1. Be aware that this tool is always in an operat-
ing condition, because it does not have to be
plugged into an electrical outlet.
2. Wear ear protectors.
3. Check the socket carefully for wear, cracks or
damage before installation.
4. Hold the tool firmly.
5. Always be sure you have a firm footing. Be
sure no one is below when using the tool in
high locations.
6. The proper fastening torque may differ
depending upon the kind or size of the bolt.
Check the torque with a torque wrench.

‘‘live’’ electrical wires may be encountered, DO
NOT TOUCH ANY METAL PARTS OF THE

OPERATING INSTRUCTIONS
Installing or removing battery cartridge
(Fig. 1)
• Always switch off the tool before insertion or
removal of the battery cartridge.
• To remove the battery cartridge, pull out the set
plate on the tool and grasp both sides of the
cartridge while withdrawing it from the tool.
• To insert the battery cartridge, align the tongue on
the battery cartridge with the groove in the housing
and slip it into place. Snap the set plate back into
place. Be sure to close the set plate fully before
using the tool.
• Do not use force when inserting the battery car-
tridge. If the cartridge does not slide in easily, it is
not being inserted correctly.
Charging (Fig. 2)
1. Plug the battery charger into your power source.
2. Insert the battery cartridge so that the plus and
minus terminals on the battery cartridge are on the
same sides as their respective markings on the
battery charger. Insert the cartridge fully into the
port so that it rests on the charger port floor.
3. When the battery cartridge is inserted, the charg-
ing light color will flash in red color and charging
will begin.
4. When charging is completed, the charging light
goes out. The charging time is as follows:
Battery 7000, 7100, 7120, 9000, 9100, 9100A,
9120: approx. 60 minutes.
5. If you leave the battery cartridge in the charger
after the charging cycle is complete, the charger
will switch into its ‘‘trickle charge (maintenance
charge)’’ mode.
6. After charging, remove the battery cartridge from
the charger and unplug the charger from the
power source.

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 tool 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 (main-
tenance charge)’’ mode and keep the battery car-
tridge 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 tempera-
ture at 10°C – 40°C (50°F – 104°F).
Let a hot battery cartridge cool down before
charging it.
Installing or removing the bit (Fig. 3)
Important:
Always be sure that the tool is switched off and the
battery cartridge is removed before installing or
removing the bit.
For tool without sleeve to retain the bit
Use insert bits shown in figure. To install the bit, just
insert it into the spindle.
