READ THIS MANUAL BEFORE OPERATING THE MACHINE
Most accidents in operation are due to non-observance of elementary safety rules and precautions.
Many accidents can be avoided if the causes are known and proper cautions are taken beforehand.
No matter how devices and protections are advanced, many cases prove that they cannot be as
effective as a careful and attentive behavior at avoiding accidents.
