Tips for maintaining maximum
battery life
1. Charge the battery cartridge before completely dis-
charged. Always stop tool operation and charge the
battery cartridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room tempera-
ture at 10 °C - 40 °C (50 °F - 104 °F). Let a hot
battery cartridge cool down before charging it.

Low battery voltage:
The remaining battery capacity is too low and the tool will not
operate. If you turn the tool on, the motor runs again but stops
soon. In this situation, remove and recharge the battery.
