General Power Tool Safety Warnings
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings
and instructions may result in electric shock, fire and/or serious injury.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-
operated (cordless) power tool.
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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
c) Keep children and bystanders away while operating a power tool. Distractions can cause
you to lose control.
a) 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.
b) 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.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
d) 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.
e) 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.
f) If operating a power tool in a damp location is unavoidable, use a ground fault circuit
interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.
a) 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.
b) Use personal protective equipment. Always wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off position before
connecting to power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energizing power tools that have the
switch on invites accidents.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of dust collection can reduce dust-
related hazards.
a) 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.
b) 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.
c) 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 measures reduce the risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfamiliar
with the power tool or these instructions to operate the power tool. Power tools are
dangerous in the hands of untrained users.
e) 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.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits, etc. in accordance with these
instructions, 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
a) 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.
Additional Safety Instructions for Sanders
Accessories must be rated for at least the speed recom mended on the tool warning
label. Wheels and other accessories running over rated speed can fly apart and cause injury.
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
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.
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 self
ignite and cause fire.
Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or long
hair can be caught in moving parts.
An extension cord must have adequate wire size (AWG or American Wire Gauge) for
safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is
16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. When using more than one extension to make up the
total length, be sure each individual extension contains at least the minimum wire size. The following
table shows the correct size to use depending on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also use
face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:
ANSI Z87.1 eye protection (CAN/CSA Z94.3),
ANSI S12.6 (S3.19) hearing protection,
NIOSH/OSHA/MSHA respiratory protection.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to the State of California 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.
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 disperse 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.
WARNING: Always wear proper personal hearing protection that conforms to ANSI
S12.6 (S3.19) during use. Under some conditions and duration of use, noise from this product
may contribute to hearing loss.

Attaching Abrasive Paper (Fig. 2–6)
CAUTION: Turn off and unplug the tool before making any adjustments or removing or installing
attachments or accessories. Be sure the switch is in the OFF position.
Your sander is designed to use 1/4-sized sanding sheets. Pre-cut 4-1/2" x 5-1/2" sandpaper is
available at extra cost.
TO MAKE 4-1/2" X 5-1/2" SANDPAPER
a. Cut full-sized (9" x 11") sandpaper into 1/4 sheets of 4-1/2" x 5-1/2".
b. Cut 1/2 sheet sandpaper into two 4-1/2" x 5-1/2" sheets.
For normal operation, assemble the abrasive paper to your unit as follows:
1. Soften the stiff sandpaper by pulling it over the 90° edge of a table or other straight edge, as
shown in Figure 2. Concentrate on softening the edges to be clamped.
2. Release the rear paper clamp (F) by pulling up on the side clamp levers (G) and disengaging
them from the tabs (H) on the base plate/pad (D) as shown in Figure 3.
3. Disengage the front paper clamp (B, Fig. 4) by applying and holding pressure on the front clamp
button (C) while inserting the 4-1/2" edge of the abrasive paper under the front paper clamp (B)
until if hits the paper-limiting ribs (E). Release the front paper clamp to secure the front of the
4. Stretch paper over the base plate/pad (D) and begin to pivot the rear paper clamp (F) around
to its locking position. Lock one side clamp lever (G) by placing it behind the tab (H, Fig. 5) on
the base plate/pad and then repeat with the second side clamp lever.
5. If you are using the dust extraction feature, perforate the sandpaper (see Paper Punch).
1. Place the tool on a table, base plate/pad (D) up.
2. Place the sanding sheet directly on top of the base plate/pad (D).
3. Hold the base plate/pad with one hand and align the dust extraction holes (L).
4. Press the sheet firmly onto the base plate/pad.
Switch (Fig. 1)
To turn the unit on, depress the side of the dust-protected switch (A) that corresponds to the
symbol “I”. To turn the tool off, depress the side of the switch that corresponds to the symbol “O”.
Paper Punch (Fig. 7)
CAUTION: Turn off and unplug the tool before making any adjustments or removing or installing
attachments or accessories. Be sure the switch is in the OFF position.
A paper punch (M) is provided with your sander to let you perforate regular sandpaper to make
dust collection possible.
Install the sandpaper on the tool as instructed in this manual. With the sander turned off and
unplugged, place the paper punch on the paper so that the tabs at the edges of the punch are
against any two adjacent sides of the sanding pad, as shown. Press the punch against the pad so
that the 8 points penetrate the paper, as shown in Figure 7. (Press the punch into the pad as far as
it will go.) Remove the paper punch and the paper is ready.
An alternate method of perforating the paper is to securely fasten the punch to a suitable work
surface. Two holes are provided in the punch for this purpose. Use #8 flat head screws. Press the
sander (with the paper attached) down on the punch.
Dust Extraction (Fig. 1, 8)
Your sander has a built-in vac-adapter (I) which allows either the supplied dust bag (J) or a shop
vacuum system to be connected. The built-in outlet utilizes the DeWALT AirLock connection making
it compatible with the DeWALT dust extractor.
1. While holding the sander, fit the dust bag collar (K) to the vac-adapter (I) as shown in Figure 8.
2. Turn the collar (K) clockwise to lock the dust bag (J) in place.
1. While holding the sander, turn the collar (K) counterclockwise to unlock the dust bag (J).
2. Remove dust bag from the sander and gently shake or tap the dust bag to empty.
3. Reattach the dust bag back onto the outlet and lock into place by turning the dust bag collar
You may notice that all the dust will not come free from the bag. This will not affect sanding
performance but will reduce the sander’s dust collection efficiency. To restore your sander’s dust
collection efficiency, depress the spring inside the dust bag when you are emptying it and tap it on
the side of the trash can or dust receptacle.
CAUTION: Never operate these tools unless the dust collector is in place. Sanding dust
exhaust may create a breathing hazard.
WARNING: To reduce the risk of injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
NOTICE: This sander is not to be used in drywall applications.
To operate your sander, grasp it as shown in Figure 9A or 9B and turn it on. Move it in long,
sweeping strokes along the surface being sanded, letting the sander do the work. Pushing down
on the tool while sanding actually slows the removal rate and produces an inferior quality surface.
Be sure to check your work often, this sander is capable of removing material rapidly, especially
with coarse paper.
Your sander is designed to sand flush on three sides for sanding in corners, and its small size and
light weight make it ideal for overhead work.
The orbital action of your sander allows you to sand with the grain or at any angle across it for most
sanding jobs. On the final sanding steps, as discussed below, a better finish will result if you sand
only with the grain.
To produce the best finish possible, start with coarse grit sandpaper and change gradually to finer
and finer paper. A final sanding with a piece of well-worn fine sandpaper will produce a professional-
looking finish that in many cases will need no hand sanding at all. The rate at which the dust
collection bag will fill up will vary with the type of material being sanded and the coarseness of the
sandpaper. For best results, empty the bag frequently and check the opening for clogging.
When sanding painted surfaces, you may find that the sandpaper loads up and clogs with
paint. A heat gun will work much better to remove paint before sanding. FOLLOW ALL SAFETY
Precautions to Take When Sanding Paint
1. 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.
2. 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:
FIG. 1
FIG. 8
1. No children or pregnant women should enter the work area where the paint sanding is being
done until all clean-up is completed.
2. 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. See your local
hardware store for the proper NIOSH-approved dust mask.
3. 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.
1. Paint should be removed in such a manner as to minimize the amount of dust generated.
2. Areas where paint removal is occurring should be sealed with plastic sheeting of 4 mils
3. Sanding should be done in a manner to reduce tracking of paint dust outside the work area.
1. 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.
2. 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.
3. All toys, washable furniture and utensils used by children should be washed thoroughly
before being used again.
Tool Care
Keep your machine as clean as possible by wiping with a clean cloth and blowing through it
with air after every 5 hours of use.
Don’t use harsh chemicals or solvents to clean the tool. These chemicals could seriously
damage the plastic.
Avoid overloading your sander. Overloading will result in a considerable reduction in speed and
efficiency and the unit will become hot. In this event, run sander at a “no load” condition for a
minute or two.
Brush inspection and replacement should be completed by your local dealer or authorized
service center.
WARNING: To reduce the risk of injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once a week. To
minimize the risk of eye injury, always wear ANSI Z87.1 approved eye protection when performing
