PRECAUTIONS FOR CORDLESS DRIVER DRILL

1. Always charge the battery at a temperature of 0 –
40°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 40°C.
The most suitable temperature for charging is that of
20 – 25°C.

battery.
Do not charge more than two batteries consecutively.
3. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
4. Never disassemble the rechargeable battery and
charger.
5. Never short-circuit the rechargeable battery. Short-

and overheat. It results in burn or damage to the
battery.
6. Do not dispose of the battery in fire.
If the battery is burnt, it may explode.
7. When drilling in wall, floor or ceiling, check for buried
electric power cord, etc.
