After cleaning your deck, restart the mower. Keep the engine and blade running fora minimum of two minutes, allowing the underside of the cutting deck to thoroughly dry

Blade Care

When removing the cutting blade for sharpening or replacement, protect your hands with a pair of heavy gloves or use a heavy rag to hold the blade.

Periodically inspect the blade adapter for cracks, especially if you strike a foreign object. Replace when necessary. Follow the steps below for blade service.

1. Allow the engine to run until itis out of fuel. Do not attempt to pour fuel from the engine. Disconnect spark plug wire. Refer to Engine Operator's Manual.

2. Turn mower on its side making sure that the air filter and the carburetor are facing up.

3. Remove the bolt and the blade bell support which hold the blade and the blade adapter to the engine crankshaft. See Figure 15.

4. Remove blade and adapter from the crankshaft.

5. Remove blade from the adapter for testing balance. Balance the blade on a round shaft screwdriver to check. Remove metal from the heavy side until it balances evenly. When sharpening the blade, follow the original angle of grind. Grind each cutting edge equally to keep the blade balanced.

An unbalanced blade will cause excessive vibration when rotating at high speeds. It may cause damage to mower and could break causing personal injury.

6. Lubricate the engine crankshaft and the inner surface of the blade adapter with light oil. Slide the blade adapter onto the engine crankshaft. Place the blade on the adapter such that the side of the blade marked “Grass Side” (or with part number) faces the ground when the mower is in the operating position. Make sure that the blade is aligned and seated on the blade adapter flanges. See Figure 15 inset.

7. Place blade bell support on the blade. Align notches on the blade bell support with small holes in blade.
8. Replace hex bolt and tighten hex bolt to torque: 450 in-Ib (min.), 600 in-Ib (max.). To ensure safe operation of your mower, periodically check the blade bolt for correct torque.

Preparing The Engine

For engines stored over 30 days:

  • To prevent gum from forming in fuel system or on carburetor parts, run engine until it stops from lack of fuel or add a gasoline additive to the gas in the tank. If you use a gas additive, run the engine for several minutes to circulate the additive through the carburetor.
  • An oil change is not required but if you desire to change the oil then change while the engine is warm.
  • Clean engine of surface debris.

Preparing The Lawn Mower
