ADDITIONAL SAFETY RULES FOR TOOL
1. Be aware that this tool is always in an operating
condition, because it does not have to be
plugged into an electrical outlet.
2. Hold tool by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring. Contact with a "live"
wire will also make exposed metal parts of the
tool "live" and shock the operator.
3. Wear ear protectors.
4. Check the socket carefully for wear, cracks or
damage before installation.
5. Hold the tool firmly.
6. Always be sure you have a firm footing.
7. Be sure no one is below when using the tool in
high locations.

1. Plug the battery charger into your power source. Two charging lights will flash in green color repeatedly.
2. Insert the battery cartridge into charger until it stops adjusting to the guide of charger. Terminal cover of charger
can be opened with inserting and closed with pulling out the battery cartridge.
3. When the battery cartridge is inserted, the charging light color will change from green to red and charging will
begin. The charging light will keep lighting up lit steadily during charging. One red charging light indicates charged
condition in 0 – 80% and two red ones indicates 80 – 100%.
4. With finish of charge, the charging lights will change from two red ones to two green ones.

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. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.

at 10°C – 40°C (50°F – 104°F).
3. Let a hot battery cartridge cool down by inserting it
into the charger.

NOTE:
• The battery charger is for charging Makita-battery car-
tridge. Never use it for other purposes or for other man-
ufacturer'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.
• If you charge a battery cartridge from a just-operated
tool or battery cartridge which has been left in a loca-
tion exposed to direct sunlight for a long time, the
charging light may flash in red color. If this occurs, wait
for a while. Charging will begin after the battery car-
tridge is cooled by the cooling fan installed in the
charger. When the temperature on battery is more than
approx. 70°C, two charging lights may flash in red color,
and when approx. 50°C – 70°C, one charging light in
red color.
• If the charging light flashes alternately in green and red
color, charging is not possible. The terminals on the
charger or battery cartridge are clogged with dust or
the battery cartridge is worn out or damaged.
