instructions and cautionary markings on (1)
battery charger, (2) battery, and (3) product using
battery.
2. Do not disassemble battery cartridge.
3. If operating time has become excessively shorter,
stop operating immediately. It may result in a risk
of overheating, possible burns and even an
explosion.
4. If electrolyte gets into your eyes, rinse them out
with clear water and seek medical attention right
away. It may result in loss of your eyesight.

(1) Do not touch the terminals with any
conductive material.
(2) Avoid storing battery cartridge in a container
with other metal objects such as nails, coins,
etc.
(3) Do not expose battery cartridge to water or
rain.
A battery short can cause a large current flow,
overheating, possible burns and even a
breakdown.
6. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50°C (122°F).
7. Do not incinerate the battery cartridge even if it is
severely damaged or is completely worn out. The

Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the battery
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
temperature at 10°C - 40°C (50°F - 104°F). Let a hot
battery cartridge cool down before charging it.
4. Charge the battery cartridge once in every six
months if you do not use it for a long period of
time.

of the battery cartridge.
• To remove the battery cartridge, withdraw it from the
tool while pressing the buttons on both sides of the
cartridge.
• To install the battery cartridge, hold it so that the
battery cartridge front shape fits to that of the battery
installment opening and slip it into place. Always insert
it all the way until it locks in place with a little click. If
not, it may accidentally fall out of the tool, causing
injury to you or someone around you.
• Do not use force when installing the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Battery protection system
The tool is equipped with a battery protection system. This
system automatically cuts off power to the motor to extend
battery life.
The tool will automatically stop during operation if the tool
and/or battery are placed under one of the following
conditions:
• Overloaded:
The tool is operated in a manner that causes it to
draw an abnormally high current. In this situation,
release the trigger switch on the tool and stop the
application that caused the tool to become
overloaded. Then pull the trigger switch again to
restart.
• Low battery voltage:
The remaining battery capacity is too low and the tool
will not operate. If you pull the switch trigger, the
motor runs again but stops soon. In this situation,
remove and recharge the battery.
