FUNCTIONAL DESCRIPTION
NOTE: Depending on the conditions of use and the
ambient temperature, the indication may differ slightly
from the actual capacity.
Tool / battery protection system
CAUTION: Always be sure that the tool is
switched off and the battery cartridge is removed
before adjusting or checking function on the tool.
Installing or removing battery cartridge
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:
CAUTION: Always switch off the tool before
installing or removing of the battery cartridge.
Overload protection
CAUTION: Hold the tool and the battery car-
tridge firmly when installing or removing battery
cartridge. Failure to hold the tool and the battery
cartridge firmly may cause them to slip off your hands
and result in damage to the tool and battery cartridge
and a personal injury.
When the tool/battery is operated in a manner that causes
it to draw an abnormally high current, the tool automatically
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
To remove the battery cartridge, slide it from the tool
while sliding the button on the front of the cartridge.
When the tool/battery is overheated, the tool stops automati-
cally. Let the tool cool down before turning the tool on again.
Overdischarge protection
To install the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Insert it all the way until it locks in place
with a little click. If you can see the red indicator on the
upper side of the button, it is not locked completely.
When the battery capacity is not enough, the tool stops
automatically. In this case, remove the battery from the
tool and charge the battery.
Releasing protection lock
CAUTION: Always install the battery cartridge
fully until the red indicator cannot be seen. If not,
it may accidentally fall out of the tool, causing injury to
you or someone around you.
When the protection system works repeatedly, the tool is locked.
In this situation, the tool does not start even if turning the tool
off and on. To release the protection lock, remove the battery,
set it to the battery charger and wait until the charging finishes.
CAUTION: Do not install the battery cartridge
forcibly. If the cartridge does not slide in easily, it is
not being inserted correctly.
