Hydraulic Filter Pressure Gauge: Monitors the
amount of pressure required to force the hydraulic oil
through the main hydraulic filter. Normal operating
pressure is below 25 psi (1.72 bar). During cold
weather start-up, the filter pressure may exceed 25
psi (1.72 bar). The filter must be changed when the
gauge registers in the replace area with the hydraulic
fluid at operating temperature.
Hydraulic Oil Temperature Gauge: Monitors
the hydraulic oil temperature. Normal operating
temperature is 140° to 180° F (60° to 82° C)
depending on the ambient temperature. If the
hydraulic oil temperature rises above 195° F (90.5°
C), locate the cause of the overheating. Overheating
can be caused by excessive load on all systems on a
warm day, air flow through the oil cooler(s) restricted
and/or by a system that is constantly exceeding
relief pressure. The overheating can be corrected
by reducing the load on all systems on a warm day,
cleaning the oil cooler fins, and/or by reducing the load
on the various systems to maintain pressure below
relief setting.
Note: Excessive oil temperature may cause
serious damage to components.

Vibrator Variable Control Valves: Used to
individually control the vibration output of each
hydraulic powered concrete vibrator in the slipform
mold. Controls vibrator output from 0 to 10,500
vibrations per minute. Rotating each control dial
counterclockwise increases vibration and clockwise
decreases the vibration in the corresponding vibrator.
Turning the dial all the way clockwise stops the
vibrator attached to that circuit.

Contact with moving tracks can cause serious
injury. Be certain that no one is near the tracks
before moving them. Do not stand on moving
track. Do not operate the machine with the track
guards (fenders) removed. Keep hands, feet and
loose clothing away from moving parts to prevent
severe injury.
Manual Override Control Buttons: Used for
troubleshooting the steer and grade systems to
determine if the fault is electrical or hydraulic. The
valves are located on each elevation leg. Release
the latch and raise the hinged cover. Press the
