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.

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 off-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 off.
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 affect 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 different 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.
