Rosco Maximizer 3B Asphalt Distributor 6-49
Operation
Manual Operation
The Maximizer 3B comes equipped with the Plus One
Controller that will automatically set and maintain the
operator’s required application rate. Rosco strongly
recommends that the operator depend on the Controller
rather than setting the application rate manually. The
Controller’s calculations are more reliable and accurate.
In the event that manual operation is required, follow the
instructions provided in this section.
Asphalt application rates are dependent upon nozzle
size, pump speed, ground speed and spraybar
width. Carefully review and follow the procedures for
calculating the required settings, simulating a run and
doing a trial run to be sure the desired application rate is
obtained.
Calculations
To obtain the desired performance, use the Slide Rule
Application Guide (Figure 6-40), supplied with the
Maximizer, to determine the settings of the machine.
Determine the type of nozzles used on the spraybar. The
nozzle type will determine the range of pump ow that
will give an acceptable nozzle spray pattern.
Determine the application rate in Gal/Sq. Yd. or Liter/Sq.
Meter for the work to be done. This will be specied by
the job requirements and selected nozzle size.
Determine the ground speed, pump ow and the
spraybar width being used for each specic job.
The slide rule covers spraybar widths from 4 feet to 24
feet in 1 foot increments.
