GENERAL SAFETY RULES
4. Grounded tools must be plugged into an outlet properly
installed and grounded in accordance with all codes and
ordinances. Never remove the grounding prong or modify
the plug in any way. Do not use any adaptor plugs. Check
with a qualified electrician if you are in doubt as to whether
the outlet is properly grounded. If the tools should electrically
malfunction or break down, grounding provides a low resistance
path to carry electricity away from the user.
5. Double Insulated tools are equipped with a polarized plug
(one blade is wider than the other). This plug will fit in a
polarized outlet only one way. If the plug does not fit fully in
the outlet, reverse the plug. If it still does not fit, contact a
qualified electrician to install a polarized outlet. Do not change
the plug in any way. Double insulation eliminates the need for
the three wire grounded power cord and grounded power supply
system.
6. Avoid body contact with grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased risk
of electric shock if your body is grounded.
7. Do not expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
8. Do not abuse the cord. Never use the cord to carry the tools
or pull the plug from an outlet. Keep cord away from heat,
oil, sharp edges or moving parts. Replace damaged cords
immediately. Damaged cords increase the risk of electric shock.
9. When operating a power tool outside, use an outdoor
extension cord marked W-A or W. These cords are rated
for outdoor use and reduce the risk of electric shock.
10. Stay alert, watch what you are doing, and use common sense
when operating a power tool. Do not use tool while tired or
under the influence of drugs, alcohol, or medication. A
moment of inattention while operating power tools may result in
serious personal injury.
11. Dress properly. Do not wear loose clothing or jewelry.
Contain long hair. Keep your hair, clothing, and gloves away
from moving parts. Loose clothes, jewelry, or long hair can be
caught in moving parts.
12. Avoid accidental starting. Be sure switch is off before
plugging in. Carrying tools with your finger on the switch or
plugging in tools with the switch on invites accidents.
13. Remove adjusting keys or wrenches before turning on the
tool. A wrench or a key that is left attached to a rotating part of the
tool may result in personal injury.
14. Do not overreach. Keep proper footing and balance at all
times. Proper footing and balance enables better control of the tool
in unexpected situations.
15. Use safety equipment. Always wear eye protection. Dust
mask, non-skid safety shoes, hard hat, or hearing protection must
be used for appropriate conditions.
16. Use clamps or other practical way to secure and support
the workpiece to a stable platform. Holding the work by hand
or against your body is unstable and may lead to loss of control.
17. Do not force tool. Use the correct tool for your application.
The correct tool will do the job better and safer at the rate for which
it is designed.
18. Do not use tool if switch does not turn it on or off. Any tool
that cannot be controlled with the switch is dangerous and must be
repaired.
19. Disconnect the plug from the power source before making
any adjustments, changing accessories, or storing the tool.
Such preventive safety measures reduce the risk of starting the tool
accidentally.
20. Store idle tools out of reach of children and other untrained
persons. Tools are dangerous in the hands of untrained users.
21. Maintain tools with care. Keep cutting tools sharp and clean.
Properly maintained tools with sharp cutting edge are less likely to
bind and are easier to control. Do not use a damaged tool. Tag
damaged tools Do not use until repaired.
22. Check for misalignment or binding of moving parts, break-
age of parts, and any other condition that may affect the
tools operation. If damaged, have the tool serviced before
using. Many accidents are caused by poorly maintained tools.
23. Use only accessories that are recommended by the manu-
facturer for your model. Accessories that may be suitable for
one tool, may become hazardous when used on another tool.
24. Tool service must be performed only by qualified repair
personnel. Service or maintenance performed by unqualified per-
sonnel could result in a risk of injury.
25. When servicing a tool, use only identical replacement parts.
Follow instructions in the Maintenance section of this
manual. Use of unauthorized parts or failure to follow Maintenance
Instructions may create a risk of electric shock or injury.
1. Keep your work area clean and well lit. Cluttered benches and
dark areas invite accidents.
2. Do not operate power tools in explosive atmospheres, such
as in the presence of flammable liquids, gases, or dust.
Power tools create sparks which may ignite the dust or fumes.
3. Keep bystanders, children, and visitors away while operat-
ing a power tool. Distractions can cause you to lose control.
Protect others in the work area from debris such as chips and
sparks. Provide barriers or shields as needed.

SPECIFIC SAFETY RULES SANDERS AND GRINDERS
1. Always use proper guard with grinding wheel. A guard protects operator from broken wheel fragments.
2. Accessories must be rated for at least the speed recommended on the tool warning label. Wheels and other accessories running
over rated speed can fly apart and cause injury.
3. Hold 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 make exposed metal parts of the tool live and shock the operator.
4. Keep hands away from all cutting edges and moving parts.
5. Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a free
replacement.
6. 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, 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 filter out microscopic
particles.

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 exten-
sion 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 mini-
mum wire size.
Guidelines for Using Extension Cords
If you are using an extension cord outdoors, be sure it is marked
with the suffix 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 qualified person before using it.
Protect your extension cords from sharp objects, excessive heat
and damp or wet areas.
GROUNDING EXTENSION CORDS
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 re-
sistance path to carry electricity
away from the user, reducing the risk
of electric shock.
Improperly connecting the grounding wire can
result in the risk of electric 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.

READ AND SAVE ALL INSTRUCTIONS
FOR FUTURE USE.
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 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 complies with the applicable
standards of Underwriters Labora-
tories, Inc., the Canadian Standard
Association and the National Electri-
cal Code. Double Insulated tools may
be used in either of the 120 volt out-
lets shown in Figures B and C.

Sanding (Fig. 4)
1. Use a clamp, vise or other practical means to hold your work, free-
ing both hands to control your tool. Firmly grasp body of tool and
side handle before starting and while tool is in operation. Allow
sanding disc to come to full speed before beginning to sand.
2. Hold sander/grinder at to 15° angle (Fig. 4) to ensure proper
sanding pressure and control. Too great an angle will result in too
much pressure and could cause excessive wear to the disc and
workpiece. Too small an angle will reduce control.
3. Use long, sweeping, side to side strokes, advancing forward to
produce the desired finish.
Removing Welds or Hammer Marks
When removing welds or hammer marks, limit coarse sanding to the
immediate area. Use successively finer grits to smooth surface.
Cross Sanding
When finishing a surface that has been prepared by a coarse disc or
wheel, sand at right angles to the strokes made by the coarser disc.
Finishing marks left from previous sanding are easily seen and removed
for a uniform finish. Failure to cross sand when changing from a coarse
disc to a finishing disc may result in deep scratches and circular marks.
Finishing Metal
Constantly move across the surface. Work faster on curved surfaces
where contact areas are smaller and pressure is greater. Flat areas may
appear at the end of the stroke when pressure is too heavy. Ease up on
pressure at end of each stroke and when reversing strokes.
Troubleshooting
Deep scratches and circular marks can result from:
Using too coarse a grit
Using a partially glazed disc
Dirt or loose metal on the workpiece
Failure to sand across the grain when changing from coarse to
finishing discs
Failure to use closed coated discs to reduce the problem
of grains working loose and scratching the workpiece
Bluish discoloration of metal surface indicates:
Excessive heat caused by circular motion in a small area
Excessive pressure
Use of worn out or glazed discs

Sanding Disc and Grinding Wheel Material
Sanding discs and grinding wheels are made of various materials and
are designed for different jobs. Be sure that you choose the proper
sanding disc or grinding wheel for the job you plan to do.
Selecting Sanding Discs & Grit
Refer to the table below to select the correct type of sanding disc for
your job. Generally, use 24 or 36 grit for heavy stock removal; 50, 60, or
80 grit for medium stock removal and 120 grit for finishing. Always begin
with a coarse grit, using successively finer grits to obtain the desired
finish. See your MILWAUKEE Electric Tool Catalog for a complete list of
sanding discs.

WARNING!
Care of Grinding & Cut-Off Wheels
Grinding and cut-off wheels should be protected from:
wetness and extreme humidity
any type of solvent
extreme changes in temperature
dropping and bumping
Grinding and cut-off wheels should be stored:
in an organized way so wheels can be removed without disturbing
or damaging other wheels
with their safety information
Grinding and cut-off wheels should NOT be:
dropped
rolled
bumped
If any wheel is dropped, rolled, bumped, subjected to extreme changes
in temperature, or has come into contact with solvents or wetness,
discard wheel immediately.
Only use wheels with Maximum Safe
Operating Speed rated at or above the RPM
listed on the WARNING section of the
tool's nameplate. This speed is based on
the strength of the wheel, allowing for a
reasonable measure of safety. It is not
meant to imply a best or most efficient
operating speed. Do not exceed the
Maximum Safe Operating Speed.
WARNING!
Always handle wheels carefully to avoid damage. Before installing any
wheel, always inspect it for cracks. If wheel is cracked, discard it to
prevent others from using it.
WARNING!
To reduce the risk of injury when grinding:
ALWAYS use the proper guard.
ALWAYS properly install the guard.
ALWAYS hold the tool firmly with both hands
using the handles provided before and during
grinding.
NEVER use a wheel that has been dropped.
NEVER bang grinding disc onto work.
NEVER grind without proper safety equipment.
Grinding and Cut-off Wheels
page 8
Selecting Wheels
Grinding is the cutting action of thousands of abrasive grains on the face
of a grinding wheel. When grinding metals such as steel and iron, choose
an aluminum oxide grinding wheel. Select a silicon carbide grinding wheel
for stone and concrete. Use cotton reinforced wheels for non-ferrous
metals.
Type 27 Reinforced 1/8" Cut-Off Wheels are suited for small cut-off and
shallow notching operations only.
Installing Grinding Wheels (Fig. 8, 9, & 10)
1. When guard is properly positioned, place flange on spindle with
flange facing away from tool.
2. Place selected wheel on spindle and align with flange. Position flange
nut according to wheel thickness (Fig. 8 & 9).
3. Press the spindle lock button while turning flange nut clockwise.
Tighten securely with the spanner wrench provided.
4. To remove wheel, unplug tool and reverse procedure.
To reduce the risk of injury, do not use the
spindle lock button to stop the spindle while the
tool is in use or is coasting after shut-off. This will
result in tool damage.
WARNING!
Grinding (Fig. 11)
1. If you have just installed a grinding wheel or are just beginning a
period of work, test wheel by letting it spin for one minute before
applying it to the workpiece.
NOTE: Out-of-balance wheels can mar workpiece, damage the tool,
and cause stress to wheel that may cause wheel failure.
2. Firmly grasp body of tool and side handle before starting and while
using tool. Allow wheel to come to full speed before starting to grind.
3. When grinding, hold sander/grinder at a 5
o
to 15
o
angle, using con-
stant pressure for a uniform finish. Too great an angle causes con-
centrated pressure on small areas which may gouge or burn work
surface.
4. Control pressure and surface contact between disc and workpiece.
Too much pressure slows cutting speed.

Using Cut-Off Wheels (Fig. 12)
Type 1 Cut-Off Wheels are suited for small cut-off and shallow notch-
ing operations only.
1. Firmly grasp body of tool and side handle before starting and while
using tool. Allow wheel to come to full speed before starting.
2. When using a cut-off wheel, hold Sander/Grinder as shown, using
only the edge of the wheel.
A Type 1 guard must be installed when using
a cut-off wheel to provide maximum protection
for the operator if the wheel should break.
WARNING!
Fig. 12
3. Control pressure and surface contact between disc and workpiece.
Too much pressure slows cutting speed.
Using the face of a Cut-Off Wheel (as in grinding)
will cause the Wheel to crack and break, resulting
in serious personal injury.
WARNING!
Everyone in the area must wear protective clothing
and safety goggles or face shields. Fatigued wires
and residue will fly off the brush with considerable
force, causing potential for serious injury.
WARNING!
Installing Wire Cup Brushes (Fig. 13)
2. To install, thread wire cup brush onto spindle. Press the spindle lock
button while tightening brush with a 7/8" open end wrench (not
provided with tool).
3. To remove wire cup brush, unplug tool and reverse procedure.
Using Wire Wheel Brushes (Fig. 14)
WARNING!
Because the wires on wire wheel brushes are
directed towards the operator, a guard must be
used to protect the operator when fatigued wires
break.
WARNING!
Never exceed Maximum Safe Operating Speed of
brush. Do not use a damaged brush or one which
is functioning improperly (throwing wires, out-
of balance, etc.). these conditions increase the
possibility of further brush failure and possible
injury. Discard and replace damaged brushes
immediately.
1. Unplug tool and place it upside down on a level surface as shown.
Remove any accessories from spindle.
Fig. 13
Wire Cup Brush
Wire Wheel Brush
Fig. 14
Guard
Wire wheel brushes are useful for removing rust, scale, burrs, weld
slag, etc. A wide variety of wire brushes are available for many
applications.
Test wire wheel brush for balance and loose or damaged wires by
running tool at no load speed for at least one minute before applying it to
your work. During this time, no one should stand in front of or in line with
it. When applying brush to work, avoid using too much pressure. This
causes over-bending of wires and heat build-up resulting in premature
wire breakage, rapid dulling and reduced brush life. Instead of using
more pressure, try a wire wheel brush with more aggressive cutting
action (increased wire size, decreased wire length or different brush
type, i.e. knot type instead of crimped wire type).
page 10
Maintaining Tools
Keep your tool in good repair by adopting a regular maintenance pro-
gram. 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 mount-
ing, broken parts and any other condition that may affect its safe opera-
tion. If abnormal noise or vibration occurs, turn the tool off immediately
and have the problem corrected before further use. Do not use a dam-
aged 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:

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 flammable or
combustible solvents around tools.
