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.

Screwdriving operation (Fig. 7)

CAUTION:

• Adjust the adjusting ring to the proper torque level for

your work.

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 screws, predrill pilot holes to make

driving easier and to prevent splitting of the workpiece.
See the chart.

Drilling operation

First, turn the adjusting ring so that the pointer 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 bit into the workpiece.

Drilling in metal

To prevent the 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 bit in the
indentation and start drilling. Use a cutting lubricant when
drilling metals. The exceptions 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 bit, decrease the tool
performance 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 similar

hold-down device.

• 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.

To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
