CAUTION:
•The battery charger is for charging Makita battery cartridge. Never use it for other purposes or for other
manufacturer’s batteries.
•When you charge a new battery cartridge or a battery cartridge which has not been used for a long period of
time, it may not accept a full charge. This is a normal condition and does not indicate a problem. You can
recharge the battery cartridge fully after discharging it completely and recharging a couple of times.
•When you charge a battery cartridge from a just-operated machine or a battery cartridge which has been left
in a location exposed to direct sunlight or heat for a long time, let it cool off. Then re-insert it and try to charge
it once more.
•When you charge a new battery cartridge or a battery cartridge which has not been used for a long period,
sometimes the charging light will go out soon. If this occurs, remove the battery cartridge and re-insert it. If
the charging light goes out within one minute even after repeating this procedure a couple of times, the battery
cartridge is dead. Replace it with a new one.
Trickle charge (Maintenance charge)
If you leave the battery cartridge in the charger to prevent spontaneous discharging after full charge, the
charger will switch into its ‘‘trickle charge (maintenance charge)’’mode and keep the battery cartridge fresh and
fully charged.
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 Nickel Metal Hydride battery cartridge when you do not use it for more than six months.

The proper fastening torque may differ depending
upon the kind or size of the bolt. The relation between
fastening torque and fastening time is shown in the
figures.
Hold the tool firmly and place the socket over the bolt
or nut. Turn the tool on and fasten for the proper
fastening time.
NOTE:
•Hold the tool pointed straight at the bolt or nut
without applying excessive pressure on the tool.
•Excessive fastening torque may damage the bolt or
nut. Before starting your job, always perform a test
operation to verify the adequate fastening speed
and time for your bolt or nut.
The fastening torque is affected by a wide variety of
factors including the following.After fastening, always
check the torque with a torque wrench.
1. When the battery cartridge is discharged almost
completely, voltage will drop and the fastening
torque will be reduced.
2. Socket
•Failure to use the correct size socket will cause
a reduction in the fastening torque.
•A worn socket (wear on the hex end or square
end) will cause a reduction in the fastening
torque.
3. Bolt
•Even though the torque coefficient and the class
of bolt are the same, the proper fastening torque
will differ according to the diameter of the bolt.
•Even though the diameters of bolts are the
same, the proper fastening torque will differ
according to the torque coefficient, the class of
bolt and the bolt length.
4. Type of materials to be fastened, the manner of
holding the tool and the tool speed will affect the
torque.
CAUTION:
If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for 15
minutes before proceeding with a fresh battery.
Installing set plate (Optional accessory)
