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.
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.
SERVICE
PERSONAL SAFETY
23. Have your power tool serviced by a qualified repair person
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.
POWER TOOL USE AND CARE
page 2
using only identical replacement parts. This will ensure that
the safety of the power tool is maintained.
SPECIFIC SAFETY RULES
1. Hold power tools by insulated gripping surfaces when per-
forming 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 with impact drills. Exposure to noise can
cause hearing loss.
3. Keep hands away from all cutting edges and moving parts.
4. Maintain labels and nameplates. These carry important informa-
tion. 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 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.

Tighten
Loosen
WARNING!
To reduce the risk of injury, wear safety goggles or glasses
with side shields. Unplug the tool before changing
accessories or making adjustments.
1. 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.
2. When using drill bits, 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.
When using screwdriver bits, insert the bit far enough for the chuck
jaws to grip the bit shank. Tighten the chuck jaws by hand to align
the bit.
3. Place the chuck key in each of the three holes in the chuck, turning
it clockwise as shown. Tighten securely.
4. To remove the bit, insert the chuck key into one of the holes in the
chuck and turn it counterclockwise.
WARNING!
To prevent personal injury, always remove the chuck key
from the chuck after each use.
OPERATION
WARNING!
To reduce the risk of explosion, electric shock and property
damage, always check the work area for hidden electrical
wires or pipes when drilling.
Using Forward/Reverse Switch (Fig. 2)
Fig. 2
Forward/
Reverse
switch
1. For forward (clockwise) rotation, slide the forward/reverse
switch towards the front of the tool.
2. For reverse (counterclockwise) rotation, slide the forward/reverse
switch towards the back of the tool.
NOTE: To prevent damage to the motor, allow the tool to come to a
complete stop before reversing.
Starting, Stopping and Controlling Speed
1. To start the tool, pull the paddle switch.
2. To stop the tool, release the paddle switch.
3. To vary the driving speed, simply increase or decrease pressure on
the paddle switch. The further the paddle switch is pulled, the greater
the speed.
page 4
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 firm pressure. Begin drilling at a slow speed, gradually increasing the speed as you drill.
3. Use enough pressure on the tool to keep the bit drilling or driving
constantly, but do not push hard enough to stall the bit.
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.
Stalling
If the tool seems as if it is about to stall, maintain a firm grip and reduce
pressure slightly to allow the bit to regain speed. If the tool does stall,
release the paddle switch immediately . Reverse the motor , remove the bit
from the work and start again. Do not press the paddle switch on and off
in an attempt to start a stalled drill. This can damage the drill.
APPLICATIONS
MAINTENANCE
Selecting Bits
When selecting a bit, use the right type for your job. For best performance, always use sharp bits.
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 using twist drill
bits, pull the bit out of the hole frequently to clear chips from the bit flutes.
Use low speeds for plastics with a low melting point.
Drilling in Masonry
When drilling in masonry , 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 flow 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.
Drilling in Metal
When drilling in metal, use high speed steel twist drills or hole saws. Use
slow speeds for hard metals and high speeds for softer metals. 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.
Driving Screws
When driving screws, use the proper screwdriver bit for your job. After
drilling pilot and shank holes, start the screw slowly and increase the
speed as driving progresses. Set the screw by slowing to a stop. Do not
run screws down at excessive speeds. To remove screws, reverse the
motor.
WARNING!
To reduce the risk of injury, always unplug
your tool before performing any maintenance.
Never disassemble the tool or try to do any
rewiring on the tool's electrical system. Contact
a MILWAUKEE service facility for ALL repairs.
Maintaining Tools
Keep your tool in good repair by adopting a regular maintenance program. Before use, examine the general condition of your tool. Inspect
guards, switches, tool cord set and extension cord for damage. Check
for loose screws, misalignment, binding of moving parts, improper mounting, broken parts and any other condition that may affect its safe operation. If abnormal noise or vibration occurs, turn the tool off immediately
and have the problem corrected before further use. Do not use a damaged tool. Tag damaged tools “DO NOT USE” until repaired
(see “Repairs”).
Under normal conditions, relubrication is not necessary until the motor
brushes need to be replaced. After six months to one year, depending on
use, return your tool to the nearest MILWAUKEE service facility for the
following:
• Lubrication
• Brush inspection and replacement
• Mechanical inspection and cleaning (gears, spindles, bearings,
housing, etc.)
• Electrical inspection (switch, cord, armature, etc.)
• Testing to assure proper mechanical and electrical operation
Cleaning
Clean dust and debris from vents. Keep the tool handles clean, dry and
free of oil or grease. Use only mild soap and a damp cloth to clean your
tool since certain cleaning agents and solvents are harmful to plastics
and other insulated parts. Some of these include: gasoline, turpentine,
lacquer thinner, paint thinner, chlorinated cleaning solvents, ammonia
and household detergents containing ammonia. Never use flammable or
combustible solvents around tools.
