3.3.8 Adjusting the Cutting Height
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.
POTENTIAL HAZARD
♦ If the blade brake clutch system is inoperative, the
blade will continue to rotate when you release the blade
control bail.
WHAT CAN HAPPEN
♦ Contact with the blade could occur, causing serious
injury.
HOW TO AVOID THE HAZARD
♦ Check the BBC operation before each use.
♦ Never use the BBC-equipped lawn mower with an
inoperative safety system.
♦ Take your lawn mower to an Authorized Service Dealer
for repair if the safety system fails to operate properly.
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.
5. Release the blade control bail. If the bag does not immediately deflate, it
indicates that the blade is still rotating. The blade brake clutch mechanism
may deteriorating, and, if ignored could result in an unsafe operating
condition. Have the lawn mower inspected and serviced by an Authorized
Service Dealer.
