C. Carriage Speed Control
The carriage speed control establishes the speed of both the
paving carriage and any accessories installed on the unit. This valve
regulates the amount of hydraulic oil going to any one of the control
valves on the operator’s console. The zero (0 ) location being no oil flow
to the valves and the ten (10) location being full flow to the valves. Keep
the carriage speed control scale location at 10 (maximum) except when
slowing the paving carriage or when operating an accessory. When the
carriage speed is set at 10 the accessory speed will be set at 0. To
operate the carriage and an accessory concurrently set the control at
the midpoint of both scales (5). The paving carriage speed is variable
from 0 to 120 Ft/Min.
D. Machine Travel Direction Control
The machine travel direction valves control the forward or reverse
travel of the machine. The two control levers control the drive bogie on
the drive end of the machine and the drive bogie on the idler end of the
machine. With separate controls for each end, the machine is capable
of steering around a radius.
E. Machine Travel Speed Control
The machine travel speed control can be used in either a manual
mode or an automatic mode. The manual mode is utilized to move the
machine without starting the paving carriage.
Manual Mode:
1. The carriage speed control setting should be at the 10 location
on the scale.
2. BOTH machine direction controls need to be in either the forward
or reverse location.
3. The power selector control should be in the “Travel” location.
4. When the machine travel speed control is eased off of the “0”
location the machine will start to move.
Automatic Mode:
1. The carriage speed control should be off the “0” location. The
higher the setting the faster the paving carriage will travel through
the machine truss.
2. BOTH machine direction controls need to be in either the forward
or reverse location.
3. The machine travel speed control should be set off “0”. The higher
the setting the longer the advance will be when the carriage stops
and reverses direction.
4. Ease the power selector control to the “Pave” location. The paving
carriage will travel across the truss and slow down and shift direc-
tions. At the same time the machine truss will advance forward.
The length of advance depends on the machine travel speed con-
trol setting. The automatic machine advancement is variable from
0 to 15 inches with each carriage pass.
F. Carriage On/Off Valve
The hydraulic power needed to drive the rollers as well as the
augers, is controlled by the carriage On/Off valve. The valve is located
on the carriage control console. (See Figure 3).
