English 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 a. No children or pregnant women should enter the work area where the paint sanding is being done until all clean up is completed. b. 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 local hardware dealer for the proper N.I.O.S.H. approved mask. c. 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 a. Paint should be removed in such a manner as to minimize the amount of dust generated. b. Areas where paint removal is occurring should be sealed with plastic sheeting of 4 mils thickness. c. Sanding should be done in a manner to reduce tracking of paint dust outside the work area. CLEANING AND DISPOSAL a. 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. b. Plastic drop cloths should be gathered up and disposed of along with any dust particles 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. c. All toys, washable furniture and utensils used by children should be washed thoroughly before being used again. Lubrication Self lubricating bearings are used in the tool and periodic relubrication is not required. However, it is recommended that, once a year, you take or send the tool to a service center for a thorough cleaning and inspection. Cleaning 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 engineering polymers used to construct your sander. If you typically wrap the cord around the tool when you store it, leave a generous loop of cord such that the strain relief does not bend. This helps prevent premature cord failure. Repairs To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustment (including brush inspection and replacement) should be performed by a DEWALT factory service center, a DEWALT authorized service center or other qualified service personnel. Always use identical replacement parts. Application Notes SANDPAPER - GRIT TYPES Natural Abrasives Flint is the softest (Mohs' Scale 7)* of the common natural abrasives. It has a tan color and is very inexpensive. Garnet paper is harder than flint (Mohs' Scale 7.5) and is easily identified by its bright orange color. Even though it is not the hardest, the way the abrasive fractures gives you a good cutting edge for wood- 5
