PRECAUTIONS FOR CORDLESS IMPACT DRIVER
DRILL
1. Always charge the battery at a temperature of 0 –
50°C. A temperature of less than 0°C will result in
over charging which is dangerous. The battery
cannot be charged at a temperature higher than
50°C.
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

Do not charge more than two batteries
consecutively.
3. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
