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 the
tool on. 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
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 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

1. 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 tool “live” and shock the operator.

2. Wear ear protectors when using the tool for extended periods. Prolonged exposure to high intensity noise can cause hearing loss.

3. Keep hands away from all cutting edges and moving parts.

4. Maintain labels and nameplates. These carry important information. If unreadable or missing, contact 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, 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 specifically 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
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.

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 Labora­tories, Inc., the Canadian Standard
Association and the National Electri­cal Code. Double Insulated tools may
be used in either of the 120 volt out­lets shown in Figures B and C.

MILWAUKEE

Fig. A

Fig. B

Fig. C

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.

Starting, Stopping & Controlling Speed

1. To start the tool, pull trigger.

2. To stop the tool, release trigger.

3. To vary the speed, increase or decrease pressure applied to trigger.

Operating

Position the tool, grasp the handles firmly and pull the trigger. Always
hold the tool securely using both handles to maintain control. This tool
has been designed to achieve top performance with only moderate
pressure. Let the tool do the work.

If the speed begins to drop off when drilling large or deep holes, pull the
bit partially out of the hole while the tool is running to help clear dust. Do
not use water to settle the dust since it will clog the bit flutes and tend to
make the bit bind in the hole. If the bit should bind, a built-in, non­adjustable slip clutch prevents the bit from turning. If this occurs, stop
the tool, free the bit and begin again.

Guide Plate

1. Clean and lubricate the threads on the adapter and core bit as
indicated (Fig. 5) to make later removal easier. Screw the threaded
end of the adapter into the rear of the core bit.

2. Push the guide plate onto the pointed end of the center pin. Insert the
center pin with guide plate assembly into to the core bit. Be sure the
small end of the center pin is securely placed into the hole in the
center of the adapter.

3. Insert the adapter into the bit holder of the tool as described in
“Inserting Drill Bit or Chisel”. Set the rotary hammer/drill lever to
rotary hammer.

4. Press the center pin firmly against your center mark, hold the tool
firmly and pull the trigger.

5. After drilling to about the depth of the core bit teeth, remove the
center pin and guide plate from the core bit. Resume drilling.

6. After you have finished drilling the hole, hold the tool upwards,
pointing it away from your body, and run it briefly in forward to
loosen the core bit from the adapter.
