Servicing The Cutting Blade - Toro 30252 Operator's Manual

Servicing the Cutting Blade

To ensure a superior quality of cut, keep the blade sharp.
For convenient sharpening and replacement, you may
want to keep extra blades on hand.
Danger
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 Servicing the Blade
Park the machine on a level surface, disengage the blade
control (PTO), set the parking brake, stop the engine,
remove the key, and disconnect the spark plug wire from
the spark plug.
Inspecting the Blade
1. Inspect the cutting edges (Fig 20).
If the edges are not sharp or have nicks, remove and
sharpen the blade; refer to Sharpening the Blade, page
22.

Checking for a Bent Blade
1. Rotate the blade until the ends face forward and
backward (Fig. 21).
2. Measure at the C location (Fig. 21) from a level
surface to the cutting edge of the blade (Fig. 22). Note
this dimension.

3. Rotate the opposite end of the blade forward.
4. Measure from a level surface to the cutting edge of the
blade at the same position as in step 2.
5. The difference between the dimensions obtained in
steps 1 and 2 must not exceed 1/8 in (3 mm).
If this dimension exceeds 1/8 in. (3 mm), the blade is
bent and you must replace it.
Warning
A blade that is bent or damaged could break
apart and could seriously injure or kill you or
bystanders.
Always replace bent or damaged blade with a
new blade.
Never file or create sharp notches in the edges
or surfaces of blade.
Removing the Blade
Replace the blade if it hits a solid object, it is out of
balance, or it is bent. To ensure optimum performance and
continued safety conformance of the machine, use genuine
Toro replacement blades. Replacement blades made by
other manufacturers may result in non-conformance with
safety standards.
