1.2 Machine Description and Intended Use

This machine is a dual drum, ride-on roller. The Wacker Neuson Ride­On Roller consists of an articulated frame onto which is mounted a
gasoline or diesel engine, a fuel tank, a hydraulic tank, a water tank, a
hydrostatic drive system, two steel drums containing internal eccentric
weights, and an operator’s platform with a ROPS (Roll Over Protective
Structure). The engine powers the hydraulic systems that provide
machine movement and drum vibration. The vibrating drums smooth
and compact the work surface as the machine moves. Machine speed,
direction, and vibration are controlled by the operator from the
operator’s seat on the platform.

The machine is designed as a lightweight roller to be used in the
compaction of sublayers and finish layers of asphalt on roads,
driveways, parking lots, and other types of asphalt-covered surfaces.

This machine has been designed and built strictly for the intended use
described above. Using the machine for any other purpose could
permanently damage the machine or seriously injure the operator or
other persons in the area. Machine damage caused by misuse is not
covered under warranty.

The following are some examples of misuse:

• Using the machine as a ladder, support, or work surface

• Using the machine to carry or transport passengers or equipment

• Using the machine to tow other machines

• Using the machine to spray liquids other than water (i.e., diesel
fuel on asphalt)

• Operating the machine outside of factory specifications.

• Operating the machine in a manner inconsistent with all warnings
found on the machine and in the Operator’s Manual.

This machine has been designed and built in accordance with the
latest global safety standards. It has been carefully engineered to
eliminate hazards as far as practicable and to increase operator
safety through protective guards and labeling. However, some risks
may remain even after protective measures have been taken. They
are called residual risks. On this machine, they may include exposure
to:

• Heat, noise, exhaust, and carbon monoxide from the engine

• Burns from hot hydraulic fluid

• Fire hazards from improper refueling techniques

• Fuel and its fumes

10 wc_si000399gb.fm

RD 16 Safety Information

• Personal injury from improper lifting techniques

• Crushing hazards from improper operation (feet, legs, or arms
extending outside of the operator work station) and for other per­sons in the work zone

• Line of sight blockage by the ROPS

To protect yourself and others, make sure you thoroughly read and
understand the safety information presented in this manual before
operating the machine.

3.13 Machine Stability

WA R NIN G

Crushing hazards. Certain job site conditions or operating practices may adversely
affect machine stability.

f

Follow the instructions below to reduce the risk of tipping or falling incidents.

Surface conditions

Pay attention to changing surface conditions while operating the
machine. Adjust speed and travel direction as necessary to maintain
safe operation.

• Machine stability and traction may be severely reduced when
operating on uneven or rough terrain, rocky soils, or wet or
loosely packed surface material.

• The machine may suddenly tip, sink, or fall when moved onto sur­faces that have been newly filled with earth.

Steering angle

An articulated roller is more likely to tip when moving off an elevated
surface if the machine is turned away from the edge.

• As shown in the illustration on the right, always turn the machine
toward the edge when moving off an elevated surface.

Travel speed

A fast moving machine is more likely to tip or fall over while making
turns or changing direction.

wc_gr00704

• Reduce travel speed before turning the machine.

Drum overhang

The machine can tip suddenly if more than half of the drum width
extends beyond the edge of the elevated surface.

42 wc_tx001075gb.fm

RD 16 Operation

• Reduce travel speed and watch the drum position carefully when
operating along the edge of an elevated surface.

• Keep as much of the drum on the elevated surface as possible.

Vibrating on a compacted surface

Activating the vibratory system on a fully compacted surface may
cause the drums to rebound and momentarily lose contact with the
ground. If this occurs while the machine is on an incline, the machine
may slide.

• If the drums rebound on the compacted surface, reduce vibration
speed or stop vibration entirely.

• parking brake button is pushed

50 wc_tx001075gb.fm

RD 16 Operation

3.21 Parking Brake Button

See Graphic: wc_gr002954

To hold the machine in a stopped position (parked), there is a
mechanical parking brake on each drum drive motor. The mechanical
parking brakes are spring-activated and hydraulically released (SAHR)
type brakes. The brakes are applied when the engine is switched off or
the operator leaves the seat.

When pushed in, the parking brake button (42) stops all travel (either
forward or reverse) and applies the brake. The brakes can be released
by pulling the parking brake button out.

The forward/reverse control (15) must be in the NEUTRAL position to
allow the release of the brakes. If the forward/reverse control is not in
the NEUTRAL position when the parking brake is released, the brakes
will not be released.

NOTICE: Under normal operating conditions, do not use the parking
brakes when the machine is moving. The parking brakes should only
be used in cases of emergency when the machine is moving, e.g.,
following failure of the main hydraulic braking system (moving the
forward/reverse control to the NEUTRAL position) or in a runaway
condition traveling down a slope. Using the parking brake while the
machine is moving may cause damage to the drive motors.

wc_tx001075gb.fm 51

Operation RD 16

3.22 Direction and Speed

See Graphic: wc_gr002954

The forward/reverse control (15) controls both the direction and speed
of the roller. Use the control lever, rather than the throttle, to control the
speed of the machine while compacting.

Speed is controlled by the amount the lever is moved in the direction
of travel—forward or reverse.

During operation, to run the machine at full throttle, press and release
the upper half of the throttle switch (HIGH) (54). This ensures
maximum travel speeds and will produce the best compaction results.
Operating the machine at slower engine speeds will reduce
compaction, slow down machine functions, and damage hydraulic
components.

RD 16 Operation

3.23 Transmission

See Graphic: wc_gr002954

Both roller drums are fitted with hydraulic motors which are driven by
an infinitely variable displacement pump and hydrostatic transmission.
Forward and reverse travel are selected using a forward/reverse
control (15) located next to the driver’s seat. In order to comply with
safety standards, the machine has a device which only enables
starting of the engine when the forward/reverse control is in the
NEUTRAL position.

Forward/reverse control
Shift the forward/reverse control (15) into FORWARD (F) or REVERSE

(R) according to the direction of travel desired. The further forward or

reverse the control is positioned, the faster the roller will travel.
Road speed is the same in both FORWARD and REVERSE. If you

wish to change direction of travel from FORWARD to REVERSE or
vice versa, move the control to the NEUTRAL position (N), allow the
vehicle to come to a complete stop, then move the control in the
direction desired.

During operation run the machine at high throttle. Quickly press and
release the upper half of the throttle switch (54) to bring the engine to
high throttle.

When negotiating gentle slopes, keep the engine at high throttle and
the forward/reverse control at the minimum speed position.

NOTICE: This vehicle has a hydrostatic transmission which means
that the forward/reverse control can also be used as an engine brake.
Shifting the control to the NEUTRAL position stops the machine travel.

NOTICE: Never drive the machine at low idle speed. Driving the
machine at low idle speed can damage the drive pump.

wc_tx001075gb.fm 53

4.13 Hydraulic System Cleanliness

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.

wc_tx001076gb.fm 77

Maintenance RD 16

4.14 Hydraulic Oil Requirements

Wacker Neuson 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
section Technical Data—Lubrication.

RD 16 Maintenance

4.15 Hydraulic Oil Level

See Graphic: wc_gr005895

A hydraulic oil level sightglass (29) is located on the side of the
hydraulic fluid reservoir.

While the machine is turned off, check that the hydraulic oil level is
visible at the middle level or higher in the sightglass. If it is not, add oil
through the filler port (20) inside the engine compartment. Use only
clean hydraulic oil.

Thoroughly clean the top of the filler cap before removing it from the
tank. Care should be taken to prevent small dirt particles from entering
the system.

If hydraulic oil continually needs to be added, inspect hoses and
connections for possible leaks.

4.17 Changing the Hydraulic Oil & Filter

Set all controls in neutral, stop the engine, and allow the engine and fluids
to cool before performing this procedure.

All oils eventually shear or thin out with use, reducing their lubricating
ability. In addition, heat, oxidation, and contamination may cause the
formation of sludge, gum, or varnish in the system. For these reasons,
it is important to change the hydraulic oil at specified intervals. See

Maintenance Schedule.

4.17.1 Remove the filler cap/filter cartridge from top of the hydraulic tank.

4.17.2 Remove the drain plug on the drain hose and allow the hydraulic fluid
to drain.

Note: In the interests of environmental protection, place plastic
sheeting and a container under the machine to collect the liquid which
drains off. Dispose of this liquid properly.

4.17.3 Unscrew the return line filter and replace the filter cartridge.

4.17.4 Install the drain plug on the drain hose.

4.17.5 Fill the hydraulic tank through the filler port with clean hydraulic fluid.

4.17.6 Bleed the hydraulic system. See section Bleeding the Hydraulic

System.

4.18 Bleeding the Hydraulic System

4.18.1 Fill the hydraulic system with clean hydraulic oil until it is visible at the
middle level or higher in the sightglass. Do not re-use used hydraulic
oil.

4.18.2 Disconnect the wire located on the fuel solenoid.

4.18.3 Crank engine 5–10 seconds. This will allow the oil to fill the inlet lines.

4.18.4 Reconnect the fuel solenoid wire.

4.18.5 Place forward/reverse control in the NEUTRAL position. Start the
engine and run the machine at idle for 3–4 minutes.

4.18.6 With the engine still running at idle, move the machine slowly back and
forth from forward to reverse for a short time to bleed air trapped in
drive circuit.

4.18.7 Switch the engine to high idle for 15–20 seconds. Return to low idle for
1 minute. Repeat 2–3 times to bleed the remaining air from the
hydraulic lines.

4.18.8 Check the hydraulic oil level and add oil as required.

Note: If the drive pump chatters or operation is noisy, turn the machine
off and check for air leaks in the inlet line of the charge pump.

Maintenance RD 16

4.22 Towing

Improper hookup and towing is hazardous and could result in injury or
death to yourself or others.

WARNING

The towing connection must be rigid, or towing must be done by two
machines of the same size or larger than the towed machine. Connect
a machine on each end of the towed machine.

Be sure that all necessary repairs and adjustments have been made
before a machine that has been towed to a service area, is put back
into operation.

These towing instructions are for moving a disabled machine for a
short distance at a low speed. Move the machine at a speed of 3 km/
h (1.9 mph) or less to a convenient location for repair. These
instructions are only for emergencies. Always haul the machine if
long distance moving is required.

Shielding must be provided on both machines. This will protect the
operator if the tow line or the tow bar breaks.

Do not allow an operator to be on the machine that is being towed
unless the operator can control the steering and/or the braking.

Before towing, make sure that the tow line or the tow bar is in good
condition. Make sure that the tow line or the tow bar has enough
strength for the towing procedure that is involved. The strength of the
towing line or the tow bar should be at least 150 percent of the gross
weight of the towing machine. This is true for a disabled machine that
is stuck in the mud and for towing on a grade.

Keep the tow line angle to a minimum. Do not exceed a 30 degree
angle from the straight ahead position.

Quick machine movement could overload the tow line or the tow bar.
This could cause the tow line or the tow bar to break. Gradual, steady
machine movement will be more effective.

Normally, the towing machine should be as large as the disabled
machine. Make sure that the towing machine has enough brake
capacity, enough weight, and enough power. The towing machine
must be able to control both machines for the grade that is involved
and for the distance that is involved.

You must provide sufficient control and sufficient braking when you are
moving a disabled machine downhill. This may require a large towing
machine or additional machines that are connected to the rear. This
will prevent the machine from rolling away out of control.

All situation requirements cannot be listed. Minimal towing machine
capacity is required on smooth, level surfaces. On inclines in poor
condition or on surfaces in poor condition, maximum towing capacity
is required.

84 wc_tx001076gb.fm

RD 16 Maintenance

Attach the towing device and machine before you release the brakes.
If the engine is running, the machine can be towed for a short distance

under certain conditions. The power train and steering system must be
operable.

The operator must steer the machine that is towed in the direction of
the tow line.

Ensure that all instructions in this section are followed carefully.

When the engine is stopped, additional steps may be required before
the machine is towed. In order to avoid damaging the power train, the
steering system, and the brakes, which may be inoperable, additional
steps may be required.

4.22.1 Block the drums in order to prevent movement of the machine. Do not
remove the blocking until the tow vehicle has been positioned and the
tow lines are in place.

4.22.2 Manually release the parking brake. This will prevent excessive wear
and damage to the braking system when towing.

4.22.3 Manually release the parking brake. See section Manually Releasing

Parking Brake.

4.22.4 Attach the tow line to the machine at the tow points.

4.22.5 Attach the tow line to the vehicle that is used to tow the disabled
machine.

4.22.6 Remove the blocks from the drums.

4.22.7 Tow the disabled machine at a slow rate of speed to the desired
location.

NOTICE: Do not tow the roller long distances or at speeds greater than
3 km/h (1.9 mph). Damage to the drive motors may occur.

4.22.8 Once the machine is at the desired location, securely block the drums.
This will prevent movement of the machine.

4.22.9 Manually re-engage the parking brake.

4.22.10 Detach the tow lines.

Maintenance RD 16

4.23 Manually Releasing Parking Brake

See Graphic: wc_gr002964

There are two drive motors on the roller—one on each drum. Each
drive motor includes a parking brake that is spring activated and
hydraulically released (SAHR).

NOTICE: To avoid damaging the internal mechanism, do not use
power tools to release or reactivate the brakes.

To manually release the brakes:
Note: Carry out the procedure on both drums.

4.23.1 Chock each drum to prevent the machine from moving.

4.23.2 Lock the articulated steering joint. See section Articulation Joint
Lockarm.

4.23.3 Using an 8mm Allen wrench, remove the plugs (a) in order to access
the release screws (b).

4.23.4 Using a 6mm Allen wrench, press and turn each release screw in until
its threads catch in the brake plate (d). Tighten each release screw
alternately until the spring (c) on each is fully compressed. You will feel
a substantial difference in the amount of torque required to turn the
screw once its spring is fully compressed.

4.23.5 Continue to tighten (turn clockwise) the two release screws to
compress the brake plate springs. Alternate back-and-forth between
the two screws, turning approximately 45° at a time, until the drums are
no longer held by the brake plate. The brake plate should release after
turning each screw approximately two (2) turns.

NOTICE: Maximum torque for the release screws is 33 Nm (24.3
ft.lbs.). Overtightening the release screws can destroy the internal
mechanism.

4.23.6 Manually turn the drum to test if the brake is released.

4.23.7 Replace the plugs, tightening them to a maximum torque of 60 ± 6 Nm
(44.2 ± 4.4 ft.lbs.).

To reactivate the brakes, carry out the following procedure on both
drums.

4.23.8 Remove the plugs (a).

4.23.9 Alternating between the two release screws (b), completely loosen
them until the brake plate is disengaged.

4.23.10 Replace the plugs, tightening them to a maximum torque of 60 ± 6 Nm
(44.2 ± 4.4 ft.lbs.).

Note: After repair, ensure that the releasing screws are back in the
normal operating postiion.
