matically stops and the caution lamp starts blinking in red:
— The tool is overloaded by entangled weeds or other debris.

— The main power button is turned on while the
switch trigger is being pulled.
In this situation, release the switch trigger and remove
entangled weeds or debris if necessary. After that, pull
the switch trigger again to resume.
CAUTION:
If you need to remove the entangled
weeds on the tool or release the locked cutting tool,
be sure to turn the tool off before you start.
Overheat protection for tool or battery
If the tool or battery cartridge is overheated, the tool
stops automatically. When the tool or battery cartridge is
overheated, the speed indicator and ADT indicator go off

battery cool down before turning the tool on again.
Overdischarge protection
When the battery capacity becomes low, the tool stops
automatically. The speed indicator and ADT indicator go
