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 excessive vibration and eventual
damage to mower and 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, you will need
a 5/8" diameter steel belt, pin, or a cone
balancer. (When using a cone bal-
ancer, follow the instructionssupplied
with balancer.)
NOTE: Do not use a nail for balancing
blade. The lobes of the center hole may
appear to be centered, but are not.
Slide blade on to an unthreeded
portion of the steel boltor pin and hold
the belt or pin parallel with the ground.
If blade is balanced, it should remain in
a hedzontal position. If either end of
the blade moves downward, sharpen
the heavy end untilthe blade is
balanced.
