CAUTION:
• Always switch off the tool before installing or
removing of the battery cartridge.
Hold the tool and the battery cartridge firmly
•
when installing or removing battery car-
tridge. 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.
To remove the battery cartridge, slide it from the tool
while sliding the button on the front of the cartridge.
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.
CAUTION:
• Always install the battery cartridge fully until the
red indicator cannot be seen. If not, it may acci-
dentally fall out of the tool, causing injury to you
or someone around you.
• Do not install the battery cartridge forcibly. If the
cartridge does not slide in easily, it is not being
inserted correctly.
Tool / battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off the power 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
This protection works when the tool is operated in a manner
that causes it to draw an abnormally high current. In this situ-
ation, turn the tool off and stop the application that caused the
tool to become overloaded. Then turn the tool on to restart.
Overheat protection
This protection works when the tool or battery is over-
heated. In this situation, let the tool and battery cool
before turning the tool on again.
Overdischarge protection
This protection works when the remaining battery
capacity gets low. In this situation, remove the battery
from the tool and charge the battery.
