Cutting Blade
To assure a superior quality of cut, keep the blade(s)
sharp. For convenient sharpening and replacement,
you may want to have an extra blade(s).
POTENTIAL HAZARD
•
A blade that is worn or damaged could
break apart and pieces could be thrown at
bystanders or at you as you use the mower.
WHAT CAN HAPPEN
•
Pieces of blade that may be thrown could
seriously injure or kill you or bystanders.
HOW TO AVOID THE HAZARD
•
Periodically inspect the blade for wear and
damage. Immediately install a new blade if
it is worn or damaged.
Inspecting the Blade(s)
1.
Remove the mower; refer to Removing the
Mower, page 34.
2.
Inspect the cutting edges (Fig. 35). If the edges
are not sharp or have nicks, remove the blade(s)
and sharpen them; refer to Sharpening the
Blade(s), page 33.
3.
Inspect the blade(s), especially the curved area
(Fig. 35). If you notice any damage, wear, or a
slot forming in this area (Fig. 35), immediately
install a new blade.

Remove the mower; refer to Removing the
Mower, page 34.

Carefully tip the mower over.

Remove the bolt (5/8” wrench), curved washer,
retainer and blade (Fig. 36). A block of wood
may be wedged between the blade and the
mower to lock the blade when you are removing
the bolt.
