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

• Personal injury from improper lifting techniques

4.23 Direction and Speed

See Graphic: wc_gr002953

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.

Operation RD 12A

4.24 Transmission

See Graphic: wc_gr002953

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.

5.10 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.

RD 12A Maintenance

5.11 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.

wc_tx001557gb.fm 63

Maintenance RD 12A

5.12 Hydraulic Oil Level

See Graphic: wc_gr005894

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.

5.13 Hydraulic Suction Strainer

See Graphic: wc_gr005894

A hydraulic strainer (14) is located in the hydraulic tank. This strainer will not normally require service and does not need to be replaced when changing the hydraulic oil.

RD 12A Maintenance

5.14 Changing the Hydraulic Oil & Filter

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.

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

5.14.2 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.

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

5.14.4 Install the drain plug on the drain hose.

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

5.14.6 Bleed the hydraulic system. See section Bleeding the Hydraulic

System.

5.15 Bleeding the Hydraulic System

5.15.1 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.

5.15.2 Disconnect the spark plug wires to prevent the engine from starting.

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

5.15.4 Reconnect the spark plug wires.

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

5.15.6 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.

5.15.7 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.

5.15.8 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.

5.16 Long-Term Storage

If machine is to be stored for more than 30 days:

wc_tx001557gb.fm 65

Maintenance RD 12A

• Drain the fuel tank and drain the water tank. If ballast was added to the rear drum, also drain the rear drum.

• Change the engine oil.

• Remove the spark plugs and pour approximately 3 ml (1 ounce) of SAE 30W oil into each engine cylinder through the spark plug opening.

• Re-install the spark plugs. Leave the ignition wires disconnected to prevent the engine from starting. Crank the engine for one or two seconds to distribute the oil inside the engine cylinders. Connect the ignition wires.

• Clean the entire roller and engine compartment.

• Remove dirt from the cooling fins on the engine cylinders and on the blower housing.

• Set the lockarm to secure the roller halves together.

• Remove the battery from the machine and charge it periodically.

• Cover the entire machine and place it in a dry, protected area.

5.17 Towing Bypass Valve

See Graphic: wc_gr002960

The drive circuit is equipped with a towing valve (43) to allow oil to bypass the drive motors and let the roller freewheel for towing.

The towing valve should be used in emergency cases where the machine has become bogged down in loose or muddy soil, or cannot be driven due to an engine or hydraulic system failure.

With the towing valve open, the drive circuit has no braking action and the machine will roll freely. Apply the brake or attach the towing device

WARNING

before opening the towing valve. Close the towing valve immediately after the towing operation is complete to prevent the machine from rolling unexpectedly.

To open the bypass, shut the engine off and rotate the shaft on the towing valve counter-clockwise.

When resuming machine operation, make sure the bypass is closed by rotating the shaft on the towing valve clockwise.

wc_tx001557gb.fm 67

Maintenance RD 12A

5.18 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.

68 wc_tx001557gb.fm

RD 12A 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.

5.18.1 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.

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

5.18.3 Open bypass valve. See section Bypass Valve.

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

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

5.18.6 Remove the blocks from the drums.

5.18.7 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.

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

5.18.9 Close the bypass valve.

5.18.10 Manually re-engage the parking brake.

5.18.11 Detach the tow lines.

SERVICING BATTERIES Always wear safety glasses and gloves when

working with batteries. Before removing a battery, turn off all electrical

equipment,then disconnect the negative (-) battery cable first. Before installing a battery, turn off all electrical equipment,then connect the positive (+) battery cable first.

To prevent sparking at the posts when using a battery charger,always turn the charger off or disconnect it from its power source before connecting or disconnecting charger leads to battery posts. Caps on all cells should be left on and the vent caps would be covered with a wet cloth.

Do not short across the battery terminals. The spark could ignite the gases.

BOOSTER CABLE INSTRUCTIONS (FIG.39)

1. Connect positive (+) cable to positive post of discharged battery.

2. Connect other end of same cable to same marked post of booster battery.

3. Connect negative (-) cable to other post of booster battery.

4. Make final connection on stalled vehicle away from battery,either on vehicle frame or engine block.

5. Star t vehicle and remove cables in reverse order of connection.

BATTERY SERVICING To prevent a battery explosion: (Fig. 40)

• Maintain the electrolyte at the recommended

level.Check level frequently. Add distilled water to batteries only before starting up,never when shutting down. With electrolyte at the proper level,less space is available for gases to accumulate in the battery.

• Use a flashlight to check the electrolyte level.

Never use a flame. (Fig. 41)

• Do not short across the battery terminals.

The spark could ignite the gases.

Battery acid will burn skin, eat holes in clothing, and may cause blindness if splashed into eyes.If you spill acid on yourself flush skin immediately with lots of water. Apply baking soda to help neutralize the acid. If acids gets in your eyes,flush immediately with large amounts of water and seek proper medical treatment immediately.

When servicing batteries,remember that a lead-acid storage battery generates (when charging or discharging) hydrogen and oxygen – a very explosive mixture. A spark of flame could ignite these gases.

HYDRAULIC SYSTEMS NOTE: Hydraulic Systems have “special features”.

Some of the features affecting your safety are listed below.

Pressure can be maintained in hydraulic and air circuits long after the engine has been shut down. This pressure can cause hydraulic fluid or items such as pipe plugs to “shoot out” at high speed if pressure is not released correctly.Release system pressure before attempting to make adjustments or repairs.

Consult the manufacturer’s instructions for correct procedure.

Before disconnecting hydraulic fluid lines, be sure you:

• Shut off engine.

• Always release any air pressure (supercharge)

on the hydraulic reservoir.

• Move pedals and control levers repeatedly

through their operating ranges to relieve all pressures.

Pressurized hydraulic fluid can penetrate the skin and cause serious injury. Therefore, be sure all connections are tight and that lines,pipes,and hoses are in good condition before starting the engine.

Fluid escaping from a small hole can be almost invisible.Use a piece of cardboard or wood, instead of your hands,to search for suspected leaks.(FIG. 42)

HYDRAULIC SYSTEMS (CONT’D) If you are struck by escaping hydraulic fluid

under pressure,serious injury can occur if

proper medical treatment is not administered immediately.

During operation,hydraulic fluid and air in an unvented hydraulic tank becomes heated and will tend to expand. This will raise the pressure inside an unvented hydraulic tank.If the filler cap is removed rapidly,the pressure in the tank can force the oil out of the tank very rapidly.The hydraulic fluid may be very hot and may cause severe burns.Always relieve tank pressure before removing the cap completely.Consult the manufacturer’s instructions for the correct procedure.

When adding fluid to any system,be sure to use the fluid recommended by the manufacturer. Certain fluids, when mixed, may destroy seals causing loss of control and possible personal injury.

Keep hydraulic relief valve settings set to the manufacturer’s recommendations.Excessive pressures could result in structural or hydraulic failures.Low pressure could result in loss of control.Either condition could cause

personal injury or death. Be sure the engine is stopped and machine is

properly locked out and controls tagged,before working on a machine.Only run engine when it is essential,as in the case o f pressure adjustments, lubrication,or tests. Follow the manufacturer’s recommendations when making adjustments. Never resume operation until satisfactory adjustments have been made.The operator must follow the mechanic’s instructions when adjustments are being made or machine is being serviced.

TIRE INSPECTION

Recommended air pressure must be maintained in every tire.Daily checks assure that inflation is correct.If your periodic check discloses a tire that is continuously losing air, a leak is indicated and must be repaired.(FIG. 43)

During your pressure checks,also inspect for :

• Objects wedged between or embedded in tires.

• Missing valve caps and wheel lugs.

• Cuts, tears, and breaks that may need repair.

• Abnormal or uneven wear.

• Damaged or poor fitting rim or rim flanges.

• Projecting body hardware, loose fender bolts,

spring clips – anything that could contact a tire.

Do not burn or weld on wheels or rims.

PNEUMA TIC TIRES

Changing tires or adding air can be a hazardous business.Special tools and procedures are required for changing off-highway tires.

Explosion and separation of a tire and/or rim parts can cause serious injury or death. (FIG. 44) Always follow the manufacturer’s recommendations or see your tire supplier.

PERFORM MAINTENANCE SAFELY

TIRE PRESSURE

Check tire pressure before starting operation. An air pressure rise during operation is normal and should NOT be reduced.Overloads or overspeeds may produce increased tire pressures d ue to heat.Never bleed tires.Reduce your load – or speed – or stop until tires cool.

ADD AIR

From a distance – with air chuck clipped on the tire valve – and with extension hose that permits you to stand behind tread.(FIG. 45) Always use a tire cage or equivalent for protection.

ROPS (Roll-Over Protective Structures)

Periodically inspect ROPS for cracks and loose mounting hardware.

Replace all missing,deteriorated or worn rubber parts. If it becomes necessary to remove a ROPS,reinstall it only

on the same machine, in its original position. (FIG. 46) NEVER alter the ROPS in any way without the written

approval of the manufacturer. NEVER cut holes in or weld on ROPS without the

manufacturer’s approval. NEVER attempt to repair a damaged ROPS – it must be

replaced with a new unit,approved for that machine. Periodically inspect seat belts for wear, tear,deterioration

or excessive dirt.Replace them if necessary.

AIR CONDITIONERS

NEVER attempt to weld on or near air conditioners. Poisonous gas may be formed when refrigerant gas is exposed to a flame or excessive heat.

Maintenance and repair of air conditioners … except for very minor repairs or servicing … must be done only by an experienced air conditioner or refrigeration technician. (FIG.47)
