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 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 deterio- ration. 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 ordering.
DRIVE WHEELS
Check front 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, check both front wheels.
1.Remove hubcaps, hairpin cotters 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 your nearest authorized service center.

•To keep your drive system working properly, the gear case and area around the drive should be kept clean and free of trash
•The gear case is filled 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.
