General Safety Instructions
WARNING! Read and understand all instructions. Failure to follow all instruc-
tions listed below, may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
• 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 flam-
mable liquids, gases, or dust. Power tools create sparks which may ignite the dust or
• Keep bystanders, children, and visitors away while operating a power tool. Distractions
can cause you to lose control.
• 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. If 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.

• 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 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
• 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 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
• 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
Maintenance Instructions may create a risk of electric shock or injury.
Additional Safety Instructions for Sanders
• ALWAYS WEAR EYE PROTECTION.
• It is not advised to sandpaper painted surfaces that may contain lead. See page 2 for
Precautions to Take When Sanding Paint.
• Clean your tool out periodically.
• Empty dust bag frequently. Especially when sanding resin coated surfaces such as
polyurethane, varnish, shellac, etc. The accumulation of fine sanding dust particles may self
ignite and cause fire.
• Do not operate this tool for long periods of time. Vibration caused by the operating action
of this tool may cause permanent injury to fingers, hands, and arms. Use gloves to provide
extra cushion, take frequent rest periods, and limit daily time of use.
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 well ventilated area, and work with approved
safety equipment, such as those dust masks that are specially designed to filter out microscop-
• 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 pro-
mote 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.

the nameplate marking (Volts, 120 AC only). A Voltage decrease of more than 10% will cause
loss of power and overheating. All tools D
EWalt tools are factory tested; if this tool does not oper-
ate, check the power supply.
Attaching Abrasive Paper (Fig. 3)
Your sander is designed to use 1/4 sized sanding sheets. This size paper can be made by:
a. Cutting full sized (9" x 11") sandpaper into 1/4 sheets of 4-1/2" x 5-1/2".
b. Cutting 1/2 sheet sandpaper into two 4-1/2" x 5 1/2" sheets. Pre-cut 4-1/2" x 5-1/2" sandpa-
per is available at extra cost.
For normal operations, 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 1. Concentrate on softening the edges to be clamped.
2. Release clamp by pulling up on clamp lever and disengaging it from the tab on the base plate.
Fig. 2 (A).
3. Insert the 4-1/2" edge of the abrasive paper under the front paper clamp, as shown in Figure
3 until it hits the paper limiting ribs shown in the figure. Close the front paper clamp and hook
it into the lock position behind the tab on the base plate.
4. Stretch paper over sanding pad and insert under the opposite clamp in the same way.
5. If you are using the dust extraction feature, perforate the sand- paper with the provided paper
punch as shown in Figure 5.
Switch (Fig. 4)
To turn the unit on, depress the side of the dust protected switch that corresponds to the sym-
bol “I”. To turn the tool off, depress the side of the switch that corresponds to the symbol “O”.
See Figure 4.
Paper Punch (Fig. 5)
A paper punch is provided with your sander to let you perforate regular sandpaper to make dust
To perforate your sandpaper, 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 6. (Press the
punch into the pad as far as it will go.) Remove the paper punch and the paper is ready. An alter-
nate method of perforating the paper is to fasten the punch down to a suitable work surface and
press the sander (with the paper attached) down on the punch. Two holes are provided in the
punch for this purpose. Use #8 flat head screws.
