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

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 tool is operated in a manner that causes it
to draw an abnormally high current, the tool automat-
ically stops and the main power lamp will blink. 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 is overheated, the tool automatically
stops and the capacity indicator lamp will blink as illus-
trated. In this situation, let the tool cool down before
turning the tool on again.
Overdischarge protection
When the battery capacity becomes low, the tool stops
automatically. If the product does not operate even
when the switches are operated, remove the batteries
from the tool and charge the batteries.
11 ENGLISH
Charge the battery cartridge with room tem-
perature at 10 °C - 40 °C (50 °F - 104 °F). Let
a hot battery cartridge cool down before
