SPECIFIC SAFETY RULES

• Always use safety chain. Mounting can release.

• DANGER! To reduce the risk of injury, always keep

hands, gloves, rags, clothing, etc. away from mov-

ing parts and chips. Do not try to remove chips while

the cutter is rotating. Chips are sharp and can pull

objects into moving parts.

• Clean the surface before attaching the drill

stand to the work surface. Paint, rust, scale, or

uneven surfaces decrease the holding strength of

the magnet. Chips, burrs, dirt and other foreign

matter on the surface of the magnet base will also

decrease holding power.

• Do not attach magnetic base to nonmagnetic

grades of stainless steel. The magnet base WILL

NOT hold. The 4272-21 drill attaches magnetically

to 3/8" or thicker ferrous stock, and the 4274-21 to

1/4" or thicker ferrous stock. Do not use on stock

less than 1/4".

• Hold power tool by insulated gripping surfaces,

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 shock.

• Safety Strap

• Do not use near acids or bleaching agents.

• Do not use for overhead lifting.

• Do not use strap if webbing is cut.

• Webbing must be protected from sharp edges.

• All hardware must be in line with direction of

pull for rated capacity.

• Maintain labels and nameplates. These carry

important information. If unreadable or missing,

contact a MILWAUKEE service facility for a free

replacement.

• WARNING Some dust created by power sanding,

sawing, grinding, drilling, and other construction

activities contains chemicals known to cause can-

cer, birth defects or other reproductive harm. Some

examples of these chemicals are:

• lead from lead-based paint

• crystalline silica from bricks and cement and other

masonry products, and

• arsenic and chromium from chemically-treated

lumber.

* Requires use of 1/2" drill chuck adapter, see "Accessories."

PERSONAL SAFETY

GENERAL POWER TOOL SAFETY WARNINGS

WORK AREA SAFETY

ELECTRICAL SAFETY

POWER TOOL USE AND CARE

SERVICE

• Keep work area clean and well lit. Cluttered or

dark areas invite accidents.

• Do not operate power tools in explosive atmos-

pheres, such as in the presence of ﬂ ammable

liquids, gases or dust. Power tools create sparks

which may ignite the dust or fumes.

• Keep children and bystanders away while op-

erating a power tool. Distractions can cause you

to lose control.

• Power tool plugs must match the outlet. Never

modify the plug in any way. Do not use any

adapter plugs with earthed (grounded) power

tools. Unmodiﬁ ed plugs and matching outlets will

reduce risk of electric shock.

• Avoid body contact with earthed or grounded

surfaces, such as pipes, radiators, ranges and

refrigerators. There is an increased risk of electric

shock if your body is earthed or grounded.

• Do not expose power tools to rain or wet condi-

tions. Water entering a power tool will increase the

risk of electric shock.

• Do not abuse the cord. Never use the cord for

carrying, pulling or unplugging the power tool.

Keep cord away from heat, oil, sharp edges

or moving parts. Damaged or entangled cords

increase the risk of electric shock.

• When operating a power tool outdoors, use an

extension cord suitable for outdoor use. Use of

a cord suitable for outdoor use reduces the risk of

electric shock.

• If operating a power tool in a damp location is

unavoidable, use a ground fault circuit inter-

rupter (GFCI) protected supply. Use of an GFCI

reduces the risk of electric shock.

• Stay alert, watch what you are doing and use

common sense when operating a power tool. Do

not use a power tool while you are tired or under

the inﬂ uence of drugs, alcohol or medication. A

moment of inattention while operating power tools

may result in serious personal injury.

• Use personal protective equipment. Always

wear eye protection. Protective equipment such

as a dust mask, non-skid safety shoes, hard hat or

hearing protection used for appropriate conditions

will reduce personal injuries.

• Prevent unintentional starting. Ensure the

switch is in the o-position before connecting

to power source and/or battery pack, picking

up or carrying the tool. Carrying power tools with

your ﬁ nger on the switch or energizing power tools

that have the switch on invites accidents.

• Remove any adjusting key or wrench before

turning the power tool on. A wrench or a key left

attached to a rotating part of the power tool may

result in personal injury.

• Do not overreach. Keep proper footing and bal-

ance at all times. This enables better control of the

power tool in unexpected situations.

• Dress properly. Do not wear loose clothing or

jewelry. Keep your hair and clothing away from

moving parts. Loose clothes, jewelry or long hair

can be caught in moving parts.

• If devices are provided for the connection of

dust extraction and collection facilities, ensure

these are connected and properly used. Use of

dust collection can reduce dust-related hazards.

• Do not let familiarity gained from frequent use of

tools allow you to become complacent and ig-

nore tool safety principles. A careless action can

cause severe injury within a fraction of a second.

• Do not force the power tool. Use the correct

power tool for your application. The correct

power tool will do the job better and safer at the

rate for which it was designed.

• Do not use the power tool if the switch does not

turn it on and o. Any power tool that cannot be

controlled with the switch is dangerous and must

be repaired.

• Disconnect the plug from the power source and/

or remove the battery pack, if detachable, from

the power tool before making any adjustments,

changing accessories, or storing power tools.

Such preventive safety measures reduce the risk

of starting the power tool accidentally.

• Store idle power tools out of the reach of chil-

dren and do not allow persons unfamiliar with

the power tool or these instructions to operate

the power tool. Power tools are dangerous in the

hands of untrained users.

• Maintain power tools and accessories. Check

for misalignment or binding of moving parts,

breakage of parts and any other condition that

may aect the power tool’s operation. If dam-

aged, have the power tool repaired before use.

Many accidents are caused by poorly maintained

power tools.

• Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting edges

are less likely to bind and are easier to control.

• Use the power tool, accessories and tool bits

etc. in accordance with these instructions, tak-

ing into account the working conditions and

the work to be performed. Use of the power tool

for operations dierent from those intended could

result in a hazardous situation.

• Keep handles and grasping surfaces dry, clean

and free from oil and grease. Slippery handles

and grasping surfaces do not allow for safe handling

and control of the tool in unexpected situations.

WARNING Read all safety warnings, instructions, illustrations and speciﬁ cations provided

with this power tool. Failure to follow all instructions listed below may result in electric shock, ﬁ re

and/or serious injury. Save all warnings and instructions for future reference. The term "power tool" in

the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

• Have your power tool serviced by a qualiﬁ ed

repair person using only identical replacement

parts. This will ensure that the safety of the power

tool is maintained.

Your risk from these exposures varies, depending

on how often you do this type of work. To reduce

your exposure to these chemicals: work in a well

ventilated area, and work with approved safety

equipment, such as those dust masks that are

specially designed to ﬁ lter out microscopic particles.

FUNCTIONAL DESCRIPTION

Typical Operation

1. Check the work surface to make sure it is clean

and free of foreign materials.

Paint, rust, scale or uneven surfaces decrease

the holding strength of the magnet. Chips, burrs,

dirt and other foreign materials on the surface

of the magnetic base will also decrease holding

power. Use a smooth, ﬂ at ﬁ le to keep the magnet

clean and free of nicks.

The 4272-21 drill attaches to 3/8" or thicker

ferrous stock, and the 4274-21 to 1/4" or

thicker ferrous stock. Do not use on stock

less than 1/4". The magnetic base WILL NOT

hold on nonmagnetic grades of stainless steel.

2. To install/remove cutter:

A. Unplug tool.

B. Raise the drill motor to its highest position

on the slide rail.

C. Twist the quick-change arbor. Insert the cut-

ter into the arbor and release collar. Tug on

cutter to ensure it is secure. Cutter should

be fully seated into spindle.

D. Reverse procedure to remove cutter.

NOTE: Do not remove cutter unless slug is

removed. Slug may eject unexpectedly. Avoid

contact with cutter tips. Periodically inspect the

cutter tips for loose or damaged tips.

GROUNDING

WARNING Improperly connecting the

grounding wire can result in the risk of elec-

tric shock. Check with a qualiﬁ ed electrician

if you are in doubt as to whether the outlet is

properly grounded. Do not modify the plug

provided with the tool. Never remove the

grounding prong from the plug. Do not use

the tool if the cord or plug is damaged. If

damaged, have it repaired by a MILWAUKEE

service facility before use. If the plug will not

ﬁ t the outlet, have a proper outlet installed by

a qualiﬁ ed electrician.

Grounded Tools: Tools with Three Prong Plugs

Tools marked “Grounding Required” have a three

wire cord and three prong grounding plug. The

plug must be connected to a properly grounded

outlet (See Figure A). If the tool should electrically

malfunction or break down, grounding provides a

low resistance path to carry electricity away from

the user, reducing the risk of electric shock.

The grounding prong in the plug is connected

through the green wire inside the cord to the

grounding system in the tool. The green wire in the

cord must be the only wire connected to the tool's

grounding system and must never be attached to

an electrically “live” terminal.

Your tool must be plugged into

an appropriate outlet, properly

installed and grounded in accord-

ance with all codes and ordinances.

The plug and outlet should look like

those in Figure A.

Double Insulated Tools:

Tools with Two Prong Plugs

Tools marked “Double Insulated” do not require

grounding. They have a special double insula-

tion system which satisﬁ es OSHA requirements

and complies with the applicable standards of

Underwriters Laboratories, Inc.,

the Canadian Standard Asso-

ciation and the National Elec-

trical Code. Double Insulated

tools may be used in either of

the 120 volt outlets shown in

Figures B and C.

Grounded tools require a three wire extension

cord. Double insulated tools can use either a two

or three wire extension cord. As the distance from

the supply outlet increases, you must use a heavier

gauge extension cord. Using extension cords with

inadequately sized wire causes a serious drop in

voltage, resulting in loss of power and possible tool

damage. Refer to the table shown to determine the

required minimum wire size.

The smaller the gauge number of the wire, the

greater the capacity of the cord. For example, a 14

gauge cord can carry a higher current than a 16

gauge cord. When using more than one extension

cord to make up the total length, be sure each cord

contains at least the minimum wire size required.

If you are using one extension cord for more than

one tool, add the nameplate amperes and use the

sum to determine the required minimum wire size.

Guidelines for Using Extension Cords

• If you are using an extension cord outdoors, be

sure it is marked with the sufﬁ x “W-A” (“W” in

Canada) to indicate that it is acceptable for outdoor

use.

• Be sure your extension cord is properly wired

and in good electrical condition. Always replace a

damaged extension cord or have it repaired by a

qualiﬁ ed person before using it.

• Protect your extension cords from sharp objects,

excessive heat and damp or wet areas.

READ AND SAVE ALL

INSTRUCTIONS FOR FUTURE USE.

* Based on limiting the line voltage drop to ﬁ ve volts at

150% of the rated amperes.
