CILINDRO

1.Remueva la bujía.

2.Vacíe 29 ml (una onza) de aceite a través del agujero de la bujía en el cilindro.

3.Tire la manilla de arranque lentamente unas cuantas veces para distribuir el aceite.

4.Cambie por una bujía nueva.

OTROS

•No guarde la gasolina de una temporada a la otra.

•Cambie el envase de la gasolina si se emp- ieza a oxidar. La oxidación y/o la mugre en su gasolina producirán problemas.

•Si es posible, guarde su unidad en un recinto cerrado y cúbrala para protegerla contra el polvo y la mugre.

•Cubra su unidad con un forro protector adecuado que no retenga la humedad. No use plástico. El plástico no puede respirar, lo que permite la formación de condensación, lo que producirá la oxidación de su unidad.

IMPORTANTE: Nunca cubra la segadora mien- tras el motor y las areas de escape to davia estan calientes.

PRECAUCIÓN: Nunca almacene la sega- dora con gasolina en el estanque dentro de un edificio en donde los gases pueden alcanzar una llama expuesta o una chispa. Permita que se enfríe el motor antes de alma-cenarla en algún recinto cerrado.

LAWN MOWER

Always observe safety rules when per- forming 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.

DRIVE WHEELS

Check rear drive wheels each time you mow to be sure they move freely. The wheels not turning freely means trash, grass cuttings, etc., may be inside the drive wheel and dust cover area and must be cleaned out to free drive wheels.

If necessary to clean the drive wheels, check both rear wheels.

BLADE CARE

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

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. lbs. / 47-54 N-m.

IMPORTANT: Blade bolt is heat treated. If bolt needs replacing, replace only with approved bolt shown in the Repair Parts section of this manual.

CAUTION: Use only a replacement blade approved by the manufacturer of your mower. Using a blade not approved by the manufacturer of your mower is hazardous, could damage your mower and void your warranty.

TO REMOVE BLADE

1.Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with 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 hardware (bolt, lock washer, hardened washer).

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

TO REPLACE BLADE

1.Position the blade adapter on the en- gine 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 (oppo- site sharp edge) is up toward the engine.

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

NOTE: We do not recommend sharp- ening blade - but if you do, be sure the blade is 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.

GRASS CATCHER

•The grass catcher may be hosed with water, but must be dry when used.

•Check your grass catcher often for dam- age or deterioration. Through normal use it will wear. If catcher needs replac- ing, replace only with approved replace- ment catcher shown in the Repair Parts section of this manual. Give the lawn mower model number when ordering.

GEAR CASE

•To keep your drive system working properly, the gear case and area around the drive should be kept clean and free of trash build-up. Clean under the drive cover twice a season.

•The gear case is fi lled with lubricant to the proper level at the factory. The only time the lubricant needs attention is if service has been performed on the gear case.
