Adjusting the Nautilus Reverse Sensing Switch
To prevent squeegee damage a reverse sensing switch
causes the rear squeegee to raise whenever the vehicle
moves in reverse. When the vehicle is stopped or resumes
forward motion the rear squeegee automatically lowers
back to the fl oor.
The neutral sensing switch is a whisker-type switch located
below the directional control pedal. The switch is activated
by the directional control pedal arm. (See Fig. 3)
