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.

O
NOTE: To engage the hammering mecha-
nism, maintain pressure on the bit. When
pressure on the bit is released, the hammering action will stop.
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.
6 7
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 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.
Center Pin
Guide Plate
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
Selecting Bits
When selecting a bit, use the right type for
your job. For best performance, always use
sharp bits.
Drilling
1. Before drilling, be sure the workpiece is
clamped securely. Use backing material
to prevent damage to the workpiece
during breakthrough.
2. When starting a hole, place the drill bit on
the work surface and apply fi rm pressure.
Begin drilling at a slow speed, gradually
increasing the speed as you drill.
3. Always apply pressure in line with the bit.
Use enough pressure to keep the drill
biting, but do not push hard enough to
stall the motor.
4. Reduce pressure and ease the bit
through the last part of the hole. While
the tool is still running, pull the bit out of
the hole to prevent jamming.
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. To reduce the
chance of splintering, back work with a piece
of scrap wood. Select low speeds for plastics
with a low melting point.

RÈGLES GÉNÉRALES DE SÉCURITÉ POUR LES OUTILS
ALIMENTÉS PAR BATTERIE
AVERTISSEMENT
LIRE SOIGNEUSEMENT TOUTES LES INSTRUCTIONS
Le non respect des instructions ci-après peut entraîner des chocs électriques, des
incendies et/ou des blessures graves. Le terme «outil électrique» fi gurant dans les
avertissements ci-dessous renvoie à l’outil électrique à alimentation par le réseau
(à cordon) ou par batterie (sans fi l).
CONSERVER CES INSTRUCTIONS
SÉCURITÉ DU LIEU
DE TRAVAIL
1. Maintenir la zone de travail propre et bien
éclairée. Les zones encombrées ou mal
éclairées sont favorables aux accidents.
2. Ne pas utiliser d’outil électrique dans
une atmosphère explosive, telle
qu’en en présence de liquides, de
gaz ou de poussières infl ammables.
Les outils électriques génèrent des
étincelles qui peuvent enfl ammer les

3. Tenir les enfants et les personnes
non autorisées à l’écart pendant le
fonctionnement d’un outil électrique.
Un manque d’attention de l’opérateur risque
de lui faire perdre le contrôle de l’outil.
SÉCURITÉ ÉLECTRIQUE
4. La fi che de l’outil électrique doit cor-
respondre à la prise d’alimentation.
Ne jamais modifier la fiche d’une
manière quelconque. Ne pas utiliser
d’adaptateur avec les outils électriques mis à la terre (à la masse).
Des fi ches non modifi ées et des prises
d’alimentation assorties réduisent le
risque de choc électrique.
5. Éviter tout contact corporel avec des
surfaces reliées à la masse ou à la
terre telles que tuyaux, radiateurs,
cuisinières et réfrigérateurs. Un risque
de choc électrique plus élevé existe si le
corps est relié à la masse ou à la terre.
6. Ne pas exposer les outils électriques
à la pluie ou à l’humidité. Le risque de
choc électrique augmente si de l’eau
s’infi ltre dans un outil électrique.
7. Prendre soin du cordon. Ne jamais
utiliser le cordon pour transporter,
tirer ou débrancher l’outil électrique.
Tenir le cordon à l’écart de la chaleur ,
