Tips for maintaining maximum
battery life
1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the bat -
tery cartridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. 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 charging it.
4. Charge the battery cartridge if you do not use
it for a long period (more than six months).

DESCRIPTION
Installing or removing battery
cartridge
CAUTION:
• Always switch off the tool before installing or
removing the battery cartridge.
• Make sure that you lock the battery cover before
use. Otherwise, mud, dirt, or water may cause
damage to the product or the battery cartridge.
• 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.

• The tool does not work with only one battery
cartridge.

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 automatically stop during operation if the
tool or battery is placed under one of the following con -
ditions. 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
When the tool or battery is overheated, the tool stops
automatically without any indications. The tool does not
start even if turning on the tool. In this situation, let the
tool or battery cool before turning the tool on again.
NOTE: The battery overheat protection works only with
a battery cartridge with a star marking. The tool overheat
protection system works with any battery cartridges.
