Battery Protection System; Indicator Lamp - Makita UH353D Instruction Manual

NOTE: Depending on the conditions of use and the
ambient temperature, the indication may differ slightly
from the actual capacity.

Battery protection system

The tool is equipped with a battery protection system.
This system automatically cuts off power to the motor to
extend battery life.
The tool will automatically stop during operation if the
tool and/or battery are placed under one of the following
conditions:
Overloaded:
The tool is operated in a manner that causes it to draw
an abnormally high current.
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.
If the tool does not start, the battery is overheated. In
this situation, let the battery cool before turning the tool
on again.
Low battery voltage:
The remaining battery capacity is too low and the tool
will not operate. If you turn the tool on, the motor runs
again but stops soon. In this situation, remove and
recharge the battery.
Switch action
WARNING:
Before installing the battery car-
tridge into the tool, always check to see that the
switch trigger actuates properly and returns to
the "OFF" position when released.
WARNING:
For your safety, this tool is
equipped with the lock-off button which prevents
the tool from unintended starting. Never use the
tool if it starts when you pull the switch trigger
without pressing the lock-off button. Ask your local
Makita Service Center for repairs.
WARNING:
Never disable the lock function or
tape down the lock-off button.
NOTICE:
Do not pull the switch trigger forcibly
without pressing the lock-off button. The switch
may break.
