Reversing switch action (Fig. 6)
CAUTION:
• Always check the direction of rotation before opera-
tion.
• 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 revers-
ing switch lever to the neutral position.
This tool has a reversing switch to change the direc-
tion of rotation. Depress the reversing switch lever
from the A side for clockwise rotation or from the B
side for counterclockwise rotation. When the switch
lever is in the neutral position, the switch trigger
cannot be pulled.
Battery power warning lamp (Fig. 7)
The lamp lights up in red when the battery power
becomes low.
If you disregard the warning and continue operation,
the battery power will become not enough for the
normal performance of the tool, and soon the tool will
stop in order to avoid screwdriving with poor fastening
torque. And so, replace the battery by fully charged
one as soon as the red lamp lights up.
CAUTION:
The lamp may also light up in red before the battery
power becomes low under these conditions.
• Heavy load under which clutch mechanism does not
work. Do not use the tool in this condition.
(See the list of the capacity limit.)
Screwdriving operation (Fig. 8)
Place the point of the driver bit in the screw head and
apply pressure to the tool. Then switch the tool on.
When the clutch cuts in, the motor will stop automati-
cally. Then release the switch trigger.
NOTE:
Make sure that the driver bit is inserted straight in the
screw head, or the screw and/or bit may be damaged.
Limits of fastening capacity (Fig. 9, 10 & 11)
Use the tool within the limits of fastening capacity. If
you use the tool beyond the limits, the clutch does not
work. And the tool cannot deliver enough fastening
torque.
NOTE:
The revolution angle means the angle which a
screw/bolt revolves when the tool attains to 100%
from 50% of desired torque.

MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out any
work on the tool.
Replacement of carbon brushes (Fig. 12 & 13)
Replace carbon brushes when they are worn down to
the limit mark. Both identical carbon brushes should
be replaced at the same time.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by a
Makita Authorized Service Center.
