To balance blade

•When sharpening the blade, follow original angle of grind as a guide. It is extremely important to grind off all edges equally to keep the blade balanced.

NOTE: An unbalanced blade will cause excessive vibration when rotating at high speeds and may cause damage to the mower and/or personal injury.

•Test the blade by balancing it on a round shaft screwdriver. See Figure 15.

•Remove metal from the heavy side until it balances evenly. Always remove blade from the adapter for the best test of balance.
