Adjusting Blade Brake Cable
Whenever you install a new blade brake cable assembly or

Warning
Overtightening the blade brake cable can cause
the blade brake to fail to stop a rotating blade
when you release the blade control bail. A rotating
blade can cause serious personal injury.
• Check the blade brake each time you adjust the
brake cable to ensure that the brake stops the
blade in three seconds or less.
• If the blade does not stop rotating in three
seconds or less, bring the lawn mower to an
Authorized Service Dealer for repair.
