_,WARNING! Read and understand all
instructions. Failure to follow all instructions
listed below may result in electric shock,
fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
• Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
• 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. Use in well
ventilated areas only.
• Keep bystanders, children, and visitors
away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
• Double insulated tools are equipped
with a polarized plug (one blade is
wider than the other.) This plug will fit
in a polarized outlet only one way. If
the plug does not fit fully in the outlet,
reverse the plug. If it still does not fit,
contact a qualified electrician to install
a polarized outlet. Do not change the
plug in any way. Double Insulation []
eliminates the need for the three wire
grounded power cord and grounded
power supply system.
• Avoid body contact with grounded
surfaces such as pipes, radiators,
ranges and refrigerators. There is an
increased risk of electric shock if your
body is grounded.
• Don't expose power tools to rain or
wet conditions. Water entering a power
tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the
cord to carry the tools or pull the plug
from an outlet. Keep cord away from
heat, oil, sharp edges or moving parts.
Replace damaged cords immediately.
Damaged cords increase the risk of
electric shock.
• When operating a power tool outside,
use an outdoor extension cord marked
"W-A" or "W." These cords are rated for
outdoor use and reduce the risk of electric
shock.
Personal Safety
• Stay alert, watch what you are doing
and use common sense when
operating a power tool. Do not use tool
while tired or under the influence of
drugs, alcohol, or medication. A
moment of inattention while operating
power tools may result in serious personal
injury,
• Dress properly. Do not wear loose
clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves
away from moving parts. Loose clothes,
jewelry, or long hair can be caught in
moving parts. Air vents cover moving
parts and should be avoided.
• Avoid accidental starting. Be sure
switch is off before plugging in.
Carrying tools with your finger on the
switch or plugging in tools that have the
switch on invites accidents.
• Remove adjusting keys or wrenches
before turning the tool on. A wrench or
a key that is left attached to a rotating part
of the tool may result in personal injury.
• Do not overreach. Keep proper footing
and balance at all times. Proper footing
andbalanceenablesbettercontrolofthe
toolinunexpectedsituations.
• Use safety equipment. Always wear
eye protection. Dust mask, non-skid
safety shoes, hard hat, or hearing
protection must be used for appropriate
conditions.
Tool Use and Care
• Use clamps or other practical way to
secure and support the workpiece to a
stable platform. Holding the work by
hand or against your body is unstable and
may lead to loss of control.
• Do not force tool. Use the correct tool
for your application. The correct tool will
do the job better and safer at the rate for
which it is designed.
• Do not use tool if switch does not turn
it on or off. Any tool that cannot be
controlled with the switch is dangerous
and must be repaired.
• Disconnect the plug from the power
source before making any
adjustments, changing accessories, or
storing the tool. Such preventive safety
measures reduce the risk of starting the
tool accidentally.
• Store idle tools out of reach of children
and other untrained persons. Tools are
dangerous in the hands of untrained
users.
• Maintain tools with care. Keep cutting
tools sharp and clean. Properly
maintained tools, with sharp cutting
edges are less likely to bind and are
easier to control.
• Check for misalignment or binding of
moving parts, breakage of parts, and
any other condition that may affect the
tools operation. If damaged, have the
tool serviced before using. Many
accidents are caused by poorly
maintained tools.
• Use only accessories that are
recommended by the manufacturer for
your model. Accessories that may be
suitable for one tool, may become
hazardous when used on another tool.
• Use only accessories recommended
for this tool that are sold by Sears or a
Craftsman outlet. Use of any
accessories purchased elsewhere may
be hazardous, and will also void your
warranty.
Service
• Tool service must be performed only by
qualified repair personnel. Service or
maintenance performed by unqualified
personnel could result in a risk of injury.
• When servicing a tool, use only
identical replacement parts. Follow
instructions in the Maintenance section
of this manual. Use of unauthorized parts
or failure to follow Maintenance
Instructions may create a risk of electric
shock or injury.
_ecific Safety Rules
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 paints,
crystalline silica from bricks and
cement and other masonry products, and
arsenic and chromium from
chemically-treated lumber. (CCA)
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.
• Avoid prolonged contact with dust
from power sanding, sawing,
grinding, drilling, and other
construction activities. Wear
protective clothing and wash
exposed areas with soap and water.
Allowing dust to get into your mouth,
eyes, or lay on the skin may promote
absorption of harmful chemicals.
-_ WARNING: Use of this tool can
generate and/or disburse dust, which
may cause serious and permanent
respiratory or other injury. Always use
NIOSH/OSHA approved respiratory
protection appropriate for the dust
exposure. Direct particles away from face
and body.
_, CAUTION: Wear appropriate hearing
protection during use. Under some
conditions and duration of use, noise from
this product may contribute to hearing
loss.

Warnings and Instructions
Sanding Lead Base Paint
Sanding of lead based paint is NOT
RECOMMENDED due to the difficulty
of controlling the contaminated dust.
The greatest danger of lead poisoning
is to children and pregnant women.
Since it is difficult to identify whether
or not a paint contains lead without a
chemical analysis, we recommend the
following precautions when sanding
any paint:
Personal Safety
• No children or pregnant women should
enter the work area where the paint
sanding is being done until all clean up is
completed.
• A dust mask or respirator should be worn
by all persons entering the work area.
The filter should be replaced daily or
whenever the wearer has difficulty
breathing.
NOTE: Only those dust masks suitable
for working with lead paint dust and
fumes should be used. Ordinary painting
masks do not offer this protection. See
your hardware dealer for the proper
(NIOSH approved) mask.
• NO EATING, DRINKING or SMOKING
should be done in the work area to
prevent ingesting contaminated paint
particles. Workers should wash and clean
up BEFORE eating, drinking or smoking.
Articles of food, drink, or smoking should
not be left in the work area where dust
would settle on them.
Environmental Safety
• Paint should be removed in such a
manner as to minimize the amount of
dust generated.
• Areas where paint removal is occurring
should be sealed with plastic sheeting of
4 mils thickness.
• Sanding should be done in a manner to
reduce tracking of paint dust outside the
work area.
Cleaning And Disposal
• All surfaces in the work area should be
vacuumed and thoroughly cleaned daily
for the duration of the sanding project.
Vacuum filter bags should be changed
frequently.
• Plastic drop cloths should be gathered up
and disposed of along with any dust
chips or other removal debris. They
should be placed in sealed refuse
receptacles and disposed of through
regular trash pick-up procedures. During
clean up, children and pregnant women
should be kept away from the immediate
work area.
• All toys, washable furniture and utensils
used by children should be washed
thoroughly before being used again.
Motor
Be sure your power supply agrees with
nameplate marking. 120 Volts AC only
means your tool will operate on standard
60 Hz household power. Do not operate
AC tools on DC. A rating of 120 volts
AC/DC means that your tool will operate
on standard 60 Hz AC or DC power. This
information is printed on the nameplate.
Lower voltage will cause loss of power
and can result in over-heating. All
Craftsman tools are factory-tested; if this
tool does not operate, check the power
supply.
Extension Cords
Make sure the extension cord is in good
condition before using. Always use the
proper size extension cord with the tool -
that is, proper wire size for various lengths
of cord and heavy enough to carry the
current the tool will draw. Use of an
undersized cord will cause a drop in line
voltage resulting in loss of power and
overheating. For proper size cords see
chart below.
