Hydraulic Controls and Gauges
361044
Vibrator Pressure Gauge: Monitors the amount
of pressure required to operate the vibrator circuit.
Amount of pressure required will depend on the
number of vibrators being operated and their speed.
Normal operating pressure range is 500 to 1500 psi
(34 to 103.4 bar). Stall pressure for the vibrator system
is 2000 psi (138 bar). One pump supplies oil to the
conveyor, vibrator and lift hydraulic systems.
Track Pressure Gauge: Monitors the amount of
pressure required to operate the track drive system in
forward or reverse. Normal operating pressure range
is 500 to 1800 psi (48 to 124 bar). Relief pressure
setting for the tractive system is 2500 psi (172 bar).
Conveyor Pressure Gauge: Monitors the amount of
pressure required to operate the charging conveyor.
Amount of pressure required will depend on the
amount of concrete on the conveyor. Normal operating
pressure range is 500 to 1800 psi (34 to 124 bar).
Relief pressure setting for the conveyor system is
2000 psi (138 bar). One pump supplies oil to the
conveyor, vibrator and lift hydraulic systems.
Note: If the machine is equipped with an auger
conveyor, the relief pressure setting on the pump
is increased to 2200 psi (151 bar).
Trimmerhead Pressure Gauge: Monitors pressure
required to drive the trimmer wheel. Normal operating
pressure range is 500 to 2500 psi (34 to 172 bar).
Pressure will vary depending on depth of cut, width
of cut, grade density and forward travel speed. Relief
pressure setting for the trimmer system is 3600 psi
(248 bar).
Lift Pressure Gauge: Monitors the amount of
hydraulic pressure available for machine elevation and
steering control. Normal lift pressure is 2000 psi (138
bar). One pump supplies oil to the conveyor, vibrator
and lift hydraulic systems.
Note: If the lift pressure drops below 1500 PSI
(103 bar), the machine control may become slow.
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 ow 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 ns, 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.
Draw Bar Pressure Gauge: Monitors the amount of
pressure applied to the hydraulic cylinder holding the
front of the slipform mold down in contact with the
concrete. The regulated pressure range is 0 to 800 psi
(0 to 55 bar).
Drawbar Hold Down Pressure Control Valve: Used
to adjust the amount of pressure holding the front of
the slipform mold down on the concrete. Pressure

GT-3600 G+
2-2
adjusts from 30 to 800 psi (2.1 to 55 bar) by turning
the control dial clockwise to increase pressure and
counterclockwise to decrease pressure.
Form Hold Down Pressure Gauge: Monitors the
amount of pressure applied to the hydraulic cylinder
holding the rear of the slipform mold down in contact
with the concrete. The regulated pressure range is 0 to
800 psi (0 to 55 bar).
Hold Down Pressure Control Valve: Used to adjust
the amount of pressure holding the rear of the slipform
mold down on the concrete. Pressure adjusts from 30
to 800 psi (2.1 to 55 bar) by turning the control dial
clockwise to increase pressure and counterclockwise
to decrease pressure.
361041
Filter indicator lights: Indicate when the various
hydraulic lters need servicing. The main hydraulic

Panel" on page 2-11) must be in the remote position.

GT-3600 G+
2-6
Note: Contact GOMACO for more information if
the machine is not equipped with the remote.
Manual steer dial: Turns the tracks when the manual
steer select mode is in one of the four manual
positions. The control system is equipped with two
manual steer dials, one on the remote and one on the
console. The console/remote switch determines which
steer dial will operate the system (see the console/
remote switch description later for more information).
When the indicator on the manual steer dial is
centered, the tracks turn straight ahead. As the dial is
turned either direction from center, the tracks will turn
accordingly. The more the dial is turned, the more the
tracks will turn. The manual steer dial has no a󰀨ect
on the steering when the steer select switch is in the
stringline steer ( ) position. To use the manual steer
dial, the controller must be in run mode and all three
steering modules must be in automatic (A) (see "Run
Menu" on page 2-18 for more information).
Travel variable control dial: Controls the travel speed
of the machine in either forward or reverse. The control
system is equipped with two travel variable control
dials, one on the remote and one on the console. The
console/remote switch determines which travel dial
will operate the system (see "Switch Panel" on page
2-11 for the console/remote switch description).
Rotate the control dial counterclockwise to the “o󰀨”
position to stop the track drive system. Rotate the
control dial clockwise away from the “o󰀨” position to
start moving the track drive system. The more the
control dial is turned clockwise, the faster the machine
will travel.
The travel variable control dial also starts and stops
the vibrators when the vibrator auto/o󰀨 switch is in the
“auto” position and the forward/reverse switch is in the
forward (F) position. When the travel variable control
dial is rotated away from the “o󰀨” position, all vibrators
begin operating at approximately 5% travel speed. The
tracks will begin moving at approximately 10% travel
speed. When the dial is rotated to the “o󰀨” position, the
vibrators stop.
Note: The controller must be in run mode to allow
operation of the travel control systems.
Conveyor On/O󰀨 Switch: Controls the on or o󰀨
operation of the conveyor. The switch is located on the
side of the remote. The “on” position will operate the
conveyor at the speed and direction determined by
the console conveyor speed dial and FNR (forward/
neutral/reverse) switch. The “o󰀨” position will stop the
operation of the conveyor. The switch will function only
when the console/remote switch is in the “remote”
position.
310154
