GENERAL POWER TOOL
SAFETY WARNINGS
WARNING
Read all safety warnings, instructions, illustrations and specica-
tions provided with this power tool. Failure to
follow all instructions listed below may result in
electric shock, re and/or serious injury. Save all
warnings and instructions for future reference.
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-oper-
ated (cordless) power tool.
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
• Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
• Keep children and bystanders away while operat-
ing a power tool. Distractions can cause you to lose
control.
ELECTRICAL 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. Unmodied 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 inuence of drugs, alcohol or medication. 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 a 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 nger on the
switch or energizing 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 bal-
ance at all times. This enables better control of the
power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewelry. Keep your hair and clothing away from
moving parts. Loose clothes, jewelry 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.
• Do not let familiarity gained from frequent use
of tools allow you to become complacent and
ignore tool safety principles. A careless action
can cause severe injury within a fraction of a second.
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 remove the battery pack, if detachable, from
the power tool before making any adjustments,
changing accessories, or storing power tools.
Such preventive 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 and accessories. 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 hazard-
ous situation.
• Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles
and grasping surfaces do not allow for safe handling
and control of the tool in unexpected situations.
BATTERY TOOL USE AND CARE
• Recharge only with the charger specied by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of re when used
with another battery pack.
• Use power tools only with specically designated
battery packs. Use of any other battery packs may
create a risk of injury and re.
3
• When battery pack is not in use, keep it away
from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects,
that can make a connection from one terminal to
another. Shorting the battery terminals together may
cause burns or a re.
• Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact accidentally occurs, ush with water. If liquid con-
tacts eyes, additionally seek medical help. Liquid
ejected from the battery may cause irritation or burns.
• Do not use a battery pack or tool that is damaged or modied. Damaged or modied batteries
may exhibit unpredictable behavior resulting in re,
explosion or risk of injury.
• Do not expose a battery pack or tool to re or
excessive temperature. Exposure to re or tem-
perature above 265°F (130°C) may cause explosion.
• Follow all charging instructions and do not
charge the battery pack or tool outside the
temperature range specied in the instructions.
Charging improperly or at temperatures outside the
specied range may damage the battery and increase
the risk of re.
SERVICE
• Have your power tool serviced by a qualied
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
• Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
SPECIFIC SAFETY RULES FOR
ROTARY HAMMERS
• Wear ear protectors. Exposure to noise can cause
hearing loss.
• 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. 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 im-
portant information. If unreadable or missing, contact
a MILWAUKEE service facility for a free replacement.
•
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 lum-
ber.
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
lter out microscopic particles.

Starting and Stopping
1. To start the tool, grasp the handle 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.
Operating
Position the tool, grasp the handles rmly and pull
the trigger. Always hold the tool securely using both
handles to maintain control. This tool has been de-
signed to achieve top performance with only moder-
ate 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 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 ini-
tially 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 cen-
ter of the core bit.
For LHS systems, screw
the threaded end of the
centering bit into the core bit.
NOTE: If using an extension, first 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.

Selecting Action
These MILWAUKEE Rotary Hammers
have three settings: hammering with
rotation, hammering-only, and chisel
adjustment.
1. Hammering with rotation. Use this
setting for drilling holes with drill bits.
2. Hammering only. For use with
“hammering-only” accessories. Use
this setting for chiseling or setting
self-drilling anchors.
3. Chisel adjustment. Use this setting
to adjust the angle of the chisel
blade in relation to the tool. With a
chisel mounted in the tool:
• turn the knob to this setting
• rotate the chisel to the desired
angle
• turn the knob to "hammering-only".
NOTE: To engage the hammering mechanism, main-
tain pressure on the bit. When the pressure on the bit
is released, the hammering will stop.

4. Press the centering bit
rmly against your cen-
ter mark, hold the tool
rmly and pull the trigger.
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 drill-
ing to about the depth
of the core bit teeth,
remove the center pin
and guide plate from
the core bit (not nece-
sary for LHS system).
Resume drilling.
6. To change the core bit, hold the tool upwards,
pointing it away from your body, and run it briey
in forward to loosen the core bit from the adapter.
NOTE: To 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 utes. Dust can clog the bit 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 rmly established in

3. Remove the bit from the tool.
4. Install a standard uted bit, approximately 7/8" in diameter, onto
the tool.
5. Drill a perpendicular hole through
the kerf of the large hole.
• Depending on the location of the
work, the hole should either break
through the other side of the hole/
oor or extend 4"-5" past the end
of the workpiece (such as into the
dirt below a concrete slab).
• If dust builds up in the hole,vacuum
it out and continue drilling.
• If drilling through a wall, the hole
for dust should be drilled on the
Side v ie

in the kerf, pull back on the bit
with the hammer running. This
will remove some of the dust
and debris from the cut. Repeat
this for every inch of drilling. If
necessary, vacuum dust and
debris from the cut and sur-
rounding area.
7. For core bits, once the maximum
core bit depth is drilled, 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.
WARNING
To reduce the risk of personal injury and damage to the tool or work:
• Always use the “hammering-only” setting to
set the anchor. Never use the “hammeringwith-rotation” setting to set the anchor.
• Never switch the tool to “hammering-with-
rotation” until after the anchor has been set
and the tooth anchor chuck has been removed
from the anchor.
Setting Self-Drilling Anchors
MILWAUKEE Tooth Anchor Chucks require a “B”
taper adapter.
1. Place the proper size tooth anchor chuck into the
“B” taper adapter. Then insert the “B” taper adapter
into the tool and lock it into place as described.
See “Installing Bits and Chisels”.
2. Insert the anchor into
1/8"
the tooth anchor chuck.
Set the knob for ham-
mering only. Set the
anchor on your mark
and hammer until the
teeth have penetrated
the concrete.
3. Set the knob for ham-
mering with rotation
and drill until the chuck
is 1/8" above the concrete.
NOTE: It may be nec-
essary to clean dust
and cuttings from the
anchor several times
while drilling the hole.
4. Remove the anchor
from the hole while the
tool is running. Clean
the dust and cuttings
from the anchor by
pointing it downward
and turning the tool on
and off several times. Clean the dust out of the
hole with a vacuum cleaner or blowout bulb.
5. Place the expansion plug into the anchor and insert
the anchor into the hole. Switch the knob back to
hammering only, and hammer the anchor rmly
into the hole.
