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 rear drive 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 area and must be cleaned to free drive wheels.

If necessary to clean the drive wheels, be sure to clean both rear wheels.

BLADE CARE

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

TO SHARPEN BLADE

NOTE: We do not recommend sharpening 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 fi le 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 damage or deterio- ration. Through normal use it will wear. If catcher needs replacing, replace only with approved replacement catcher shown in the Repair Parts section of this manual. Give the lawn mower model number when ordering.

Maintenance, repair, or replacement of the emission con- trol devices and systems, which are being done at the customers expense, may be performed by any non-road engine repair establishment or individual.Warranty repairs must be performed by an authorized engine manufacturer's service outlet.

LUBRICATION
