Cutting Blade
WARNING: When removing the cutting blade for sharpening or replacement, protect hands by using heavy gloves or a rag to grasp the cutting blade.
To remove blade
•Remove the bolt and blade bell support which hold the blade and adapter to the engine crankshaft. See Figure 11. Remove the blade and the adapter from the crankshaft.
WARNING: Periodically inspect the blade adapter for cracks, especially if you strike a foreign object. Replace when necessary.
•When sharpening the blade, follow the original angle of grind as a guide. It is extremely important that each cutting edge receives an equal amount of grinding to prevent an unbalanced blade. An unbalanced blade will cause excessive vibration when rotating at high speeds, may damage the mower and/or cause personal injury.
•The blade can be tested by balancing it on a round shaft screwdriver. Remove metal from the heavy side until it balances evenly. It is recommended that the blade always be removed from the adapter for the best test of balance
