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. Keep hands away from all cutting edges and moving parts.
5. Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE Service facility for a
free replacement.
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 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.

Installing Bits into Keyed Chucks (Fig. 2)
Fig. 2
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. Then, 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 as shown. Tighten securely.
5. To remove the bit, insert the chuck key into one of the holes in the
chuck and turn it counterclockwise.
OPERATION
WARNING!
To reduce the risk of personal injury when drilling, always
hold tool by the 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!
When drilling, always hold the drill securely using the pipe
handle, or brace the drill against a solid fixed object in
preparation for a sudden reaction.
When drilling, never use your body to brace drill.
Never put your hands (or other body parts) between the part
of the drill being braced and the object it is being braced
against. Hands (or other body parts) that are in the path of
the reaction can be pinched, crushed, and broken.
Bit Binding (Fig. 4)
Fig. 4
WARNING!
To reduce the risk of injury, always wear eye protection.
Chuck Removal (Fig. 3)
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.

A
If the bit binds, the drill will suddenly react in the opposite direction of the
rotation of the bit. Figure 4 shows the path of reaction, (B) if the drill bit
binds while being driven in forward (A).The operator should reduce the
chances of a sudden reaction by following the instructions listed below.
The operator should also prepare for a sudden reaction by holding securely using the pipe handle or bracing against a solid fixed object.
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.
• 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.
The direction of reaction is always opposite of the direction of bit binding.
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.

Reversing (Fig. 7 & 8)
Fig. 7 Fig. 8
A reversing switch is located below (Fig. 7) or above (Fig. 8) 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, a flick of the trigger switch will free the threaded pilot screw.
When the threads are loose, lift the bit from the workpiece with the motor
stopped.
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.
Drilling
Before drilling, clamp the material down securely. A poorly secured piece
of material may result in personal injury or inaccurate drilling. When drilling in light gauge metal or wood, use a wooden block to back up the
material to prevent damage to the workpiece.
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.
T o st art 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. To reduce jamming on breakthrough,
decrease the drilling pressure when the feed screw point breaks through
the workpiece. Proceed with steady, even pressure.
A
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.
Figure 6 shows an example of a Compact Hole-Shooter properly braced
for reverse rotation.

C. Brace drill with pipe handle here
If the bit binds, the pipe handle or the motor housing braced against the
stud will hold the drill in position.

Speed Control Dial
Catalog number 1663-20 has a Speed Control Dial to provide electronic
speed control. (The trigger does not control the speed - it only turns the
tool on and off). The dial is located on rear of the handle. The dial has
positions numbered 1-8. Position 8 provides full speed at no load. Position 1 provides approximately 25% of the full no load speed. Reduced
speed can be useful for starting bits and obtaining the optimum speed for
a given bit size. Do not adjust the speed while drilling. This tool is furnished with Electronic Feedback to provide a more constant speed under
load.
