Conveyors
Two hydraulically-controlled conveyor belts move
aggregate from the receiving hopper to the spread
hoppers. (Figure 4-33) Rubber chute liners on each
side of the conveyors prevent aggregate spillage and
can be adjusted to maintain even contact with the
conveyor belts if needed. (Page 5-9)
Figure 4-33. Conveyor Operation
One or both conveyors can be operated depending
upon the spread width needed for the job. The
conveyors can be operated in either Manual or Auto
mode and run almost continuously while chip spreading
to keep aggregate ow to the spread hoppers. Select
auto or manual (and conveyor speed in the manual
mode) using the left and right conveyor switches on the
control panel. (Figure 4-34) The center position is off.

Figure 4-34. Conveyor Controls
When operating in the Auto mode, the conveyors
automatically enable and function based upon the FPM
speed set by the operator into the DP710 digital display
unit. (Page 4-8) While stationary, the conveyors will
move at a medium-high speed and increase per the set
FPM speed when moving forward.
If operating conveyors in the Manual mode, the conveyor
speed may be adjusted to match spreading needs. The
proper conveyor speed should be set slightly faster than
spread requirements, stopping infrequently to ensure
aggregate does not overow in the spread hoppers.
(See Table 4-4 below.)
There are ve speeds available using the Up (increases
speed) and Down (decreases speed) arrows on the
conveyor speed switch. The button arrows illuminate
a different color for each speed as shown in the table
below:
