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 a qualified
Yardfoce service dealer clean the cooling system per
recommended intervals (see Maintenance Schedule).
Equally important is to keep top of engine free from debris.
