Replacing the Blade
Service Interval:

the blade properly

wrench or are uncomfortable performing this
procedure, contact an Authorized Service Dealer.
Examine the blade whenever you run out of gasoline. If
the blade is damaged or cracked, replace it immediately.
If the blade edge is dull or nicked, have it sharpened and
balanced, or replace it.

The blade is sharp; contacting the blade can result
