Installing driver bit holder
Optional accessory
► Fig.12: 1. Driver bit holder 2. Driver bit
Fit the driver bit holder into the protrusion at the tool foot
on either right or left side and secure it with a screw.
When not using the driver bit, keep it in the driver bit
holders. Driver bits 45 mm-long (1-3/4") can be kept
there.
OPERATION
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 handle to control the twisting action.

NOTICE:
Do not cover vents, or it may cause over-
heating and damage to the tool.

Screwdriving operation

NOTICE:
Adjust the dial to the proper torque level
for your work.
NOTICE:
Make sure that the driver bit is inserted
straight in the screw head, or the screw and/or driver
bit may be damaged.
First, align marking with the arrow on the tool body
and adjust the torque level.
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 tool stops the rotation automatically and
the green light turns on for 5 seconds.
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.
NOTE: In a cold environment, the tool may stop at
lower torque level depending on circumstances.

Drilling operation

First, turn the action mode changing 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.
