LAWN MOWER

Always observe safety rules when performing any maintenance.

TIRES

Keep tires free of gasoline, oil, or insect control chemicals which can harm rubber.

Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage.

BLADE CARE

For best results, mower blade must be kept sharp. Replace bent or damaged blades.

TO REMOVE BLADE

1.Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug.

2.Turn lawn mower on its side. Make sure air filter and carburetor are up.

3.Use a wood block between blade and

mower housing to prevent blade from turning when removing blade bolt.

NOTE: Protect your hands with gloves and/or wrap blade with heavy cloth.

4.Remove blade bolt by turning counter- clockwise.

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

1.Position the blade adapter on the engine crankshaft. Be sure key in adapter and crankshaft keyway are aligned.

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.

4.Install the blade bolt with the lock washer and hardened washer into blade adapter and crankshaft.

5.Use block of wood between blade and lawn mower housing and tighten the

blade bolt, turning clockwise.

The recommended tightening torque is 35-40 ft. Ibs.

IMPORTANT: Blade bolt is grade 8 heat treated.

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.

To check blade balance, drive a nail into a beam or wall. Leave about one inch of the straight nail exposed. Place center hole of blade over the head of the nail. If blade is balanced, it should

remain in a horizontal position. If either end of the blade moves downward,

sharpen the heavy end until the blade is balanced.
