•Disconnect spark plug wire from spark plug.

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

To Sharpen Blade:

•The blade can be sharpened with a file or on a grinding wheel. Do not attempt to sharpen the blade while it is still on the mower.

•Follow the original angle of grind as a guide. Make sure that each cutting edge receives an equal amount of grinding to prevent an unbalanced blade.

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

•The blade can be tested by balancing it on a round shaft screwdriver. See Figure 13. Remove metal from the heavy side until it balances evenly. It is recommended that the blade always be removed from the adapter for the best test of balance.

•Before reassembling the blade and the blade adapter to the unit, lubricate the engine crankshaft and the inner surface of the blade adapter with light oil (or engine oil). Also lubricate the bolt holes and bolt.

•Install the blade adapter on the crankshaft with the “star” away from the engine. Refer to Figure 12. Place the blade with the side marked bottom (or with part number) facing away from the adapter.

•Align the blade bell support over the blade with the tabs in the holes of the blade and insert the hex bolt. Tighten the center bolt to 450 in. lbs. min., 600 in. lbs. max.

IMPORTANT:To ensure safe operation, all nuts and bolts must be checked periodically for correct tightness.
