PRECAUTIONS FOR BATTERY AND CHARGER
1. Always charge the battery at a temperature of 0 – 40°C.
Charging the battery at temperatures outside the range
of 0 – 40°C may prevent proper charging and reduce
battery life.
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.
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 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

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

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.
