10.Release the blade control bail. You should hear a “bang.” The blade should stop in three seconds.

11.Immediately push the lawn mower over the newspaper ball.

12.Stop the engine and wait for all moving parts to stop.

13.Walk around the lawn mower to check for the newspaper ball. If the ball did not go under the deck, repeat step 7 through 12.

14.Pull the lawn mower away from the newspaper. If the newspaper ball unravels or is shredded, the blade has not properly stopped, resulting in an unsafe operating condition. Contact an Authorized Service Dealer.

DANGER

POTENTIAL HAZARD

WHAT CAN HAPPEN

♦Contact with the blade could occur, causing serious injury.

HOW TO AVOID THE HAZARD

Test Using the Grass Bag:

1.Install the empty grass bag on the discharge tunnel.

2.Start the engine.

3.Squeeze the blade control bail against the handle.

4.Move the blade control lever to the full forward Latch position. The bag should begin to inflate, indicating that the blade is engaged and rotating.
