Push Mower

Never take a running mower over gravel, stones, or hard objects such as pipes, rocks, or sidewalks. 

Never pull, always push the mower forward. Plan to mow across slopes since the feet will less likely get caught in the blade. Keep hands and feet clear of the blade housing and the discharge chute. 

Ensure the correct positioning of safety devices including the rear shield, grass chute deflector, handle up stops, and dead man control. Ensure dryness of the grass before beginning. Disconnect the spark plug wire before attempting service, adjustment, or repair of the mower.
