BLADE CARE
For best results, mower blade must be
kept sharp. Re place bent or dam aged
blades.
TO REMOVE BLADE
1. Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with spark plug.
2. Turn lawn mower on its side. Make
sure air fi lter and carburetor are up.
3. Use a wood block between blade and
mower hous ing to prevent blade from
turning when re mov ing 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 hard-
ware (bolt, lock wash er and hardened
wash er).
NOTE: Remove the blade adapter and
check the key inside hub of blade adapter.
The key must be in good con di tion to work
properly. Replace adapter if damaged.

1. Position the blade adapter on the en-
gine crank shaft. Be sure key in adapter
and crankshaft keyway are aligned.

TO SHARPEN BLADE
NOTE: We do not recommend sharp en ing
blade - but if you do, be sure the blade is
balanced.
Care should be taken to keep the blade
balanced. An un bal anced blade will
cause eventual damage to lawn mower or
engine.
• The blade can be sharp ened with a fi le
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 ex posed. 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.
