WARNING
SAFETY WARNINGS
Read all safety warnings, instruc-
tions provided with this power tool. Failure to
follow all instructions listed below may result in
electric shock, 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-oper-
ated (cordless) power tool.
tions, illustrations and specica-
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
• Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose
control.
ELECTRICAL SAFETY
• 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. Unmodied
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 conditions.
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 interrupter
(GFCI) protected suppl
the risk of electric shock.
y. Use of an GFCI reduces
PERSONAL SAFETY
• 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 inuence 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 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 balance
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 ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
POWER TOOL USE AND CARE
• 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 children 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 damaged, 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, taking 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.
BATTERY TOOL USE AND CARE
• Recharge only with the charger specied by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of re when used with
another battery pack.
• Use power tools only with specically designated
battery packs. Use of any other battery packs may
create a risk of injury and re.
• When battery pack is not in use, keep it away from
other metal objects, like paper clips, coins, keys,
nails, screws or other small metal objects, that can
make a connection from one terminal to another.
Shorting the battery terminals together may cause
burns or a re.
• Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally
occurs, ush with water. If liquid contacts eyes,
2
additionally seek medical help. Liquid ejected from
WARNING
the battery may cause irritation or burns.
• Do not use a battery pack or tool that is damaged or
modied. Damaged or modied batteries may exhibit
unpredictable behavior resulting in re, explosion or
risk of injury.
• Do not expose a battery pack or tool to re or
excessive temperature. Exposure to re or temperature
above 265°F (130°C) may cause explosion.
• Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specied in the instructions. Charging im-
properly or at temperatures outside the specied range
may damage the battery and increase the risk of re.
SERVICE
• Have your power tool serviced by a qualied repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.
• Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
SPECIFIC SAFETY RULES FOR
KNOCKOUT TOOL
• Use tool only as directed. Only trained personnel
should operate tool.
• Do not use in or near live electrical panels. Only
work on de-energized electrical panels. Disconnect all
electrical current before use to avoid the risk of electric
shock.
• Keep hands away from knockout die and punch while
tool is in use. Fingers could be crushed or severed.
• To reduce the risk of injury, wear safety goggles or
glasses with side shields. Before use, inspect and
discard workpieces and accessories with cracks
or damage. Shards from weakened metal could cause
injury.
• Avoid contact with punched metal edges. Edges
may be sharp and could cause injury.
• Do not attempt to punch through more than one
layer of material at a time. Punching through multiple
layers could cause the material and accessories to
warp break, throwing shards that could cause injury.
• Use tool only with knockout dies and punches
rated for the peak output force of this tool. Other
uses may cause injury or damage to the tool, accessories, and workpiece.
• Maintain labels and nameplates. These carry
important information. If unreadable or missing, contact
a MILWAUKEE service facility for a free replacement.
•
construction activities contains chemicals known to
cause cancer, 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.
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
lter out microscopic particles.
Some dust created by power sanding,
