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 Briggs and Stratton Power Products service dealer clean the cooling system (Figure 17) per recommended intervals (see “Maintenance Schedule” on page 15). Equally important is to keep top of engine free from debris. See “Generator Cleaning”.
