Obstacles
Use the side of the mower to cut close to large obstacles, such as fences or walls.
If a blade hits something or the mower starts to vibrate, stop the engine immediately,
disconnect the spark plug cap, and check for damage . Striking objects may
damage the blades, bend the crankshaft, and/or break the mower deck or other components.
Vibration usually indicates serious trouble.
WARNING
A worn, cracked, or damaged blade can break, and pieces of the damaged blade can become
●
dangerous projectiles. Thrown objects can cause serious injury. Inspect the blades regularly,
and do not operate the mower with a worn or damaged blade.
Gravel and Loose Objects
Gravel, loose stones, and landscaping material can be picked up by the mower and thrown many
feet with enough force to cause serious personal injury and/or property damage.
prevent potential injury from thrown objects by releasing the blade control lever to stop the blades
before reaching areas with gravel, loose stones, or landscaping material.
