TO SHARPEN BLADE
: NOTE: We do not recommend sharpen-
ing blade - but ifyou 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 eP,gk_e.
The blade can be sharpened with a file
or on a gdnding wheel. Do not attempt
to sharpen while on the mower.
To check blade balance, ddve a nail
intoa 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 hodzontal position. If either
end of the blade moves downward,
sharpen the heavy end until the blade
is balanced.
