Grass Catcher - Craftsman EZ3 917.387151 Owner's Manual

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 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
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.
GRASS CATCHER
• The grass catcher may be hosed with
water, but must be dry when used.
• Check your grass catcher often for damage
or deterioration. Through normal use it will
wear. If catcher needs replacing, replace
only with a manufacturer approved
replacement catcher. Give the lawn mower
model number when ordering.

possible engine damage from running low
on oil.

tion or at least once a year if the lawn mower
