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.
NOTE:
• The tool does not work with only one battery
cartridge.
Tool/ battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off power to the

When the tool 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.
