BLADE BRAKE CLUTCH - ALERT SPRING
The mower is equipped with a spring device that can alert the
operator of a malfunction of the spring that engages the blade
brake. The spring, 201339-5, will normally apply the pres-
sure to the blade brake system when the operator releases
the upper control bar/operator’s presence control at the upper
handle. In the event of a malfunction of the spring (201339-5)
the lawn mower blade might not stop completely. Therefore
always follow all the instructions and perform the BBC Function
Test as described on Page 10 before each use.
The alert spring system (1) on the Bravo 25 can alert the
operator if the spring 201339-5 malfunctions (breaks).
A fl at spring (1) - bright red - is located under the mower deck.
It is attached to one of the screws for the spindle.
The alert spring is pulled away from the blade of the mower by
means of the wire hook (2) that is attached to the Blade Brake
Spring 201339-5. The wire hook is visible on the right side of
the engine.
