Foamer Operation
To operate the foam marking system, locate the toggle
switch on the hydrostat control handle (fig. 5.43). It controls a
pair of valves on the pressurized stainless steel foam tank (fig.
5.42) which force foam to the foam drop tubes on the end of
each outer boom.
Push the toggle switch to the left if foam is desired from the
left boom tip. Push the toggle switch to the right if foam is desired
from the right boom tip. Return the toggle switch to the middle
position if no foam is desired.
System pressure is indicated by a pressure gauge on the
regulator which is mounted next to the foam tank (fig. 5.44). To
adjust the air pressure in the foam tank, turn the knob on the
regulator clockwise for more pressure, and counterclockwise for
less pressure. To correctly decrease the pressure in the foam
tank, you must first open either the left or right foam valve for a
moment to relieve system pressure. Then adjust regulator
accordingly. For maintenance of the foam marker system see
page 99.
