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 AV
OID 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 9.
2. Inspect the cutting edges (Fig. 23). If the edges
are not sharp or have nicks, remove the blade(s)
and sharpen them; refer to Sharpening the
Blade(s), page 17.
3. Inspect the blade(s), especially the curved area
(Fig. 23). If you notice any damage, wear, or a
slot forming in this area (Fig. 23), immediately
install a new blade.
