POTENTIAL HAZARD
•
If you leave the key in the ignition switch, someone could start the engine.
WHAT CAN HAPPEN
•
Accidental starting of the engine could seriously injure you or other bystanders.
HOW TO AVOID THE HAZARD
•
Remove the key from the ignition switch and pull the wire(s) off the spark plug(s) before you
do any maintenance. Also push the wire(s) aside so it does not accidentally contact the spark
plug(s).
Cutting Blade
For 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 Blades
1. Remove the mower; refer to Removing the Mower,
page 11.
2. Inspect the cutting edges (Fig. 32). If the edges are not
sharp or have nicks, remove the blade(s) and sharpen
them; refer to Sharpening the Blade(s), page 18.
3. Inspect the blade(s), especially the curved area (Fig.
32). If you notice any damage, wear, or a slot forming
in this area (Fig. 32), immediately install a new blade.
