DOUBLE SPEED CHARGING ELECTRIC HAND DRILL
•matters needing attention
For machines with lithium-ion batteries, please use a dedicated charger and do not use chargers from other manufacturers to avoid danger caused by mismatches.
The lithium-ion battery has a function to prevent deep discharge. When the battery is low, the protection board will activate the over discharge protection function, and the machine will stop working. After prolonged use, the battery pack may become relatively hot. Wait for the battery pack to cool down before charging.
When the battery is first charged or stored for a long time, it will only receive 60% of its charge, and it needs to go through several charging and discharging cycles before it can be fully charged. New tool batteries only complete partial charging when leaving the factory, and must be charged for 1 hour before use.
