or emit chemicals known to the State of California to cause cancer and birth

defects or other reproductive harm.

Laws

pertaining to

spark

arresters

NOTICE: State Health Safety Codes and Public Resources Codes specify that in

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.
