GENERAL SAFETY RULES-FOR ALL BATTERY OPERATED TOOLS
POWER TOOL USE AND CARE
BATTERY TOOL USE AND CARE
WARNING
READ ALL INSTRUCTIONS
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
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.
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.
23. Ensure the switch is in the off posi-
tion before inserting battery pack.
Inserting the battery pack into power
tools that have the switch on invites
accidents.
24. Recharge only with the charger speci-
fi ed by the manufacturer. A charger
that is suitable for one type of battery
pack may create a risk of fi re when used
with another battery pack.
25. Use power tools only with specifi cally
designated battery packs. Use of any
other battery packs may create a risk of
injury and fi re.
26. 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 fi re.
27. Under abusive conditions, liquid may
be ejected from the battery, avoid
contact. If contact accidentally occurs, fl ush with water. If liquid con-
tacts eyes, additionally seek medical
help. Liquid ejected from the battery
may cause irritation or burns.
SERVICE
28. 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
Symbology
1. Maintain labels and nameplates. These carry important information. If unreadable or
missing, contact a MILWAUKEE service facility for a free replacement.
2. 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.
3. Hold 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.
4. Keep hands away from all cutting edges and moving parts.
5. Wear ear protectors with impact drill. Exposure to noise can cause hearing loss.
6. Use auxiliary handles supplied with the tool. Loss of control can cause personal
injury.

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 bit comes to a complete
stop before laying the tool down.
Electric Brake
The electric brake engages when the trigger
is released, causing the bit to stop and allowing you to proceed with your work. Generally,
the bit stops within two seconds. However,
there may be a delay between the time
you release the trigger and when the brake
engages. Occasionally the brake may miss
completely. If the brake misses frequently,
the tool needs servicing by an authorized
MILWAUKEE service facility.
Drilling
Set both the hammer/drill and torque selector
collars to the drill positions.
Place the bit on the work surface and apply fi rm pressure before starting. Too much
pressure will slow the bit and reduce drilling
effi ciency. Too little pressure will cause the
bit to slide over the work area and dull the
point of the bit.
If the tool begins to stall, reduce pressure
slightly to allow the bit to regain speed. If
the bit binds, reverse the motor to free the
bit from the workpiece.
Cold Weather Operation
The V28 Lithium-Ion battery pack can be
used in temperatures down to -4°F. When
the battery pack is very cold, it may pulse for
the fi rst minute of use to warm itself up. Put
the battery pack on a tool and use the tool in
a light application. After about a minute, the
pack will have warmed itself up and operate
normally.
APPLICATIONS
WARNING
To reduce the risk of electric shock,
check work area for hidden pipes
and wires before drilling or driving
screws.
Drilling in Wood, Composition Materials
and Plastic
When drilling in wood, composition materials
and plastic, start the drill slowly, gradually
increasing speed as you drill. When drilling
into wood, use wood augers or twist drill bits.
Always use sharp bits. When using twist drill
bits, pull the bit out of the hole frequently to
clear chips from the bit fl utes. T o reduce the
chance of splintering, back work with a piece
of scrap wood. Select low speeds for plastics
with a low melting point.
Drilling in Metal
When drilling in metal, 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 hammer-drill 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.
Both actions will damage the carbide.
Driving Screws and Nut Running
Drill a pilot hole when driving screws into
thick or hard materials. Set the torque selector collar to the proper position and set
the speed to low. Use the proper style and
size screwdriver bit for the type of screw
you are using.
With the screwdriver bit in the screw, place
the tip of the screw on the workpiece and
apply fi rm pressure before pulling the trig-
ger. Screws can be removed by reversing
the motor.
Overloading
Continuous overloading may cause permanent damage to tool or battery pack.
WARNING
High rotational force. To reduce the
risk of injury, always hold or brace
securely. Always use side handle
on tools.
Bit Binding
A high rotational force occurs when a bit
binds. If the bit binds, the tool will be forced
in the opposite direction of the bit rotation.
Bits may bind if they are misaligned or when
they are breaking through a hole. Wood
boring bits can also bind if they run into
nails or knots. Be prepared for bit binding
situations.
To reduce the chance of bit binding:
• Use sharp bits. Sharp bits are less likely
to bind when drilling.
• Use the proper bit for the job. There are bits
that are designed for specifi c purposes.
• Use caution when drilling pitchy, knotty,
wet or warped material or when drilling in
material that may contain nails.
