GENERAL POWER TOOL SAFETY WARNINGS
WARNING READ ALL SAFETY WARNINGS AND ALL INSTRUCTIONS. Failure to
follow the warnings and instructions may result in electric shock, fi re and/or serious injury. Save
all warnings and instructions for future reference. The term “power tool” in the warn-
ings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
• Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of fl ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
• Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
ELECTRICAL SAFETY
WORK AREA SAFETY
• 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.
• 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.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase
the risk of electric shock.
• 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.
• When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use
of a cord suitable for outdoor use reduces the risk
of electric shock.
• If operating a power tool in a damp location is
unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of an GFCI
reduces the risk of electric shock.
PERSONAL SAFETY
• Stay alert, watch what you are doing 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 medi-
cation. A moment of inattention while operating
power tools may result in serious personal injury.
• Use personal protective equipment. Always
wear eye protection. Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions
will reduce personal injuries.
• Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools with
your fi nger on the switch or energising power tools
that have the switch on invites accidents.
• 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.
• Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.
• If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
POWER TOOL USE AND CARE
• 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.
• 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.
• 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 pre-
ventive safety measures reduce the risk of starting
the power tool accidentally.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar with
the power tool or these instructions to operate
the power tool. Power tools are dangerous in the
hands of untrained users.
• 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.
• Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits
etc. in accordance with these instructions, 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
• 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.
SPECIFIC SAFETY RULES
• Wear ear protectors. Exposure to noise can
cause hearing loss.
2
• Use auxiliary handle(s), if supplied with the
tool. Loss of control can cause personal injury.
• Hold power tools by insulated gripping surfaces,
when performing an operation where the cutting
tool may contact hidden wiring or its own cord.
Cutting accessory contacting a “live” wire may make
exposed metal parts of the power tool “live” and
could give the operator an electric shock.
• Keep hands away from all cutting edges and
moving parts.
• Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.
GROUNDING
WARNING Improperly connecting the
grounding wire can result in the risk of electric shock. Check with a qualifi ed 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
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.
Y our 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 satisfi es OSHA requirements and com-
plies 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.

Fig. C
• 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 fi lter out microscopic particles.
EXTENSION CORDS
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 Cana-
da) 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.

Selecting Action
MILWAUKEE Rotary Hammers have three settings:
rotation only, rotary hammer, and hammer only.
Always allow the motor to come to a complete
stop before changing the mode selection to avoid
damage to the tool.
1. For rotation only, 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
hammering only, turn the selector lever to the
symbol. Then, follow step 3.
NOTE: To engage the hammering mechanism,
maintain pressure on the bit. When pressure on
the bit is released, the hammering action will stop.
Starting and Stopping
1. To start the tool, grasp the handle fi rmly and pull
the trigger.
2. To stop the tool, release the trigger. Make sure
the tool comes to a complete stop before laying
the tool down.
Using the Control Switch
Always allow the motor to come to a complete stop
before using the control switch to avoid damage
to the tool.
For forward (clockwise) rotation, push in the control
switch from the right side of the tool. Check the
direction of rotation before use.
For reverse (counterclockwise) rotation, push in the
control switch from the left side of the tool. Check
direction of rotation before use.
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.
Cold Starting
If this tool is stored for a long period of time or
at cold temperatures, it may not hammer initially because the lubrication has become stiff.
To warm up the tool:
1. Insert and lock a bit or chisel into the tool.
2. Pull the trigger and apply force to the bit or chisel
against a concrete or wood surface for a few
seconds. Release the trigger
3. Repeat until the tool starts hammering. The colder the tool is, the longer it will take to warm up.
Using Rotary Percussion Core Bits
Core Bits are useful for drilling large or long holes
in concrete. MILWAUKEE Heavy-Duty Core Bits
have heat-treated steel bodies with durable carbide
tips. These core bits 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 to make later removal easier. Thread
the adapter shank to the rear of the core bit.
2. Push the guide plate
onto the pointed end
of the center pin. Insert the center pin and
guide plate assembly
into the core bit. Be
sure the small end of
the center pin is securely placed into the
hole in the center of the
core bit.
For LHS systems,
screw the threaded
end of the centering bit
into the core bit.
NOTE: If using an ex-
tension, fi rst thread the
adapter shank to the
extension. Then thread the core bit to the extension.
3. Insert the adapter into the nose of the tool as
described in “Installing Bits and Chisels”. Set the
knob to the "hammering
with rotation" setting.
4. Press the centering
bit fi rmly against your
center mark, hold the
tool fi rmly and pull the
trigger.
5
NOTE: If the 48-20-
5099 threaded stud is
used, or a center pin
and guide plate are
not available, use a
template or notched
board to start the hole.
5. Start the tool. After drilling to about the depth
of the core bit teeth,
remove the center pin
and guide plate from
the core bit (not necesary for LHS system). Resume drilling.
6. To change the core bit, hold the tool upwards,
pointing it away from your body, and run it briefl y
in forward to loosen the core bit from the adapter.
NOTE: T o make deeper holes, remove the core bit,
break and remove the core, then resume drilling.
When drilling long or deep holes, after each inch
of penetration pull the bit partially out of the hole
while the tool is running, to help clear dust from the
bit fl utes. Dust can clog the bit fl utes and can make
the bit bind in the hole. If this occurs, stop the tool,
free the bit and begin again.
Drilling Large Diameter Holes with Core Bits
When drilling holes with large diameter core bits,
dust may build up in the cut and can cause the tool
to stall, bind, or cut slowly. By creating an opening
for the dust to escape, drilling time, bit stress, and
tool stress can be reduced.
1. Start the cut as normal.
2. Once the bit is fi rmly estab-
lished in the cut (about 1/4"
deep), remove the bit from the
cut.
3. Remove the bit from the tool.

the core must be
broken and removed.
• Install a chisel bit.
• Place the chisel into
the hole kerf.
• Chisel down into
the kerf at several
points until the core is loose or broken.
• Remove the core and vacuum/remove any
remaining dust and debris.
• Install the core bit and continue the cut.
Chiseling and Chipping
MILWAUKEE Rotary Hammers may be used for
chipping and chiseling.
When chiseling, hold the tool at an angle to the
workpiece. Work from a corner or close to the edge
of the workpiece, breaking off one small area at a
time rather than attempting too large an area.
A variety of accessories are available.
Bushing Tools
Used to surface concrete.
Mortar Cutting Chisels
(Seam Tools)
For removing old mortar for tuck
pointing or caulking.
Bull Points
For demolition work and starting
holes in concrete slabs.
Flat Chisels
For edging, chipping or channeling.
Scaling Chisels
For removing weld spatter or scale
and cutting straight lines.
Slotting Chisel
For slotting and cutting between
drilled holes in concrete and masonry.
