7. Do not charge continuously with the same charger.
- If the same charger is used to charge a number of tools continuously, it could overheat and be damaged.
Once charging is finished, leave the charger to cool for about 15 minutes before charging again.
8. Do not immediately recharge a battery that has been used up quickly.
- A storage battery that has been exhausted quickly due to continuous operation becomes abnormally hot.
Therefore, when such a battery is placed in the charger, a red pilot lamp comes on, either preventing a recharge,
or resulting in an insufficient charge. Always charge the battery after it has cooled down.
9. Do not charge for more than 2 hours.
- If the pilot lamp stays on even after charging for 2 hours, the charger may be faulty. Stop charging and consult
your nearest distributor.
10. Keep the battery-mounting socket clean.
- The battery-mounting socket on the charger has charging terminals. If this socket is contaminated with metal chips,
water or other foreign bodies, the terminals may be short-circuited, causing damage to the charger.
11. Do not attempt to disassemble either the storage battery or the charger.
- The charger and the storage battery houses condensers and electronic parts.
Disassembly could result in electric shock or damage to the charger; never try to disassemble them!
12. Never short-circuit the charger.
- The lithium-ion battery used with this unit has an extremely low internal resistance. If short-circuited, there may be
a surge in the current, resulting in overheating, burns or damage to the battery.
13. Never put the storage battery in a fire.
- Never put the battery in a fire or an incinerator or it may explode.
14. Keep the ventilation hole on the charger clean.
- Keep the ventilation hole on the charger clear of metal chips and inflammable materials as they may cause electric
shock or damage. Avoid using the charger in dusty places.
15. Stop charging if any abnormality is detected.
- If you detect excessive heat or any other abnormality while charging, stop immediately and have the charger repaired.
16. Store the charger and battery correctly.
- Store the charger and the storage battery in a dry place out of the reach of children and where the temperature
does not exceed 40
͠
. Never store under the eaves of a house, for example, where rain might get in.
Deterioration of the electrical insulation can result in electric shock.
17. Charge once every three months.
- It is recommended that even if you do not use them, lithium-ion batteries should be charged about once every three
months in order to prevent over-discharge.
18. Do not store fully-charged lithium-ion batteries for long periods of time.
- If you need to store the battery for a long period of time, store at room temperature at about 50% of the battery's capacity.
