GENERAL POWER TOOL SAFETY WARNINGS
WARNING
READ ALL SAFETY WARNINGS AND ALL INSTRUCTIONS.
Failure to follow the warnings and instructions may result in electric shock, fi re and/or
Save all warnings and instructions for future reference
serious injury.
The term "power tool" in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
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 fl 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. 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 residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
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 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 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 energising 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
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewel-
lery 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.
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 the battery pack 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. 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.
SERVICE
• 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.

SPECIFIC SAFETY RULES
DANGER:
• Keep hands away from cutting area and blade.
Keep your second hand on auxiliary handle or
motor housing. If both hands are holding the saw,
they cannot be cut by the blade.
• Do not reach underneath the workpiece. The guard
cannot protect you from the blade below the workpiece.
• Adjust the cutting depth to the thickness of
the workpiece. Less than a full tooth of the blade
teeth should be visible below the workpiece.
• NEVER hold piece being cut in your hands
or across your leg. Secure the workpiece to
a stable platform. It is important to support the
work properly to minimize body exposure, blade
binding, or loss of control.
• Hold power tool by insulated gripping surfaces
when performing an operation where the cutting
tool may contact hidden wiring or its own cord.
Contact with a "live" wire will also make exposed
metal parts of the tool "live" and shock the operator.
• When ripping always use a rip fence or straight
edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
• Always use blades with correct size and shape
(diamond versus round) of arbor holes. Blades
that do not match the mounting hardware of the
saw will run eccentrically, causing loss of control.
• Never use damaged or incorrect blade wash-
ers or bolts. The blade washers and bolts were
specially designed for your saw, for optimum
performance and safety of operation.
Causes and Operator Prevention of KICKBACK:
KICKBACK is a sudden reaction to a pinched, bound
or misaligned saw blade, causing an uncontrolled saw
to lift up and out of the workpiece toward the operator.
When the blade is pinched or bound tightly by the kerf
closing down, the blade stalls and the motor reac-
tion drives the unit rapidly back toward the operator.
If the blade becomes twisted or misaligned in the
cut, the teeth at the back edge of the blade can dig
into the top surface of the wood causing the blade to
climb out of the kerf and jump back toward operator.
KICKBACK is the result of saw misuse and/or incor-
rect operating procedures or conditions and can be
avoided by taking proper precautions as given below:
• Maintain a fi rm grip with both hands on the
saw and position your arms to resist kickback
forces. Position your body to either side of the
blade, but not in line with the blade. Kickback
could cause the saw to jumb backwards, but kick-
back forces can be controlled by the operator, if
proper precautions are taken.
• When blade is binding, or when interrupting a
cut for any reason, release the trigger and hold
the saw motionless in the material until the
blade comes to a complete stop. Never attempt
to remove the saw from the work or pull the
saw backward while the blade is in motion or
kickback may occur. Investigate and take correc-
tive actions to eliminate the cause of blade binding.
• When restarting a saw in the workpiece, cen-
ter the saw blade in the kerf and check that
saw teeth are not engaged into the material.
If saw blade is binding, it may walk up or kick-
back from the workpiece as the saw is restarted.
• Support large panels to minimise the risk of
blade pinching and kickback. Large panels tend
to sag under their own weight. Supports must be
placed under the panel on both sides, near the line
of cut and near the edge of the panel.
• Do not use dull or damaged blade. Unsharpened
or improperly set blades produce narrow kerf caus-
ing excessive friction, blade binding and kickback.
• Blade depth and bevel adjusting locking levers
must be tight and secure before making cut. If
blade adjustment shifts while cutting, it may cause
binding and kickback.
• Use extra caution when making a "plunge cut"
(or pocket cut) into existing walls or other blind
areas. The protruding blade may cut objects that
can cause kickback.
• Check lower guard for proper closing before
each use. Do not operate saw if lower guard
does not move freely and close instantly. Never
clamp or tie the lower guard into the open posi-
tion. If saw is accidentally dropped, lower guard
may be bent. Raise the lower guard with the lower
guard lever and make sure it moves freely and
does not touch the blade or any other part, in all
angles and depths of cut.
• Check the operation of the lower guard spring.
If the guard and the spring are not operating
properly, they must be serviced before use.
Lower guard may operate sluggishly due to dam-
aged parts, gummy deposits, or a buildup of debris.
• Lower guard should be retracted manually only
for special cuts such as "plunge cuts" and
"compound cuts". Raise lower guard by lower
guard lever and as soon as blade enters the
material, the lower guard must be released. For
all other sawing, the lower guard should operate
automatically.
• Always observe that the lower guard is covering
the blade before placing saw down on bench or
fl oor. An unprotected, coasting blade will cause the
saw to walk backwards, cutting whatever is in its
path. Be aware of the time it takes for the blade to
stop after switch is released.
• Do not use abrasive wheels with circular saws.
Dust and grit can cause lower guard to hang up
and not operate properly.
• Maintain labels and nameplates. These carry im-
portant 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.
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 spe-
cifi cally designed to fi lter out microscopic particles.
