Servicing the 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 fuel. 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.
Important:
Always wear padded gloves when
working with the blade.
DANGER
g016491
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.
