Rosco Maximizer 3B Asphalt Distributor 6-19
Operation
Distance Calibration
Distance calibration makes sure the distributor
accurately measures the distance travelled. Similar
to ow calibration it compares a known distance with
the actual distance travelled and compensates for any
difference. Select Distance Calibration from the setup
menu. Clear the totals and drive a known distance.
Complete Distance Calibration by entering the actual
distance travelled.
Bar Calibration
Select bar calibration from the main menu of the In-Cab
Controller. The screen will prompt to retract the bar to
be calibrated. Once the bar is retracted the screen will
give the opportunity to reset the calibration values.
Extend the bar until the screen indicates that the
calibration is complete. If the SPRAYBAR CALIBRATION
SCREEN indicates that the calibration is out of range,
the Bar Sensor must be repaired.

Rear Fender Controls
Rear controls are located in the right hand side rear
fender tool box and are used to control asphalt pump
speed, asphalt pump direction, spraybar hydraulic
functions and the optional washdown pump. Rear
control priority must be set to use asphalt pump (see
Rear Controller in Section 5).
Flow/Distance Calibration

Flow Calibration
Flow calibration compares a programmed volume of
material to be applied with the actual volume of material
used and then compensates for the difference. This
procedure is done to assure accurate application of
material.
From the setup menu the operator can select ow
calibration. Clear the gallons total and then enter auto
spray mode to spray an amount of asphalt. Dip the tank
with the measuring stick before and after spraying to
determine how much material was sprayed. Entering the
actual amount of asphalt used will calibrate the control
system.
