MAINTENANCE
GENERAL
Only the parts shown on parts list, page 23, are intended to
be repaired or replaced by the customer.
All other parts
represent an important part of the double insulation system
and should be serviced only by a qualified Sears service
technician.
Avoid using solvents when cleaning plastic parts.
Most
plastics are susceptible to various types of commercial
solvents and may be damaged by their use.
Use clean
cloths to remove dirt, carbon dust, etc.
When electric tools are used on fiberglass boats, sports
cars, wallboard, spackling compounds,
or plaster, it has
been found that they are subject to accelerated wear and
possible premature failure, as the fiberglass chips and
grindings
are highly
abrasive
to bearings,
brushes,
commutator, etc. Consequently, it is not recommended that
this tool be used for extended work on any fiberglass material,
wallboard, spackling compounds, or plaster.
During any
use on fiberglass it is extremely important that the tool is
cleaned frequently by blowing with an air jet.
