Rosco Maximizer 3B Asphalt Distributor 6-23
Operation
to an approved container before loading. Dispose
of material and water according to local, state and
federal regulations.
Fumes from asphalt materials can
be poisonous. When using the top opening, the
operator should stand up-wind and to one side to
avoid hot gases, fumes or being struck by a cover or
hot asphalt spray.
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.
Hot material will turn water into steam
and can cause an explosion.
Check that the material being loaded
is compatible with the previously used asphalt, (see
Guide For Loading Asphalt Products in Section 4).
Some asphalt material can be vaporized by high
temperature materials and can explode. If material is
not compatible, clean out the tank.
4. Move the Maximizer 3B to the storage tank or
transfer vehicle.
Never operate burner when the vehicle
is being loaded or in transit. The ue tubes can
become exposed, causing an explosion inside the
tank or material being sprayed could ignite.
Always wear protective clothing,
gloves and a face shield. Contact with hot asphalt
can cause severe burns.
5. Position loading hose at top of the tank and open
Top Opening cover.
6. Clean strainer in Top Opening cover before loading.
7. Position end of the hose in strainer and start pump
on storage tank or transfer vehicle to load the tank.
Be sure that hose stays in Top Opening. It may be
necessary to hold it or tie it to lid hinges or platform
to keep it in place.
8. Fill until tank is 80% to 90% full.
9. Reverse storage tank pump to draw excess material
out of loading hose.
10. Remove hose from Top Opening and close cover.
Some residue will remain in the line.
Always wear protective clothing, gloves and a face
shield. Contact with hot asphalt can cause severe
burns.
11. Remove the hose from the storage tank and stow as
appropriate.
11. Slowly open the small vent valve (Figure 6-16,5) to
the top left of the Load Line coupler, (Figure 6-15)
to relieve the vacuum in the line. When suction relief
is heard, remove the Load Line cap. If no relief is
heard, do not remove the cap. Check that pump is
turning in the forward direction and that the vent
valve is open.
Never remove the Load Line cap
unless the pump is turning in the forward direction
and the vent valve is open. Hot asphalt in the load
line is under pressure and could spray the operator.
Check the direction by opening the vent valve.
12. After removing the Load Line cap, close the vent
valve. Connect the loading hose. Be sure the over
center latches lock the coupler in place.
13. Using the Rear Controller (Figure 5-3), run the
asphalt pump in FORWARD at 50 - 150 GPM.
14. Fill until the tank is 80% to 90% full.
15. When the tank is î›™lled, slow the pump speed so that
it just provides suction to the line. (50 - 75 GPM)
16. Close the valve at the storage or transfer tank to
stop the ow.
17. Open the small vent on the top left of the Load Line
to allow the pump to draw material out of the load
line.
Some residue will remain in the line.
Always wear protective clothing, gloves and a face
shield. Contact with hot asphalt can cause severe
burns.
18. Disconnect the loading hose, replace the cap,
secure latches, close the small vent valve and stow
the loading hose.
19. Set the Plus One Controller Pump Control priority
selection to REAR.
20. Set the Plus One Controller Mode Selection control
to TANK CRCLT.
