Rosco Maximizer 3B Asphalt Distributor 6-29
Operation
9. Set the height of the spraybar to obtain triple fan
coverage using the chains to x the down position.
If the day is very windy, use slightly less than triple
coverage to avoid wind drift of the asphalt, (see
Asphalt Spraybar in Section 6).
10. Clear the area of bystanders.
DO NOT SMOKE around the machine.
Fuel, asphalt material and the fumes from both
can explode when exposed to ame or heat from
smoking or other sources.
Beware of hot material in lines. Always
wear protective clothing, gloves and a face shield.
Contact with hot asphalt can cause severe burns.
11. Align the truck with the area to be sprayed. Position
the truck so the rear wheels are even with the stop
point of the last shot. Do not let the rear wheels get
into the fresh oil from the last shot.
12. Proceed toward the area to be sprayed. As the
spraybar crosses the starting point, push the
Spraybar Master switch DOWN to the ON position.
The valves for each nozzle will be opened and the
spraying will begin.
13. When the spraying run is nished, push the
Spraybar Master switch UP to BAR CRCLT. The
nozzle valves will close and the spraying will stop.
14. Leave the Mode Selection control in SPRAY/
BAR CRCLT if you want to keep the spraybar
components hot, or refer to the Reverse Suction
Mode for instructions on how to draw excess
asphalt out of the spraybar and piping.
Spray / Bar Circulate Mode
(Spray)
This section explains the procedure to be followed
when spraying asphalt (Figure 6-19). Review these
instructions and follow them to insure the safety of the
operator and to maintain a safe working environment.
1. Turn the Plus One Controller Master switch ON to
activate the system, (Figure 5-2,1).
2. Set the Plus One Controller Auto/Manual selection
to AUTO and the Pump Control priority selection
to FRONT. The Controller will then control the
spraybar circulate rate.
3. Turn the Mode Selection switch to SPRAY/BAR
CRCLT position.
4. Push the Spraybar Master switch UP to the BAR
CRCLT position.
5. Be sure that the Plus One Controller has been
programmed to deliver the specied amount of
asphalt. Turn on individual spraybar switches on
the Controller panel for the spraybar sections to be
used, (see Plus One Controller in Section 6).
6. Run the Maximizer 3B in SPRAY/BAR CRCLT
mode for at least 5 minutes to heat the spraybar
components to operating temperature.
7. Check the temperature of the material in the
tank. Heat the material before starting if it is at the
low end of the operating range, (see Material
Considerations in Section 4).
8. Extend the spraybar sections into their operating
conguration.
