Operation
Using the Controls
Right boom switch
—activates the compressor,
generating a flow of foam to the right boom section.
Left boom switch
—activates the compressor,
generating a flow of foam to the left boom section.
Note:
You can drop the foam simultaneously from
both boom sections.
Sight gauge
—indicates the solution level in the tank.
It is located on the side of the tank.
Foam density adjustment valve
—controls the
consistency of the foam solution. Setting the valve
to Decreasing lowers the water content, allowing
the markers to hold its shape. Setting the valve to
Increasing creates a more watery marker.
Note:
On a windy day, a watery marker consistency
may be helpful.
Pressure relief valve
—when it is in the upright
position, it relieves the pressure in the foam solution
tank.
Filling the Tank and Adjusting
the Foam Density
1. Ensure that both the left and right boom switches
located on the console are in the Off position.
The contents of the foam marker tank are under
pressure. Loosening the fittings on the tank
could result in personal injury.
Flip the pressure relief valve into the Up
position.
2. Flip the pressure relief valve to the upright position
(Figure 32). Wait until all air has escaped.

Lid clamp
3. Pull up on the lid clamp, turn the lid 90 degrees, and
remove it from the tank.
4. Pour the proper amount water and foam concentrate
through the opening in the top of the tank according
to the manufacturer’s instructions.
Important:
Extreme pH levels
(hardness/softness) of the water will
affect the amount of foam concentrate needed.
5. Install the lid on the solution tank.
6. Ensure that the lid is positioned properly for a tight
seal and push down on the clamp lid.
7. Close the pressure relief valve.
8. For the initial operation, open the foam density
adjustment valve 1/8 to 1/4 turn (Figure 33).
