OPERATING INSTRUCTIONS
Installing or removing battery cartridge (Fig.1)
• To remove the battery cartridge, withdraw it from the
tool while pressing the buttons on both sides of the car-
tridge.
• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If not, it may accidentally fall out
of the tool, causing injury to you or someone around
you.
• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Checking the remaining battery capacity (Fig. 2)
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 battery has not been used for a long time, or is
needed refresh charging, the orange lamp begins to
flicker.
Use Makita refreshing adapter to refresh the battery.
CAUTION:
A battery cartridge extracted from the charger that has
been unplugged with the battery cartridge inserted does
not work even if it is inserted in the tool. At this time,
recharge it for about five seconds before use.
Installing or removing bit (Fig. 3)
CAUTION:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before installing or removing
the bit.
Use only the driver bit or socket bit shown in the figure
below.
Do not use any other driver bit or socket bit.
To install the bit, pull the sleeve in the direction of the
arrow and insert the bit into the sleeve as far as it will go.
Then release the sleeve to secure the bit.
To remove the bit, pull the sleeve in the direction of the
arrow and pull the bit out firmly.
NOTE:
If the bit is not inserted deep enough into the sleeve, the
sleeve will not return to its original position and the bit will
not be secured. In this case, try re-inserting the bit
according to the instructions above.

Switch action (Fig. 4)
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. 5)
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. 6)
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. 7)
2. Hit the tool housing around the grip once with a
screwdriver etc. (The indicating lamp will go out.)
(Fig. 8)
3. Release the trigger. (The indicating lamp will keep
lighting up lit for 0.5 seconds, then the lamp will go
out.) (Fig. 9)
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 preset 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 preset number is 12, hit the tool
housing two times.
7. Pull the trigger, then release the trigger. (The indicat-
ing lamp will light up.)
