Servicing The Cutting Blades - Toro 30193 Operator's Manual

Someone could accidently start the engine and seriously injure you or other bystanders.
Disconnect the wire from the spark plug(s) before you do any maintenance. Set the wire aside so
that it does not accidentally contact the spark plug.

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
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 (PTO) and set the parking brake.
Inspecting the Blades
1. Inspect the cutting edges (Fig 24). If the edges are not
sharp or have nicks, remove and sharpen the blades.
Refer to Sharpening the Blades on page 25.
2. Inspect the blades, especially the curved area (Fig. 24).
If you notice any damage, wear, or a slot forming in this
area (item 3 in Fig. 24), immediately install a new
blade.
Caution
1. Cutting Edge
2. Curved Area
Checking for Bent Blades
1. Rotate the blades until the ends face forward and
backward (Fig. 25). Measure from a level surface to the
cutting edge of the blades (Fig. 26). Note this
dimension.
