Maintenance
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 8.
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 15.
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.

Removing the Blade
1.
Remove the mower; refer to Removing the
Mower, page 8.
2.
Carefully tip the mower over.
3.
Remove the nut, flat washer, blade and washer
(Fig. 24). A block of wood may be wedged
between the blade and the mower to lock the
blade when you are removing the bolt.

Inspect all parts. If a defect or damage is noticed,
install new parts.
