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.
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. Trying to
repair a damaged blade may result in discontinued

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.
On multi-bladed machines, take care as rotating 1
blade can cause other blades to rotate.
Park the machine on a level surface, disengage
the blade-control switch (PTO), and engage the
parking brake.
Shut off the engine, remove the key, and
disconnect the spark-plug wires from the spark
plugs.
Inspect the cutting edges
If the edges are not sharp or have nicks, remove
and sharpen the blade; refer to
Blades (page 44).
Inspect the blades, especially in the curved area.
If you notice any cracks, wear, or a slot forming
in this area, immediately install a new blade
