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, re and/or serious injury.
Save
all warnings and instructions for future reference. The term “power tool” in the warn-
ings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
• Keep work area clean and well lit. Cluttered or
WORK AREA SAFETY
dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, 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 inter-
rupter (GFCI) protected supply. Use of an GFCI
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 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 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 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 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. 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 qualied
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.

SPECIFIC SAFETY RULES
Cutting procedures
•
DANGER: Keep hands away from cutting
area and the 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 the power tool by insulated gripping
surfaces only, 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 power
tool “live” and could give the operator an electric
shock.
• 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 arbour 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 washers
or bolt. The blade washers and bolt were specially
designed for your saw, for optimum performance
and safety of operation.
Further safety instructions for all saws
Kickback causes and related warnings
– 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 reaction 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 the operator.
Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can
be avoided by taking proper precautions as given
below:
• Maintain a 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 jump backwards, but kickback 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
corrective actions to eliminate the cause of blade
binding.
• When restarting a saw in the workpiece, centre
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 kickback 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 blades. Unsharp-
ened or improperly set blades produce narrow
kerf causing 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 sawing into existing
walls or other blind areas. The protruding blade
may cut objects that can cause kickback.
Lower guard function
• Check lower guard for proper closing before
each use. Do not operate the saw if lower guard
does not move freely and close instantly. Never
clamp or tie the lower guard into the open
position. If saw is accidentally dropped, lower
guard may be bent. Raise the lower guard with the
retracting handle 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 damaged parts, gummy deposits, or a build-up of
debris.
• Lower guard should be retracted manually
only for special cuts such as “plunge cuts”
and “compound cuts.” Raise lower guard by
retracting handle 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 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.
• 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
4
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.
GROUNDING
WARNING Improperly connecting the
grounding wire can result in the risk of electric
shock. Check with a qualied 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 t the outlet,
have a proper outlet installed by a qualied
electrician.
Some models are provided with a 20 amp locking
plug (NEMA L5-20).
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 Figures A and B). 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.
EXTENSION CORDS
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.
READ AND SAVE ALL
INSTRUCTIONS FOR FUTURE USE.
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 parti-
cles.
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
Fig. A
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 accordance with all codes and
Fig. B
ordinances. The plug and outlet
should look like those in Figures A and B.
Double Insulated Tools:
Tools with Two Prong Plugs
Tools marked “Double Insulated” do not require
grounding. They have a special double insulation system which satis-
es OSHA requirements and
complies with the applicable
standards of Underwriters
Laboratories, Inc., the Canadian Standard Association and
the National Electrical Code.
Double Insulated tools may
Fig. C Fig. D
be used in either of the 120 volt outlets shown in
Figures C and D.
Guidelines for Using Extension Cords
• If you are using an extension cord outdoors,
be sure it is marked with the sufx “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 qualied person before using it.
• Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.

NOTE: This procedure will not show proper lower
guard operation if the tool is not on its side.
3. Grasp the lower guard by the sides and push it
all the way back into the blade housing.
4. Release the lower guard.
• If the guard immediately springs back into
place, it is working correctly and you may
continue with use.
• If the guard does not immediate spring back
into place, clean the upper and lower guards
to remove all chips and debris. Then, check
the operation again by starting with step 1.
• If the guard still does not immediately spring
back into place, contact a MILWAUKEE service
facility for repairs.

blade, but not in line with the blade. Kickback
could cause the saw to jump backwards, but kickback forces can be controlled by the operator, if
proper precautions are taken.
Fig. 5
Kickback
• 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 corrective actions to eliminate the cause of
blade binding.
• When restarting a saw in the workpiece, centre
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 kickback from
the workpiece as the saw is restarted.
Fig. 6
WARNING To reduce the risk of in-
jury, wear safety goggles or glasses with side
shields.
Kickback causes and related warnings
– 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 reaction 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

Troubleshooting
If blade does not want to follow straight line:
• Teeth are dull on one side. This is caused by
hitting a hard object such as a nail or stone,
dulling teeth on one side. The blade wants to
cut to the side with the sharpest teeth.
• Shoe is out of line or bent
• Blade is bent
• Failure to use rip fence or guide

General Operation
Always clamp workpiece securely on a saw horse
or bench. See “Applications” for the correct way to
support your work in different situations. A typical
application is shown below.
1. Draw cutting line. Place front of shoe on edge of
workpiece without making blade contact. Hold
switch handle with one hand and top handle with
the other.
2. Line up sighting notch with your cutting line.
Position arms and body to resist kickback. Pull
trigger, allowing motor to reach full speed before
beginning cut.
3. While cutting, keep shoe at against workpiece
and maintain a rm grip. Do not force saw through
the work. Forcing a saw can cause kickback.
4. If making a partial cut, restarting in mid-cut or
correcting direction, allow blade to come to a
complete stop. To resume cutting, center blade
in kerf, back saw away from cutting edge a few
inches, pull trigger and re-enter cut slowly.
5. If saw stalls, maintain a rm grip and release
trigger immediately. Correct problem before
continuing (see “Preventing Kickback”).
6. After nishing a cut, be sure lower guard closes
and blade comes to a complete stop before setting down saw.

APPLICATIONS
WARNING To reduce the risk of explo-
sion, electric shock and property damage,
always check the work area for hidden pipes
and wires before drilling.
Cutting Large Panels
Large panels and long boards sag or bend if they
are not correctly supported. If you attempt to cut
without leveling and properly supporting the piece,
the blade will tend to bind, causing kickback.
Support large panels. Be sure to set the depth of
cut so that you cut through workpiece only and not
through the supports.
Fig. 11
Ripping Wood
Ripping is cutting lengthwise with the grain. Select
the proper blade for your job. Use a rip fence for
rips 4" wide or less (Fig. 12). To install a rip fence,
slide the bar through the rip fence slot in either side
of the shoe. Adjust for desired width by lining up
the selected measurement with the sighting notch
and lock setting with thumb screw.
Fig. 12
When ripping widths greater than 4", clamp or tack
1" lumber to the workpiece as a guide (Fig. 13).
Fig. 13
Cross-Cutting Wood
Cross-cutting is cutting across the grain. Select the
proper blade for your job. Advance saw slowly to
avoid the tendency of wood bers to tear and lift.
Fig. 14
Pocket Cutting
Pocket cuts are made in the middle of the workpiece when it can not be cut from an edge. We
recommend using a Sawzall
However, if you must use a circular saw to make a
pocket cut, USE EXTREME CAUTION.
1. Beginning at a corner, line up sighting notch with
your cutting line. Tilt saw forward, rmly xing
front of shoe on workpiece. Blade should be
just above cutting line, but not touching it. Raise
lower guard using lower guard lever.
2. Pull trigger. Allow the blade to come to full speed.
Using front of shoe as a hinge point, gradually
lower back end of saw into workpiece (Fig. 15).

3. When shoe rests at against workpiece (Fig. 16),
move saw to far corner. Release trigger and
allow blade to come to a complete stop before
removing it from workpiece. Repeat the above
steps for each side of the opening. Use a Saw-
®
zall
, jig saw, or small hand saw to nish corners
if they are not completely cut through.

Cutting Masonry and Metal
MILWAUKEE circular saws are not intended for
continuous use in cutting metal or masonry. When
cutting these materials, use the correct blade. MIL-
WAUKEE does not recommend using bonded abrasive wheels on circular saws for any application.
WARNING Dust, chips, and grit can
cause guard to hang up at any time. If saw
is used to cut masonry or metal, reserve and
mark it for that purpose only and return it to a
MILWAUKEE service facility for cleaning and
testing before using it for wood cutting.
WARNING Do not use tool for cutting
metal near ammable material. Sparks may
cause re.
When cutting metal, use a metal cutting blade. Set
depth of cut to full depth. Protect everyone in the
area from sparks.
Fig. 18
WARNING Only use accessories with
maximum speed rating at least as high as
nameplate RPM of tool.
When cutting masonry, use a diamond blade. Make
successive passes at depths of less than 1/4" to
achieve the desired depth. Cutting at a depth of
more than 1/4" will damage wheel. Unplug the tool
and frequently clean dust from air vents and guards.

Keep your tool in good repair by adopting a regular
maintenance program. Before use, examine the
general condition of your tool. Inspect guards,
switches, tool cord set and extension cord for
damage. Check for loose screws, misalignment,
binding of moving parts, improper mounting, broken parts and any other condition that may affect
its safe operation. If abnormal noise or vibration
occurs, turn the tool off immediately and have the
problem corrected before further use. Do not use a
damaged tool. Tag damaged tools “DO NOT USE”
until repaired (see “Repairs”).
Under normal conditions, relubrication is not necessary until the motor brushes need to be replaced.
After six months to one year, depending on use,
return your tool to the nearest MILWAUKEE service
facility for the following:
• Lubrication
• Brush inspection and replacement
• Mechanical inspection and cleaning (gears,
spindles, bearings, housing, etc.)
• Electrical inspection (switch, cord, armature, etc.)
• Testing to assure proper mechanical and electri-
cal operation
Maintaining Oil Level
Check oil level before use. To check level, set saw
for maximum depth, rest it at on its shoe and check
oil level window. Oil level should be below max oil
level line on tool (about 1/2 oz.).
If oil level is low:
1. Add oil by setting the saw on its shoe and removing the oil plug.
2. Pour oil into the chamber. DO NOT OVERFILL.
3. When the proper oil level is reached, replace oil
plug.
MILWAUKEE oil is a synthetic oil specically en-
gineered for worm drive saws. Substitute oils may
cause damage to the tool and be unsatisfactory in
various temperatures. Check oil level frequently
when using tool for extended hours. (Caution: Oil
may be hot.)
WARNING To reduce the risk of injury,
electric shock and damage to the tool, never
immerse your tool in liquid or allow a liquid to
ow inside the tool.
Cleaning
Clean dust and debris from vents. Keep the tool
handles clean, dry and free of oil or grease. Use
only mild soap and a damp cloth to clean your tool
since certain cleaning agents and solvents are
harmful to plastics and other insulated parts. Some
of these include: gasoline, turpentine, lacquer thinner, paint thinner, chlorinated cleaning solvents,
ammonia and household detergents containing
ammonia. Never use ammable or combustible
solvents around tools.
Repairs
If your tool is damaged, return the entire tool to the
nearest service center.

hazardous.
