GENERAL
EXTENSION
Only the parts shownon parts list, page 13. are intended
to be repaired or replaced by the customer.All other parts
represent an importantpart of the double insulationsystem
and shouldbe serviced only at a qualified service center.
The use of any extensioncord will cause some loss of
power. To keep the loss to a minimumand to preventtool
overheating,followthe recommendedcord sizes on the
chart below. When tool is used outdoors,use only
extension cords suitablefor outdooruse and so marked.
Extensioncordsare available at Sears Retail Stores.
Avoid usingsolventswhen cleaning plasticparts. Most
plasticsare susceptibleto various types of commercial

WARNING: Do not at any time let brake fluids,
gasoline, petroleum-based products,penetrating
oils, etc. come in contact with plasticparts. They
containchemicals that can damage, weaken, or
destroy plastic.
When electric tools are used on fiberglass boats, sports
cars, wallboard, spacklingcompounds,or plaster, it has
been found that they are subjectto acceleratedwear and
possiblepremature failure, as the fiberglass chipsand
grindings are highlyabrasive to beatings, brushes,
commutators,etc. Consequently it is not recommended
that this tool be used for extended work on any fiberglass
material, wallboard,spacklingcompounds,or plaster.
During any use on these materials, it is extremely
importantthat the tool is cleaned frequently by blowing
with an air jet.
