Troubleshooting Foam Row Marker
If you do not get foam:
1. Be sure the airline and liquid lines do not have a hole in them or are not pinched, and
remove air and liquid tubing at each foamhead and check for flow.
2. Be sure you have enough foam concentrate in the tank. Very hard water may require
a great amount of concentrate to produce good foam. Not having enough foam con-
centrate in the tank may make good foam, but may not make enough foam. Be sure
to use a high quality concentrate such as GOODMARK.
3. Check and clean the screen-strainer located in the tank.
4. Be sure the flow control valve is open.
5. If the foam mixture in the tank is several days old, it is possible that the solution is no
longer able to foam, or produces little foam. Drain tank, rinse, and start with a fresh
solution.
6.Check battery connections to be certain the positive and negative terminals are not
reversed.
Problem Solution
Not enough foam Add more foam concentrate to tank
Check for holes in airline
Check for pinched air or liquid lines
Clean screen-strainer/foamhead
Adjust liquid flow control valve
Wet foam Add more foam concentrate to tank
Clean screen-strainer/foamhead
Reduce liquid flow
Foam is surging Use less concentrate
Foam does not
last on the ground Add more foam concentrate to tank
Use a high quality foam concentrate like GOODMARK
Use collector heads
Blowing foam in
windy weather Use less concentrate to make wetter foam
Add more water to foam solution
Increase liquid flow
