1.2 Machine Description and Intended Use

This machine is a dual drum, ride-on roller. The Wacker Neuson Ride-On 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

 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.

1.6 Operator Safety while Using Internal Combustion Engines

Operating

safety

When running the engine:

 Do not touch the engine or muffler while the engine is running or immediately

after it has been turned off.

 Do not operate a machine when its fuel cap is loose or missing.

 Do not start the engine if fuel has spilled or a fuel odor is present. Move the

machine away from the spill and wipe the machine dry before starting.

Refueling

safety

When refueling the engine:

 Clean up any spilled fuel immediately.

 Refill the fuel tank in a well-ventilated area.

 Replace the fuel tank cap after refueling.

 Use suitable tools for refueling (for example, a fuel hose or funnel).

RD 16 Safety Information

1.7 Hydraulic Fluid Safety

Safety

instructions

 Inspect the hydraulic system thoroughly before operating the machine.

 Do not touch hydraulic fluid or hydraulic components while the machine is

operating. Wait until the machine is cool.

 Before disconnecting hydraulic fittings or hoses, ensure that all pressure has

been bled from the circuit. Set all controls in neutral, turn engine off, and allow

the fluids to cool before loosening hydraulic fittings or attaching test gauges.

 Hydraulic fluid escaping under high pressure may penetrate the skin, cause

burns, blind, or cause other serious injuries or infections. Contact a physician

immediately for treatment if your skin has been penetrated by hydraulic fluid,

even if the wound seems minor.

 Fluid leaks from small holes are often practically invisible. Do not use your bare

hands to check for leaks. Check for leaks using a piece of cardboard or wood.

 Hydraulic fluid is extremely flammable. Stop the engine immediately if a

hydraulic leak is detected.

 After servicing the hydraulics, make sure all components are reconnected to the

proper fittings. Failure to do so may result in damage to the machine and/or

injury to a person on or near the machine.

1.8 Safety Guidelines for Lifting the Machine

When lifting the machine:

 Make sure slings, chains, hooks, ramps, jacks, forklifts, cranes, hoists, and any

other type of lifting device used is attached securely and has enough weight-

bearing capacity to lift or hold the machine safely. See section Technical Data

for machine weight.

 Remain aware of the location of other people when lifting the machine.

 Only use the lifting points and tie-downs described in the Operator’s Manual.

 Make sure the transporting vehicle has sufficient load capacity and platform size

to safely transport the machine.

To reduce the possibility of injury:

 Do not stand under the machine while it is being lifted or moved.

 Do not get onto the machine while it is being lifted or moved.

WARNING

Possibility of severe injury. Hydraulic fluid is under high pressure and becomes very

hot during operation.

f To avoid injury, obey the safety instructions listed below.
