TIRES
• Maintain proper air pressure in all tires
(See =PRODUCT SPECIFICATIONS"
section of this manual).
• Keep tires free of gasoline, oil, or insect
control chemicals which can harm
rubber.
• Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may
cause tire damage.
NOTE: To sea[ tire punctures and prevent
flat tires due to slow leaks, tire sealant
may be purchased from your local parts
dealer."13resealant also prevents tire dry

TO SHARPEN BLADE
NOTE: We do not recommend sharpen-
ing blade - but if youde, be sure the
blade is balanced.
Care should be taken to keep the blade
balanced. An unbalanced blade will
cause excessive vibration and eventual
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, you will need
a 5/8' diameter steel bolt, pin, or a cone
balancer. (When using a cone bal-
ancer, follow the instructions supplied
with balancer.)
NOTE: Do not use a nail for balancing
blade. The lobes of the center hole may
appear to be centered, but are not.
• Slide blade on to an untbreaded
portion of the steel bolt or pin and hold
the belt or pin parallel with the ground.
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.
