TO REMOVE BLADE
1. Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with plug.
2. Turn lawn mower on its side. Make
sure air filter and carburetor are up.
3. Use a wood block between blade and
mower housing to prevent blade from
turning when removing blade bolt.
NOTE: Protect your hands with gloves
and/or wrap blade with heavy cloth.
4. Remove blade bolt by turning counter-
clockwise.
5. Remove blade and attaching hardware
(bolt, lock washer, hardened washer).
NOTE: Remove the blade adapter and
check the key inside hub of blade adapter.
The key must be in good condition to work
properly. Replace adapter if damaged.

gine crankshaft. Be sure key in adapter

TO SHARPEN BLADE
Crankshaft
i
Crankshaft
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 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.
