TO SHARPEN BLADE
Care should be taken to keep the blade balanced. An unbal- ancedbladewillcauseexcessivevibrationandeventualdamage to lawn mower and 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 damage or deterioration. Through normal use it will wear. If catcher needs replacing, replace only with a manufacturer approved replacement catcher. Give the lawn mower model number when order- ing.
