any truck speed. While in CRC, the system monitors the
vehicle speed and determines the proper pump parameters
to maintain the selected gallons per square yard (GSY) of
asphalt distribution. Automatic control occurs only when the
selector on the cab Console is in the ‘CRC’ position.
b. Manual control: In manual control, the pump speed is
determined by setting the manual pump speed on the
second page of the display, or by using the GSY switch on the
Console. Manual control is possible only when the selector
is in the ‘MANUAL’ position. The pump control functions are
described further in the ‘Cab Console Controls’ section of
this manual.
CAUTION:
INSUFFICIENT HYDRAULIC FLUID FLOW TO THE
HYDROSTATIC PUMP WILL CAUSE CATASTROPHIC
DAMAGE TO THE PUMP. INSUFFICENT HYDRAULIC
FLUID FLOW TYPICALLY INDICATES A CLOGGED FILTER,
BLOCKED HYDRAULIC LINE, OR LOW FLUID LEVEL.
The hydrostatic pump receives power directly from the PTO. It is a
quiet, smooth running unit under the conditions normally encountered
in asphalt circulation/heating operations. Excessive or unusual noise
from the pump may indicate a clogged filter, low fluid level or blocked
hydraulic line. The pump should never be operated under these
conditions.
