Air Cooling System
Over time debris may accumulate in cylinder cooling
fins and cannot be observed without partial engine
disassembly. For this reason, we recommend you have
an authorized Sears service dealer clean the cooling
system per recommended intervals (see "Maintenance
Schedule" on page 14). Equally important is to keep top
of engine free from debris. See "Clean Debris".
Keep areas within heavy Jine cJear of debris.
Clean Combustion Chamber
We recommend you have an authorized Sears service
dealer remove combustion deposits from the cylinder,
cyJinder head, top of piston and around vaJves per
recommended intervals (see "Maintenance Schedule"
on page 14).
