Makita DF347DWE [6/44] Assembly

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.

Installing or removing driver bit or drill bit

Fig.6

Turn the sleeve counterclockwise to open the chuck

jaws. Place the bit in the chuck as far as it will go. Turn

the sleeve clockwise to tighten the chuck.

To remove the bit, 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.

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.

• 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 Service Centers,

always using Makita replacement parts.
