Grass Catcher; Engine - Craftsman 917.387440 Owner's Manual

TO SHARPEN BLADE
NOTE: We do not recommend
sharpening blade - but if you do, be sure
the blade is balanced.
Care should be taken to keep the blade
balanced. An unbalanced blade will
cause eventual damage to lawn mower or
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 or wall. Leave about one
inch of the straightnail exposed. Place
center hole of blade over the head of
the nail. If blade is balanced, it should
remain in a horizontalposition. If either
end of the blade moves downward,
sharpen the heavy end until the blade
is balanced.
