Obstacles
Use the side of the mower to cut close to obstacles, such as fences or
walls. Release the drive clutch lever to disengage the drive when
mowing around trees and other obstacles. Push the mower around
obstacles for better directional control. Be careful when mowing over
obstacles embedded in the lawn, such as sprinkler heads, paving,
edging, etc. Avoid anything sticking up above the surface of the lawn.
If the blade hits something, or if the mower starts to vibrate, stop the
engine immediately, disconnect the spark plug cap, and check for
damage (page 31). Striking objects may damage the blade, bend the
crankshaft, and/or break the mower deck or other components.
Vibration usually indicates serious trouble.
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 blade(s) regularly, and do not operate
the mower with a worn or damaged blade.
The Distributor's Limited Warranty (page 61) does not cover parts
damaged by accident or collision.
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. The best way to prevent
potential injury from thrown objects is to release the flywheel brake
lever to stop the blade before reaching areas with gravel, loose stones,
or landscaping material.
