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 for sharpness and any wear or damage whenever you run out of gasoline; refer to Inspecting the Blades (page 21). If the blade edge
is dull or nicked, have it sharpened or replace it. If the blade is worn, bent, damaged or cracked, replace it immediately with a genuine Toro replacement blade.
DANGER
A worn or damaged blade can break, and a piece of the blade could be thrown toward the operator or a bystander, 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. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease.
Preparing to Service the Cutting Blades
1.Lock the handle in the vertical position (Figure 41); refer to Adjusting the Handle Height (page 10).

2.Tip the machine onto its side, with the air filter up in the air, until the upper handle rests on the ground.
WARNING
The blades are sharp; contacting a blade could result in serious personal injury.
•Disconnect the wire from the spark plug.
•Wear gloves when servicing the blade.

1.Inspect the cutting edges (Figure 42). If the edges are not sharp or have nicks, remove the blades and have them sharpened or replace them.
2.Inspect the blades themselves, especially the curved area (Figure 42). If you notice any damage, wear, or a slot forming in this area (Figure 42), immediately replace it with a new blade.
