4. Tighten the clamp nut by hand. Then depress the spindle lock

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.

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 san ding disc should contact approximately 1" (25.4 mm) of
work surface.
4. Move the tool constantly in a straight line
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 causes
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.

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 mils thickness.
