Determine Tank Fill Level (FX60 Trailer Only)
Use these reference charts to help determine how full of various materials the vacuum tank can be without
overloading trailer. Exceeding the maximum fill level will overload the trailer.
Never exceed the trailer capacity. You can exceed the vacuum tank lifting capacity if you drain the tank
down to the lifting capacity before lifting tank.
To use these charts, first select the appropriate table based on trailer and vacuum tank size. Next find the
material being excavated. If the material being excavated is not listed, find a material with similar density.
Then, determine the maximum fill level based on the amount of water in the water tank.

IMPORTANT: For all materials, the vacuum tank should be no more than half full when lifting the tank.
