NOTE: Depending on the conditions of use and the
ambient temperature, the indication may differ slightly
from the actual capacity.
NOTE: The first (far left) indicator lamp will blink when
the battery protection system works.
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 automat-
ically stops without any indication. 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 lamp blinks. In this case, let the
tool and battery cool before turning the tool on again.
Overdischarge protection
When the battery capacity is not enough, the tool stops
automatically. In this case, remove the battery from the
tool and charge the battery.

tridge into the tool, always check to see that the
switch trigger actuates properly and returns to

CAUTION:
the tool is running. Failure to do so may result in
the loss of control of the tool and cause an injury.
NOTICE:
low speed for a long time, the motor will get over-
loaded, resulting in tool malfunction.
NOTICE:
only as far as 5 and back to 1. Do not force it past
5 or 1, or the speed adjusting function may no
longer work.
NOTE: Soft no-load rotation function
When the speed adjusting dial is set to "3" or higher,
the tool automatically reduces the speed at no-load to
reduce the vibration under no-load. Once operation
starts with a bit against concrete, blows per minute
increase and reach the numbers as shown in the
table. When temperature is low and there is less
fluidity in grease, the tool may not have this function
even with the motor rotating.
