2.Operation
2.1Application
This trowel is a modern, high production machine intended for floating
and finishing freshly poured concrete slabs. The machine’s good
balance, adjustable handle, and easily reached controls add to
operator comfort and productivity. An Operator Present Lever provides
added operator safety. Finishing rates will depend on operator skill and
job conditions.
DO NOT use this machine for any application other than troweling
concrete.
15
OperationCT 36-400E
2.2Installing Blades
See Graphic: wc_gr001097
There are four types of blades available for the trowels. Float pans are
large "pizza pan" style blades, which hook on over finish or
combination blades and are available for the 36" machines only. Float
blades are available for all machines and clip on over finish or
combination blades. Both are used in the earliest stages of work, and
are not pitched.
Finish blades are used in the final stages of working, and are
progressively pitched to burnish the concrete.
Combination blades can be used throughout the concrete working
process. They are used in place of float blades or pans and finish
blades.
Note: Trowel blades must NOT be interchanged, i.e., do NOT put
larger diameter blades on a smaller diameter trowel.
2.2.1Finish blades are flat on both edges and can be installed in either
direction.
When installing combination blades, orient blades as shown (a). This
positions the raised edges of the blade correctly for the clockwise
rotation of the machine.
2.2.2Secure blades to trowel arms with screws (b). Dip threads of screws in
grease prior to installation. This will prevent concrete from cementing
the screws in place and will make removal of the blades easier later on.
2.2.3Plug the remaining threaded holes in the blade brace with plastic plugs
(c) to prevent them from filling with concrete.
Do not lift the trowel overhead with a float pan attached, as the pan
could fall off and strike personnel working in the vicinity.

2.6Extension Cords
When choosing an extension cord, make sure it has adequate wire
size for safety. An undersized cord will cause a drop in line voltage
resulting in a loss of power and overheating. The table below shows
the correct wire size to use depending on cord length. If in doubt, use
the next heavier cord size. On motors being used outdoors, use
extension cords rated for outdoor use.
Improper use of extension cords can cause overheating and create
serious fire or shock hazards. NEVER use worn or damaged cords!

Trowel.qxd 11/24/04 10:18 AM Page 6
LEARN TO BE SAFE
• Read the operator’s
manual. If one has not
been provided, get one and
study it before operating
the equipment.
• Learn the location and
understand the functions of
all controls before
attempting to operate the
equipment.
• Know the meaning of all identification symbols on
the controls and gauges.
• Check to determine that the manufacturer’s
furnished safety warning labels are securely
attached to the trowel and all warnings can
clearly read. Replace labels and decals if they
are missing or become worn or unreadable.
• Know the location and type of emergency shutdown control the trowel is equipped with.
• Never start or operate the trowel without
protective guards and panels in place.
• Know the capabilities and limitations of the
trowel.

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.
Always consult the manufacturer’s operation
manual for specific information on transporting the
trowel.

START CORRECTLY – START SAFELY
Before starting, check for proper functioning of all
operation and shutdown controls. Check all
controls to be sure they are in the correct startup
position. Know the proper starting procedure for
your trowel. Follow the manufacturer’s operational
instructions.
WALK-BEHIND TROWELS
• Ensure that the operator is familiar with the
trowel and is trained on its operation.
• Ensure the operator is well rested, not fatigued,
is alert, and not impaired in any way
(medications, drugs, alcohol, etc.).
• 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.
• You are ready to operate the trowel!

SAFE WORKING PROCEDURES
DANGER – CARBON MONOXIDE
Exhaust from the engine contains
poisonous carbon monoxide gas
that is not easily detected as it is
colorless and odorless. Exposure
to carbon monoxide can cause
loss of consciousness and may
lead to death! Do not operate
your trowel indoors or in an enclosed area unless
adequate ventilation is provided. Ensure that
permissible carbon monoxide levels are monitored
and not exceeded.
OTHER PRECAUTIONS
• Never leave the trowel unattended while it is
running.
• Always keep clear of rotating or moving parts.
• Never use additional weights other than the
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.

WORK SAFELY
Trowel.qxd 11/24/04 10:18 AM Page 13
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.

PRECAUTIONS
• Power trowels are heavy and awkward to move
around.
• Do not attempt to lift the ride-on trowel by the
guard rings.
• Use proper heavy lifting procedures.
• Keep all non-essential personnel clear of the
area.
• 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.
STORAGE
Always store equipment properly when it is not
being used. Equipment should be stored in a clean,
dry location out of reach of children.

SERVICE AND MAINTENANCE SAFETY
Poorly maintained equipment
can become a safety hazard! In
order for your trowel to operate
safely and properly over a long
period of time, periodic
maintenance and occasional
repairs are necessary.
Do not attempt to clean,
service, or perform adjustments
on the trowel while it is running.
GOOD
HOUSEKEEPING
Keep area clean
and dry if possible.
Oily and wet
surfaces are
slippery; greasy
rags are a fire
hazard; wet spots
are dangerous
around electrical
equipment.
GENERAL PROCEDURES
Do not perform any work on the trowel unless you
are authorized to do so.

parts and cause serious injury.
Keep hands – and clothing – away from moving
parts.
GUARDS AND SAFETY DEVICES
After performing maintenance make certain all
guards and panels have been reinstalled and all
safety devices are functional.
BATTERY MAINTENANCE
Always wear eye and face
protection.
Batteries produce explosive gases.
Keep open flame or sparks away.
See the manufacturer’s instructions
when servicing the batteries, when
using jumper cables, or when using
a battery charger.
Use a flashlight to check battery
electrolyte level. Always check
with engine stopped.
Battery electrolyte is poisonous.
It is strong enough to burn your
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
20
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.
