Balancing the cutting blade on your Ryobi electric walk-behind lawn mower

• Check the balance of the mower cutting blade after sharpening the blade. Replace the blade if it's damaged and can't be balanced.
• Clamp a nail or screwdriver with a round shank horizontally in a vice so the nail or screwdriver will support the weight of the blade.
• Place the center hold of the cutting blade over the nail or screwdriver's round shank.
• If either end of the blade rotates downward, file that end of the blade and recheck the balance.
• Continue to file the blade end until the blade rests horizontally and the end doesn't rotate downward.

How to sharpen the blade on your Ryobi electric walk-behind lawn mower

• Shut off the lawn mower and make sure the blade has stopped rotating. Remove the safety key and battery pack then remove the blade.
• Tightly secure the cutting blade in a vise.
• Wear work gloves to protect your hands and safety goggles to protect your eyes.
• Carefully file the cutting edges of the blade with a fine tooth file or sharpening stone. Sharpen the blade at the original cutting angle.
• Sharpen the cutting edges on both ends of the blade. File off equal amounts of the cutting blade edges from both ends so the blade remains balanced.
• Check blade balance and continuing filing until the blade is properly balanced.
• Reinstall the cutting blade on the lawn mower
