Additional Safety Rules for Paint Removal
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:
PERSONAL SAFETY
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.
ENVIRONMENTAL SAFETY
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 mil thickness.
3.Sanding should be done in a manner to reduce tracking of paint dust outside the work area.
CLEANING AND DISPOSAL
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.

Motor
Be sure your power supply agrees with the nameplate marking. Voltage decrease of more than 10% will cause loss of power and overheating. DEWALT tools are factory tested; if this tool does not operate, check power supply.
WARNING: Accessories must be rated for at least the speed recommended on the tool warning label. Accessories running over rated speed can fly apart and cause injury. Accessory ratings must always be above tool speed as shown on tool nameplate.
OPERATION
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. Be sure the switch is in the “OFF” position. An accidental start-up can cause injury.
WARNING: Never modify the power tool or any part of it. Damage or personal injury could result.
Attaching Abrasive Paper (Fig. 1, 2)
Use 5" (127 mm) sanding discs with an 8-hole dust extraction pattern which attach to the sander with hook and loop.
1.Turn the sander over so that the sanding pad is facing upward.
2.Clean the dust from the vinyl pad face.
3.Hold the pad with one hand to keep it from rotating.
4.With the other hand, align the holes and place the disc directly on top of the pad.
NOTE: Do not use the sanding screen (the screen used for sanding drywall) directly on the hook and loop pad. The screen will not hold and will damage the hooks on the pad. The hooks will wear very rapidly if left in contact with the work surface while the tool is operating.
Switch (Fig. 3)
WARNING: To reduce the risk of injury, make sure the sander is not resting on the workpiece when the switch is turned on.
To turn unit on, depress the side of the dust-protected switch (A) that reads “ON” and corresponds to the symbol “I.” To turn the unit off, depress the side of the switch that reads “OFF” and corresponds with the symbol “O.”
Speed Control Dial (Fig. 4)
The speed control dial (B) allows you to increase or decrease the speed from 7,000-12,000 orbits per minute. The optimal speed setting for each application is very much dependent on personal preference. Generally, you will want to use a higher setting on harder materials and a lower setting on softer materials. Material removal rate increases as speed increases.
Pad Brake
These sanders are equipped with a pad brake that prevents over-speeding of the pad. If the tool is lifted off the work surface while the motor is running, the brake will limit pad rotation to no more than 500 RPM.
The plastic pad brake is used to provide the braking action. Eventually, this brake may require
replacement. If the brake fails to limit pad rotation, send the sander to a DEWALT service facility or replace the brake yourself using the information under Brake Replacement in the Maintenance
section of this manual.
Dust Collection (Fig. 5–7)
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. Be sure the switch is in the “OFF” position. An accidental start-up can cause injury.
WARNING: To reduce the risk of serious personal injury, NEVER operate this tool with perforated paper unless the dust collection system is in place.
WARNING: Empty dust collection system 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.
To use the dust collection system, install the dust container assembly (C and D) on the dust port
(E)as far as it will go. To empty the dust container, remove it and empty it into a trash receptacle. NOTE: To use your shop vacuum with the dust collection system, remove the dust container (D) by twisting it and pulling it away from the adapter. Remove the black tag (J), and attach your vacuum hose directly to the adapter port (C).
Using the Sander (Fig. 8)
To operate your sander, grasp it as shown in Figure 8 and turn it on. Move it in long, sweeping strokes along the surface, letting it do the work. Be sure to check your work often. This sander is capable of removing material rapidly, especially with coarse paper.
The random orbital action of your sander allows you to sand with the grain or at any angle across it for most sanding jobs. To produce the best finish possible, start with coarse grit sandpaper and change gradually to finer and finer paper. Vacuum and wipe the surface with a tack cloth between grit steps. Your sander is designed to sand into small or confined areas. Its small size and light weight make it ideal for overhead work.
The rate at which the dust container fills will vary with your workpiece and the coarsness of the sandpaper. For best results, empty the container frequently. When sanding painted surfaces (see Additional Safety Rules for Paint Removal), you may find that the sandpaper clogs with paint. A heat gun will work much better to remove paint before sanding. Follow all the safety instructions in the heat gun instruction manual.
MAINTENANCE
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. Be sure the switch is in the “OFF” position. An accidental start-up can cause injury.
Cleaning
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 this.
