GENERAL SAFETY RULES — FOR ALL POWER TOOLS
WARNING
Failure to follow all instructions listed below may result in electric shock, fi re and/or
serious injury. The term "power tool" in all of the warnings listed below refers to your
mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
READ ALL INSTRUCTIONS
WORK AREA SAFETY
1. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
2. Do not operate power tools in ex-
plosive atmospheres, such as in the
presence of fl ammable liquids, gases,
or dust. Power tools create sparks which
may ignite the dust or fumes.
3. Keep children and bystanders away
while operating a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
4. 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.
Unmodifi ed plugs and matching outlets
will reduce risk of electric shock.
5. Avoid body contact with earthed or
grounded surfaces such as pipes,
radiators, ranges and refrigerators.
There is an increased risk of electric shock
if your body is earthed or grounded.
6. Do not expose power tools to rain or
wet conditions. Water entering a power
tool will increase the risk of electric
shock.
7. 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.
8. When operating a power tool out-
doors, use an extension cord suitable
for outdoor use. Use of a cord suitable
for outdoor use reduces the risk of electric shock.
PERSONAL SAFETY
9. Stay alert, watch what you are do-
ing and use common sense when
operating a power tool. Do not use
a power tool while you are tired or
under the infl uence of drugs, alcohol
or medication. A moment of inattention
while operating power tools may result
in serious personal injury.
10. Use safety equipment. Always wear
eye protection. Safety equipment such
as dust mask, non-skid safety shoes,
hard hat, or hearing protection used
for appropriate conditions will reduce
personal injuries.
11. Avoid accidental starting. Ensure the
switch is in the off-position before plugging in. Carrying tools with your fi nger on
the switch or plugging in power tools that
have the switch on invites accidents.
12. Remove any adjusting key or wrench
before turning the power tool on. A
wrench or a key left attached to a rotating part of the power tool may result in
personal injury.
13. Do not overreach. Keep proper foot-
ing and balance at all times. This
enables better control of the power tool
in unexpected situations.
14. Dress properly. Do not wear loose
clothing or jewellery. Keep your hair,
clothing and gloves away from moving
parts. Loose clothes, jewellery, or long
hair can be caught in moving parts.
15. If devices are provided for the connec-
tion of dust extraction and collection
facilities, ensure these are connected
and properly used. Use of these de-
vices can reduce dust-related hazards.

POWER TOOL USE AND CARE
SPECIFIC SAFETY RULES
FUNCTIONAL DESCRIPTION
16. 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.
17. Do not use the power tool if the switch
does not turn it on and off. Any power tool
that cannot be controlled with the switch is
dangerous and must be repaired.
18. 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 preven-
tive safety measures reduce the risk of
starting the tool accidentally.
19. Store idle power tools out of the reach
of children and do not allow persons
unfamiliar with the power tools or
these instructions to operate power
tools. Power tools are dangerous in the
hands of untrained users.
20. Maintain power tools. Check for
misalignment or binding of moving
parts, breakage of parts and any
other condition that may affect the
power tool's operation. If damaged,
have the power tool repaired before
use. Many accidents are caused by
poorly maintained power tools.
21. Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to
bind and are easier to control.
22. Use the power tool, accessories and
tool bits etc., in accordance with
these instructions and in the manner
intended for the particular type of
power tool, taking into account the
working conditions and the work to
be performed. Use of the power tool for
operations different from those intended
could result in a hazardous situation.
SERVICE
23. Have your power tool serviced by a
qualifi ed repair person using only
identical replacement parts. This will
ensure that the safety of the power tool
is maintained.
1. Hold power tools by insulated grip-
ping 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.
2. Wear ear protectors. Exposure to noise
can cause hearing loss.
3. Use auxiliary handles supplied with
the tool. Loss of control can cause
personal injury.
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 chemicallytreated 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
fi lter out microscopic particles.

GROUNDING
EXTENSION CORDS
WARNING
Improperly connecting the grounding
wire can result in the risk of electric
shock. Check with a qualifi ed electri-
cian 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 fi t the outlet,
have a proper outlet installed by a
qualifi ed 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.
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 suffi x
“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
qualifi ed person before using it.
• Protect your extension cords from sharp
objects, excessive heat and
damp or wet areas.

Drilling Depth
Installing Drill Bits and Chisels
NOTE: Only use accessories with SDS or
SDS Plus shanks.
Be sure that the shank of the bit is clean.
Dirt particles may cause the bit to line up
improperly. Do not use bits larger than the
maximum recommended capacity of the drill
because gear damage or motor overloading
may result. For best performance, be sure
that the bit is properly sharpened and the
shank is lightly greased before use.
1. Insert the bit or chisel into the nose of
the tool.
2. Rotate bit slowly until it aligns with the
locking mechanism.
3. Push bit into tool until it locks.
4. Check that the bit is locked properly; it
should be possible to pull the bit back
and forth slightly (about 1/4”).
5. To remove bits and chisels, pull bit
holder release collar toward the rear of
tool and remove bit.
NOTE: Use caution when handling hot
bits and chisels.

MILWAUKEE Rotary Hammers have three
settings: drill only, rotary hammer, and hammer only.
Fig. 3
1. For drilling, turn the selector lever so the
arrow on the lever points to the twist drill
symbol .
2. For rotary hammering, turn the selector
lever so the arrow points to the hammer
and twist drill symbol .
3. For hammering only, turn the selector
lever so the arrow points to the hammer
symbol .
4. To freely rotate the bit to the desired
angle for chiseling only, turn the selector
lever so the arrow points to the symbol
. Then, follow step 3.
O
Using the Control Switch
The control switch may be set to three
positions: forward, reverse and lock. Due
to a lockout mechanism, the control switch
can only be adjusted when the trigger is not
pulled. Always allow the motor to come to
a complete stop before using the control
switch.

For forward (clockwise) rotation, push the
control switch to the left side of the tool.
Check the direction of rotation before use.
For reverse (counterclockwise) rotation,
push the control switch to the right side of the
tool. Check direction of rotation before use.
Starting, Stopping and Controlling Speed
1. To start the tool, grasp the handle fi rmly
and pull the trigger.
2. To vary the speed, increase or decrease
the pressure on the trigger. The further
the trigger is pulled, the greater the
speed.
3. To stop the tool, release the trigger.
Make sure the tool comes to a complete
stop before laying the tool down.

Operating
Position the tool, grasp the handles fi rmly
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 fl utes and tend to make the
bit bind in the hole. If the bit should bind, a
built-in, non-adjustable slip clutch prevents
the bit from turning. If this occurs, stop the
tool, free the bit and begin again.
Using Core Bits
Core bits are useful for drilling large holes for
conduit and pipe. MILWAUKEE Heavy-Duty
Thin Wall Core Bits have heat treated steel
bodies with durable carbide tips. They are
specially designed for fast, accurate drilling with combined hammering and rotary
action.
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 a ssembly 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 fi rmly against your
center mark, hold the tool fi rmly 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 fi nished 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.
MILWAUKEE Heavy-Duty Thin Wall Core
Bits drill holes up to 3" deep. T o make deeper
holes, remove the bit, break and remove the
core. Resume drilling.

APPLICATIONS
Drilling in Wood, Composition Materials
and Plastic
When drilling in wood, composition materials
and plastic, select the drill operating mode.
Start the drill slowly, gradually increasing
speed as you drill. Select low speeds for
plastics with a low melting point.
Drilling in Metal
When drilling in metal, select the drill operating mode. Use high speed steel twist drills
or hole saws. Use a center punch to start
the hole. Lubricate drill bits with cutting oil
when drilling in iron or steel. Use a coolant
when drilling in nonferrous metals such as
copper, brass or aluminum. Back the material to prevent binding and distortion on
breakthrough.
Drilling in Masonry
When drilling in masonry, select the rotary
hammer operating mode. Use high speed
carbide-tipped bits. Drilling soft masonry
materials such as cinder block requires
little pressure. Hard materials like concrete
require more pressure. A smooth, even fl ow
of dust indicates the proper drilling rate. Do
not let the bit spin in the hole without cutting. Do not use water to settle dust or to
cool bit. Do not attempt to drill through steel
reinforcing rods. Both actions will damage
the carbide.
