Sound and Vibration Measurements
According to Appendix 1, paragraph 1.7.4.f of the EG-Machine
Regulation, the requested noise levels are:
The sound pressure level at operator's location (LpA) = 83 dB(A).
The guaranteed sound power level (LWA) = 109 dB(A).
These noise values were obtained at the operator's location according
to ISO 3744 for the sound power level (LWA) and ISO 6081 for the
sound pressure level (LpA).
Noise levels were measured while running the machine at full speed,
on crushed gravel, with vibration on.
Because this machine is operated using remote control the operator is
not exposed to vibration.

Maintenance
3.18 Cleaning CombiControl Transmitter
The transmitter and switches are completely sealed to keep dust and
moisture out; however, contact with water should be kept to a
minimum. Even a small amount of moisture can cause connections
and contacts to corrode. Avoid immersing transmitter in water and do
not clean using a pressure wash.
To clean the transmitter, wash off using a damp cloth and allow to dry.
To remove dirt and dust trapped around switches, use compressed air.
Keeping the hydraulic oil clean is a vital factor affecting the service life
of hydraulic components. Oil in hydraulic systems is used not only to
transfer power, but also to lubricate the hydraulic components used in
the system. Keeping the hydraulic system clean will help avoid costly
downtime and repairs.
Major sources of hydraulic system contamination include:
•
Particles of dirt introduced when the hydraulic system is opened
for maintenance or repair
•
Contaminants generated by the mechanical components of the
system during operation
•
Improper storage and handling of hydraulic oil
•
Use of the wrong type of hydraulic oil
•
Leakage in lines and fittings
To minimize hydraulic oil contamination:
CLEAN hydraulic connections before opening the lines. When adding
oil, clean the hydraulic tank filler cap and surrounding area before
removing it.
AVOID opening the pumps, motors, or hose connections unless
absolutely necessary.
PLUG or cap all open hydraulic connections while servicing the
system.
CLEAN and cover the containers, funnels, and spouts used to store
and transfer the hydraulic oil.
CHANGE the hydraulic filters and oils at the recommended service
intervals.

RT 560 / RT 820
3.19 Hydraulic Oil Requirements
Wacker recommends the use of a good petroleum-based, anti-wear
hydraulic oil in the hydraulic system of this equipment. Good anti-wear
hydraulic oils contain special additives to reduce oxidation, prevent
foaming, and provide for good water separation.
When selecting hydraulic oil for your machine, be sure to specify antiwear properties. Most hydraulic oil suppliers will provide assistance in
finding the correct hydraulic oil for your machine.
Avoid mixing different brands and grades of hydraulic oils.
Most hydraulic oils are available in different viscosities.
The SAE number for an oil is used strictly to identify viscosity—it does
not indicate the type of oil (engine, hydraulic, gear, etc.).
When selecting a hydraulic oil be sure it matches the specified SAE
viscosity rating and is intended to be used as a hydraulic oil. See
Technical Data—Lubrication.
3.20 Hydraulic Fluid Level
See Graphic: wc_gr000483
A hydraulic oil level sight gauge (e) is located on the hydraulic tank
inside the rear section of the machine.
Check that the oil level is within 25 mm (one inch) of the top of the sight
gauge. Add oil as required through the filter housing on top of
hydraulic tank.
If hydraulic oil continually needs to be added, inspect hoses and
connections for possible leaks. Repair hydraulic leaks immediately to
prevent damage to hydraulic components.

3.23.2
Clean or change air cleaner elements.
3.23.3
Clean the engine cylinder cooling fins.
3.23.4
Drain any water that may have collected at the bottom of the fuel tank.
Replace the fuel filter. Refill the tank with fresh No. 2 diesel fuel.
Note: Diesel fuel is subject to bacterial growth which can contaminate
fuel lines. Allowing the tank to sit dry for a long period of time helps
promote such growth. The addition of a biocide to the fuel is
recommended to inhibit bacterial growth and protect the engine fuel
system.
3.23.5
Store the unit indoors in a clean dry area. If the unit must be stored
outside, cover it.
3.24 Jobsite Storage
See Graphic: wc_gr000486
Never allow the roller to sit overnight in a ditch, trench or other lowlying area which might fill with water during a heavy rain. Park the roller
on a flat level surface, out of the way of traffic patterns and congestion.
If the roller must be parked on an incline, chock the drums to prevent
any chance of movement.
If leaving the roller on the job site, remember to remove the key and
lock the control panel cover and engine hood to prevent tampering.
Both the front and rear hoods and access cover are equipped with a
locking ring (a) for use with a padlock for this purpose.
If desired, the CombiControl can be removed from the roller and stored
separately.

Hydraulic System
See Graphic: wc_gr002481 and wc_gr002482
Description:
Pressure in the hydraulic system is generated by two gear pumps
mounted in tandem to the back of the engine. The pumps are driven
by a common shaft which is connected to the engine crankshaft
through a three-piece coupling. Capacity of the front pump (d) is
approximately 8 gpm (32 l/m) and is used to operate vibration or high
speed travel. Rear pump (e) capacity is approximately 4 gpm (16 l/m)
and is used for low speed travel.
A control valve block directs oil flow from the pumps to the motors and
steering cylinder. The control valve block is mounted beneath the
control panel at the rear of the machine. It consists of the manifold (j),
vibration (i), travel (k) and steering (l) valves. These valves are
solenoid operated. During operation, the solenoids respond to the
electrical signals being transmitted by the operator from the control
box. Two reliefs, located on the main manifold, limit exciter and drive
pressures to 3000 PSI (21 mPa). The steering circuit relief is mounted
on the steering valve and is set at 1000 PSI (7 mPa). See section
Control Valve Block for control valve components.
Oil from the hydraulic tank (c) flows through a suction strainer (a)
before it is drawn into the pump suction port. The suction strainer is
mounted in the tank and is magnetic for removing metal particles.
Hoses connect the output ports of the pumps to the main manifold (j)
on the control block. The main manifold directs oil flow into the
vibration (i) and travel (k) valves. These valves in turn supply hydraulic
pressure to operate the exciter and drive motors.
When operating in low-speed travel, the larger front pump is used to
operate the exciter motors (n, r), the smaller rear pump is used to
operate the drive motors (o, q). When operating in high-speed travel,
the main manifold redirects front pump oil flow away from the exciter
motors to the drive motors. Flow from the rear pump is directed back
to the tank. In high-speed travel the exciter motors do not operate. See
later sections in this unit for a detailed description of the exciter and
drive circuits.
Return oil from the drive circuit flows to the steering valve (l) which
directs it to the steering cylinder (g).
The hydraulic system is protected by a return line filter (b). The return
line filter removes particles down to 10 microns and includes a by-pass
for cold weather start-up.

RT 560 / RT 820
Hydraulic System
Oil Cooler & Brake:
Return flow from the steering valve is directed through a check valve
(m) to the oil cooler (f) before returning to the hydraulic tank.
A hydraulic brake (p) is available on machines with item numbers 9001
& 9003. The brake is connected to the hydraulic system through the
main manifold (j) and brake valve (h). The brake is spring loaded and
normally set when the machine is off. When the hydraulic system is
pressurized, the brake is automatically released. The brake can be set
manually by setting the toggle switch on the transmitter module. This
activates the solenoid on the brake valve (h) and releases the
hydraulic pressure to the brake. This will also shut off the engine.

The solenoids located on the vibration and travel valves are equipped
with manual over-rides. Use of these over-rides for testing machine
functions is not recommended. Pushing any of the over-ride buttons
while the engine is running will cause sudden machine movement and
could result in a serious or fatal injury. If testing must be done using
these over-rides, stand at side of machine and make sure feet are
away from drums before pushing button.

4.10 High-Speed Travel Circuit Description
See Graphic: wc_gr002485
Note: The diagram shows the direction of oil flow when operating in
forward at high speed travel, vibration switch in OFF position.
High speed travel is obtained by using the full flow from the larger front
pump (g) to operate the drive motors. This is accomplished by
switching flow from the front pump away from the exciter circuit and
into the drive circuit. The pilot-operated directional control valve (h)
located in the main manifold valve (k) is used to do the switching.
Oil flows from the rear pump (f) to the travel speed valve (c). When the
operator switches to high speed travel, the travel speed solenoid is
energized, which shifts the valve to the position shown. In this position,
oil flows through the valve and returns to the hydraulic tank. This
causes pilot oil pressure at the directional control valve (h) to drop, and
allows spring force in the valve to shift the spool to the position shown.
In this position, oil flow from the front pump is directed to the brake,
drive, and steering circuits. There is no flow to the exciter motors.
Relief valve (j) limits hydraulic pressure in the drive circuit to 3000 psi
(21 mPa). Check valve (i) prevents front pump oil flow from
pressurizing the pilot circuit and shifting the directional control valve.
Machine forward and reverse directions are controlled by the solenoidoperated travel valve (a) which switches the direction of oil flow
through the valve and drive motors.
When the operator switches to forward, the bottom solenoid on the
travel valve energizes, which shifts the valve spool to the position
shown. In this position, oil flows through the valve, rear drive motor (e),
front drive motor (d), and back through the valve to the steering circuit.
With the directional controls in neutral, both solenoids are off and
springs in the travel valve (a) return the spool to a neutral position.
Operation in reverse will cause oil through the travel valve (a) to flow
opposite the direction shown, reversing the direction of the drive
motors.
Note: Top or bottom as described above refers to the location of the
solenoids as installed on the machine.
A double check valve (b) provides a hydraulic lock to prevent the drive

4.15 Low-Speed Travel Circuit Description
See Graphic: wc_gr002486
Note: The diagram shows the direction of oil flow when operating at
low speed travel and going forward, vibration switch in OFF position.
Low speed travel is obtained by using oil flow from the smaller rear
pump (f) to operate the drive motors. This is accomplished by the
solenoid-operated travel speed valve (c), which directs flow from the
rear pump to the drive circuit.
Oil flows from the rear pump to the travel speed valve. When the
operator switches to low speed travel, the travel speed valve solenoid
(c) is turned off. This allows spring force in the valve to shift the spool
to the position shown. In this position, flow from the rear pump is
directed through check valve (i) and on to the drive and steering
circuits. High pressure oil is also directed to the pilot port of the
directional control valve (h). Spring resistance in the directional control
valve (h) is overcome by the increased oil pressure which shifts the
spool to the position shown. In this position, oil flow from the larger
front pump (g) is directed to the exciter circuit. A flow regulating valve
in the steering circuit always provides enough pressure to shift the
directional control valve even if the travel and steering function are in
neutral.
Relief valves (j, k) limit hydraulic pressure in the drive and exciter
circuits to 3000 psi (21 mPa).
Machine forward and reverse movements are controlled by the
solenoid-operated travel direction valve (a) which switches the
direction of oil flow through the valve and drive motors.
When the operator switches into forward, the bottom solenoid on the
travel valve energizes, which shifts the valve spool to the position
shown. In this position, oil flows through the valve, rear drive motor (e),
front drive motor (d) and back through the valve to the steering circuit.
When the operator switches into reverse, oil flow through the valve is
opposite the direction shown, reversing the direction of the drive
motors. When the machine is in neutral, both solenoids are off and
springs in the valve return the spool to neutral.
Note: Top or bottom as described above refers to the location of the
solenoids as installed on the machine.
A double check valve (b) provides a hydraulic lock to prevent the drive
motors from rotating while the machine is in neutral or turned off. When
pressurized, the pilot port in each check valve opens the valve and
allows oil flow in both directions.

4.16 Exciter Circuit Description
See Graphic: wc_gr002487
Note: The diagram shows the direction of oil flow when operating at
low speed travel with the EXCITER switch set to LO.
Operating in low speed travel opens flow from the front pump to the
exciter circuit. When operating in high speed travel the exciter circuit is
closed and all flow is directed to the drive motors .
When the operator switches to low speed travel, the travel speed valve
(d) is turned off. This allows spring force in the valve to shift the spool
to the position shown. In this position, flow from the rear pump is
directed through check valve (h) and on to the drive and steering
circuits. High pressure oil is also directed to the pilot port of the
directional control valve (c). Spring resistance in the directional control
valve is overcome by the increased oil pressure which shifts the spool
to the position shown. In this position, oil flow from the larger front
pump (g) is directed to the exciter circuit. A flow regulating valve in the
steering circuit always provides enough pressure to shift the directional
control valve even if the travel and steering functions are in neutral.
Low or high amplitude vibration is controlled by the solenoid-operated
exciter valve (l). This valve switches the direction of oil flow through
exciter motors.
With the VIBRATION pushbutton switch set in the low position, the top
solenoid is energized and the valve spool will be at the position shown.
In this position, oil flows through the valve, rear exciter motor (i), to the
front exciter motor (j) and back through the valve to the hydraulic tank.
When the VIBRATION pushbutton switch is in the high position, the LO
solenoid is turned off and the valve returns to neutral. A timer in the
electrical circuit keeps the valve in neutral for approximately 7 seconds
before turning on the HI solenoid. This allows the exciter weights to
stop rotating before reversing direction. With the exciter switch set at
HI, oil flow through the motors is opposite of the direction shown,
causing the exciter motors to reverse direction.
Note: Top or bottom as described above refers to the location of the
solenoids as installed on the machine.
Relief valve (e) limits hydraulic pressure in the exciter circuit to 3000
psi (21 mPa).

4.19 Steering Circuit Description
See graphic: wc_gr002488
Note: The diagram shows the direction of oil flow when steering left.
The steering circuit consists of a flow regulating valve (c), pressure
relief valve (f), solenoid-operated control valve (g), and steering
cylinder (h).
Return oil from the drive circuit flows into the steering circuit and
through the flow regulating valve (c) before entering the solenoidoperated steering control valve (g). The flow regulating valve
maintains a constant 1 gpm flow rate in the steering circuit. This is
necessary to provide the same degree of steering control whether
operating in low or high speed travel. It also creates sufficient back
pressure in the system to shift the directional control valve in the main
manifold. This keeps the exciter circuit open when the steering and
travel valves are in neutral.
When the operator steers left, the top solenoid on the steering valve
(g) is energized and the valve spool shifts to the position shown. In this
position, oil flows out port “E” of the valve, to the rod end of the steering
cylinder (h). At the same time, oil from the head end of the cylinder
returns through port “F” and back to the hydraulic tank. This causes the
cylinder rod to retract, turning the machine left. When the operator
steers right, oil flows in the opposite direction causing the cylinder rod
to extend and turn the machine to the right. With steering in neutral,
both solenoids are turned off. Springs in the valve return the spool to
center which allows oil to pass through the valve, out port “T”, and back
to tank.
Note: Top or bottom as described above refers to the location of the
solenoids as installed on the machine.
Relief valve (e) limits hydraulic pressure in the steering circuit to 1000
psi (7 mPa).

4.21 Hydraulic System Cleanliness
Keeping the hydraulic fluid clean is a vital factor affecting the service
life of hydraulic components. Oil in hydraulic systems is used not only
to transfer power, but also to lubricate the hydraulic components used
in the system. Keeping the hydraulic system clean will help avoid
costly downtime and repairs.
Major sources of hydraulic system contamination include:
• Particles of dirt introduced when the hydraulic system is opened for
maintenance or repair.
• Contaminants generated by the mechanical components of the
system during operation.
• Improper storage and handling of hydraulic fluid.
• Use of the wrong type of hydraulic fluid.
• Leakage in lines and fittings.
To minimize hydraulic fluid contamination:
• Clean hydraulic connections before opening lines. When adding oil,
clean hydraulic tank filler cap and surrounding area before removing.
• Avoid opening pumps, motors or hose connections unless absolutely necessary.
• Plug or cap all open hydraulic connections while servicing system.
• Change hydraulic filters and fluids at the recommended service
intervals.
4.22 Hydraulic Oil Requirements
WACKER recommends the use of a good petroleum-based, anti-wear
hydraulic oil in the hydraulic system of this equipment. Good anti-wear
hydraulic oils contain special additives to reduce oxidation, prevent
foaming and provide for good water separation.
Premium grade, anti-wear hydraulic fluid.
Viscosity: 10W30.
See Technical Data for quantity.
Most hydraulic oils are available in different viscosities. The SAE
number for an oil is used strictly to identify viscosity—it does not
indicate the type of oil (engine, hydraulic, gear, etc.).

5.30 Shockmounts
See Graphic: wc_gr0002527
Each drum support is shockmounted to the machine frame at six
places, two at the outer mount (a) and four at the inner mounts (b).
Inspect shockmounts at regular intervals for damage and wear.
Replace shockmounts that are torn or split. The shockmounts isolate
and protect the frame and upper components from excessive vibration.
Running the machine with damaged shockmounts can cause wiring
connections to weaken and may eventually damage other
components. When replacing shockmounts it is recommended that
both the left and right sides be done at the same time.

6.1
Tools
Because all possible problems encountered while repairing the
equipment cannot be anticipated, it is up to the mechanic to use
common sense and good judgement in tool selection.
The use of any special tools is recommended only for those operations
where the use of conventional tools proves inadequate.
Before substituting another tool or procedure, you should be satisfied
that neither personal injury nor damage to the component will result.
6.2
Ordering Parts
The repair procedures contained in this manual do not include part
numbers. For parts replacement information, refer to the Parts Book
originally supplied with the unit.
If the original Parts Book has been lost, a replacement may be ordered
from Wacker Corporation. When ordering a replacement Parts Book,
please list the model number, item number, revision level, and serial
number of the machine. Parts Books are also available on the Wacker
Corporation Web site. See www.wackergroup.com. Enter the site as a
visitor.
6.3
Reference Numbers ( )
Repair procedures contain reference numbers enclosed in
parentheses ( ). These numbers refer to the item numbers shown on
the assembly drawings and other detailed drawings. They are included
to aid the mechanic in identifying parts and assembling components.
6.4
Weight Block
See Graphic: wc_gr000843

CombiControl/Electrical System
7.1
CombiControl Features
See Graphic: wc_gr002567
This machine is designed specifically for remote control operation.
This feature protects the operator by allowing him or her to stand at a
distance from the machine, and the work area, during operation. When
used in excavations, it allows the operator to stand safely above the
trench, rather than in it.
The CombiControl transmitter is designed for both cable-controlled
and infra-red (IR) remote-controlled operations.
The Infra-red System includes the transmitter and receiving eye. This
system provides wireless line-of-sight operation up to 65 feet (20 m). It
uses a hand-held transmitter to transmit signals to a receiving eye on
the machine to control machine operation.
7.2
CombiControl Operation
See Graphic: wc_gr002568
The Infra-Red Control System will only operate if the control cable is
connected to the receiving eye receptacle on the roller (b).
During operation, keep the transmitter pointed at the receiving eye on
the machine to continue operation. The amber light on top of the
machine will blink slowly to show that the machine is receiving signals
from the transmitter. When the joystick is pressed fully forward, the
roller will go into high-speed travel, and the amber light will blink
rapidly.
The CombiControl transmitter batteries can be recharged at the end of
operations by connecting the transmitter receptacle (a) to the battery
charging cable (c).
The Cable Control System will only operate if the control cable is
disconnected from the receiving eye and connected to the transmitter
receptacle (a, d). In this mode, the CombiControl transmitter batteries
charge while the machine is in operation.
Always use the neck strap for the CombiControl transmitter provided
by WACKER. This neck strap is designed to break away so that the
operator will not be injured should the machine slide, tip, or fall.

Decoder Module
See Graphic: wc_gr002569
The decoder module (d) is positioned behind the rear panel at the back
of the machine. It receives, decodes and outputs the signal from either
the control cable or IR transmitter. It is also the power supply for all
electronic functions. It includes a channel selection microswitch.
A channel selection microswitch is also included in the transmitter
module. For operation of the remote control systems BOTH switches
must be set to the SAME channel.
The LED's (green and red) are there for diagnostic aiding. They are:
7.4
•
The green LED (f) will light when the decoder is receiving a control signal (joystick movement).
•
The red LED (g) will be constantly on for machines 9000 & 9002.
Setting Control Channels
See Graphic: wc_gr002569
The remote control system can be tuned to 3 different channels. This
allows three machines to operate in the same area without
interference.
A channel selection microswitch (e) is included in the CombiControl
transmitter module and in the decoder module (d), which is located
under the rear panel at the back of the machine.
For operation of the remote control systems BOTH switches must be
set to the SAME channel.
The channel comes preset from the factory to Channel 1.
To change the control channels:
Remove the four screws holding the CombiControl Transmitter box
together and carefully pull it apart. Remove the rear panel covering the
decoder module. Press both of the microswitches to change the
channel to any of the three channel positions.
Make a note of the channel in use, and label the CombiControl
Transmitter box and machine to identify the correct channel.
