Note: Add a small amount of multipurpose grease to the bolt threads to avoid corrosion and galvanic action. WARNING Never mow with dull blades. Blades that are bent should be replaced. The cutting blades are sharp and can cause severe injury. Wrap the cutting surface of the blade with a rag to avoid injury. Figure 4-18 WARNING Avoid pinching injuries. Never place your fingers on the idler spring or between the belt and a pulley while removing the belt. 6. Route the new belt as shown in Figure 4-18.
