1.2 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 of
the 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.

Only trained personnel are permitted to start, operate, and shut down the machine.
They also must meet the following qualifications:
have received instruction on how to properly use the machine
are familiar with required safety devices
The machine must not be accessed or operated by:
children
people impaired by alcohol or drugs
Personal
Protective
Equipment
(PPE)
Wear the following Personal Protective Equipment (PPE) while operating this
machine:
Close-fitting work clothes that do not hinder movement
Safety glasses with side shields
Hearing protection
Safety-toed footwear
Never operate this machine in applications for which it is not intended.
Do not allow anyone to operate this equipment without proper training. People
operating this equipment must be familiar with the risks and hazards associated
with it.
Do not touch the engine or muffler while the engine is on or immediately after it
has been turned off. These areas get hot and may cause burns.
Do not use accessories or attachments that are not recommended by Wacker

Do not leave the machine running unattended.
Do not run the machine indoors or in an enclosed area such as a deep trench
unless adequate ventilation, through such items as exhaust fans or hoses, is
provided. Engine exhaust contains carbon monoxide. This is a poison you
cannot see or smell. Exposure to carbon monoxide can cause loss of
consciousness and CAN KILL YOU IN MINUTES.
ALWAYS remain aware of moving parts and keep hands, feet, and loose
clothing away from the moving parts of the machine.
Always wear protective clothing appropriate to the job site when operating the
machine.
Read, understand, and follow procedures in the Operator’s Manual before
attempting to operate the machine.

1.4 Operator Safety while Using Internal Combustion Engines
Operating
safety
When running the engine:
Keep the area around 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.
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.
fRead 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.
fNEVER operate the machine inside an enclosed area, such as a tunnel, unless

1.5 Service Safety
Personal
Protective
Equipment
(PPE)
Wear the following Personal Protective Equipment (PPE) while servicing or
maintaining this machine:
Close-fitting work clothes that do not hinder movement
Safety glasses with side shields
Hearing protection
Safety-toed footwear
In addition, before servicing or maintaining the machine:
Tie back long hair.
Remove all jewelry (including rings).
Do not attempt to clean or service the machine while it is running. Rotating parts
can cause severe injury.
Do not crank a flooded engine with the spark plug removed on gasoline-
powered engines. Fuel trapped in the cylinder will squirt out the spark plug
opening.
Do not test for spark on gasoline-powered engines if the engine is flooded or the
smell of gasoline is present. A stray spark could ignite the fumes.
Do not use gasoline or other types of fuels or flammable solvents to clean parts,
especially in enclosed areas. Fumes from fuels and solvents can become
explosive.
ALWAYS turn engine off and remove key from machine before performing
maintenance or making repairs.
Handle blades carefully. The blades can develop sharp edges which can cause
serious cuts.
Keep the area around the muffler free of debris such as leaves, paper, cartons,
etc. A hot muffler could ignite the debris and start a fire.
When replacement parts are required for this machine, use only Wacker
Neuson replacement parts or those parts equivalent to the original in all types of
specifications, such as physical dimensions, type, strength, and material.
Disconnect the spark plug on machines equipped with gasoline engines, before
servicing, to avoid accidental start-up.
ALWAYS switch off the power supply at the battery disconnect before adjusting
or maintaining the electrical equipment.
Keep the machine clean and labels legible. Replace all missing and hard-to-
read labels. Labels provide important operating instructions and warn of
dangers and hazards.
WARNING
A poorly maintained machine can become a safety hazard! In order for the
machine to operate safely and properly over a long period of time, periodic
maintenance and occasional repairs are necessary.
