PRECAUTIONS ON USING CORDLESS CIRCULAR SAW

1. Always charge the battery at a temperature of 10 – 40°C.
A temperature of less than 10°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.
2. When one charging is completed, leave the charger for about
15 minutes before the next charging of 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-circuiting the
battery will cause a great electric current and overheat. It results
in burn or damage to the battery.

If the battery is burnt, it may explode.
7. When using this unit continuously, the unit may overheat, leading
to damage in the motor and switch. Please leave it without using it
for approximately 15 minutes.
8. Do not insert object into the air ventilation slots of the charger.
Inserting metal objects or infl ammables into the charger air
ventilation slots will result in electrical shock hazard or damaged
