NOTE: We do not recommend sharpening
blade - but if you do, be sure the blade is
balanced.
TO SHARPEN BLADE
Care should be taken to keep the blade
balanced. An unbalanced blade wilt cause
eventual damage to lawn mower or engine.
o 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, tf either end of the blade moves
downward, sharpen the heavy end until the
blade is balanced.

NOTE: Although multi_viscosity oils
(5W30, 10W30 etc.) improve starting in
cold weather, these multi_viscosity oils
will result in increased oil consumption
when used above 32°F_ Check your
engine oil level more frequently to avoid
possible engine damage from running low
on oil.
Change the oil after every 25 hours of opera-
tion or at least once a year if the lawn mower
