Machine Description and Intended Use

This machine is a ride-on concrete finishing trowel. The Wacker Neuson Ride-On
Trowel consists of a frame onto which are mounted a gasoline or diesel engine, a
fuel tank, a water tank, two gearboxes joined by a drive shaft, and an operator’s
platform with controls and a seat. A set of metal blades is connected to each
gearbox. A ring guard surrounds the blades. The engine rotates the blades via the
gearboxes and a clutch mechanism. The rotating blades ride on the surface of
curing concrete, creating a smooth finish. The operator, who sits on the operator’s
platform, uses the controls and the throttle pedal to control speed and direction ofthe machine.

This machine is intended to be used for floating and burnishing curing concrete.
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 finish inappropriate materials such as slurries, sealers, or
epoxy finishes
 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
 Chemical burns from the curing concrete
 Fire hazards from improper refueling techniques
 Fuel and its fumes, fuel spillage from improper lifting technique
 Personal injury from improper lifting techniques
 Cutting hazards from sharp or worn blades
To protect yourself and others, make sure you thoroughly read and understand the
safety information presented in this manual before operating the machine.

from the moving parts of the machine.

Dust precaution
Dust created by construction activities may cause silicosis or respiratory harm. To
reduce the risk of exposure:
 Work in a well ventilated area.
 Use a dust control system.
 Wear an approved dust/particle respirator.

Storing the machine

 Store the machine properly when it is not being used. The machine should be
stored in a clean, dry location out of the reach of children.
 Close the fuel valve when the machine is not being operated.

Lifting and Transport Safety

Requirements Before lifting the machine:
 refer to Technical Data for the operating weight of the machine
 make sure the lifting devices have sufficient capacity to lift the machine safely
 make sure the winch, forklift, or crane to be used for lifting the machine is in
operable condition and designed for such work

Operator Safety while Using Internal Combustion Engines

WARNING
Internal combustion engines present special hazards during operation and fueling.
Failure to follow the warnings and safety standards could result in severe injury or death.
► Read and follow the warning instructions in the engine owner’s manual and the
safety guidelines below

DANGER

Exhaust gas from the engine contains carbon monoxide, a deadly poison.
Exposure to carbon monoxide can kill you in minutes.
► NEVER operate the machine inside an enclosed area, such as a tunnel, unless
adequate ventilation is provided through items such as exhaust fans or hoses.

Operating safety

When running the engine:
 Keep the area around the exhaust pipe free of flammable materials.
 Check the fuel lines and the fuel tank for leaks and cracks before starting the
engine. Do not run the machine if fuel leaks are present or the fuel lines are
loose.
When running the engine:
 Do not smoke while operating the machine.
 Do not run the engine near sparks or open flames.
 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.
 Re-install the fuel tank cap after refueling.
 Use suitable tools for refueling (for example, a fuel hose or funnel).
When refueling the engine:
 Do not smoke.
 Do not refuel a hot or running engine.
 Do not refuel the engine near sparks or open flames

Radiator Safety

Do not remove the radiator cap when the engine is running or hot. The radiator
fluid is hot and under pressure and may cause severe burns!


Liquid Propane (LP) Safety

WARNING
Fire, asphyxiation, chemical burn, and explosion hazards. Liquid propane (LP)
presents special hazards during operation and fueling. Failure to follow the
warnings and safety standards could result in serious injury or death.
► Read and follow the safety instructions in the engine owner’s manual and the
safety guidelines below.

Handling LP

Observe the following safety instructions when handling LP.
 Use proper lifting techniques to prevent stress or strain injuries.
 LP cylinders are pressurized. To vent excess pressure, two relief valves exist in
the fueling system for this machine. Read and understand the topic “Relief
Valves” in the Operation chapter before operating the machine.
 Pressurized LP is extremely cold. Vapors can instantly freeze bare skin and
eyes. Always wear gloves and eye protection when handling LP cylinders.
 LP vapors are heavier than air. LP vapors may settle around you, reducing the
amount of oxygen necessary for breathing. Always handle LP cylinders in a
well-ventilated area.
 Do not use an LP cylinder if there is visible damage to the tank or valves.
 Use only LP cylinders that have been filled by a trained and authorized person.

Responding to hazardous situations

Follow the safety instructions below if a hazardous situation occurs while you are
operating this machine (for example: a fire, explosion, severe weather, etc.).
 Stop the engine.
 Remove the starting key.
 Leave the work area.
 Notify local emergency response services.

Storing and Transporting LP Cylinders

Follow the safety instructions below when storing and transporting LP cylinders.
 Store and transport LP cylinders in the upright position only.
 Do not drop LP cylinders or allow them to roll or bounce in transit.
 Do not store or transport LP cylinders in environments where the temperature
may reach 51°C (125°F), for example, in a closed truck bed.
 Empty LP cylinders may contain residual pressurized gas and must be stored
and transported under the same conditions as full LP cylinders

Replacing Empty LP Cylinders

Follow the safety instructions below when replacing empty LP cylinders.
 Only a person familiar with the process should replace empty LP cylinders.
 Replace empty LP cylinders only in a well-ventilated area.
 Do not replace empty LP cylinders near sparks or open flames.
 Do not replace empty LP cylinders while the engine is running.
 Do not allow LP cylinders to remain in direct sunlight for extended periods
during the replacement process.
 Ensure that the full LP cylinder is properly seated and fastened in the tank
clamps.
 Ensure that all hose connections are tight, and perform a leak test, before
opening the discharge valve.
