TESTING THE SEAT SWITCH
Make sure the safety seat switch is operational prior to
using the float each day.
1. With the engine running, depress the foot pedal to start
turning the rotors.
2. Rise from the operator’s seat and observe the rotors:
a. If the engine continues to run but the rotors
have stopped turning, the seat switch is working
properly.
b. If the rotors continue to turn, the seat switch is not
working properly. Stop the engine immediately and
correct the problem.
WARNING
NEVER
disable or disconnect the seat switch. It is
provided for operator safety. Injury may result if it is
disabled, disconnected or improperly maintained.
