1.2Machine 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 rema in even after protective measures have been t aken.
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

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. This system meets all safety requirements
and eliminates the need for a foot-operated “kill switch”.
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 control arms
(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 place for an operator to practice with the machine.
For this practice, pitch the blades up approximately ¼" on the leading edge.
Start by making the machine hover in one spot, and then practice driving the
machine in a straight line and making 180° turns. The best control is achieved
at full rpm.

CRT 36Operation
3.2Position of the Operator
Safe and efficient use of this machine is the op erator’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
have both feet on the control deck
have both hands on the controls
3.3Preparing the Machine for First Use
1. Make sure all loose packaging materials have been removed from the machine.
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.
3. Take inventory of all items included with the machine and verify that all loose
components and fasteners are accounted for.
4. Attach component parts not already attached.
5. Add fluids as needed and applicable, including fuel, engine oil, and battery acid.
6. Move the machine to its operating location.
3.4Recommended Fuel
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.
wc_tx000639gb.fm
23
OperationCRT 36
3.5Break-in Period
1. To break in the gearboxes, run the engine at 50% of full throttle for the first 2–4
hours. This will prevent premature wear and extend gear life.
NOTICE: Running the engine at full throttle during the break-in period could result
in premature gear failure.
2. Verify that the horizontal blade pitch links are properly assembled. When
seated on the machine, the right rotor should have an “R” designation located
towards the upper portion of the pitch link and the left rotor should have an “L”.
3.6Before Starting
Before starting the trowel, check the following:
fuel level
oil level in the engine
condition of the air filter
condition of trowel arms and blades
Grease the trowel arms daily.
wc_gr001252
24
wc_tx000639gb.fm
CRT 36Operation
3.7Starting
Before starting the operator must know the location and function of all controls.
1. Push down on the throttle foot pedal, turn the engine keyswitch (o), and hold it
until the engine starts.
Note: If the engine is cold, pull out the choke control knob fully. The choke may
need to be opened even when starting a warm engine.
NOTICE: Cranking the engine for more than 5 seconds can cause st arter damage.
If the engine fails to start, release the keyswitch and wait 10 seconds before
operating the starter again.
Note: The engine has an oil alert light to notify operator if the oil pressure is low. If
engine will not start, or stops during operation, check engine oil level.
2. Allow the engine to warm up before operating the trowel.
3.8Stopping
To stop trowel movement, return control levers to their neutral position and release
pressure on the throttle foot pedal.
To stop the engine, turn the keyswitch to “O” (off).
3.9Operation
To utilize your Wacker Neuson Ride-On Trowel to its fullest capacity, the machine
should be driven in the direction that the operator is facing. This will finish the
widest possible area, while giving the operator an excellent view of the slab surface
about to be troweled. When the machine reaches the end of the slab, make a 180°
U-turn, and repeat the straight line of direction to the other end of the slab.
Note: During the break-in period, run the engine at 50% of full throttle. Refer to
Section New Machines.
NOTICE: DO NOT use excessive pressure on the control levers. Excessive
pressure does not improve the reaction time of the machine and can damage the
steering controls.
NOTICE: Attempting to use the trowel too early in the curing stage of the concrete
may result in an undesirable finish. Only experienced concrete finishers should
operate the trowel.

plug (b). If the level is below the threads of the oil fill plug hole, add synthetic gear
oil through the opening. DO NOT overfill. Wipe the threads dry on both the gearbox
and the oil fill plug, apply Loctite 545 or equivalent to the oil fill plug threads,
replace the oil fill plug and torque to 16–20 Nm (12–15 ft.lbs.).
NOTICE: DO NOT mix types of gear oil. DO NOT overfill the gearbox with oil.
Damage to the gearbox may occur if oils are mixed, or if the gearbox is overfilled.
See Technical Data for oil quantity and type.
To change gearbox oil:
1. Place a container of sufficient capacity (approximately 3.8 l [1 gallon]) under
each gearbox.
2. Remove the gearbox oil drain plug (c) and allow the oil to drain out. It may be
necessary to remove the gearbox oil fill plug(s) to facilitate draining. After most
of the oil has drained out, tip the back of the trowel upwards to allow the
remaining oil to drain out.
3. After all the oil has drained out, wipe the threads dry on both the gearbox and
the oil drain plug, apply Loctite 545 or equivalent to the oil drain plug threads,
and replace the gearbox oil drain plug.
Note: Dispose of used gear oil in accordance with environmental protection
legislation.
4. With the trowel level, fill the gearbox with approximately 1.83 l (62 oz.) synthetic
gear oil through the oil fill plug as described above.
5. Wipe the threads dry on both the gearbox and the oil fill plug, apply Loctite 545
or equivalent to the oil fill plug threads, replace the oil fill plug(s), and torque all
plugs to 16-20 Nm (12–15 ft.lbs.).
Each gearbox has a pressure relief valve (a) which can become clogged over
time. Check or replace as needed. Failure to replace the valve can result in oil
leakage from the gearbox shaft seals.

Emission Control Systems Information and Warranty—Gasoline
6Emission Control Systems
Information and Warranty
—Gasoline
The Emission Control Warranty and associated information is valid only for the
U.S.A., its territories, and Canada.
6.1Emission Control System Background Information
Introduction
Wacker Neuson spark-ignited engines/equipment must conform with applicable
Environmental Protection Agency (EPA) and the State of California 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 and California regulations require all manufacturers to furnish
written instructions describing how to operate and maintain the e ngines/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.
Problems that may affect Emissions
If any of the following symptoms arise, have the engine/equipment inspected and
repaired by a Wacker Neuson dealer/service center.
Hard starting or stalling after starting
Rough idling
Misfiring or backfiring under load
Afterburning (backfiring)
Presence of black exhaust smoke during operation
High fuel consumption
wc_tx001754gb.fm47
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 tamp ering 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.

PREPARE FOR SAFE OPERATION
Trowel.qxd 11/24/04 10:18 AM Page 7
PRE-OPERATIONAL CHECKS
Walk around the trowel. Carefully inspect for
evidence of physical damage, such as cracks,
bends, or deformation of plates and welds. Check
for loose, broken or missing parts on the trowel,
including brackets, vibration isolators, nuts and
bolts. Hardware should be replaced with original
equipment manufacturer’s (OEM) parts, and should
be properly tightened to the manufacturer’s
recommendations.
Remove all trash and debris from the trowel. Make
sure oily rags, leaves, or other flammable material
are removed and not stored on the trowel. Avoid
potential fire hazards!
Clean all oil or grease
from operator areas such
as control handles, foot
pedals, or platforms to
prevent slipping.
Check for fuel, oil, and
hydraulic fluid leaks. All
leaks must be corrected
before the trowel is
operated.
Inspect all hydraulic hoses for cracks or signs of
wear and replace if necessary. Secure all caps and
filler plugs for all systems.
Always use a a flashlight or shielded trouble light
when checking for leaks – never use an open
flame. Never check for hydraulic leaks with your
hand. Hydraulic systems are under high pressure
and leaks in these systems can penetrate the skin
which can result in serious injury or even death.
Always use a piece of cardboard or wood when
looking for hydraulic leaks.
Be sure the trowel is
properly lubricated. See
that the fuel, lubricating oil,
coolant and hydraulic
reservoirs are filled to the
proper levels with the
correct fluids according to
the manufacturer’s
instructions and
recommendations.

PREPARE FOR SAFE OPERATION
Trowel.qxd 11/24/04 10:18 AM Page 8
FIRE PREVENTION
Always stop the engine and allow it to cool before
refueling.
Never refuel –
• When engine is running
• Near open flame or sparks
• While smoking
• In poorly ventilated areas
Never overfill fuel tanks or fluid reservoirs. In the
event of a fuel spill, do not attempt to start the
engine until the fuel residue has been completely
wiped up, and the area surrounding the engine is
dry. Replace fuel cap securely after refueling.
Inspect electrical wiring for damage or wear.
Batteries produce explosive gas. Keep open flame
or sparks away.
In case of accident or fire, be ready to act quickly,
yet calmly. Do not panic. Knowing ahead of time
where to locate a first aid kit, fire extinguisher, or to
get assistance will help should an emergency
situation come up.
CHECK THE WORK AREA
Learn – beforehand –
as much about your
working area as
possible.
Be observant of other
workers, bystanders
and other machinery
in the area. Keep all
unauthorized,
untrained people and
children out of the
area while the trowel
is in operation.

PREPARE FOR SAFE OPERATION
Trowel.qxd 11/24/04 10:18 AM Page 9
CHECK THE AREA
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.
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.
TRANSPORTING THE TROWEL
Never transport the trowel with float pans attached
unless safety catches are used and are specifically
cleared for such transport by the manufacturer.
Under no circumstances hoist the trowel more than
three feet off the ground with float pans attached.

weights recommended by the manufacturer. The
use of unauthorized weights could lead to
personal injury or damage to the trowel.
• Never fill the fuel tank while the engine is
running. Turn the engine off and allow it to cool
before refueling.
• The muffler, exhaust pipes and
other engine parts will become
hot during operation and will
remain hot for a while after
shutdown. Do not touch until
allowed to sufficiently cool. Do
not allow debris, rags, paper, or
leaves to accumulate around
these areas.
• Do not keep tools, buckets, loose materials on
the trowel while it is running and never allow
anyone other than the operator on or near the
trowel while it is in operation.
• Do not use the trowel for any purpose other than
its intended purposes or applications.

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.
• Keep all electrical cords away from rotating
elements, 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.

• Never hoist the trowel over areas where people
are standing or working.
• Remove tools and loose items before lifting.
• Make sure the crossbars on the safety catches
are in good condition if so equipped.
• Always consult your operator’s manual for the
best and proper lifting, loading, and unloading
methods.
WALK-BEHIND TROWELS
Some walk-behind trowels can be lifted or moved
by two people utilizing lifting tubes or other special
attachments. Generally however, they must be
lifted using lifting bales (special lifting brackets), or
other specific lifting points provided by the
manufacturer, and cranes, hoists, or forklifts. Be
certain any lifting devices used have adequate
capacity.
RIDE-ON TROWELS
Ride-on trowels are very heavy. They require
heavy-duty lifting devices such as cranes or heavyduty hoists to lift them on and off the concrete slab.
Be certain any lifting devices used have adequate
capacity. Some ride-on trowels are equipped with
lifting bosses that are used with specialized
apparatus to assist in moving the trowels around.
Use extreme care when lifting or moving a ride-on
trowel.

skin, eat holes in clothing, and
can cause blindness if splashed
into eyes. Always wear eye and
face protection.
Flush any contacted area with water immediately.
PERFORM MAINTENANCE SAFELY
18
Trowel.qxd 11/24/04 10:18 AM Page 18
FIRE PREVENTION
Avoid fire hazards.
Always stop the engine and allow it to cool before
you refuel the trowel. Do not refuel while smoking
or near open flame or sparks. Never overfill fuel
tanks or fluid reservoirs.
Remove all trash or debris. Make sure oily rags or
other flammable materials are not stored on or in
the trowel.
Check for fuel, oil, or hydraulic fluid leaks. Repair
the leaks and clean the machine before you
operate it.
Inspect electrical wiring or worn or frayed
insulation. Install new wiring if wires are damaged.
Do not weld or flame cut on pipes, tubes, or tanks
that contain flammable fluids or gases.
Ether and starting fluid is flammable. Do not smoke
when using. Always follow the instructions on the
can and in the manufacturer’s manual for your
trowel.
Always use a safe, nonflammable solvent when
you clean parts. Do not use flammable fluids or
fluids that give off harmful vapors.
Store all flammable fluids and materials away from
your work area.
Whenever the sparkplug is removed, do not test for
spark on gasoline powered engines if engine is
flooded or the smell of gasoline is present. A stray
spark could ignite fumes.
Know where fire extinguishers are kept – how they
operate – and for what type of fire they are
intended!
Check readiness of fire suppression systems and
fire detectors (is so equipped).
PERFORM MAINTENANCE SAFELY
19
Trowel.qxd 11/24/04 10:18 AM Page 19
EXHAUST FUMES
Engine exhaust fumes can
cause sickness or death.
When performing
maintenance, if it is
necessary to run an engine
in an enclosed area, remove
the exhaust fumes from the
area when an exhaust pipe extension. If you do not
have an exhaust pipe extension, make sure you
open the doors and get outside air into the area.
Ensure that permissible carbon monoxide levels
are monitored and not exceeded.
FLUID SIPHONING
Never siphon gasoline or hydraulic fluid using a
hose and suction by mouth. Ingestion of these
fluids even in small amounts will require immediate
medical attention and can cause death.
COOLING SYSTEM
Maintain the cooling system
according to the
manufacturer’s instructions.
Hot coolant can spray out
and you can be burned if you
improperly maintain or
service the cooling system.
Remove filler cap only when
cool.
PERFORM MAINTENANCE SAFELY

Trowel.qxd 11/24/04 10:18 AM Page 20
TROWEL BLADES AND PANS
• Do not attempt to clean, service or perform
adjustments on the trowel while it is running.
• Do not remove while the trowel is hanging
overhead. Always support the trowel securely on
a flat, level surface before changing blades or
pans.
• Always handle blades and pans carefully. Worn
blades or pans may develop sharp edges that
can cause serious cuts.
• Always replace worn or damaged parts with
service parts designated by the manufacturer.
• Replace blades and pans as a complete set –
even if only one blade or pan is showing wear or
damage. They can wear differently depending on
different jobs, and a difference in blade size will
damage the finish of the slab surface.
HYDRAULIC SYSTEMS
Hydraulic fluid systems operate under high
pressure. Even a small leak can have enough force
to penetrate the eyes or skin. If injury occurs, seek
immediate medical treatment by a physician
familiar with injuries that are caused by hydraulic oil
escaping under pressure.
Use a piece of wood or cardboard to find hydraulic
oil leaks. Do not use your bare hands.
Wear safety glasses to prevent injuries to the eyes.
