MAINTENANCE

LAWN MOWER

Always observe safety rules when performing any main- tenance.

TIRES

•Keep tires free of gasoline, oil, or insect control chem- icals which can harm rubber.

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

DRIVE WHEELS

Check wheels each time before you mow to be sure they move freely.

The wheels not turning freely means trash, grass cuttings, etc. are in the drive wheel or dust cover area and must be cleaned to free drive wheels. If necessary to clean the drive wheels, be sure to clean all wheels.

1.Remove hubcaps, locknuts and washers.

2.Remove wheels from wheel adjusters.

3.Remove any trash or grass cuttings from inside the dust cover, pinion and/or drive wheel gear teeth.

4.Put wheels back in place.

NOTE: If after cleaning, the drive wheels do not turn freely, contact a qualiﬁed service center.

BLADE CARE

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

CAUTION: Useonlyareplacementblade 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.

2.Install debris shield.

3.Position blade on the blade adapter.

IMPORTANT: TO ENSURE PROPER ASSEMBLY, CENTER HOLE IN BLADE MUST ALIGN WITH STAR ON BLADE ADAPTER.

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

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

6.Use block of wood between blade and lawn mower hous- ing and tighten the blade bolt, turning clockwise.

•The recommended tightening torque is 35–40 ft. lbs.

NOTE: We do not recommend sharpening blade - but if you do, be sure the blade is balanced. An unbalanced blade will cause eventual damage to lawn mower or engine.
