Rosco Maximizer 3B Asphalt Distributor 6-5
Operation
Hydrostatic Circuit
It may be necessary to run the engine at 1500 RPM to
provide sufficient oil flow to the hydrostatic circuit to
operate the asphalt pump.
Do not run the asphalt pump for more
than 15 minutes with no material in the system. Seal
damage could occur.
NOTE: If the machine is equipped with a PTO system,
perform all functional checks after the PTO has
been engaged and is running.
1. Start the truck engine and run at low idle.
2. Turn the Plus One Controller Master switch ON
( Figure 5-2,1 ) to activate the system. Set the Auto/
Manual switch to MANUAL, ( Figure 5-2 )
3. Be sure the Mode Selection is set to OFF ( Figure
6-1 ).

4. Set the Front/Rear control (
Figure 5-4,3
) to the
FRONT position. Turn the Manual Pump Speed dial
clockwise and verify that the asphalt pump rotates
in the clockwise direction as viewed from the right
side of the machine. Turn the Manual Pump Speed
dial to the center position (0 on the dial), to stop the
pump.
5. Rotate the Front Manual Pump Speed dial ( Figure
5-2,3 ) counterclockwise and verify that the asphalt
pump rotates in the counterclockwise direction as
viewed from the right side of the unit. Return the
Manual Pump Speed dial to the center position (0
on the dial), to stop the pump.
Functional Check
Before starting the day’s work, perform a functional
check on each system and major component to insure
that each is functioning properly. Use two people - one
person in the truck cab to run the engine and Maximizer
3B controls, and one person at the appropriate check
point.
Keep safety in mind and make sure
that personnel, vehicles, and property are clear
of the distributor during the functional check.
Hydraulic Circuit
The Maximizer 3B is equipped with electric solenoids
that control the hydraulic circuit. The solenoids are
located inside the rear platform.
1. Start the truck engine and run at low idle.
2. Turn the Plus One Controller Master switch ON to
activate the system, ( Figure 5-2,1 ).
NOTE: If equipped with PTO driven hydrostatic pump,
follow steps 3 and 4. If not, go to step 5.
3. Engage the PTO clutch.
Manual Transmission: Set parking brake. Depress
clutch pedal, place transmission in neutral,
engage PTO clutch and release clutch pedal.
The hydraulic and hydrostatic systems should
now be functioning.
Automatic Transmission: Set the parking brake. Apply
vehicle brakes, and place the transmission
in neutral. Engage the PTO. The hydrostatic
systems should now be functioning.
It may be necessary to let the truck
creep forward slightly to allow the clutch to engage.
Be sure that all personnel are clear of the vehicle.
4. Press the Spraybar Lift switch ( Figure 5-2,11 ) UP to
raise the spraybar to its highest position.
5. Press the Spraybar Lift switch ( Figure 5-2,11 )
DOWN and verify that the spraybar moves to its
down position.
6. Press the Left Bar Extend/Retract switch to the left
and verify that the spraybar extends fully to the left.
7. Press the Right Bar Extend/Retract switch to the
right and verify that the spraybar extends fully to the
