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

Installing Backing Pad and Sanding Discs (Fig. 3)

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 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

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:

 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

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.

MAINTENANCE
