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-opearted (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 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.
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 outdoors, use an extension cord suit-
able 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 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 medication. A moment
of inattention while operating power tools may result in serious personal
injury.
10. Use safety equipment. Always wear eye protection. Safety equip-
ment 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 footing 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 connection of dust extraction and
collection facilities, ensure these are connected and properly used.
Use of these devices can reduce dust-related hazards.
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 preventive safety measures
reduce the risk of starting the tool accidentally.
19. Store idle power tools out of the reach of children and do not al-
low 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.
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.
POWER TOOL USE AND CARE
SERVICE
page 2
SPECIFIC SAFETY RULES
1. Hold power tools 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.
2. Wear ear protectors. Exposure to noise can cause hearing loss.
3. Keep hands away from all cutting edges and moving parts.
4. Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.
5. Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a free re-
placement.
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 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 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 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.
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
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.
Fig. A
Fig. B
Fig. C
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.

These rotary hammers have an Electronic Feedback Control Circuit (EFCC)
which helps improve the operation and life of the tool.
Soft Start
The Soft-Start feature reduces the amount of torque reaction to the tool and
the user. This feature gradually increases the motor speed up from zero to
the speed set by the speed control dial.
Feedback Control
The electronic speed control system allows the tool to maintain constant
speed between no-load and load conditions.
Service Indicator Light
These hammers feature a service indicator light. When the red service light
turns on, the tool is ready for servicing. Return the tool to an authorized
service center.
NOTE: When the service light is on, the tool will continue to run for a few
hours and then the motor will shut off.
Power Indicator Light
When the green power indicator light is on, current is entering the Elec-tronic
Feedback Control Circuit (EFCC) and the tool is ready for operation.

2. Hammering with rotation. Use this setting (2) for drilling holes with
drill bits.
3. Chisel adjustment. (Cat. No. 5315-21 only) Use this setting (3) 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
• twist the chisel to the desired angle
• set the tool for hammering only
NOTE: T o engage the hammering mechanism, maintain pressure on the bit.
When the pressure on the bit is released, the hammering will stop.
WARNING
To reduce the risk of injury, when using chisels or (other hammering-only accessories) in
the 5315-21 Rotary Hammer, set the tool in the
“hammering-only” position.
Hammering Only
SDS Max Drive System (Cat. No. 5315-21)
When using chisels (or other “hammering-only” accessories) in
the 5315-21 Rotary Hammer, the stop rotation knob MUST be set in
the“hammer-only” setting. The rotational drive mechanism in the
5315-21 engages with the chisel (or other “hammering-only” accessory) then it is mounted into the tool and the stop rotation knob is set for
“hammering-with-rotation”.
Hammering Only
Spline Drive System (Cat. No. 5319-21 & 5321-21)
When a chisel (or other “hammering-only” accessory) is mounted into the
5319-21 or 5321-21 Rotary Hammer, the rotational drive mechanism does
not engage with the chisel. The 5321-21 can use chisels in the “hammering-with-rotation” setting or the “hammering-only” setting.
NOTE: The 5321-21 Rotary Hammer must be set in the “hammeringonly” setting when setting self-drilling anchors. See “Setting Self-Drilling
Anchors" for complete instructions.
Selecting Speed
These rotary hammers have a speed control dial. The speed control dial
allows the user to adjust the rotating speed (RPM) and the impact rate
(BPM) of the tool.
To change the speed, set the speed control dial to the desired setting.
Lower speeds provide more control when starting holes and reduce ‘spalling’
on breakthrough. Spalling occurs when pieces of material chip off around the
drilled hole on breakthrough. When chiseling in soft or brittle materials, use
lower speeds to reduce damage to surrounding areas of the material.
Higher speeds provide for faster penetration when drilling and chiseling in
demolition work.
Starting and Stopping the Tool
1. To start the tool, pull trigger.
2. To stop the tool, release trigger.
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. Turn the tool on, applying force to the bit or chisel against a concrete
or wood surface.
3. Turn the tool on and off every few seconds. In a short time, the tool will
start hammering. The colder the tool is, the longer it will take to warm
it up.
WARNING
Applying greater pressure does not increase the
tool's effectiveness. If the applied working pressure is too high, the shock absorber will be pushed
together making the vibrations to the handle noticeably stronger.
Operator Force (Fig. 7)
These rotary hammers feature the Vibration Isolation System to provide the operator with comfort without sacrificing power or performance. The motor is suspended independently from the switch handle.
Insulating elements absorb up to 50% of the vibration when hammering
and drilling.
Ideal operator force compresses the bellows slightly and allows the tool to
work aggressively while the handle remains steady.
Excessive force compresses the bellows signifi cantly and reduces vibration
dampening. Users will be able to feel the difference and should adjust the
force to the handle accordingly (Fig. 7).
Fig. 7
Using Rotary Percussion Core Bits (Fig. 8-11)
Core bits are useful for drilling large holes for conduit and pipe.
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. 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 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 (Fig. 8).
Fig. 8
3. Insert the adapter into the nose of the tool as described in “Installing Bits”. Set the stop rotation knob to the hammering-with-rotation
setting.
4. Press the center pin fi rmly against your center mark, hold the tool fi rmly
and pull the trigger (Fig. 9).
Fig. 9
ideal applied force
The side handle works in a similar fashion, where moderate operator force
dampens vibration and excessive force reduces this effect.
Hammering or Hammering with Rotation
Position the tool, grasp the handles fi rmly and pull the trigger.
Always hold the tool securely using both handles and maintain control. Use
only enough pressure to hold the tool in place and prevent the tip of the bit
from wandering. This tool has been designed to achieve top performance
with only moderate pressure. Let the tool do the work.
When drilling deep holes occasionally pull the bit partially out of the hole
while the tool is running to help clear dust.
NOTE: 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.
excessive applied force
NOTE: If a center pin and guide plate are not available, use a template
or notched board to start the hole (Fig. 10).
Fig. 10
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.
page 7
6. To change the core bit, hold the tool upwards, pointing it away from
your body as shown, and run it briefl y in forward to loosen the core bit
from the adapter (Fig. 11).
Fig. 11
NOTE: If the 48-20-5099 threaded stud is used, use a template or
notched board to start the hole (Fig. 14).
Fig. 14
NOTE: To make deeper holes, remove the core bit, break and remove
the core. Resume drilling.
Using LHS Rotary Percussion Core Bits (Fig. 12-15)
LHS 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. Screw the threaded end of the centering bit into
the core bit (Fig. 12). Thread the adapter shank to the rear of the core
bit.
NOTE: If using an extension, fi rst thread the adapter shank to the
extension. Then thread the core bit to the extension.
Fig. 12
2. Insert the adapter into the nose of the tool as described in “Installing Bits”. Set the stop rotation knob to the hammering-with-rotation
setting.
3. Press the centering bit fi rmly against your center mark, hold the tool
fi rmly and pull the trigger (Fig. 13).
4. To change the core bit, hold the tool upwards, pointing it away from
your body as shown, and run it briefl y in forward to loosen the core bit
from the adapter (Fig. 15).
Fig. 15
NOTE: To make deeper holes, remove the core bit, break and remove the
core. 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.
