Servicing the Cutting Blades

Service Interval: Yearly
Important: You will need a torque wrench to install the
blades properly. If you do not have a torque wrench or
are uncomfortable performing this procedure, contact
an Authorized Service Dealer.
Examine the blades whenever you run out of gasoline. If the
blades are damaged or cracked, replace them immediately. If
the blade edges are dull or nicked, have them sharpened and
balanced, or replace them.
DANGER
A worn or damaged blade can break, and a piece of
the blade could be thrown toward you or bystanders,
resulting in serious personal injury or death.
• Inspect the blades periodically for wear or
damage.
• Replace a worn or damaged blade.
Note: Maintain sharp blades throughout the cutting season,
because sharp blades cut cleanly without tearing or shredding
the grass blades.
