Installing or removing battery cartridge
Fig.1
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 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.
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
accidentally 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
system. This system automatically cuts off power to the
motor to extend tool and battery life.
The tool will automatically stop during operation if the
tool or battery are placed under one of the following
conditions. In some conditions, the indicators light up.
Overload protection
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.
Overheat protection for tool/ battery
When the tool/ battery is overheated, the tool stops
automatically without any indication. The tool does not
start even if pulling the switch trigger. In this situation,
let the tool/ battery cool before turning the tool on again.
NOTE:
The battery overheat protection works only with a
battery cartridge with a star marking.

Overdischarge protection

When the remaining battery capacity gets low, the
battery indicator blinks on the applicable battery side.
By further use, the tool stops and the battery indicator
lights up about 10 seconds. In this situation, charge the
battery cartridge.

CAUTION:
Always make sure that the handle is locked in the
•
