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.
