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.

The Ride-On Trowel features a seat with an integrated "operator presence" system which works in conjunction with a throttle-mounted switch. This system allows the engine to remain running (idling) with no operator seated in the seat, as long as the throttle is not depressed.
The purpose of the "operator presence" system is to reduce the throttle to idle if the operator leaves the seat. The "operator presence" system meets requirement published by organizations such as OSHA, ANSI, and ISO.

Learning to operate the trowel

To familiarize a new operator with the Ride-On Trowel, the following steps should be taken:
1. With the operator in the seat, show him or her the functions of the steering levers (c) and how to start the machine.
2. Have the operator practice steering the trowel. A hard concrete slab slightly wetted with water is an ideal surface on which to practice.
3. Pitch the blades up approximately 6.35 mm (�") on the leading edge. Start by making the machine hover in one spot, and then practice moving the machine in a straight line and making 180� turns. The best control is achieved at full rpm.

4.5 Recommended Fuel--Gasoline

The engine requires regular grade unleaded gasoline. Use only fresh, clean gasoline. Gasoline containing water or dirt will damage the fuel system. Consult the engine owner's manual for complete fuel specifications.

Use of oxygenated fuels

Some conventional gasolines are blended with alcohol. These gasolines are collectively referred to as oxygenated fuels. If you use an oxygenated fuel, be sure it is unleaded and meets the minimum octane rating requirement.
Before using an oxygenated fuel, confirm the fuel's contents. Some states and provinces require this information to be posted on the fuel pump.
The following is the Wacker Neuson approved percentage of oxygenates:
ETHANOL - (ethyl or grain alcohol) 10% by volume. You may use gasoline containing up to 10% ethanol by volume (commonly referred to as E10). Gasoline containing more than 10% ethanol (such as E15, E20, or E85) may not be used because it could damage the engine.
If you notice any undesirable operating symptoms, try another service station, or switch to another brand of gasoline.
Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more than the percentages of oxygenates mentioned above are not covered under warranty.

4.6 Recommended Fuel--Diesel

Low temperatures cause diesel fuel to gel. Always use the proper fuel for the conditions. Follow the guidelines in the table below.

Lowest expected ambient temperature
Above freezing > 0�C (32�F)
Below freezing < 0�C (32�F)

If installing combination blades (d), orient the blades as shown in the diagram and align the screw holes. This positions the raised edge of each blade correctly for the rotation of each rotor.
If installing finish blades, simply align the screw holes. Blade orientation is not critical with finish blades.
3. Coat the screw threads with bearing grease. A grease coating will prevent wet concrete from cementing the screws in place. This step will also make blade removal easier in the future.
4. Re-install the screws and tighten securely. Do not overtighten.
The blades have now been changed.

5.10 Storage

Extended storage of equipment requires preventive maintenance. Performing these steps helps to preserve machine components and ensures the machine will be ready for future use. While not all of these steps necessarily apply to this machine, the basic procedures remain the same.

When

Prepare your machine for extended storage if it will not be operated for 30 days or more.

Preparing for storage

Perform the procedures below to prepare your machine for storage.
Complete any needed repairs. Replenish or change oils (engine, exciter, hydraulic, and gearcase) per the
intervals specified in the Scheduled Maintenance table. Grease all fittings and, if applicable, repack bearings. Inspect engine coolant. Replace coolant if it appears cloudy, is more than two
seasons old, or does not meet the average lowest temperature for your area. If your machine has an engine equipped with a fuel valve, start the engine, close
the fuel valve, and run the engine until it stops. Consult the engine owner's manual for instructions on preparing the engine for
storage.

Stabilizing the fuel

After completing the procedures listed above, fill the fuel tank completely and add a high-quality stabilizer to the fuel.
Choose a stabilizer that includes cleaning agents and additives designed to coat/protect the cylinder walls.
Make sure the stabilizer you use is compatible with the fuel in your area, fuel type, grade, and temperature range. Do not add extra alcohol to fuels which already contain it (for example, E10).
For engines with diesel fuel, use a stabilizer with a biocide to restrict or prevent bacteria and fungus growth.
Add the correct amount of stabilizer per the manufacturer's recommendations.

Storing the machine

Perform these remaining steps to store your machine. Wash the machine and allow it to dry. Move the machine to a clean, dry, secure storage location. Block or chock the
wheels to prevent machine movement. Use touch-up paint as needed to protect exposed metal against rust. If the machine has a battery, either remove or disconnect it.
NOTICE: Allowing the battery to freeze or completely discharge is likely to cause permanent damage. Periodically charge the battery while the machine is not in use. In cold climates, store and charge the battery indoors or in a warm location.
Cover the machine. Tires and other exposed rubber items should be protected from the weather. Either cover them or use a protectant.

12.1

Emission Control System Background Information
Introduction
Wacker Neuson spark-ignited engines/equipment must conform with applicable Environmental Protection Agency (EPA) emissions regulations. There are two types of emissions that fall under these regulations: 1) exhaust, and 2) evaporative. These regulations require that manufacturers warrant the emission control systems for defects in materials and workmanship.
Furthermore, EPA regulations require all manufacturers to furnish written instructions describing how to operate and maintain the engines/equipment including the emission control systems. This information is provided with all Wacker Neuson engines/equipment at the time of purchase.

Exhaust Emissions
The combustion process produces carbon monoxide, oxides of nitrogen, and hydrocarbons. Control of hydrocarbons and oxides of nitrogen is very important because, under certain conditions, they react to form photochemical smog when subjected to sunlight. Carbon monoxide does not react in the same way, but it is toxic.
Wacker Neuson utilizes lean carburetor settings and other systems to reduce the emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons.

Evaporative Emissions
Evaporative emissions are fuel emissions and generally include emissions that result from permeation of fuel through the fuel-system materials or from ventilation of the fuel system.
Wacker Neuson utilizes low-permeation fuel lines and fuel tanks where applicable to reduce evaporative emissions.

wc_tx004118gb_FM10.fm

Emission Control Systems Information and Warranty--Gasoline
Tampering and Altering
Tampering with or altering the emission control system may increase emissions beyond the legal limit. If evidence of tampering is found, Wacker Neuson may deny a warranty claim. Among those acts that constitute tampering are: Removing or altering of any part of the air intake, fuel, or exhaust systems. Altering or defeating the speed-adjusting mechanism causing the engine to
operate outside its design parameters.

Check the Cooling System
When checking the cooling system, make sure the engine is turned off and is cool. Remove the key to prevent fans from unexpectedly starting. Ensure the coolers and engine compartment are clean and free from debris, which could ignite and cause a fire. If the machine is air-cooled, be sure the cooling unit has an unobstructed air flow. If it is liquid-cooled, check coolant level (at overflow tank, if provided).
Allow radiator to cool before removing cap
slowly
WARNING! Allow the radiator to cool before checking the level. Hot radiator fluids could escape as steam and burn you. (See page 27, Engine Coolant Hazards.)

Use Caution When Fueling
WARNING! Avoid injury from fire or explosion. Never fill the fuel tank with the engine running, while smoking or when near an open flame.
Never overfill the tank or spill fuel. If fuel is spilled, clean it up immediately.
Be sure to use the correct type and grade of fuel.
Ground the fuel funnel or nozzle against the filler neck to prevent sparks that could ignite fuel vapors. Be sure to replace the fuel fill cap (if equipped) when you are done.
No smoking and no open flames in flammable/explosive
atmospheres

Prepare for Safe Operation

Ultra-Low Sulfur Diesel (ULSD) Fuel Hazard
Avoid Static Electricity Risk When Fueling
WARNING! Ultra-Low Sulfur Diesel (ULSD) poses a greater static ignition hazard than earlier diesel formulations. Avoid death or serious injury from fire or explosion; consult with your fuel or fuel system supplier to ensure the delivery system is in compliance with fueling standards for proper grounding and bonding practices.
Static discharge during fueling can cause explosion

WARNING! Exhaust fumes from diesel, gasoline or LP gas engines can kill. Do not breath exhaust fumes from any kind of engine.
Ventilate work area
Operating in Flammable/Explosive Atmospheres WARNING! A trowel must not be operated in
flammable or explosive atmospheres. Use in explosive atmospheres can result in fires and/or explosions which could cause serious injury or death.

Follow Safe Operating Practices

Do not operate in explosive/flammable
atmosphere

Prepare for Safe Operation

Avoid Crystalline Silica (quartz) Dust
WARNING! Avoid exposure to dust containing crystalline silica particles. This dust can cause serious injury to the lungs (silicosis).
Avoid silica dust
Because crystalline silica is a basic component of sand and granite, many activities at construction sites produce dust containing crystalline silica. Trenching, sawing and boring of material containing crystalline silica can produce dust containing crystalline silica. If dust which contains crystalline silica is present there are guidelines which should be followed. 1. Be aware of the health effects of crystalline silica and
that smoking adds to the damage. 2. Be aware of and follow OSHA (or other) guidelines for
exposure to airborne crystalline silica.

3. Know the work operations where exposure to crystalline silica may occur.

4. Participate in air monitoring or training programs offered by the employer.

5. Be aware of and use optional equipment controls such as water sprays, local exhaust ventilation, and enclosed cabs with positive pressure air conditioning.

6. Where respirators are required, wear a respirator approved for protection against crystalline silicacontaining dust. Do not alter the respirator in any way. Workers who use tight-fitting respirators cannot have beards/mustaches which interfere with the respirator seal to the face.

7. If possible, change into disposable or washable work clothes at the worksite; shower and change into clean clothing before leaving the worksite.

8. Do not eat, drink, use tobacco products, or apply cosmetics in areas where there is dust containing crystalline silica.

9. Store food, drink and personal belongings away from the work area.

10. Wash hands and face before eating, drinking, smok-

ing, or applying cosmetics after leaving the exposure

area.

Prepare for Safe Operation

Know the Working Area
Learn as much about your working area as possible.
Check at Ground or Floor Level
Thoroughly check the area for unusual or dangerous conditions, such as tools, or items that may damage the trowel or be propelled by the trowels rotating blades. Note where pipes and forms are located. Locate and mark protrusions (rebar, anchor bolts, floor drains, etc.) in the concrete.
Plan Your Work
Know in advance the conditions likely to be encountered, and plan for any likely emergency.
Getting on and off a Ride-On Trowel
If operating a ride-on trowel, mount and dismount carefully. Use the steps and hand holds provided. Do not use control levers as hand holds and never use guard rings as steps. Watch for surfaces that may be slippery. Never jump off a ride-on trowel.

Operating on an Elevated Deck (Multi-Story Operation)
Consult local/state regulations before you operate equipment on an elevated deck. If operating on an elevated deck, ensure perimeter safety cabling of proper size and strength is in place. Do not operate the trowel close to the edge of the deck.
Use three points of contact when mounting and
dismounting

Start Safely

Warn Personnel Before Starting
Before starting, walk completely around the machine. Make sure no one is on it or close to it. Let others know you are starting up and don't start until everyone is completely clear of the machine. As the equipment operator, you are responsible for the safe use of the machine, so always make sure you have communicated your work plans to others on the site.
Before starting, walk completely around trowel
Check the trowel thoroughly at delivery for any shipping damage. Locate the trowel in an accessible location, as close to the work site as possible. Secure the trowel after it is placed in its intended operating position so it does not tip, roll, slide or fall.

Starting the Engine
WARNING! Never attempt to start the engine by shorting across starter terminals. Serious injury or death may result.
Know the exact starting procedure for your machine. See the manufacturer's operating manual(s) for starting.
� Familiarize yourself with warning devices, gauges and operating controls.
� Make sure controls are in the neutral/locked position. � Clear the area of all persons. � Start the engine following the instructions in the
manufacturer's operating manual(s). � If necessary to run the engine or operate the machine in
an enclosed area, ensure there is adequate ventilation.
WARNING! Never operate the machine without adequate ventilation. Exhaust fumes can kill. Do not breathe exhaust fumes!
For a walk-behind (pedestrian operated) trowel machine, make sure that a circular area with a minimum radius equal to the length of the machine is clear. This will ensure safety of personnel around the machine.

Start Safely

Starting Aids If you have trouble starting the engine and need to use jumper cables, follow the instructions in manufacturer's operating manual(s). Jump-starting is a two-person operation. The operator must be in the operator's seat when jump-starting so the machine will be under control when the engine starts.
WARNING! Improper jump-starting procedures may cause serious injury or death from a battery explosion or a run-away machine. Always use proper jump-starting procedure. (See page 29, Battery Hazards.)
To avoid explosion, follow proper jumpstarting procedures
Never start engine by shorting across starter terminals

Ether/cold start fluid is HIGHLY FLAMMABLE. Before using it, always read the instructions on the ether/ cold start fluid container and the instructions in the manufacturer's operating manual(s).
WARNING! Avoid injury from explosion or fire. If the engine is equipped with a glow plug pre-heater or other intake manifold type pre-heater, follow manufacturer's instructions before using ether/cold start fluid.
After Starting Engine
Observe gauges, instruments, and warning lights to assure that they are functioning and their readings are within the operating range.
Run an Operating Check
Do not use a machine that is not in proper operating condition. It is your responsibility to check the condition of all systems and to run the check in a safe area.

Operate Safely

Walk-Behind Trowels
� Ensure that the operator is familiar with the trowel and is trained on its operation.
� Do not start or operate the trowel if the drive train will not disengage. Centrifugal force between the trowel and surface when starting can cause uncontrolled handle movement that can cause serious injury. The handle must not move while pulling the engine recoil starter.
� Visually check to be sure that the blades are free of obstructions and the area is clear for operation.
� For trowels that use this feature, ensure that the emergency stop switch is in the ON position.
� Move the throttle to the idle position. � Switch the engine ON/OFF switch to the ON position. � Never place your foot on the ring guard when starting
the engine or severe injury can occur if your foot slips through the ring guard as the blades start to spin. � While firmly holding the handle with one hand, start the engine following the guidelines in the engine manufacturer's instruction manual. � Hold the handle bar firmly with both hands while the trowel is "throttled-up".

� If control of the trowel is lost, stay clear and do not attempt to regain control until the trowel has stopped moving. Depending on the engine speed, the trowel handle can swing around before it stops completely.
Ride-On Trowels
� Ensure that the operator is familiar with the trowel and is trained on its operation.
� Ensure the operator is well rested and not fatigued, is alert, and not impaired in any way (medications, drugs, alcohol, etc.).
� Adjust the seating if necessary and get into a comfortable position where all controls are accessible.
� Visually check to be sure that the blades are free of obstructions and the area is clear for operation.
� Start the trowel following the instructions in the engine manufacturer's operation manual. For diesel powered trowels, follow the instructions for glow plug and cold start operation.
� Observe any gauges and warning lights to ensure they are functioning and their readings are within the manufacturer's normal operating range.
� Check operation of controls. Make certain they operate properly.
19

Operate Safely

Electrical Equipment
Some walk-behind trowels are powered by electric motors. Electric motors and components present special hazards during operation. Read the operator's manual. � Never operate a trowel with a damaged or worn
electrical cord. When using an extension cord, be sure to use one heavy enough to carry the current load. When trowel is used outdoors, use only extension cords that are marked for outdoor use. � Use only appropriate extension cords that have grounding-type plugs and receptacles that accept the machine's plug. � Use an electrically powered trowel that has been built in accordance with the requirements of the National Electrical Code (NFPA-70) and has been approved by a Nationally Recognized Test Lab.

� Keep all electrical cords away from rotating components, heat, oil, and sharp edges to avoid damaging them.
� Avoid body contact with grounded surfaces such as pipes, metal railings, radiators and metal ductwork.
� Always check the power supply before running the trowel. Using the wrong voltage supply will damage the motor.
� Always make sure the motor switch is OFF or in the stop position before plugging the trowel into the power supply.
� Do not operate an electric powered trowel in the rain or snow. Keep the motor, switch, and electrical cords dry.
� Never operate the trowel in areas exposed to flammable or explosive liquids or gases. Sparks could ignite fumes.

Shut Down Safely

Common Maintenance Safety Practices
Use Proper Ventilation Never run an engine in an enclosed area without an approved ventilation system.
Ventilate work area
WARNING! Exhaust fumes contain carbon monoxide which could be deadly if inhaled. Never operate any type of engine without proper ventilation. EXHAUST FUMES CAN KILL. A feeling of tiredness, or nausea, is an indication of being overcome by exhaust. Shut the engine off immediately if this occurs.

Fuel Hazards
WARNING! Avoid serious injury or death. Always use approved fuel containers and/or fuel dispensing equipment to reduce the risk of explosion or fire.
Always observe these practices to reduce the possibility of a serious accident: � Shut off engine and ignition during refueling. � Turn off all electrical switches. � Ground the fuel nozzle against the filler neck. � Keep sparks and open flames away from fuel. Do
not smoke while refueling or when handling fuel containers. � Do not cut or weld on or near fuel lines, tanks or containers. � Do not overfill the tank or spill fuel. Clean up spilled fuel immediately. Clean spills immediately.
No smoking and no open flames

Perform Maintenance Safely

Ultra-Low Sulfur Diesel (ULSD) Hazard
WARNING! Ultra-Low Sulfur Diesel (ULSD) poses a greater static ignition hazard than earlier diesel formulations with higher sulfur content. Avoid death or serious injury from fire or explosion; consult with your fuel or fuel system supplier to ensure the delivery system is in compliance with fueling standards for proper grounding and bonding practices.
Engine Coolant Hazards
WARNING! Avoid serious injury or death. Liquid cooling systems build up pressure as the engine gets hot, so use extreme caution before removing the radiator cap. � Stop the engine and wait for the system to cool. � Wear protective clothing and safety glasses. � Turn the radiator cap slowly to the first stop to allow
the pressure to escape before removing completely.

Engine Coolant Hazards (cont.) CAUTION! Before replacing engine coolant, refer to
the manufacturer's operating manual(s) for direction. Using incorrect coolant type may cause overheating and increase safety risks.
Hydraulic System Hazards Be sure to follow manufacturer's instructions for relieving fluid pressure before performing any maintenance. The hydraulic system is pressurized whenever the engine is on and may hold pressure even after the engine is shut off. Cycle hydraulic controls, including auxiliary hydraulic control (if equipped), after the engine is shut off.
Check for leaks and inspect
hoses

Allow radiator to cool before removing cap
slowly
27

Perform Maintenance Safely

Hydraulic System Hazards (cont.)
During inspection of the hydraulic system: � Wait for fluid to cool before disconnecting the lines
Hot hydraulic fluid can cause severe burns. � Wear appropriate eye protection. Hydraulic fluid can
cause permanent eye injury. � When venting or filling the hydraulic system, loosen
the filler cap slowly and remove it gradually. � Never reset any relief valve in the hydraulic system
to a pressure higher than recommended by the manufacturer.
Hydraulic Fluid Injection Hazard
WARNING! Accidental injection of pressurized fluid into the hands or body is dangerous and could result in death or serious injury. Use caution when checking hydraulic leaks as pressurized hydraulic fluid has enough force to penetrate skin, causing serious personal injury.
If a leak is discovered: � Ensure engine is turned off; relieve pressure in
hydraulic circuit. � Wear proper hand and eye protection.
28

� Visually examine the hydraulic hoses or fluid lines in the vicinity of the leak for breaks or cracks. Do not use your hand to check for leaks.
� Repair or replace hydraulic lines according to the manufacturer's recommendations.
Fluid injection injuries are not always obvious. Victims have reported such injuries feel like a bee sting or splinter under the skin. If you suspect you have a fluid injection injury, do not take chances. Seek proper medical care immediately. If any fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this type of injury.
Wear eye protection
Pressurized fluid can inject into the body

Perform Maintenance Safely

Battery Hazards
The liquid in batteries contains acid, which is a POISON and could cause SEVERE CHEMICAL BURNS.
Avoid injury: � Wear a face shield to prevent contact with your eyes. � Wear chemical-resistant gloves and clothing to keep
electrolyte off your skin and regular clothing.
WARNING! Electrolyte will damage eyes or skin on contact. Always wear a face shield to avoid electrolyte in eyes.
If liquid from the battery contacts your eyes, flush immediately with clean water and get medical attention. Wear chemical-resistant gloves and protective clothing to keep liquid off your skin. If liquid contacts exposed skin or clothing, wash off immediately with clean water. If liquid is ingested, drink large quantities of water or milk. DO NOT induce vomiting. Seek medical attention immediately.

Wear hand protection
