USING SANDING BACKING PADS (FIG. 15)

Choose the proper grit sanding discs for your application. Sanding discs are available in various grits. Coarse grits yield faster material

removal rates and a rougher finish. Finer grits yield slower material removal and a smoother finish.

Begin with coarse grit discs for fast, rough material removal. Move to a medium grit paper and finish with a fine grit disc for optimal finish.

Coarse	16-30	grit
Medium	36-80	grit
Fine Finishing	100-120 grit
Very Fine Finishing	150 180 grit

1.Allow the tool to reach full speed before touching tool to the work surface.

2.Apply minimum pressure to work surface, allowing the tool to operate at high speed. Sanding rate is greatest when the tool operates at high speed.

3.Maintain a 5° to 15° angle between the tool and work surface. The sanding disc should contact approximately 1" (25.4 mm) of work surface.

4.Move the tool constantly ina straight line FIG.15 to prevent burning and swirling of work

surface. Allowing the tool to rest on the work surface without moving, or moving

the tool in a circular motion causes5°-15° burning and swirling marks on the work

surface.

5.Remove the tool from work surface before turning tool off. Allow the wheel to stop rotating before laying the tool down.

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:

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.

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 NIOSH-approved 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.

ENVIRON M ENTAL 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 mils thickness.
