1.2 Machine Description and Intended Use
This machine is a walk-behind concrete finishing trowel. The Wacker Neuson
Walk-Behind Trowel consists of a frame onto which are mounted an electric motor,
a gearbox, and a control handle with a terminal box. A set of four metal blades is
connected to the gearbox and is surrounded by a ring guard. The motor rotates the
blades through the gearbox and clutch mechanism. The rotating blades ride on the
surface of curing concrete, creating a smooth finish. The operator walks behind the
machine and uses the handle 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:
Chemical burns from the curing concrete
Heat from the electric motor
Electric shock and arc flash
Personal injury from improper lifting techniques or operating 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.

1.4 Operator Safety while Using Electical Equipment
NEVER operate machine with damaged or worn electrical cord! When using an
extension cord be sure to use one heavy enough to carry the current load.
Prevent body contact with grounded surfaces such as pipes, metal railings,
radiators and metal ductwork.
DO NOT operate electrical devices in rain or snow. Keep motor, switch and
electrical cords dry.
DO NOT use machine in wet locations.
Do not plug in the trowel with the motor cover, switch box, or terminal box cover
removed.
When motor is used outdoors, use only extension cords intended for and
marked for outdoor use.
Use only appropriate extension cords that have grounding-type plugs and
receptacles that accept the machine's plug.
ALWAYS keep all electrical cords away from heat, oil and sharp edges which
can damage them. Inspect all electrical cords before each use and have
damaged cords replaced or repaired at an authorized service center.
To reduce the risk of electric shock, all equipment must be properly grounded.
Connect this trowel to grounded receptacles and extension cords only. Make
sure power supply has either an Earth Leakage Circuit Breaker (ELCB) or an
isolation monitor in the circuit.
NEVER allow children or people other than the operator to handle power cable
and extension cords.
NEVER operate trowel in areas exposed to flammable or explosive liquids or
gases! The motor brushes spark during operating and could ignite fumes.
NEVER operate machine if switch does not function properly. Have defective
switches replaced by an authorized service center.
NEVER yank cord to disconnect it from receptacle.
NEVER allow trowel blades to cut or become entangled in the power cord.
ALWAYS make sure motor switch is in “STOP” position before plugging trowel to
power supply.
ALWAYS check the power supply before running the trowel. Using the wrong
voltage supply will damage the motor.
DANGER
Electrical motors present special hazards during operation! Failure to follow the
safety guidelines described below could result in severe injury or death.
