Overload protection

If the tool is overloaded by entangled branches or other
debris, and the middle indicators start blinking and
the tool automatically stops.
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
There are two types of overheating; tool overheating
and battery overheating. When the tool over heating
occurs, all speed indicators blink. When the battery over
heating occurs, indicator blinks.
If the overheating occurs, the tool stops automatically.
Let the tool and/or battery cool down before turning the
tool on again.
