Servicing the Blades
Service Interval: Before each use or daily
To ensure a superior quality of cut, keep the blades
sharp. For convenient sharpening and replacement,
keep extra blades.
A worn or damaged blade can break and a piece
of the blade could be thrown into the operator's
or bystander's area, resulting in serious personal
injury or death.
• Inspect the blade periodically for wear or
damage.
• Replace a worn or damaged blade.
Inspecting the Blades
1. Remove the mower; refer to Removing the Mower.
2. Inspect the cutting edges (Figure 33). If the edges
are not sharp or have nicks, remove the blades and
sharpen them; refer to Sharpening the Blades.

new blade.
Removing the Blades
