General
Safety
Instructions
A
ARNING! Read and understand
all instructions.
Failure to follow all instructions listed
below may result in electric shock, fire and/or serious personal injui_.
SLAVE THESE
INSTRUCTIONS
WORK AREA
*
Keep your work area clean and well fit. Cluttered benches and dark areas invite accidents.
*
Do not operate power tools in explosive
atmospheres,
such as in the presence of flam-
mable liquids,
gases,
or dust.
Power tools create sparks which may ignite the dust or
fumes.
*
Keep bystanders,
children,
and visitors away while operating
a power tool Distractions
can cause you to lose control.
ELECTRICAL
SAFETY
*
Grounded
tools must be plugged
into an outlet
properly
installed
and grounded
in
accordance
with all codes and ordinances.
Never remove
the grounding
prong
or
modify the plug in any way. Do not use any adaptor plugs. Check with a qualified
elec-
trician if you are in doubt as to whether
the outlet is properly
grounded,
ff the tools
should electrically malfunction or break down, grounding provides a low resistance path to
carry electricity away from the user. Applicable
only to Class I (grounded)
tools.
*
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 []
elim-
inates the need for the three wire grounded power cord and grounded power supply system.
Applicable
only to Class II (double insulated)
tools.
* 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. When
using an extension cord, be sure to use one heavy enough to carry the current your product
will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and
overheating. The following table shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage num-
ber, the heavier the cord.

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 injui_.
*
Dress properly.
Do not wear loose clothing
or jewelry. Contain long hair. Keep your hair,
clothing, and gloves away from moving parts. Loose clothing, jewelry, or long hair can be
caught in moving parts. Air vents often cover moving parts and should also 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 and bal-
ance enables better control of the tool in unexpected situations.
*
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 preventative
safety measures reduce the risk of
starting the tool accidentally.
*
Store idle tools out of reach of children
and other untrained
persons.
Tools are dan-
gerous 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 tool's
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.
SERVICE
*
Tool service must be performed
only by qualified
repair personnel
Service or mainte-
nance 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 mainte-
nance instructions may create a risk of electric shock or injury.
Additional
Safety
Instructions
for Sanders
.
Accessories
must be rated for at least the speed recommended
on the tool warning
label Wheels and other accessories running over rated speed can fly apart and cause inju_
Accessory ratings must be above listed minimum wheel speed as shown on tool nameplate.
,
Hold tool by insulated gripping
surfaces
when performing
an operation
where the cut-
ting tool may contact hidden wiring or its own cord. Contact with a 'five" wire will make
exposed metal parts of the tool 'five" and shock the operator.
,
Always
wear eye protection
and a respirator
when sanding.
,
Sanding of lead-based
paint is not recommended.
See Precautions
To Take When
Sanding Paint for additional information before sanding paint.
,
Do not operate the unit without
the dust collection
bag.
,
Clean your tool out periodically.
,
Empty dust bag frequently,
especially
when sanding
resin coated surfaces
such as
polyurethane,
varnish, shellac, etc. Dispose of coated dust particles according to the finish
manufacturer's guidelines, or place in a metal can with a tight-fitting metal lid. Remove coated
dust particles from the premises daily. The accumulation of fine sanding dust particles may
serf ignite and cause fire.
,
Replace worn CFS disc when it causes high tool rpm. High tool rpm caused by a worn
out CFS disc may result in separation of sanding pad from the sander, possibly causing per-
sonal injui_. For instructions on replacing the CFS disc, see Tool Care.
_ WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other con-
struction activities contains chemicals known to cause cancer, birth defects or other reproduc-
tive 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 weft 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.
J_,CAUTION: Wear appropriate
hearing protection
during
use. Under some conditions and
duration of use, noise from this product may contribute to hearing loss.

Your DEWALT tool is powered by a DEWALT built motor. Be sure your power supply agrees with
the nameplate marking. (Volts, 120 AC only). Voltage decrease of more than 10% will cause loss
of power and overheating. All DEWALT tools are factory tested; if this tool does not operate,
check the power supply.
