Maintenance

Servicing the Cutting Blades

To ensure a superior quality of cut, keep the blades
sharp. For convenient sharpening and replacement, you
may want to keep extra blades on hand.
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.
Before Inspecting or Servicing the
Blades
Park the machine on a level surface, disengage the blade
control bail and set the parking brake. Turn the ignition
key to off. Remove the key and disconnect the spark
plug wire(s) from the spark plug(s).
Inspecting the Blades
Service Interval: Before each use or daily
1. Inspect the cutting edges (Figure 46). If the edges
are not sharp or have nicks, remove and sharpen the
blades. Refer to Sharpening the Blades.
