®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.

case,

oIf lubricant is required, use only Texaco Starplex Pre- mium Grease, part no, 750355. Do not substitute.

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.
