GENERAL
Just as your automobile needs professional mechanical maintenance
from time to time, so does your Craftsman engine. Replacement of the
spark plug and air cleaner is made necessary by NORMAL use.
Professional Air-Cooled Engine Service is as close as your nearest
Sears Roebuck and Co. (or Sears Canada, Inc.) Service Center.
A yearly check-up or tune-up by Sears is a good idea to avoid
breakdowns or delay.., do it at the end of the season, then you' re ready
for the next. We even prepare it for storage for you.
