charge, causing the battery low warning 
lamp to flash.

• If you notice the battery low warning 

lamp flashing, charge the battery pack 
immediately.

•  If it is started with too little battery power 

remaining, the tool may stop operating 
without the battery low warning lamp 
flashing first. This indicates that there is 
too little battery power remaining to use 
the tool, and the battery pack should be 
charged before further use.

• If the tool is subject to a sudden load 

during use that causes the motor to lock 
up, the over current prevention sensor 
may be triggered, and the impact power 
select display may flash. The lamp will 
stop flashing once you address the 
cause of the motor’s locking up and 
cycle the trigger.

Recommended Grip

Use the grip to hold and operate the driver 
with one hand. If the job requires additional 
force, you can push against the rear end of 
the driver with your other hand.

Li-ion Battery Pack

• For optimum battery life, store the Li-ion bat-

tery pack following use without charging it.

• When charging the battery pack, confirm 

that the terminals on the battery charger 
are free of foreign substances such as 
dust and water etc. Clean the terminals 
before charging the battery pack if any 
foreign substances are found on the ter-
minals. 

  The life of the battery pack terminals may 

be affected by foreign substances such as 
dust and water etc. during operation. 

• When battery pack is not in use, keep it 

away from other metal objects like: paper 
clips, coins, keys, nails, screws, or other 
small metal objects that can make a con-
nection from one terminal to another.

  Shorting the battery terminals together 

may cause sparks, burns or a fire.

• When operating the battery pack, make 

sure the work place is well ventilated.

• When the battery pack is removed from 

the main body of the tool, replace the bat-
tery pack cover immediately in order to

[Battery Charger]

Charging

Cautions

• If the temperature of the battery pack 

falls approximately below 

−

10°C (14°F), 

charging will automatically stop to prevent 
degradation of the battery.

• The ambient temperature range is 

between 0°C (32°F) and 40°C (104°F). 
If the battery pack is used when the battery 
temperature is below 0°C (32°F), the tool 
may fail to function properly. 

• Use the charger at temperatures between 

0°C and 40°C, and charge the battery at 
a temperature similar to that of the battery 
itself. (There should be no more than a 
15°C difference between the temperatures 
of the battery and the charging location.)

• When charging a cool battery pack (below 

0°C (32°F)) in a warm place, leave the 
battery pack at the place and wait for more 
than one hour to warm up the battery to 
the level of the ambient temperature.
