1.Disconnect spark plug wire from spark plug and place wire where it cannot

come in contact with spark plug.

5.Remove blade and attaching hard- ware (bolt, lock washer and hardened washer).

NOTE: Remove the blade adapter and check the key inside hub of blade adapter. The key must be in good condi- tion to work properly. Replace adapter if damaged.

TO REPLACE BLADE

2.Position blade on the blade adapter aligning the two (2) holes in the blade with the raised lugs on the adapter.

3.Be sure the trailing edge of blade (opposite sharp edge) is up toward the engine.

TO SHARPEN BLADE

NOTE: We do not recommend sharpen- ing blade - but if you do, be sure the blade is balanced.

Care should be taken to keep the blade balanced. An unbalanced blade will

cause eventual damage to lawn mower or engine.

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