Servicing The Cutting Blades - Toro Z Master Professional 5000 Series Operator's Manual

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.
WARNING
A worn or damaged blade can break, and a
piece of the blade could be thrown into the
operator's or bystanders' area, resulting in
serious personal injury or death.
• Inspect the blades 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
blades and set the parking brake. Turn the ignition
key to off. Remove the key, and disconnect the spark
plug wires from the spark plugs.
