SANDING
PRECAUTIONS TO TAKE WHEN SANDING PAINT
• 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.
• 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
• No children or pregnant women should enter the work area where the paint sanding is being
done until all cleanup is completed.
• 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 dustmasks 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 NIOSH approved proper mask.
ENVIRONMENTAL SAFETY
• Paint should be removed in such a manner as to minimize the amount of dust
generated.
• Areas where paint removal is occurring should be sealed with plastic sheeting of 4 mils
thickness.
• Sanding should be done in a manner to reduce tracking of paint dust outside the work area.
GENERAL INFORMATION
HELPFUL HINTS
• Hold your angle grinder with one hand on the body and the other hand firmly around the
side handle as shown in Figure 9.
• Always position the guard so that as much of the exposed disc as possible is pointing
away from you.
• Be prepared for a stream of sparks when the disc touches the metal.
• Maintain an angle between the disc and work surface (Fig. 10) of approximately 30°
when grinding and 10°-15° when sanding ( Fig. 11) for best tool control, material
removal, and minimal loading.
:
Use extra care when grinding into a corner as a sudden, sharp
movement of the grinder may be experienced when the wheel contacts a secondary
surface.
:
Always wear eye protection while operating this power tool.
MAINTENANCE
CLEANING
Blowing dust and grit out of the motor housing using compressed air is a necessary
maintenance procedure.
:
Dust and grit from metal grinding often accumulate on interior surfaces
and could create an electrical shock hazard if not cleaned out.
Use only mild soap and a damp cloth to clean the tool. Never let any liquid get inside the
tool; never immerse any part of the tool into a liquid.
LUBRICATION
Porter Cable tools are properly lubricated at the factory and are ready for use. Tools
should be lubricated regularly every year depending on usage. (Tools used on heavy
duty jobs and tools exposed to heat may require more frequent lubrication.) This
lubrication should be attempted only by trained power tool repairperson's such as those
at Porter Cable service centers or in other qualified service personnel.
