Care should be taken to keep the blade balanced, An
unbalanced blade willcause excessive vibrationand even-
tual 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 bolt, pin, ora cone balancer. (When using a cone
balancer, follow the instructions supplied with bat-
ancer).
° Slide blade on to an unthreaded portionofthe steel bolt
or pin and hold the bolt or pin parallel with the ground.
If btade 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.
NOTE: Do not use a nail for balancing blade. The lobesof
the center hole may appear to be centered, but are not.
