How to Install: 1. Drain gasoline from tank. Leaking fuel may cause a fire resulting in personal injury. 2. Turn mower on side (Note: To keep gas and oil from clogging air filter, make sure air filter side is up and muffle side is down). Remove center bolt holding old blade and adapter on crankshaft. Retain bolt and lock washer for re-use. 3. Remove old blade and adapter assembly from crankshaft (Refer to operator's manual). Retain all hardware for use. 4. Clean old grass from underside of deck. 5. Crimp first! For best results, crimp the nylon dethatching line before inserting the blade. 6. Use care when attaching new blade. Contact with sharp edges could cause injury. Wear gloves and wrap sharp cutting edges with rags. 7. Identify the mounting configuration for your mower (See illustration panels). From the enclosed hardware kit, select the proper adapter bracket. Select the proper adapter washer (Same shape as center hole of new blade). 8. Select the proper flat washer (Same size as center hole on old blade) and place over adapter to prevent it from dropping out of blade, as shown. 9. Place the blade assembly on the end of the crankshaft, and secure it with the original blade bold. Tighten the bolt securely, per the requirements in your operator's manual. 10. Rotate blade to be sure it clears mower deck assembly. 11. Return mower to mowing position. Replace spark plug and reconnect spark plug wire. Add gasoline to engine. Mower is ready to operate.
