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 steps 6 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.
To check for a problem with the BBC system before it
affects its normal operation, you can perform the Special
Test that follows.
Special Test
1. Follow steps 1 through 7 from the Normal Test on
page 11.
2. Move the blade control bail down to its lowest position
(Position B in Fig. 17).
3. Bring the blade control bail up into the middle position
about 5 inches (12.7 cm) below the handle cross bar
(Position C in Fig. 18).

Note: This intermediate position (C) is not the normal
operating position of the blade control bail. However, it
helps to detect a sticking BBC system early enough to
prevent an unsafe condition later.
