Before removing the battery cartridge, lift the hook up
and loosen the lever for depth adjustment to lower the
tool base. Then slide the battery 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.
CAUTION:
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
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 automatically
stops. 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 stops automati-
cally, and the battery indicator blink about 60 seconds.
In this situation, let the tool cool down before turning the
tool on again.
On
Overload alert
If the tool is operated with excessive load, the mode
indicator will blink in green. The mode indicator stops
blinking and then lights up or turns off if you reduce the
load on the tool.

Overdischarge protection

when the switches are operated, remove the batteries
from the tool and charge the batteries.
