2. Since it is difficult to identify whether or not a paint contains lead
without a chemical analysis, we recommend the following precau-
tions 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 prop-
er 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 thorough-
ly cleaned daily for the duration of the sanding project. Vacuum fil-
ter 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 reg-
ular 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 D WALT factory service center, a D
E
rized 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 iden-
tified 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-
working.
