Arrow
The fastening torque can be adjusted in 17 levels by
turning the adjusting ring. Align the graduations with the
arrow on the tool body. You can get the minimum fas
-
tening 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 deter
-
mine which torque level is required for a particular
application.
ASSEMBLY
CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.

Tighten
Hold the ring and turn the sleeve counterclockwise to
open the chuck jaws. Place the driver bit/drill bit in the
chuck as far as it will go. Hold the ring firmly and turn
the sleeve clockwise to tighten the chuck.
To remove the driver bit/drill bit, hold the ring and turn
the sleeve counterclockwise.
OPERATION
CAUTION:
Always insert the battery cartridge
all the way until it locks in place.
If you can see the
red indicator on the upper side of the button, it is not
locked completely. Insert 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.
CAUTION:
When the speed comes down
extremely, reduce the load or stop the tool to
avoid the tool damage.
Hold the tool firmly with one hand on the grip and the
other hand on the bottom of the battery cartridge to
control the twisting action.

Screwdriving operation
CAUTION:
Adjust the adjusting ring to the
proper torque level for your work.
CAUTION:
Make sure that the driver bit is
inserted straight in the screw head, or the screw
and/or driver bit may be damaged.
Place the point of the driver bit in the screw head and
apply pressure to the tool. Start the tool slowly and then
increase the speed gradually. Release the switch trigger
as soon as the clutch cuts in.
NOTE:
When driving wood screw, pre-drill a pilot hole
2/3 the diameter of the screw. It makes driving easier
and prevents splitting of the workpiece.
Drilling operation
First, turn the adjusting ring so that the arrow points to
the
marking. Then proceed as follows.
Drilling in wood
When drilling in wood, the best results are obtained with wood
drills equipped with a guide screw. The guide screw makes
drilling easier by pulling the drill bit into the workpiece.
Drilling in metal
To prevent the drill bit from slipping when starting a
hole, make an indentation with a center-punch and
hammer at the point to be drilled. Place the point of the
drill bit in the indentation and start drilling.
Use a cutting lubricant when drilling metals. The excep
-
tions are iron and brass which should be drilled dry.
CAUTION:
Pressing excessively on the tool will
not speed up the drilling.
In fact, this excessive pressure
will only serve to damage the tip of your drill bit, decrease
the tool performance and shorten the service life of the tool.
CAUTION:
Hold the tool firmly and exert care
when the drill bit begins to break through the
workpiece.
There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION:
A stuck drill bit can be removed
simply by setting the reversing switch to reverse
rotation in order to back out. However, the tool
may back out abruptly if you do not hold it firmly.
CAUTION:
Always secure workpieces in a
vise or similar hold-down device.
CAUTION:
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.
MAINTENANCE
CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before attempting to perform inspection or
maintenance.
NOTICE:
Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
To maintain product SAFETY and RELIABILITY,
repairs, any other maintenance or adjustment should
be performed by Makita Authorized or Factory Service
Centers, always using Makita replacement parts.
