GENERAL SAFETY RULES FOR ALL POWER TOOLS
WARNING!
Failure to follow all instructions listed below may result in electric shock, fire 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 flammable 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. Unmodified 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 suitable for outdoor use. Use of a cord suitable for outdoor
use reduces the risk of electric shock.
PERSONAL SAFETY
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 bat-
tery 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 allow persons unfamiliar with the power tools or these
instructions to operate power tools. Power tools are danger-
ous 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 accor-
dance 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.
POWER TOOL USE AND CARE
SERVICE
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 influence 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 finger 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 extrac-
tion and collection facilities, ensure these are connected
and properly used. Use of these devices can reduce dust-re-
lated hazards.
page 2
23. Have your power tool serviced by a qualified repair person
using only identical replacement parts. This will ensure that
the safety of the power tool is maintained.
SPECIFIC SAFETY RULES
1. Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.
2. Wear ear protectors with impact drills. Exposure to noise can cause hearing loss.
3. 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.
4. Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a free
replacement.
5. 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 specifically designed to filter out
microscopic particles.

GROUNDING EXTENSION CORDS
WARNING!
Improperly connecting the grounding wire can result in the
risk of electric shock. Check with a qualified 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 fit
the outlet, have a proper outlet installed by a qualified
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.
Your 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
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 suffix 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 qualified person before using it.
Protect your extension cords from sharp objects, excessive heat
and damp or wet areas.

TOOL ASSEMBLY
WARNING!
To reduce the risk of injury, always unplug tool before
attaching or removing accessories or making adjustments.
Use only specifically recommended accessories. Others
may be hazardous.
Installing Bits into Keyed Chucks (Fig. 1)
Fig. 1
1. Unplug tool.
2. Open the chuck jaws wide enough to insert the bit. Be sure the bit
shank and chuck jaws are clean. Dirt particles may prevent the bit
from lining up properly.
3. Insert the bit into the chuck. Center the bit in the chuck jaws and lift
it about 1/16" off of the bottom. Tighten the chuck jaws by hand to
align the bit.
4. Place the chuck key in each of the three holes in the chuck, turning
it clockwise to tighten the chuck securely.
NOTE: Never use a wrench or means other than a chuck key to
tighten or loosen the chuck.
5. To remove the bit, insert the chuck key into one of the holes in the
chuck and turn it counterclockwise.
Bit Selection
Use sharp bits. Sharp bits are less likely to bind when drilling.
Use the proper bit for the job. There are many types of bits designed
for specific purposes. Check the information on the bit's packaging
for proper usage.
Do not use bits larger than the rated capacity of the drill. Gear
damage or motor overload may result (see "Specifications").
Side Handle
The side handle can be installed on either side of the tool. To install the
side handle, thread it into the socket on the desired side of the tool and
tighten it securely.
Handle Rotation (Fig. 2, 3, & 4)
Fig. 2
Fig. 3
Fig. 4
This tool is equipped with an adjustable switch handle that allows the
user to adjust the handle to three positions (90° apart) for optimum
operating position.
1. Unplug the tool.
2. Press in and hold the handle rotation release button and rotate the
switch handle to one of the three handle positions.
3. Release the handle rotation release button. The adjustable handle
has detents which allow the handle to snap into position. Make sure
the handle snaps firmly into position and does not rotate.
The tool will not operate if the handle is not locked securely in one of the
three positions.
WARNING!
To reduce the risk of injury, always wear eye protection.
Chuck Removal (Fig. 5)
This tool is equipped with a threaded spindle to hold the chuck. Before
removing the chuck, unplug the tool and open the chuck jaws. A lefthanded thread screw is located inside the chuck to prevent the chuck
from loosening when the tool is operated in reverse direction. Remove
the screw by turning it clockwise. To remove the chuck, hold the tool so
that only the side of the chuck rests firmly and squarely on a solid
workbench. Insert the chuck key or a chuck remover bar in one of the
keyholes. Turn the chuck so the key is at about a 30° angle to the bench
top and strike the key
sharply with a hammer so the
chuck turns in a counterclockwise direction (looking
from the front of the tool).
This should loosen the chuck
from the spindle which has
a right hand thread making it
easy to remove the chuck by
hand.
NOTE: When replacing the
chuck, always replace the
left hand thread screw in the
chuck.

OPERATION
WARNING!
To reduce the risk of injury, wear safety goggles or glasses
with side shields.
WARNING!
To reduce the risk of personal injury when drilling, hold tool
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.
WARNING!
To reduce the risk of injury, hold or brace securely. Always
be prepared for bit binding and drill reaction.
Clutch
The Super Hawg has a clutch that is active when the tool is running in
low speed only. The clutch disengages the bit from the geartrain to
protect the tool. When a high load is encountered, the clutch will slip and
a ratcheting sound will be heard. Release the trigger switch when the
clutch begins to slip (see "Bit Binding"). Continuous use of the tool when
the clutch is slipping will reduce the life of the mechanism.
Bit binding (Fig. 6)
The direction of reaction is always opposite of the direction of bit rotation. Reaction is even more likely to occur when enlarging already existing holes and at the point when the bit breaks through the other side of
the material.
If the bit does bind:
1. Release the trigger immediately.
2. Reverse the motor.
3. Remove the bit from the work and start again.
4. Do not pull the trigger on and off to attempt to start a stalled bit. This
will damage the drill.
Bracing for forward rotation (Fig. 7 & 8)
Fig. 7
C
B
Fig. 6
B
A
If the bit binds, the drill will suddenly react in the opposite direction of the
rotation of the bit. Figure 6 shows the path of reaction, (B) if the drill bit
binds while being driven in forward (A). Reduce the chances of a sudden reaction by following the instructions listed below. Prepare for a
sudden reaction by holding or bracing securely.
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 many types of bits designed
for specific purposes.
Use the proper speed for the size bit. Larger bits should be run at
the lower speed (see "Specifications"). Driving larger bits at high
speeds will increase the chance of the bit binding and increase the
chance of reaction.
Keep selfeed bits aligned with the work surface so bits go in straight
(see "Drilling").
Avoid drilling warped, wet, knotty, and/or pitchy material if possible.
Avoid drilling in material that you suspect contains hidden nails or
other things that may cause the bit to bind.

When drilling in forward, the bit will rotate in a clockwise direction. If the
bit binds in the hole, the bit will come to a sudden stop and drill will
suddenly react in a counterclockwise direction.
There are two ways to properly brace the Super Hawg for forward
rotation (Fig. 7 & 8).
A. Forward (clockwise) rotation
B. Reaction
C. Brace drill with side handle here
D. Brace drill with gearcase here
If the bit binds, the side handle or the gearcase braced against the stud
will hold the drill in position.

Use the shift knob to select High or Low speed (Fig. 11). High speed
(1750 RPM) is the low torque setting. Low speed (450 RPM) is the high
torque setting. See the "Specifications" section for bit capacity limits
under high and low speeds.
Always turn off the switch and shift speeds while the tool is stopped.
Never shift the drill while it is moving or when it is under load.
NOTE: The clutch is active in low speed only.

When drilling in reverse, the bit will rotate in a counterclockwise direction. If the bit binds in the hole, the bit will come to a sudden stop and the
drill will suddenly react in a clockwise direction.
There are two ways to properly brace the Super Hawg for reverse
rotation (Fig. 9 & 10).
A. Reverse (counterclockwise) rotation
B. Reaction
C. Brace drill with side handle here
D. Brace drill with motor gearcase here
If the bit binds, the side handle or the gearcase braced against the stud

Reversing (Fig. 12)
Drilling
Fig. 12
Forward
(clockwise)
Reverse
(counterclockwise)
A reversing switch is located opposite the trigger switch for removal of
bits from holes. Permit the motor to come to a complete stop before
reversing. Reversing the tool with the gears in motion may cause severe
damage. When removing selfeed bits from partially drilled holes, flick the
trigger switch when the tool is in reverse to free the threaded pilot
screw. When the threads are loose, lift the bit from the workpiece with
the motor stopped.
Starting, Stopping and Controlling Speed
WARNING!
To reduce the risk of injury, keep hands and cord away from
the bit and all moving parts.
1. To start the tool, pull trigger switch.
2. To stop the tool, release the trigger switch.
WARNING!
To reduce the risk of explosion, electric shock and property
damage, always check the work area for hidden pipes and
wires before drilling.
1. Before drilling, be sure the workpiece is clamped securely. A poorly
secured piece of material may result in personal injury or inaccurate
drilling. Use backing material to prevent damage to the workpiece
during breakthrough. When drilling in light gauge metal or wood, use
a wooden block to back up the material to prevent damage to the
workpiece.
2. When starting a hole, place the drill bit on the work surface and
apply firm pressure.
To start a selfeed bit, run the threaded feed screw into the work by
flicking the trigger switch, permitting the bit to coast until the teeth
contact the work surface. Align the bit properly before proceeding.
This will reduce cocking and jamming when starting.
When drilling in metal, mark the center of the hole to be drilled with a
center punch to give the bit a start and to prevent it from "walking."
Lubricate the drill bit with cutting oil when drilling iron or steel. Use a
coolant when drilling nonferrous metals such as copper, brass or
aluminum.
3. Always apply pressure in line with the bit. Use enough pressure to
keep the drill biting, but do not push hard enough to cause the bit to
bind.
When using twist drill bits, pull the bit out frequently to clear chips
from the flutes.
When using selfeed bits, if the clutch slips, pull the bit up very
slightly and then push it toward the workpiece. Repeat this several
times.
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.
When using selfeed bits, decrease the drilling pressure when the
feed screw point breaks through the workpiece. Proceed with steady,
even pressure.
