The tool is intended for drilling in wood, metal and plastic. ENF002-2 Power supply

The tool should be connected only to a power supply of

the same voltage as indicated on the nameplate, and can

only be operated on single-phase AC supply. They are

double-insulated and can, therefore, also be used from

sockets without earth wire.

SAFETY WARNINGS GEA010-2 General Power Tool Safety Warnings

WARNING Read all safety warnings, instructions,

illustrations and specifications provided with this

power tool. Failure to follow all instructions listed below

may result in electric shock, fire and/or serious injury.

The term “power tool” in the warnings refers to your

mains-operated (corded) power tool or battery-operated

(cordless) power tool. GEB172-1

DRILL SAFETY WARNINGS Safety instructions for all operations

1. Use the auxiliary handle(s). Loss of control can

cause personal injury.

2. Brace the tool properly before use. This tool pro-

duces a high output torque and without properly

bracing the tool during operation, loss of control may

occur resulting in personal injury.

3. Hold the power tool by insulated gripping sur-

faces, when performing an operation where the

cutting accessory may contact hidden wiring or

its own cord. Cutting accessory contacting a “live”

wire may make exposed metal parts of the power

tool “live” and could give the operator an electric

4. Always be sure you have a firm footing. Be sure

no one is below when using the tool in high loca-

5. Hold the tool firmly.

6. Keep hands away from rotating parts.

7. Do not leave the tool running. Operate the tool

only when hand-held.

8. Do not touch the drill bit or the workpiece imme-

diately after operation; they may be extremely

hot and could burn your skin.

9. Some material contains chemicals which may be

toxic. Take caution to prevent dust inhalation

and skin contact. Follow material supplier safety

10. If the drill bit cannot be loosened even you open

the jaws, use pliers to pull it out. In such a case,

pulling out the drill bit by hand may result in injury by

Safety instructions when using long drill bits

1. Never operate at higher speed than the maxi-

mum speed rating of the drill bit. At higher

speeds, the bit is likely to bend if allowed to rotate

freely without contacting the workpiece, resulting in

2. Always start drilling at low speed and with the bit

tip in contact with the workpiece. At higher

speeds, the bit is likely to bend if allowed to rotate

freely without contacting the workpiece, resulting in

3. Apply pressure only in direct line with the bit

and do not apply excessive pressure. Bits can

bend causing breakage or loss of control, resulting

FUNCTIONAL DESCRIPTION CAUTION:

• Always be sure that the tool is switched off and

unplugged before adjusting or checking function on the

Switch action (Fig. 1)

• Before plugging in the tool, always check to see that

the switch trigger actuates properly and returns to the

“OFF” position when released.

To start the tool, simply pull the switch trigger. Release

the switch trigger to stop.

Reversing switch action (Fig. 2)

This tool has a reversing switch to change the direction

of rotation. Depress the reversing switch lever from the A

side for clockwise rotation or from the B side for counter-

• Always check the rotational direction before operation.

• Use the reversing switch only after the tool comes to a

complete stop. It will damage the tool to change the

rotational direction before the tool stops.

Speed change (Fig. 3)

Two speed ranges can be preselected with the speed

To change the speed, depress the lock button and turn

the speed change knob so that the pointer points to the

position 1 for low speed or the position 2 for high speed.

• Use the speed change knob only after the tool comes

to a complete stop. Changing the tool speed before the

tool stops may damage the tool.

• Always set the speed change knob carefully into the

correct position. If you operate the tool with the speed

change knob positioned halfway between the position 1

and the position 2, the tool may be damaged.

The torque limiter will actuate when a certain torque level

is reached (for low speed setting: position 1). The motor

will disengage from the output shaft. When this happens,

the bit will stop turning.

Switch handle mounting positions (Fig. 4)

The switch handle can be rotated to either 90° left or right

to fit your work needs. First, unplug the tool. Press the

lock button and rotate the switch handle until the  mark

on the lock button is aligned with that on the motor hous-

ing. The switch handle will be locked in that position.

• Always be sure that the tool is switched off and

unplugged before carrying out any work on the tool.

Installing side grip (auxiliary handle) (Fig. 5)

• Always be sure that the side grip is installed securely

Screw the side grip on the tool securely. The side grip

can be installed on either side of the tool, whichever is

Spade grip (Fig. 6 & 7)

The spade grip can be installed in any position as shown

in the figure. To change the position, loosen the hex bolts

(both sides) with a hex wrench and turn the spade grip to

the desired position. Then tighten the hex bolts securely.

After reposition the grip, return the hex wrench to the

• Do not fix the spade grip beyond the limits of the arrow.

Be cautious that your hand is not caught in the grip.

Keep the hand away from the drill chuck. They can

lead to serious accidents.

• Always be sure that the hex bolts (both sides) of the

spade grip are tightened securely.

Installing or removing drill bit (Fig. 8)

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.

After using the chuck key, be sure to return it to the origi-

OPERATION Holding tool (Fig. 9 & 10)

• This is a powerful tool. High torque is developed and it

is important that the tool is securely held and properly

Grasp the switch handle with one hand and the spade

grip with the other hand. When drilling a large hole with a

self-feed bit, etc., the side grip (auxiliary handle) should

be used as a brace to maintain safe control of the tool.

When drilling action is forward (clockwise), the tool

should be braced to prevent a counterclockwise reaction

if the bit should bind. When reversing, brace the tool to

prevent a clockwise reaction. If the bit must be removed

from a partially drilled hole, be sure the tool is properly

braced before reversing.6

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

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.

• 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

• Always secure small workpieces in a vise or similar

• Avoid drilling in material that you suspect contains hid-

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

MAINTENANCE CAUTION:

• Always be sure that the tool is switched off and

unplugged before attempting to perform inspection or

Replacing carbon brushes (Fig. 11 & 12)

Remove and check the carbon brushes regularly.

Replace when they wear down to the limit mark. Keep

the carbon brushes clean and free to slip in the holders.

Both carbon brushes should be replaced at the same

time. Use only identical carbon brushes.

Use a screwdriver to remove the brush holder caps. Take

out the worn carbon brushes, insert the new ones and

secure the brush holder caps.

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.
