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

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

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

Use a wood block between blade and mower housing to prevent blade from turning when removing blade bolt.

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

Remove blade bolt by turning counter-

clockwise. Use a 9/16" box or open- end wrench.

Remove blade and attaching hard- ware.

TO REPLACE BLADE

Position the blade adapter on the engine crankshaft. Be sure the spacer is in the adaptor and key in shaft and adaptor keyway are aligned.

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

Install the blade bolt with washers into blade adapter and crankshaft.

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 HEATTREATED.

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.
