Using Your Lawn Mower
IMPORTANT:
Be sure the lawn is clear of stones, sticks, wire, or other objects which could damage the lawn mower
or the engine. Such objects could be accidently thrown by the mower in any direction and cause serious personal
injury to the operator and others.
WARNING: The operation of any lawn mower can result in foreign objects being thrown into the eyes,
which can damage your eyes severely. Always wear safety glasses while operating the mower, or while
performing any adjustments or repairs on it.
WARNING: Be sure no one other than the operator is standing near the lawn mower while starting
engine or operating mower. Never run engine indoors or in enclosed, poorly ventilated areas. Engine
exhaust contains carbon monoxide, an odorless and deadly gas. Keep hands, feet, hair and loose clothing
away from any moving parts on engine and lawn mower.
WARNING: THIS CONTROL MECHANISM IS A SAFETY DEVICE. NEVER ATTEMPT TO BYPASS
ITS OPERATION.
WARNING: If you strike a foreign object, stop the engine. Remove wire from the spark plug, thoroughly
inspect the mower for any damage, and repair the damage before restarting and operating the mower.
Extensive vibration of the mower during operation is an indication of damage. The unit should be promptly
inspected and repaired.
