Do not use the machine without guards and do not start the engine when the engine hood is open, unless this is expressly prescribed for some specific maintenance operations. 2 Many accidents are caused by insufficient knowledge of and failure to comply with the safety regulations pre- scribed for the maintenance operations that must be performed on the machine.
In order to avoid accidents, before starting work and before carrying out any maintenance operation, carefully read and be sure to understand all the information and warnings contained in this manual and given on the plates ap- plied on to the machine. To identify the messages regarding safety that are included in this manual and written on the machine plates, the following words have been used. DANGER • This word is used in the safety warnings in the manual and on the plates when the situation is dangerous and it may possibly result in serious injuries or even death. These warning messages and plates describe the safety precautions to be taken in order to avoid any risk.
Non-compliance with these instructions may also re- sult in serious damage to the machine. CAUTION • This word is used in the safety warnings in the manual and on the plates to signal risks that may cause moderate damage or injuries. This kind of message can be used even to indicate the risk of damage to the ma- chine only.
