or explosion.
3. If operating time has become excessively
shorter, stop operating immediately. It may
result in a risk of overheating, possible burns
and even an explosion.
4. If electrolyte gets into your eyes, rinse them

Do not expose battery cartridge to water
or rain.
A battery short can cause a large current
breakdown.
6. Do not store and use the tool and battery car-
tridge in locations where the temperature may
reach or exceed 50 °C (122 °F).
7. Do not incinerate the battery cartridge even if
it is severely damaged or is completely worn
8. Do not nail, cut, crush, throw, drop the battery
cartridge, or hit against a hard object to the
battery cartridge.
9. Do not use a damaged battery.
10. The contained lithium-ion batteries are subject
to the Dangerous Goods Legislation require-
ments.
-
-
11. When disposing the battery cartridge, remove
it from the tool and dispose of it in a safe
place. Follow your local regulations relating to
disposal of battery.
12. Use the batteries only with the products
-
13. If the tool is not used for a long period of time,
the battery must be removed from the tool.
14. During and after use, the battery cartridge may
take on heat which can cause burns or low
temperature burns. Pay attention to the han-
dling of hot battery cartridges.
15. Do not touch the terminal of the tool imme-
diately after use as it may get hot enough to
cause burns.
16. Do not allow chips, dust, or soil stuck into the
terminals, holes, and grooves of the battery
cartridge.
-
17. Unless the tool supports the use near
high-voltage electrical power lines, do not use

12 ENGLISH
Tips for maintaining maximum
battery life
1. Charge the battery cartridge before completely
discharged. Always stop tool operation and
charge the battery cartridge when you notice
less tool power.
2. Never recharge a fully charged battery car-
tridge. Overcharging shortens the battery
service life.
3. Charge the battery cartridge with room tem-
perature at 10 °C - 40 °C (50 °F - 104 °F). Let
a hot battery cartridge cool down before
charging it.
4. When not using the battery cartridge, remove
it from the tool or the charger.
5. Charge the battery cartridge if you do not use
it for a long period (more than six months).
