Just as your automobile

is made necessary

NORMAL use. Professional Air-Cooled Engine Service is as close as
your nearest Sears Roebuck and Co. (or Sears Canada, Inc.) Service

by Sears is a good idea to avoid
breakdowns

do it at the end of the season, then you're
ready for the next. We even prepare it for storage for you.
