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

RD 12A Operation
4.3 Preparing the Machine for First Use
Preparing for first use
To prepare your machine for first use:
4.3.1 Make sure all loose packaging materials have been removed from the
machine.
4.3.2 Check the machine and its components for damage. If there is visible
damage, do not operate the machine! Contact your Wacker Neuson
dealer immediately for assistance.
4.3.3 Take inventory of all items included with the machine and verify that
all loose components and fasteners are accounted for.
4.3.4 Attach component parts not already attached.
4.3.5 Add fluids as needed and applicable, including fuel, engine oil, and
battery acid.
4.3.6 Move the machine to its operating location.
4.4 Position of the Operator
Safe and efficient use of this machine is the operator’s responsibility.
Full control of the machine is not possible unless the operator
maintains the proper working position at all times.
While operating this machine, the operator must:
• be seated in the operator’s seat facing forward
• wear the seat belt, properly adjusted and latched
• have both feet on the control deck
• have one hand on the steering wheel at all times
• have the other hand free to operate the controls as needed
4.5 Recommended Fuel
The engine requires regular grade unleaded gasoline. Use only fresh,
clean gasoline. Gasoline containing water or dirt will damage fuel
system. Consult engine owner’s manual for complete fuel
specifications.

Operation RD 12A
4.6 Roll Over Protection Structure (ROPS)
The machine is equipped with a Roll Over Protection Structure
(ROPS). The machine is normally delivered to the customer with the
ROPS folded forward to facilitate transport.
Do not use the machine without the ROPS in place. The ROPS is
designed to protect the operator in a rollover accident.
WARNING
Before using the machine, position the ROPS in the fully upright
position as follows:
4.6.1 Support the ROPS using a crane and suitable rigging capable of
supporting 43 kg (95 lbs.).
NOTICE: Do not use the ROPS to lift the machine.
4.6.2 Remove the shipping strap from both sides of the frame. Save the
washers.
4.6.3 Loosen the bottom mounting bolt on both sides.
4.6.4 Rotate the ROPS into the upright position.
4.6.5 Secure the ROPS to the frame using the saved washers and the
supplied bolts. Torque hardware to 106 Nm (78 ft.lbs.).
Each month, check the torque on all of the screws holding the ROPS
in place. Check that the ROPS frame is not rusty, cracked, broken, or
damaged in any way.
Change the seat belts every 3 years, or any time they have been
subjected to accident-level loads.
If the ROPS has been removed from the machine, it must be
reinstalled before the machine is used. When reinstalling the ROPS,
use the original nuts and bolts and tighten the bolts to the specified
torques.
Do not weld or drill into the ROPS. Drilling or welding on the ROPS will
nullify the ROPS certification.

4.7 Foldable Roll Over Protection Structure (ROPS) (if equipped)
See Graphic: wc_gr002957
The machine is equipped with a Roll Over Protection Structure
(ROPS). The machine is normally delivered to the customer with the
ROPS folded forward to facilitate transport.
Do not use the machine without the ROPS in place. The ROPS is
designed to protect the operator in a rollover accident.
WARNING
Before using the machine, position the ROPS in the fully upright
position as follows:
4.7.1 Support the upper mass ROPS using a crane and suitable rigging
capable of supporting 19 kg (42 lbs.).
NOTICE: Do not use the ROPS to lift the machine.
4.7.2 Remove the safety pin (a) and pull out the locking pin (b). Do so on
both sides.
4.7.3 Lift the ROPS into the upright position.
4.7.4 Insert the locking pins and secure them with the safety pins.
Be aware of pinch points when lowering and raising the ROPS.
WARNING
To lower the ROPS:
4.7.5 Support the upper mass of the ROPS using a crane and suitable
rigging capable of supporting 19 kg (42 lbs.).
4.7.6 Remove the safety pin (a) and pull out the locking pin (b). Do so on
both sides.
4.7.7 Gently lower the upper mass.
Note: When lowering ROPS, do not allow the upper frame to fall into
the lower position. Allowing the upper mass to slam will weaken the
ROPS system and ultimately compromise its integrity and protection.
4.7.8 Insert the pins in the ROPS in the lower hole setting through the upper
mass to secure it for transport.
Each month, check the torque on all of the screws holding the ROPS
in place. Check that the ROPS frame is not rusty, cracked, broken, or
damaged in any way.
Keep the ROPS in the extended (upright) position when using the
roller, and always use the seat belts provided.
Change the seat belts every 3 years, or any time they have been
subjected to accident-level loads.
