GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS.
Failure to follow all instructions listed below, may result in
electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS.
WORK AREA
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.
ELECTRICAL SAFETY
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.
PERSONAL SAFETY
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.
TOOL USE AND CARE
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
tools 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 manufacturer for your model. Accessories that may be suitable for
one tool, may become hazardous when used on another tool.
SERVICE
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.
page 2
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.

GROUNDING EXTENSION CORDS
WARNING!
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.
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 appropriate outlet, properly installed
and grounded in accordance with all codes and ordinances. The plug
and outlet should look like those in Figure A.
Fig. A
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 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.

the proper accessory for the job.
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.

For best result use
only this portion of disc
1. Use a clamp, vise or other practical means to hold your work, freeing 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 5° 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

Grinding and Cut-off Wheels
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.

Using Wire Wheel Brushes (Fig. 14)
Fig. 14
Wire Wheel Brush
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).
WARNING!
Never exceed Maximum Safe Operating Speed of
brush. Do not use a damaged brush or one which
is functioning improperly (throwing wires, outof balance, etc.). these conditions increase the
possibility of further brush failure and possible
injury. Discard and replace damaged brushes
immediately.

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 flammable or
combustible solvents around tools.
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 flow inside the tool.
Repairs
If your tool is damaged, return the entire tool to the nearest service
center listed on the back cover of this operators manual.
