Safety Information Walk-Behind Trowels
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 a gasoline
engine, a fuel tank, a gearbox, and a control handle. A set of four metal blades is
connected to the gearbox and is surrounded by a ring guard. The engine 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:
■Heat, noise, exhaust, and carbon monoxide from the engine
■Chemical burns from curing concrete
■Fire hazards from improper refueling techniques
■Fuel and its fumes, fuel spillage from improper lifting technique
■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.
