CAUTION:
•
Always insert the battery cartridge all the way
until it locks in place with a little click. If you can
see the red indicator on the upper side of the
button, it is not locked completely. Install it fully
until the red indicator cannot be seen. If not,
it may accidentally fall out of the tool, causing
injury to you or someone around you.
•
If the tool is operated continuously until the
battery cartridge has discharged, allow the tool
to rest for 15 minutes before proceeding with a
fresh battery.
Impact driver mode
CAUTION:
When changing the action mode to the
•
impact driver mode, always check that the
tool impacts by tightening wood screws. If
the action mode is not changed completely, the
tool twists the operator's hand resulting injury.
Screwdriving
Hold the tool firmly and place the point of the driver bit
in the screw head. Apply forward pressure to the tool to
the extent that the bit will not slip off the screw and turn
the tool on to start operation.
Tightening bolts
The proper fastening torque may differ depending upon
the kind or size of the screw/bolt, the material of the
workpiece to be fastened, etc. The relation between fas-
tening torque and fastening time is shown in the figures.

NOTE:
•
When the action mode is set to impact driver
mode, make sure that the tool impacts properly
by fastening a wood screw before operation.
If the tool does not work properly, contact your
nearest Makita service center.
•
Hold the tool pointed straight at the screw.
•
Use the proper bit for the head of the screw/bolt
that you wish to use.
•
When fastening screw M8 or smaller, carefully
adjust pressure on the switch trigger so that the
screw is not damaged.
•
If you tighten the screw for a time longer than
shown in the figures, the screw or the point of
the driver bit may be overstressed, stripped,
damaged, etc. Before starting your job, always
perform a test operation to determine the proper
fastening time for your screw.
The fastening torque is affected by a wide variety of
factors including the following. After fastening, always
check the torque with a torque wrench.
1.
When the battery cartridge is discharged almost
completely, voltage will drop and the fastening
torque will be reduced.
2.
Driver bit or socket bit
Failure to use the correct size driver bit or socket
bit will cause a reduction in the fastening torque.
3.
Bolt
•
Even though the torque coefficient and the
class of bolt are the same, the proper fasten-
ing torque will differ according to the diame-
ter of bolt.
•
Even though the diameters of bolts are the
same, the proper fastening torque will differ
according to the torque coefficient, the class
of bolt and the bolt length.
