GENERAL SAFETY RULES — FOR ALL POWER TOOLS
POWER TOOL USE AND CARE
SPECIFIC SAFETY RULES
WARNING
READ ALL INSTRUCTIONS
Failure to follow all instructions listed below may result in electric shock, fi re and/or
serious injury. The term “power tool” in all of the warnings listed below refers to your
mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
WORK AREA SAFETY
1. Keep work area clean and well lit. Clut-
tered or dark areas invite accidents.
2. Do not operate power tools in explosive
atmospheres, such as in the presence
of fl ammable liquids, gases, or dust.
Power tools create sparks which may
ignite the dust or fumes.
3. Keep children and bystanders away
while operating a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
4. 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.
5. 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.
6. Do not expose power tools to rain
or wet conditions. Water entering a
power tool will increase the risk of electric
shock.
7. 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.
8. 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.
2 3
PERSONAL SAFETY
9. Stay alert, watch what you are do-
ing 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.
10. Use safety equipment. Always wear
eye protection. Safety equipment such
as dust mask, non-skid safety shoes,
hard hat, or hearing protection used
for appropriate conditions will reduce
personal injuries.
11. Avoid accidental starting. Ensure the
switch is in the off-position before plugging in. Carrying tools with your fi nger on
the switch or plugging in power tools that
have the switch on invites accidents.
12. 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.
13. Do not overreach. Keep proper foot-
ing and balance at all times. This
enables better control of the power tool
in unexpected situations.
14. Dress properly. Do not wear loose
clothing or jewellery. Keep your hair,
clothing and gloves away from moving
parts. Loose clothes, jewellery, or long
hair can be caught in moving parts.
15. If devices are provided for the connec-
tion of dust extraction and collection
facilities, ensure these are connected
and properly used. Use of these de-
vices can reduce dust-related hazards.
16. 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.
17. 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.
18. 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 preven-
tive safety measures reduce the risk of
starting the tool accidentally.
19. Store idle power tools out of the
reach of children and do not allow
persons unfamiliar with the power
tools or these instructions to operate
power tools. Power tools are danger-
ous in the hands of untrained users.
20. 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.
21. Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to
bind and are easier to control.
22. Use the power tool, accessories and
tool bits etc., in accordance with
these instructions and in the manner
intended for the particular type of
power tool, 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
23. 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.
DANGER:
1. 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.
2. Do not reach underneath the work-
piece. The guard cannot protect you from
the blade below the workpiece.
3. Adjust the cutting depth to the thick-
ness of the workpiece. Less than a full
tooth of the blade teeth should be visible
below the workpiece.
4. 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.
5. Hold power tools 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 make exposed metal parts
of the tool “live” and shock the operator.
6. When ripping always use a rip fence or
straight edge guide. This improves the
accuracy of cut and reduces the chance
of blade binding.
7. 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.
8. 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.
9. 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 reaction drives the
unit rapidly back toward the operator.
If the blade becomes twisted or mis-
aligned 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:
a. 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 jump
backwards, but kickback forces can
be controlled by the operator, if proper
precautions are taken.
b. When blade is binding, or when inter-
rupting 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 cor-
rective actions to eliminate the cause
of blade binding.
c. When restarting a saw in the work-
piece, 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.
d. 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.
e. Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding and kickback.
f. 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.
g. Use extra caution when making a
“plunge cut” into existing walls or
other blind areas. The protruding
blade may cut objects that can cause
kickback.
10. 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 acciden-
tally 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.
11. 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.
12. 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 saw-
ing, the lower guard should operate
automatically.
13. 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.
14. Do not use abrasive wheels with
circular saws. Dust and grit can cause
lower guard to hang up and not operate
properly.
15. Maintain labels and nameplates.
These carry important information.
If unreadable or missing, contact a
MILWAUKEE service facility for a free
replacement.
16. WARNING: Some dust created by
power sanding, sawing, grinding, drilling, and other 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 ce-
ment and other masonry products,
and
• arsenic and chromium from chemi-
cally-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 specifi cally designed to
fi lter out microscopic particles.

Improperly connecting the grounding
wire can result in the risk of electric
shock. Check with a qualifi ed electri-
cian 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.
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.
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
accordance with all codes and ordinances.
The plug and outlet should look like those in
Figures A and B.
Fig. A
WARNING
GROUNDING
Fig. 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 satisfies
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 be used
in either of the 120 volt outlets shown in
Figures C and D.
Fig. C
Fig. D
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.
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.

WARNING
To reduce the risk of injury, always
unplug tool before attaching or
removing accessories or making
adjustments. Use only specifi cally
recommended accessories. Others
may be hazardous.
WARNING
Only use accessories with maximum speed rating at least as high
as nameplate RPM of tool.
Selecting Blade
Always use sharp blades. Dull blades tend to
overload the tool and increase the chance of
kickback (see “Preventing Kickback”). A combination blade is included with your tool for
general use in wood. Select the right blade
for your job. Only use blades with diamond
arbors, and read the manufacturer’s instructions before use.

blade, which could cause a saw that is not
under control to lift up and out of the workpiece towards the user. Take the precautions
below to help prevent kickback.
1. Maintain a fi rm grip and correct body po-
sition. Position arms and body to control
the upward and backward reaction force
of kickback (Fig. 5).
Fig. 5
Adjusting Depth
1. To adjust depth of cut, place saw on edge
of workbench and pull up depth adjusting
lever.
2. Keeping shoe fl at against workbench,
raise or lower saw to desired position.
Lowering saw will increase depth of cut.
Raising saw will decrease depth of cut.
For proper depth setting, blade should
extend no more than 1/4" below material
being cut. Use the depth of cut scale for
standard depths.
3. Push down depth adjusting lever to lock.
Check to be sure depth adjusting lever is
secure.
Adjusting Miter Angle
1. To adjust angle of cut, place saw on edge
or workbench and pull up miter adjusting
lever.
2. Hold down shoe and slide saw to desired
position (up to 45˚) according to markings
on miter scale.
2. Keep blades sharp and clean. A sharp
blade will tend to cut its way out of a
pinching condition. A dull blade produces
a narrow kerf (path cut by blade) and is
likely to be pinched by the workpiece.
Dull or pitch coated blades also tend
to encourage the user to force the saw,
causing reduced control and blade binding. Any blade with a small set, even
though it is sharp, may be likely to kick
back (Fig. 6).

3. Set the depth of cut for no more than 1/8"
to 1/4" greater than the thickness of the
stock (Fig. 7). The less blade exposed,
the less chance of binding and kickback.
Before cutting, be sure depth and miter
adjustments are tight.
Fig. 7
1/8" - 1/4"
4. Be cautious of pitchy, knotty, wet or
warped stock. These are most likely to
create pinching conditions and possible
kickback. Do not rip warped lumber. Avoid
cutting nails.
5. Support workpiece properly. Improperly
supported material can sag or bow, pinching the blade. When cutting down the
center of your workpiece, support material
on both sides of the cut. Large sheets of
thin material such as paneling, formica,
etc. must be well supported over their
entire length (Fig. 8) (see “Cutting Large
Panels”). When cutting the end off of your
workpiece, rest the saw on the supported
portion outside of the supports and allow
the cut off end to fall away (see “General
Operation”).
Fig. 8
6. Always allow blade to come to a full
stop before removing the saw from
the workpiece. Never remove the saw
from a cut while the blade is moving.
If restarting or correcting direction in
mid-cut, allow blade to coast to a stop,
back saw up a few inches and center it
in the kerf before restarting.
7. Stay alert. Any distraction can cause
twisting or binding. Repetitive cuts may
lull the user into careless movements.
8. Use care when making bevel cuts.
Because of the increased amount of
blade engagement with the work and
decreased stability of the shoe when
making bevel cuts, kickback may occur
if improperly used. Keep shoe fi rmly
against workpiece.
Fig. 9
9. Do not force tool. Forcing a saw reduces
control and cutting effi ciency.
10. Use rip fence or edge guide when ripping. Guides improve control and reduce
blade binding (see “Ripping Wood”).
If kickback should occur, continue to grip the
saw fi rmly and immediately release trigger.
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.

a saw can cause kickback.
4. If making a partial cut, restarting in midcut 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 fi rm grip and
release trigger immediately. Correct problem before continuing (see “Preventing
Kickback”).
6. After fi nishing a cut, be sure lower guard
closes and blade comes to a complete
stop before setting down saw.
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
If blade binds, smokes, or turns blue from
friction:
• Blade is dull
• Blade is on backwards
• Blade is bent
• Blade is dirty
• Workpiece is not properly supported
• Failure to use correct blade

To reduce the risk of explosion,
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.

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
WARNING
APPLICATIONS
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
fi 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
this type of cut. 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, fi rmly fi 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).

WARNING
MAINTENANCE
3. When shoe rests fl 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 Sawzall®, jig
saw, or small hand saw to fi nish corners
if they are not completely cut through.
Fig. 16
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. MILWAUKEE 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.
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.
Fig. 17
WARNING
Do not use tool for cutting metal
near fl ammable material. Sparks
may cause fi 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
To reduce the risk of injury , always unplug your tool before performing any
maintenance. Never disassemble the
tool or try to do any rewiring on the
tool’s electrical system. Contact a
MILWAUKEE service facility for ALL
repairs.
Maintaining Tools
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. T ag 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
electrical operation
Maintaining Oil Level
Check oil level before use. To check level,
set saw for maximum depth, rest it fl 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 OVER
FILL.
3. When the proper oil level is reached,
replace oil plug.
MILWAUKEE oil is a synthetic oil specifi cally
engineered 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 periods. (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 fl 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 fl ammable or
combustible solvents around tools.
Repairs
If your tool is damaged, return the entire tool
to the nearest service center.
