Cutting Blade Service
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.
Warning
Before Inspecting or Servicing the
Blades
Park the machine on a level surface, disengage the blade
control (PTO) and chock or block tires. Turn the ignition
key to “OFF” to stop the engine. Remove the key and
disconnect the spark plug wire(s) from the spark plug(s).
Inspecting the Blades
1. Inspect the cutting edges (Fig 46). If the edges are not
sharp or have nicks, remove and sharpen the blades.
Refer to Sharpening the Blades on page 39.
2. Inspect the blades, especially the curved area (Fig. 46).
If you notice any damage, wear, or a slot forming in
this area (item 3 in Fig. 46), immediately install a new
blade.
