TO SHARPEN BLADE
NOTE: We do notrecommend sharpen-
ing blade - but ifyou do, be sure the
blade is balanced.
Care shouldbe 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 gdnding wheel. Do not attempt
to sharpen while on the mower.
To check blade balance, ddve 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.

The grass catcher may be hosed with
water, but must be dry when used.
Check your grass catcher often for

replacing,replace only with a manufac-
turer approved replacement catcher.
