PAVER CONTROLS
Before starting engines read the engine starting
instructions and all warning decals located on the
operators console and at other key points on the
machine.
Both carriage travel and machine travel are controlled from the opera-
tor’s control console . Optional accessories are also controlled from the
control console .
A. Manual Carriage Directional Control
- Can be used to change the
direction of the carriage travel . When the Carriage Directional Control
is moved in either direction from the center position the carriage travel
speed begins to slow down . To reverse the direction of the carriage
travel move the control all the way in the direction of the desired travel .
Move the control lever with a smooth, steady motion to avoid jerky
carriage travel starts and stops . An alternative method to reverse travel
is to stop the carriage travel using the Power Selector Control . Move
the Power Selector Control to the “Stop” position . Reverse the carriage
travel by moving the Carriage Directional Control in thedesired travel
direction and then return the Power Selector Control to the “Pave” po-
sition .
CAUTION: When the Carriage Directional Control is
manually HELD in either direction the carriage will
continue to travel if (A) the Power Selector Control is
in the “Pave” position, (B) the Machine Travel Direc
-
tion Controls are engage and (C) the Machine Travel
Speed Control is not set at zero.
B. Power Selection Control
- The power selection valve has three
functions, Pave, Stop and Travel . To avoid jerky carriage travel,
slowly ease the control to each new position . In the “Pave” position the
carriage will move back and forth across the machine truss . The “Pave”
position supplies power to the carriage travel drive and provides power
for the automatic machine travel drive . The machine travel drive will be

actuated each time the carriage automatically reverses direction .
CAUTION: Before engaging carriage travel be sure
that all personnel are clear of the paving carriage.
The paving carriage will not automatically reverse
direction of travel when it reaches the end of the ma
-
chine unless the carriage travel reversing lugs are
installed on the carriage travel chain. For instruc
-
tions on setting the reversing lugs see Section III -
“Set-up” Instructions.
The “Stop” position is used when starting the Power Unit Engine and to
automatically stop all functions . The “Travel” position is used for man-
ually moving the machine in either the forward or the reverse direction .
C. Carriage Speed Control -
The Carriage Speed Control determines
the speed of both the paving carriage and any accessories installed on
the unit . This valve controls the amount of hydraulic oil going to any
one of the control valves on the operator’s console . The zero (0 ) setting
being no oil flow to the valves and the ten (10) setting being full flow to
the valves. Keep the Carriage Speed Control scale setting at 10 (max
-
imum) 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 con-
trols 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 man-
ual mode is used to move the machine without activating the paving
