leaves, dirt, or other matter. If this debris is allowed to accumulate, it will invite rust and corrosion, and may prevent proper mulching, discharge, or bagging. The deck may be cleaned by tilting the mower and scraping clean with a suitable tool (make certain the spark plug wire is disconnected).
IMPORTANT: We do not recommend the use of a pressure washer or garden hose to clean your unit. The use of water will result in shorter life and less serviceability.
Cutting Blade
•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.
•Remove the bolt and the blade bell support which hold the blade and the blade adapter to the engine crankshaft. See Figure 13.
•Remove the blade and the adapter from the crankshaft.

WARNING: Periodically inspect the blade adapter for cracks, especially if you strike a foreign object. Replace when necessary.
•When sharpening the blade, follow the original angle of grind as a guide. It is extremely important that each cutting edge receives an equal amount of grinding to prevent an unbalanced blade.
WARNING: An unbalanced blade will cause excessive vibration when rotating at high speeds. It may damage the mower, and/ or cause personal injury.
•The blade can be tested by balancing it on a round shaft screwdriver. Remove metal from the heavy side until it balances evenly. It is recommended that the blade always be removed from the adapter when testing for balance. Before reinstalling the blade and the blade adapter to the unit, lubricate
the engine crankshaft and the inner surface of the blade adapter with light oil.
•Be sure to install the blade with the side marked “Bottom” (or with part number) facing the ground when the mower is in the operating position.
•Slide the blade adapter onto the engine crankshaft.
•Place the blade on the adapter.The blade has to be aligned and seated on the blade adapter flanges.
•Place blade bell support on blade. Make sure the notches on the blade bell support are aligned with small holes in the blade.
•Replace hex bolt and tighten hex bolt to torque: 450 in. lbs. min., 600 in. lbs. max.
NOTE: To ensure safe operation, the blade bolt must be checked periodically for correct torque.
Lubrication
Always stop engine and disconnect spark plug wire before cleaning, lubricating or doing any kind of service work on the lawn mower.
Blade Control
Lubricate the pivot points on the blade control handle at least once a season with light oil. The blade control must operate freely in both directions.
Wheels
Lubricate the wheels at least once a season with light oil (or motor oil). If the wheels are removed for any reason, lubricate the surface of the axle bolt and inner surface of the wheel with light oil.
Chute Deflector
Lubricate the torsion springs and pivot points on chute deflector using light oil. This will insure the deflector, which is a safety device, can always work properly.
Engine
Follow the engine manual for lubrication instructions.
Replacing Rear Flap
•To remove rear flap, cut off the flat end of the wire rod which secures it to the deck. See Figure 14.
•Attach the new flap and new rod to deck, bending the ends of the new rod over to secure to deck.
