1.2 Machine Description and Intended Use
This machine is a concrete floor saw. The Wacker Neuson Floor Saw consists of a
gasoline engine, a fuel tank, an operator’s console, and a diamond-tipped circular
blade protected by a safety guard. The gasoline engine supplies power to the
blade through a belt- or direct-drive transmission. The operator walks behind the
saw, guiding the rotating blade through the cut. From the console, the operator
controls engine speed, cutting depth, and power transmission.
This machine is intended to be used for cutting decorative grooves and control
joints in concrete slabs.
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 for cutting loose materials, such as bricks or tiles
Using your hands to guide materials to be cut into the saw
Using the machine to carry or transport passengers or equipment
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
Fire hazards from improper refueling techniques
Fuel and its fumes
Personal injury from improper lifting techniques or operating techniques
Cutting hazards from blade segments or spinning blade if operating the machine
incorrectly or inattentively, or from an exposed blade during transportation
Dust and vibration
To protect yourself and others, make sure you thoroughly read and understand the
safety information presented in this manual before operating the machine.

replacement parts or those parts equivalent to the original in all types of
specifications, such as physical dimensions, type, strength, and material.
Lifting and
transporting
When lifting the machine:
Make sure slings, chains, hooks, ramps, jacks, and other types of lifting devices are
attached securely and have enough weight-bearing capacity to lift or hold the
machine safely. See chapter Technical Data.
Remain aware of the location of other people when lifting the machine.
Make sure the transporting vehicle has sufficient load capacity and platform size to
safely transport the machine. See chapter Technical Data.
To reduce the possibility of injury:
Do not stand under the machine while it is being lifted or moved.
Do not get onto the machine while it is being lifted or moved.
ALWAYS support the machine securely before changing blades.
