Blade Safety
A worn or damaged blade can break, and a piece of
the blade could be thrown toward you or bystanders,
resulting in serious personal injury or death.
•
Inspect the blades periodically for wear or damage.
•
Use care when checking the blades. Wrap the
blades or wear gloves, and use caution when
servicing the blades. Only replace or sharpen the
blades; never straighten or weld them.
•
Always inspect the machine to ensure that the
blades and blade bolts are not worn or damaged.
Replace worn or damaged blades and bolts in sets
to preserve balance.
•
On multi-bladed machines, take care as rotating 1
blade can cause other blades to rotate.
Servicing the Cutting
Blades
To ensure a superior quality of cut, keep the blades
sharp. For convenient sharpening and replacement,
keep extra blades on hand.
Before Inspecting or Servicing the
Blades
1.
Park the machine on a level surface, disengage
the PTO, and engage the parking brake.
2.
Shut off the engine, remove the key, and
disconnect the spark-plug wires from the spark
plugs.

Measure from a level surface to the cutting edge
of the blades at the same position as in step
above.
Note:
The difference between the dimensions
obtained in steps
and
must not exceed 3 mm
(1/8 inch).
Note:
If this dimension exceeds 3 mm
