Overload Protection; Overheat Protection; Overdischarge Protection; Main Power Switch - Makita ADCU10 Instruction Manual

Tool / battery protection system
The tool is equipped with a tool/battery protec-
tion system. This system automatically cuts off
power to the motor to extend tool and battery life.
The tool will automatically 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 automatically 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 bat-
tery cool before turning the tool on again.
NOTE: In high temperature environment, the
overheat 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.

Boost 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 main power lamp blinks in yellow
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.

more than 10 seconds, and then press the
main power switch again.
• If you use the Torque Boost mode several
times, the use of the Torque Boost mode
