power. To check the remaining battery capacity,
slightly pull the switch trigger.
• When the LED display lights up but the tool does not
work even with a recharged battery cartridge, cool
down the tool fully. If the condition does not change,
have the tool repaired by a Makita local service center.
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 switch trigger. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop.
Lighting up the front lamp (Fig. 5)
CAUTION:
• Do not look in the light or see the source of light
directly.
Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
The lamp goes out 10 -15 seconds after releasing the
trigger.
NOTE:
• When the tool is overheated, the tool stops
automatically and the lamp starts flashing. In this case,
release the switch trigger. The lamp turns off in one
minute.
• Use a dry cloth to wipe the dirt off the lens of the lamp.
Be careful not to scratch the lens of lamp, or it may
lower the illumination.
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
counterclockwise rotation.
When the reversing switch lever is in the neutral position,
the switch trigger cannot be pulled.
Speed change (Fig. 7)
CAUTION:
• Always set the speed change lever fully to the correct
position. If you operate the tool with the speed change
lever positioned halfway between the “1” side and “2”
side, the tool may be damaged.
• Do not use the speed change lever while the tool is
running. The tool may be damaged.
• If the tool speed is coming down extremely during the
operation with “2”, slide the lever to the “1” and restart
the operation.

To change the speed, switch off the tool first. Select the
“2” side for high speed or “1” for low speed but high
torque. Be sure that the speed change lever is set to the
correct position before operation.
Adjusting the fastening torque (Fig. 8)
The fastening torque can be adjusted in 17 steps by
turning the adjusting ring. Align the graduations with the
arrow on the tool body. You can get the minimum
fastening torque at 1 and maximum torque at marking.
The clutch will slip at various torque levels when set at the
number 1 to 16. The clutch does not work at the
marking.
Before actual operation, drive a trial screw into your
material or a piece of duplicate material to determine
which torque level is required for a particular application.
The following shows the rough guide of the relationship
between the screw size and graduation.
