TO REPLACE BLADE (See figure 9):
Use only a Sears authorized replacement blade to get
the best cutting results. Do not use substitutes.
NOTE: All parts must be assembled in the exact order
as shown.
• Fit blade in adapter. Be sure trailing edge of blade
is up towards motor.
• Tighten blade nut securely (30-35 ft. Ibs. torque).
• Re-insert cotter pin and bend ends to secure.
NOTE: If after tightening nut, the slot in nut is not
aligned with hole in shaft, tighten nut just enough to
allow cotter pin insertion.
WARNING: A LOOSE BLADE CAN BE
DANGEROUS.
TO SHARPEN BLADE
NOTE: We do not recommend sharpening the blade--
but if you do, be sure blade is balanced.
• The blade can be sharpened with afile or on a grind-
ing wheel. Do not attempt to sharpen while on the
mower.
Care should be taken to keep the blade balanced.
An unbalanced blade will cause excessive vibration
when running and eventual damage to mower and
motor.
To check blade balance, drive a nail into a beam or
wall. Leave about one inch of straight nail exposed.
Place center hole of blade over the head ofthe nail.
If blade is balanced, itshould remain in a horizontal
position.If either end of the blade moves downward,
blade is not balanced. Sharpen the heavy end until
the blade is balanced.
