Sharpening the Blade
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. An unbalanced blade will cause excessive vibration when rotating at high speeds. It may cause damage to the mower, and it could break causing personal injury.
Balancing the Blade
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.
Reinstalling the Blade
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 of the blade 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. Be certain the blade is aligned with, and seated onto, the blade adapter flanges.
•Place blade bell support on blade. Make sure the notches on the blade bell support are aligned with the small hole in the blade and replace the hex bolt.
•Torque hex bolt to: 450 in. lbs. min., 600 in. lbs. max.
NOTE: To ensure safe operation of your unit, the blade bolt must be checked periodically for correct torque.
SECTION 9: OFF-SEASON STORAGE
The following steps should be taken to prepare lawn mower for storage.
•Clean and lubricate the mower thoroughly as described in the lubrication instructions.
•The use of a pressure washer or garden hose to clean your unit is NOT recommended. Using these may cause damage to electrical components, spindles, pulleys, bearings, or the engine. The use of water will result in shortened life and reduced serviceability.
•Refer to engine manual for correct engine storage instructions.
•Coat mower’s cutting blade with chassis grease to prevent rusting.
•Store mower in a dry, clean area. Do not store next to corrosive materials, such as fertilizer and rock salt.
