Blade Care

•Periodically inspect the blade adapter for cracks, especially if you strike a foreign object. Replace when necessary.

WARNING: When removing the cutting blade for sharpening or replacement, protect hands by using heavy gloves or a rag to grasp the cutting blade.

•Remove the bolt and blade support or bell washer which hold the blade and adapter to the engine crankshaft. See Figure 13. Remove the blade and adapter from the crankshaft.
