GENERAL SAFETY RULES-FOR ALL POWER TOOLS
WARNING!
READ ALL INSTRUCTIONS
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 batteryopearted (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 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 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 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 at-
tached 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 extraction and
collection facilities, ensure these
are connected and properly used.
Use of these devices can reduce dustrelated hazards.
POWER TOOL USE AND CARE
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 preventive safety mea-
sures 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 acci-
dents 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.
SERVICE
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.
32
SPECIFIC SAFETY RULES
FUNCTIONAL DESCRIPTION
1. 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.
2. Maintain labels and nameplates. These carry important information. If
unreadable or missing, contact a MILWAUKEE service facility for a free replacement.
3. 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.
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.
