PERSONAL SAFETY
GENERAL POWER TOOL SAFETY WARNINGS
WORK AREA SAFETY
ELECTRICAL SAFETY
• Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
• 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.
• Keep children and bystanders away while
operating 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 elec-
tric 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 residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
under the infl uence of drugs, alcohol or medi-
cation. 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.
WARNING READ ALL SAFETY WARNINGS AND INSTRUCTIONS.
Failure to follow the warnings and instructions 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.
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
• 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

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.
BATTER Y T OOL USE AND CARE
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.
• Recharge only with the charger specifi ed by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of fi re
when used with another battery pack.
• Use power tools only with specifi cally desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and fi 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 termi-
nals together may cause burns or a fi re.
• Under abusive conditions, liquid may be ejected from the battery, avoid contact. If contact
accidentally occurs, fl ush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation or burns.
SPECIFIC SAFETY RULES
1. 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 sur-
faces 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 ac-
curacy 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.
2. Causes and Operator Prevention of KICK-
BACK:
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 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 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 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, 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 kickback
from the workpiece as the saw is restarted.
Support large panels to minimize 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. Unsharp-
ened or improperly set blades produce narrow
kerf causing excessive friction, blade binding
and kickback.
Blade depth and bevel adjusting locking le-
vers 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.
3. 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 position. 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 slug-
gishly due to damaged parts, gummy deposits,
or a buildup of debris.
Lower guard should be retracted manually
only for special cuts such as "plunge cuts"
("pocket 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.
4. Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.
5. 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 cement and
other masonry products, and
• arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies, depend-
ing 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.

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, or cutting slot, 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 operator.
KICKBACK is the result of tool misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below:
1. Maintain a fi rm grip with both hands on the
saw and position your body and arm to allow
you to resist KICKBACK forces. KICKBACK
forces can be controlled by the operator, if
proper precautions are taken.
2. 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.
3. When restarting a saw in the workpiece,
center the saw blade in the kerf, or cut, 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.
4. Support large panels to minimize 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.
5. Do not use dull or damaged blades. Unsharp-
ened or improperly set blades produce narrow
kerf causing excessive friction, blade binding
and KICKBACK.
6. 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.
7. Use extra caution when making a “Pocket
Cut” into existing walls or other blind areas.
The protruding blade may cut objects that can
cause KICKBACK.
8. Set the depth of cut for no more than 1/8" to
1/4" greater than the thickness of the stock.
The less blade exposed, the less chance of
binding and KICKBACK. Before cutting, be sure
depth and bevel adjustments are tight.
9. 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.
10. Use a rip fence or edge guide when ripping.
Guides improve control and reduce blade binding.
11. Stay alert. Any distraction can cause twisting
or binding. Repetitive cuts may lull the user into
careless movements.
General Operation
Always clamp the workpiece securely on a saw
horse or bench (Fig. 10). See “APPLICATIONS”
for the correct way to support your work in different situations.
Fig. 11
10
11
1. Draw a cutting line. Place the front of the shoe
on the edge of the workpiece without making
blade contact. Hold the handle with one hand
and the front handle with the other (Fig. 12).
Electric Brake
The electric brake engages when the trigger is
released, causing the blade to stop and allowing
you to proceed with your work. Generally, the saw
blade stops within two seconds. However, there
may be a delay between the time you release the
trigger and when the brake engages. Occasionally
the brake may miss completely. If the brake misses
frequently, the saw needs servicing by an authorized MILWAUKEE service facility. The brake is not
a substitute for the guard, and you must always wait
for the blade to stop completely before removing
the saw from the workpiece.
Cold Weather Operation
The V28 Lithium-Ion battery pack can be used in
temperatures down to -4°F . When the battery pack
is very cold, it may pulse for the fi rst minute of use
to warm itself up. Put the battery pack on a tool
and use the tool in a light application. After about
a minute, the pack will have warmed itself up and
operate normally.
Troubleshooting
If the blade does not follow a straight line:
• T eeth are dull. This is caused by hitting a hard
object such as a nail or stone, dulling teeth on
one side. The blade tends to cut to the side
with the sharpest teeth.
• Shoe is out of line or bent
• Blade is bent
• Rip fence or guide is not being used
If the 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
• Incorrect blade is being used
Fig. 12
2. Line up the sight line with your cutting line.
Position your arms and body to resist KICKBACK.
3. T o start the saw, push the lock-of f button down
while pulling the trigger. Allow the motor to
reach full speed before beginning cut.
4. While cutting, keep the shoe fl at against the
workpiece and maintain a fi rm grip. Do not
force the saw through the workpiece. Forcing
a saw can cause KICKBACK.
5. If making a partial cut, restarting in mid-cut or
correcting direction, allow the blade to come
to a complete stop. To resume cutting, center
the blade in the kerf, back the saw away from
cutting edge a few inches, push the lock-off
button down while pulling the trigger and reenter the cut slowly.
6. If the saw binds and stalls, maintain a fi rm grip
and release the trigger immediately. Hold the
saw motionless in the workpiece until the blade
comes to a complete stop.
7. After fi nishing a cut, be sure the lower guard
closes and the blade comes to a complete stop
before setting the saw down.
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
workpiece, the blade will tend to bind, causing
KICKBACK.
Support large panels. Be sure to set the depth of
the cut so that you only cut through the workpiece,
not through the supports.
Fig. 13
APPLICATIONS
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® reciprocating saw or jig
saw for this type of cut. However, if you must use a
circular saw to make a pocket cut, USE EXTREME
CAUTION. To maintain control of the saw during
pocket cutting, keep both hands on the saw.
1. Beginning at a corner, line up the sight line with
your cutting line. Tilt the saw forward, fi rmly
fi xing the front of the shoe on the workpiece
(Fig. 14). The blade should be just above cutting
line, but not touching it. Raise the lower guard
using the lower guard lever.
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. To install the rip fence, slide
the bar through the rip fence slot in either side of
the shoe. The width of the cut is the distance from
the inside of the blade to the inside edge of the rip
fence. Adjust the rip fence for the desired width,
and lock the setting by tightening the rip fence
adjusting knob.
When ripping widths greater than 4", clamp or tack
1" lumber to workpiece and use the inside edge of
the shoe as a guide.
Cross-Cutting Wood
Cross-cutting is cutting across the grain. Select the
proper blade for your job. Advance the saw slowly
to avoid splintering the wood.
Fig. 14
Fig. 15
WARNING To reduce the risk of elec-
tric shock, check work area for hidden pipes
and wires before making pocket cuts.
2. To start the saw, push the lock-off button down
while pulling the trigger. Allow the motor to reach
full speed before beginning cut. Using the front
of the shoe as a hinge point, gradually lower the
back end of the saw into the workpiece (Fig. 15).
Fig. 16
3. When the shoe rests fl at against workpiece,
advance the saw to the far corner (Fig. 16).
Release the trigger and allow the 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® reciprocating saw,
jig saw or small hand saw to fi nish the corners
if they are not completely cut through.
Release the lower guard lever and grasp the
front handle.
