Rosco Maximizer 3B Asphalt Distributor 6-51
Operation
3. Start spraying as you cross the start line. Maintain
the ground speed and engine RPM at the values
recorded on the data sheet.
4. Watch the pump GPM on the Run Screen readout
closely. You may have to adjust the speed slightly to
compensate for the change between Bar Circulate
and Spray. Use the Manual Pump Speed dial to
make the adjustment.
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.
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.
6. Operate the unit in the Bar Circulate Mode. Use the
Manual Pump Speed dial on the Plus One Controller
to set the pump ow to 140 GPM at the specic
engine RPM for operation.
7. Drive the unit over the application route in the
specic gear, axle ratio, engine RPM and travel
speed, and set the pump rate.
8. Record all operating parameters on your data sheet
(Table 6-4. Valve Status During Operational
Modes) for future reference.
NOTE: Small variations in ground speed will not
affect the application rate. As the truck speed
increases or decreases, there will be a
proportional increase or decrease in the ow
from the hydrostatic pump. This will also give a
proportional change in the asphalt pump ow.
Trial Run
A trial run can be made with the unit spraying to verify
the application rate. This may be required if the material
being sprayed has a viscosity that is different than that
normally sprayed.
1. Measure the amount of material in the tank. Read
the measuring stick in the top opening or weigh the
unit before and after the run to measure the volume
sprayed during the run. This latter method requires
that you know the density or the weight per gallon of
the asphalt.
2. Mark out a known distance on the spraying area.
Use even numbers such as 600 or 900 feet to make
the calculations easy. Allow a starting distance
before you begin spraying so the truck speed and
pump ow stabilize.
