Rosco CSV - Augers; Spread Hopper Gate Selection

The conveyor system can be damaged
by setting the conveyor speed too high, which
causes the conveyors to start and stop continuously
and can shock the system.
Never leave the chip spreader
unattended while the conveyors are operating.
Never allow anyone near the
conveyors during operation as serious injury or even
death can occur.
Augers
An auger shaft inside the
spread hopper rotates to
keep aggregate owing to
the spread hopper evenly.
(Figure 4-35) The spread
roll at the bottom of the
spread hopper moves
aggregate out of the hopper
through cut-off gates to
spread evenly onto the
road surface. One or both
augers can be operated as
needed.

The auger control buttons are located directly above the
conveyor control buttons. Select auto or manual (and
auger speed in the manual mode) using the left and right
auger switches on the control panel. (Figure 4-36) The
center position is off.

When operating in the Auto mode, the augers
automatically enable and function based upon the FPM
speed set by the operator. While stationary, the augers
will move at a low speed and increase per the set FPM
speed when moving forward.
There are three speeds available using the Up
(increases speed) and Down (decreases speed) arrows
on the auger speed switch. The button arrows illuminate
a different color for each speed as shown in the table
below:

Spread Hopper Gate Selection
The CSV Variable Width Chip Spreader has two main
spread hopper gate extenstions, each with eight (8)
individual gates that can be opened and closed manually
or automatically. (Figure 4-37) One or both spread
hoppers can be extended or retracted simultaneously,
depending upon the spread width needed for the
job, with a width of up to 16 feet. Each individual gate
controls a one-foot spread-width section of the spread
hopper.
