completely discharged.
Always stop tool operation and charge the
battery cartridge when you notice less tool
power.
2. Never recharge a fully charged
cartridge.
Overcharging shortens the battery service life.

temperature at 10 ﾟ C - 40 ﾟ C (50 ﾟ F - 104 ﾟ F).
Let a hot battery cartridge cool down before
charging it.
