Fuel filter (Fig. 34) Remove the fuel filter from the fuel tank and thoroughly wash it in solvent. After that, push the filter into the tank completely. NOTE If the filter is hard due to dust and dirt, replace it. Chain oil filter (Fig. 35) Remove the oil filter and thoroughly wash it in solvent. Cleaning the cylinder fins (Fig. 36) When wood chips are caught between cylinder fins (38), the engine may overheat, resulting in lower output. To avoid this, always keep cylinder fins and fan case clean. Every 100 operating hours, or once a year (more often if conditions require), clean fins and external surfaces of engine of dust, dirt and oil deposits which can contribute to improper cooling. Cleaning the muffler (Fig. 37) Remove the muffler and spark arrestor, if so equipped, and clean out any excess carbon from the exhaust port or muffler inlet every 100 hours of operation. For long-term storage Drain all fuel from the fuel tank. Start and let engine run until it stops. Repair any damage which has resulted from use. Clean the unit with a clean rag, or the use of high pressure air hose. Put a few drops of two-cycle engine oil into the cylinder through the spark plug hole, and spin the engine over several times to distribute oil. Cover the unit and store it in a dry area.
