Note:
For the best performance, install a new blade
before the mowing season begins. During the year,
file down any small nicks to maintain the cutting edge.
DANGER
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 blade periodically for wear or
damage.
• Replace a worn or damaged blade.
Inspecting the Accelerator
Service Interval: Before each use or daily—Inspect
the accelerator for wear or damage.
Carefully examine the accelerator for excessive wear
(Figure
31). Because sand and abrasive material can
wear away the metal (especially in the area shown
as item 2 in
Figure
31), check the accelerator before
using the machine. If you notice that a tab on the
accelerator has been worn down to a sharp edge
or there is a crack, replace the accelerator; refer to
Removing the Blade (page

Sharpening the Blade
Service Interval: Every 50 hours—Sharpen or
replace the blade. Maintain it more
frequently if the edge dulls quickly in
rough or in sandy conditions.
File the top side of the blade to maintain its original
cutting angle
