Tool / battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off power to the
motor to extend tool and battery life. The tool will auto-
matically stop during operation if the tool or battery is
placed under one of the following conditions:
Overload protection
When the battery is operated in a manner that causes
it to draw an abnormally high current, the tool automati-
cally stops and the main power lamp blinks 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.
Overheat protection
When the tool or battery is overheated, the tool stops
automatically and the main power lamp lights up in red.
In this case, let the tool and battery cool before turning
the tool on again.
NOTE: In high temperature environment, the over-
heat protection likely to work and the tool stops
automatically.
Overdischarge protection
When the battery capacity is not enough, the tool stops
automatically and the main power lamp blinks in red. In
this case, remove the battery from the tool and charge
the battery.

You can use the tool in the Torque Boost mode for
cutting thick branches or hard branches. To use the tool
in the Torque Boost mode, when the tool is turned off,
press the main power switch for a few seconds until the
mode indicator lights up in green.

mode up to 60 seconds. Depending on the usage
conditions, this mode shifts to the normal mode in
less than 60 seconds.
NOTE: If the mode indicator blinks in green when
you press the main power switch for a few seconds,
the Torque Boost mode is not available. In this case,
follow the steps below.
• The Torque Boost mode is not available right
after the cutting operation. Wait for more than 10
seconds, and then press the main power switch
for a few seconds again.
• If you use the Torque Boost mode several times,
the use of the Torque Boost mode is restricted to
protect the battery. If the Torque Boost mode is
not available after waiting for more than 10 sec-
onds, replace the battery cartridge with a fully
charged one, or recharge the battery cartridge.
