Makita BTW072 Manuel D'instructions page 6

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.
• Any of the following conditions indicates damage to the
charger and/or battery cartridge. Ask your Makita
Authorized or Factory Service Center to check them.
1) The charging light does not flash (green) when the
battery charger is plugged into a power source.
2) The charging light does not light up or flash (red)
when the battery is inserted in the charger port.
3) Charging is not completed at even more than two
hours after red light comes ON at start of charging.
Refresh charging
• Refreshing adapter (optional accessory) can refresh an
inactive battery cartridge.
• Refresh charging should be done once a week.
• When you charge a new battery cartridge or a battery
cartridge that has not been used for a long time, it may
not accept a full charge. In this case, refresh charging
must be done. The battery cartridge may decrease the
tool performance, because the chemical substance of
the battery cartridge is inactive.
Checking the remaining battery capacity (Fig. 3)
When charging
When the charging begins, the first (far left) indicator
lamp begins to flicker. Then, as charging proceeds, the
other lamps light, one after the other, to indicate the bat-
tery capacity.
When using
When the tool is switched on, the lamps will light to indi-
cate the remaining battery capacity. When the tool is
switched off, the light goes out automatically. If the bat-
tery has not been used for a long time, or is needed
refresh charging, the (C) lamp begins to flicker. Use Mak-
ita refreshing adapter to refresh the battery.
Installing or removing socket (Fig. 4)
CAUTION:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before installing or removing
the socket.
To install the socket, push it onto the anvil of the tool until
it locks into place. To remove the socket, simply pull it off.

Switch action (Fig. 5)
CAUTION:
Before inserting the battery cartridge into the tool, always
check to see that the switch trigger actuates properly and
returns to the "OFF" position when released.
To start the tool, simply pull the trigger. Tool speed is
increased by increasing pressure on the trigger. Release
the trigger to stop.
Reversing switch action (Fig. 6)
CAUTION:
• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
• When not operating the tool, always set the reversing
switch lever to the neutral position.
This tool has a reversing switch to change the direction of
rotation. Depress the reversing switch lever from the A
side for clockwise rotation or from the B side for counter-
clockwise rotation. When the reversing switch lever is in
the neutral position, the switch trigger cannot be pulled.
Auto-stop mechanism (Fig. 7)
The tool stops automatically after the battery capacity
reaches under 20% to prevent the lack of fastening
torque. (Red color lamp lights on.) Charge the battery or
use a new fully charged one.
Auto-stop setting for number of impacts
This tool has a convenient auto-stop mechanism that
allows you to preset the desired number of impacts in
terms of the application. The tool then stops automati-
cally after reaching the preset number of impacts.
1. Pulling the trigger, insert the battery cartridge. Keep
on pulling the trigger after inserting the battery car-
tridge. (The indicating lamp on the back of the tool
will flash about 10 times, then the lamp will keep
lighting up lit.) (Fig. 8)
2. Hit the tool housing around the grip once with a
screwdriver etc. (The indicating lamp will go out.)
(Fig. 9)
3. Release the trigger. (The indicating lamp will keep
lighting up lit for 0.5 seconds, then the lamp will go
out.) (Fig. 10)
4. Hit the tool housing preset number of first digit
except 0. (The indicating lamp will light up in green
color. Then, the light goes out. )
Example: When the presetting number is 12, hit the
tool housing once.
5. Pull the trigger, then release it.
6. Hit the tool housing preset number of second digit
except 0. (The indicating lamp will light up in red
color. Then, the light goes out.)
Example: When the presetting number is 12, hit the
tool housing two times.
7. Pull the trigger, then release the trigger. (The indicat-
ing lamp will light up.)
8. Remove the battery cartridge. (Presetting has fin-
ished.) (The indicating lamp will go out.)
CAUTION:
When you change the presetting, do the same procedure
as above 1 – 8.
