Figure 4-2 Engine A list of key engine maintenance jobs required for good performance by the mower is given below. Follow the Engine Operator's Manual for a detailed list of maintenance intervals and instructions. • Maintain oil level as instructed in the Engine Operator's Manual. • Service air cleaner once a season under normal conditions. Clean every few hours under extremely dusty conditions. Poor engine performance and flooding usually indicates that the air cleaner should be serviced. To service the air cleaner, refer to the engine manual. • Clean spark plug and reset the gap once a season. Spark plug replacement is recommended at the start of each mowing season. Check Engine Operator's Manual for correct plug type and gap specifications. • Clean engine regularly with a cloth or brush. Keep the top of the engine clean to permit proper air circulation. Remove all grass, dirt, and combustible debris from muffler area. • Engines stored between 30 and 90 days need to be treated with a gasoline stabilizer to prevent deterioration and gum from forming in fuel system or on essential carburetor parts.
