When electric tools are used on liberglass boals,
sporls cars, wallboard, spackling compounds, or
plaster, it has been found that they are subject to ac-
celerated wear and possible premature failure. as
the chips and grindings are highly abrasivelo bear-
ings, brushes, commutator, etc. Consequently it is
not recommended that this tool be used for extend-
ed work on any fiberglass material, wallboard,
spackling compounds, or plaster.
Duringany use on
lhese materials, it is extremely important lhat the
lool is cleaned frequently by blowing with an air jet.
