and the caution lamp starts blinking in green.
In this situation, turn the tool off and stop the application
that caused the tool to become overloaded. Then turn
the tool on to restart.
NOTICE:
Depending on the usage conditions,
the tool is automatically turned off without any
indication if the tool is overloaded by entangled
branches or debris. In this case, switch off the
tool and remove the battery cartridge, and then
remove entangled branches or debris using tools
such as pliers. After removing the branches or
debris, install the battery cartridge and turn on
the tool again.
Overheat protection for tool or
battery
If the tool or battery cartridge is overheated, the tool
stops automatically. When the tool is overheated, the
caution lamp lights up in red. When the battery cartridge
is overheated, the caution lamp blinks in red. Let the
tool and/or battery cool down before turning the tool on
again.

Overdischarge protection

When the battery capacity becomes low, the tool stops
automatically and the caution lamp starts blinking in red.
