TIRES
• Maintain proper air pressure in aIl tires (See "PROD-
UCT SPECIFICATIONS" on page 3 of this manual)
• Keep tiresfree of gasoline, oil, or insect control chemi-
cals which can harm rubber.
Avoid stumps, stones, deep ruts, sharp obiects and
other hazards that may cause tire damage.
BLADE CARE
For best results mower blades must be kept sharp. The
blades can be sharpened with a file or on a grinding wheel.
We suggest they be sharpened or replaced after every 25
hours of mowing Check blades more often if mowing in
sandy conditions
• Do not attempt to sharpen blades while they are on the
mower,
• Replace bent or damaged blades
BLADE REMOVAL (See Fig. 10)
• Raise mower to highest position to aflow access to
blades
• Remove hex bolt, lockwasher and fiat washer securing

TO SHARPEN BLADE (See Fig. '11)
Care should be taken to keep the blade balanced. An
unbalanced blade will cause excessive vibration and even-
tua! damage to 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 orwaII,
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.
