6-48 Rosco Maximizer 2B Asphalt Distributor
Operation
For example:
Calculated Volume = 360 Gal
If Measured Volume = 340 Gal
Calculated Vol x Pump Flow / Measured Volume
= Correct GPM
360 Gal x 140 Gal / 340 Gal = 148 GPM
8. Reset the pump ow to 148 GPM to obtain an
application rate of .3 Gal/Sq.Yd.
5. Use the measuring stick or weigh the machine to
determine the quantity sprayed.
6. Calculate the expected results.
For example:
900 Ft x 12 Ft Wide x .3 Gal/Sq Yd / 9 Sq Ft/Sq Yd
= 360 Gal.
or
600 Ft x 12 Ft Wide x .3 Gal/Sq Yd / 9 Sq Ft/Sq Yd
= 240 Gal.
7. If the measured volume does not equal the
calculated volume, adjust the ow rate to make them
equal.
