How to change your Ryobi Lawn Mower Blade?

Important: Always wear protective gloves and ensure the mower is completely powered off before performing any maintenance.

Step 1: Power Down the Mower
Remove the isolator/safety key and disconnect the battery packs from the mower to ensure complete power isolation.

Step 2: Position the Mower
Carefully tilt the mower onto its side, ensuring the blade is in a vertical position for safe access.

Step 3: Clean the Blade Area
Use a soft cloth to remove any dirt, grass, or debris around the blade area before beginning the replacement.

Step 4: Secure the Blade for Removal
Insert a wooden block (or wood chuck) between the blade and the cutting deck to prevent the blade from rotating.

Step 5: Remove the Blade Assembly
Using a 15 mm spanner, loosen the blade nut.
Detach and remove the blade nut, spacer, blade insulator, and the blade itself.

Step 6: Install the New Blade
Align the new blade with the designated cut-outs on the blade mount.

Step 7: Reassemble Blade Components
Reinstall the blade insulator and spacer in their correct positions.

Step 8: Secure the Blade
Once again, insert a wooden block to prevent the blade from rotating.
Tighten the blade nut using a 15 mm spanner, ensuring the blade bolt is secured.
