Installing the bit holder (Optional accessory)

(Fig. 11)

Fit the 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 bit holders.
Bits 45 mm long can be kept there.

OPERATION

CAUTION:

• Always insert the battery cartridge all the way until it

locks in place. If you can see the red part on the upper
side of the button, it is not locked completely. Insert it
fully until the red part cannot be seen. If not, it may
accidentally fall out of the tool, causing injury to you or
someone around you.

Hold the tool firmly with one hand on the grip and the
other hand on the bottom of the battery cartridge to con-
trol the twisting action.

CAUTION:

• Do not cover vents, or it may cause overheating and

damage to the tool.

Screwdriving operation (Fig. 13)

First, turn the action mode changing ring so that the
arrow on the tool body points to the marking. Adjust
the adjusting ring to the proper torque level for your work.
Then proceed as follows.
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.

CAUTION:

• Make sure that the driver bit is inserted straight in the

screw head, or the screw and/or bit may be damaged.

NOTE:

• When driving wood screw, predrill a pilot hole 2/3 the

diameter of the screw. It makes driving easier and pre-
vents splitting of the workpiece.

Drilling operation

First, turn the adjusting ring so that the pointer points to
the

marking. Then proceed as follows.

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 bit, decrease the tool perfor-
mance and shorten the service life of the tool.

• There is a tremendous force exerted on the tool/bit at

the time of hole break through. Hold the tool firmly and
exert care when the bit begins to break through the
workpiece.

• A stuck 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.

• Always secure small workpieces in a vise or with a sim-

ilar hold-down device.

• If the tool is operated continuously until the battery car-

tridge has discharged, allow the tool to rest for 15 min-
utes before proceeding with a fresh battery.

• Do not pull the switch trigger repeatedly when the

motor is locked. It may damage the tool.

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 bit into the
workpiece.

Drilling in metal

To prevent the bit from slipping when starting to make a
hole, make an indentation with a center-punch and ham-
mer at the point to be drilled. Place the point of the 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.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and the bat-

tery cartridge is removed before attempting to perform
inspection or maintenance.

• 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 per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
