swarf or dust on the tool from
falling on the battery.
○ When suspending operation or after use, do not leave
the tool in an area where it may be exposed to falling
swarf or dust.
Doing so could cause a short circuit that could result in
smoke emission or ignition.
31. Always use the tool and battery at temperatures between
-5°C and 40°C.
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 a 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.
the
rechargeable
battery.
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 for a purpose other than those
specifi ed.
5. If the battery charging fails to complete even when a
specifi ed recharging time has elapsed, immediately stop
further recharging.
6. Do not put or subject the battery to high temperatures or
high pressure such as into a microwave oven, dryer, or
high pressure container.
7. Keep away from fi re immediately when leakage or foul
odor are detected.
8. Do not use in a location where strong static electricity
generates.
9. 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.
10. 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.
WARNING
If a conductive foreign matter enters in the terminal of lithium
ion battery, the battery may be shorted, causing fi re. When
storing the lithium ion battery, obey surely the rules of
following contents.
○ Do not place conductive debris, nail and wires such as
iron wire and copper wire in the storage case.
○ To prevent shorting from occurring, load the battery in
the tool or insert securely the battery cover for storing
until the ventilator is not seen.
