pad and sanding disc while depressing the spindle
lock button.
Using Sanding Backing pads (Fig. O)
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.

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.
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.
