unplugged before carrying out any work on the tool.

Installing side grip (handle) (Fig. 3)

Installing or removing drill bit

For DA3010, DA3010F (Fig. 4)

To install the bit, place it in the chuck as far as it will go.

Tighten the chuck by hand. Place the chuck key in each

of the three holes and tighten clockwise. Be sure to

tighten all three chuck holes evenly.

To remove the bit, turn the chuck key counterclockwise in

just one hole, then loosen the chuck by hand.

For DA3011, DA3011F (Fig. 5)

Hold the ring and turn the sleeve counterclockwise to

open the chuck jaws. Place the 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 bit, hold the ring and turn the sleeve coun-

terclockwise.

OPERATION

Holding the tool (Fig. 6)

Hold the tool firmly with one hand on the gripping part of

the tool and the other hand on the side grip when per-

forming the tool.

Drilling operation

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 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 bit, decrease the tool perfor-

mance and shorten the service life of the tool.

• There is a tremendous twisting force exerted on the

tool/bit at the time of hole breakthrough. 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.

• Avoid drilling in material that you suspect contains hid-

den nails or other things that may cause the bit to bind

or break.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and

unplugged before attempting to perform inspection or

maintenance.

To maintain product SAFETY and RELIABILITY, repairs,

carbon brush inspection and replacement, any other

maintenance or adjustment should be performed by Mak-

ita Authorized or Factory Service Centers, always using

Makita replacement parts.
