POWER TOOL USE AND CARE
SERVICE
SPECIFIC SAFETY RULES
•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 flammable
liquids, gases or dust. Powertoolscreatesparks
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. Unmodified 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. Thereisanincreasedriskofelectric
shock if your body is earthed or grounded.
•Do not expose power tools to rain or wet con-
ditions. 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. Useof
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. UseofanRCDreduces
the risk of electric shock.
•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 influence 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
hearingprotection 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. Carryingpowertoolswith
yourfingerontheswitchorplugginginpowertools
that have the switch on invites accidents.
•Remove any adjusting key or wrench before
turning the power tool on. Awrench 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. Useof
these devices can reduce dust-related hazards.
•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 powertoolifthe 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 pre-
ventivesafetymeasuresreduce 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 operation. If damaged, have the
power tool repaired before use. Manyaccidents
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 workingconditions and
the work to be performed. Use of the power tool
for operations different from those intended could
result in a hazardous situation.
•Have your power tool serviced by a qualified
repair person using only identical replacement
parts. Thiswill ensure that the safety of thepower
tool is maintained.
Safety Warnings Common forAbrasive Cutting-
Off Operations:
•This power tool is intended to function as a cut-
of tool. Read all safety warnings, instructions,
illustrations and specifications provided with
this power tool. Failure to follow all instructions
listed below may result in electric shock, fire and/
or serious injury.
•Operations such as grinding, sanding, wire
brushing, or polishing arenot recommended to
be performed with this power tool. Operations
for which the power tool was not designed may
create a hazard and cause personal injury.
•Do not use accessories which are not specifi-
cally designed and recommended by the tool
manufacturer. Just because the accessory can
be attached to your power tool, it does not assure
safe operation.
•The rated speed of the accessory must be at
least equal to the maximum speed marked on
the power tool. Accessories running faster than
their rated speed can break and fly apart.
•The outside diameter and the thickness of your
accessory must be within the capacity rating
of your power tool. Incorrectlysized accessories
cannot be adequately guarded or controlled.
•The arbour size of wheels, flanges, backing
pads or any other accessory must properly
fit the spindle of the power tool. Accessories
with arbour holes that do not match the mounting
hardware of the power tool will run out of balance,
vibrateexcessivelyand may cause loss of control.
•Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad for
cracks, tear or excess wear, wire brush for
loose or cracked wires. If power tool or acces-
sory is dropped, inspect for damage or install
an undamaged accessory.After inspecting and
installing an accessory, position yourself and
bystanders away from the plane of the rotating
accessory and run the power tool at maximum
no-load speed for one minute. Damagedacces-
sorieswill normallybreakapartduring thistesttime.
•Wear personal protective equipment. Depend-
ing on application, use face shield, safety
goggles or safety glasses. As appropriate,
wear dust mask, hearing protectors, gloves
and work shop apron capable of stopping
small abrasive or workpiece fragments. The
eye protection must be capable of stopping
flying debris generated by various operations.
The dust mask or respirator must be capable of
filtrating particles generated by your operation.
Prolonged exposure to high intensity noise may
cause hearing loss.
•Keep bystanders a safe distance away from
work area. Anyone entering the work area must
wearpersonal protective equipment. Fragments
of workpiece or of a broken accessory may fly
away and cause injury beyond immediate area of
operation.
•Hold power tool by insulated gripping surfaces
only, when performing an operation where the
cutting accessory may contact hidden wiring
or its own cord. Cutting accessory contacting a
live wire may make exposed metal parts of the
power tool live and shock the operator.
•Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning accessory.
•Never lay the power tool down until the acces-
sory has come to a complete stop. Thespinning
accessorymay grab the surface and pull the power
tool out of your control.
•Do not run the power tool while carrying it at
your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the
accessory into your body.
•Regularly clean the power tool’s air vents. The
motor’s fan will draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
•Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
•Do not use accessories that require liquid
coolants. Usingwaterorotherliquidcoolantsmay
result in electrocution or shock.
Kickback and Related Warnings
-Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush or
anyotheraccessory.Pinchingorsnaggingcauses
rapidstalling of the rotating accessory which in turn
causes the uncontrolled power tool to be forced in
the direction opposite of the accessory’s rotation
at the point of the binding.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel
that is entering into the pinch point can dig into
the surface of the material causing the wheel to
climb out or kick out. The wheel may either jump
toward or away from the operator, depending on
direction of the wheel’s movement at the point of
pinching. Abrasive wheels may also break under
these conditions.
-Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below.
•Maintain a firm grip on the power tool and posi-
tion your body and arm to allow you to resist
kickback forces. Always use auxiliary handle,
if provided, for maximumcontrol over kickback
or torque reaction during start-up. Theoperator
can control torque reactions or kickback forces, if
proper precautions are taken.
•Never place your hand near the rotating acces-
sory. Accessory may kick back over your hand.
•Do not position your body in the area where
power tool will move if kickback occurs. Kick-
backwillpropel the tool in direction opposite tothe
wheel’s movement at the point of snagging.
•Use special care when working corners, sharp
edges etc. Avoid bouncing and snagging the
accessory. Corners, sharp edges or bouncing
have a tendency to snag the rotating accessory
and cause loss of control or kickback.
•Do not attach a saw chain woodcarving blade
or toothed saw blade. Such blades create fre-
quent kickback and loss of control.

Safety Warnings Specific forAbrasive Cutting-
Off Operations:
•Use only wheel types that are recommended
for your power tool and the specific guard
designed for the selected wheel. Wheels for
which the power tool was not designed can not
be adequately guarded and are unsafe.
•The guard must be securely attached to the
power tool and positioned for maximum safety,
so the least amount of wheel is exposed to-
wards the operator. The guard helps to protect
operator from broken wheel fragments and ac-
cidental contact with wheel.
•Wheels must be used only for recommended
applications. For example: do not grind with
the side of cut-off wheel. Abrasivecut-offwheels
are intended for peripheral grinding, side forces
appliedto these wheels may cause them toshatter.
•Always use undamaged wheel flanges that are
of correct size and shape for your selected
wheel. Proper wheel flanges support the wheel
thus reducing the possibility of wheel breakage.
Flanges for cut-off wheels may be different from
grinding wheel flanges.
•Do not use worn down wheels from larger
power tools. Wheelintendedforlarger power tool
isnotsuitableforthehigherspeedofa smaller tool
and may burst.
Additional Safety Warnings Specific for Abra-
sive Cutting-Off Operations:
•Do not jam the cut-off wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases
the loading and susceptibility to twisting or bind-
ing of the wheel in the cut and the possibility of
kickback or wheel breakage.
•Do not position your body in line with and
behind the rotating wheel. When the wheel, at
the point of operation, is moving away from your
body, the possible kickback may propel the spin-
ning wheel and the power tool directly at you.
•When wheel is binding or when interrupting a
cut for any reason, switch off the power tool
and hold the power tool motionless until the
wheel comes to acomplete stop. Never attempt
to remove the cut-off wheel from the cut while
the wheel is in motion otherwise kickback may
occur. Investigate and take corrective action to
eliminate the cause of wheel binding.
•Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully reenter the cut. The wheel may bind,
walk up or kickback if the power tool is restarted
in the workpiece.
•Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kick-
back. Large workpieces tend to sag under their
own weight. Supports must be placed under the
workpiece near the line of cut and near the edge
of the workpiece on both sides of the wheel.
•Use extra caution when making a “pocketcut”
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes,
electricalwiring or objects that can cause kickback.
Additional Safety Warnings
•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
cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
•lead from lead-based paint
•crystalline silica from bricks and cementandother
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-
cially designed to filter out microscopic particles.
WARNING To reduce the risk of injury,
avoid inhalation of dust generated by grind-
ing and cutting operations. Exposure to dust
may cause respiratoryailments. Use approved
NIOSH or OSHA respirators, safety glasses or
face shields, gloves and protective clothing.
Provide adequate ventilation toeliminate dust,
or to maintain dust level below the Threshold
Limit Value for nuisance dust as classified
by OSHA.
* The tool is supplied with both a 1" flange nut and a 20 mm flange nut. To ensure the wheel is properly secured,
always use the flange nut that matches the wheel arbor hole size.

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 Figure A). 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
appropriateoutlet, properly installed
and grounded in accordance with
all codes and ordinances. The plug
and outlet should look like those in
Figure A.
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
complieswith theapplicablestandardsof Underwrit-
ers Laboratories, Inc., the Cana-
dianStandardAssociationand the
National Electrical Code. Double
Insulated tools may be used in ei-
therof the 120 volt outlets shown in
Figures B and C. Fig. B Fig. C
Fig. A
GROUNDING
WARNING Improperly connecting the
grounding wire can result in the risk of elec-
tric shock. Check with a qualified 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
fit the outlet, have a proper outlet installed by
a qualified electrician.
ASSEMBLY
WARNING To reduce the risk of injury,
always unplug tool before attaching or remov-
ing accessories or making adjustments. Use
only specifically recommended accessories.
Others may be hazardous.
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
thesupplyoutletincreases, 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 possibletool
damage.Refer to the table shown todetermine 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
sureit is marked with the suffix“W-A”(“W” in Cana-
da)toindicate 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
qualified person before using it.
•Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.
READ AND SAVE ALL
INSTRUCTIONS FOR FUTURE USE.
* Based on limiting the line voltage drop to five volts at
150% of the rated amperes.

metal and non-metallic materials. To reduce
the risk of injury, DO NOT cut wood. DO NOT
attempt to install a toothed blade on the tool.
DO NOT use with liquids or in damp locations.
2. Set the depth of cut for no more than neces-
sary. The less wheel exposed, the less chance
of binding and kickback. Before cutting, be sure
shoe assembly is tight.
3. Always allow the wheel to come to a full stop
before removing the cut-off machine from the
workpiece. Never remove the cut-off machine
from a cut while the wheel is moving. If restart-
ing or correcting direction in mid-cut, allow the
wheelto coast to a stop, back the cut-offmachine
up a few inches and center it in the kerf before
restarting.
4. Stay alert. Any distraction can cause twisting
or binding. Repetitive cuts may lull the user into
careless movements.
5. Do not force the tool. Forcingacut-offmachine
reduces control and cutting efficiency.
Ifkickbackshould occur, continue to grip thecut-off
machine firmly and immediately release trigger.
