Over time debris may accumulate in cylinder cooling fins and
cannot be observed without partial engine disassembly. For
this reason, we recommend you have a qualified Sears
service dealer clean the cooling system per recommended
intervals (see MaintenanceSchedule). Equally important is to
keep top of engine free from debris. See CleanDebris.
Keep areas within heavy line clear of debris.
