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.
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.
