3 GENERAL INFORMATION PURPOSE OF THE MANUAL This manual was designed by the manufacturer to provide authorised technicians with the information required to perform repair, replacement and extraordinary maintenance operations. All information regarding the machine that is not contained in this manual can be found in the supplied instruction manual. In addition to adopting good use techniques, the recipients must carefully read and strictly apply this information. This information has been produced by the manufacturer in his own original language (Italian) and can be translated into other languages to satisfy legal and/or commercial requirements. Time dedicated to reading this information will avoid personal safety and health risks and economic damages. To facilitate consulting, the manual has been divided into several pamphlets with chapters and sub-chapters making each subject independent while still following the operative logic. The descriptive contents found at the beginning of the manual help to easily find the subjects you are interested in. The manufacturer reserves the right to carry out modifications without obligation of prior notice. To better stress the importance of some passages or to indicate important specifics, symbols, whose meanings are described as follows, have been adopted. Danger Attention Indicates critically dangerous situations that, if neglected, can result in serious personal safety and health hazards. Warning - Caution Indicates that suitable actions must be employed in order to avoid personal safety, health hazards and economic damages. Important Indicates particularly important technical information that should not be neglected SAFETY INFORMATION Different danger situations that, in particular conditions, may result in personal safety and health hazards existing in the workplace. In order to limit these situations, some suggestions are provided below: Wear the indicated personal safety protections. Perform operations according to the indications provided by the manufacturer. Do not litter the environment with pollutant material; perform disposal according to the pertinent laws in force. Before performing any type of operation on the machine, disconnect the batteries and, if necessary, remove the blade

4 Before performing operations on the perimeter cable line or on the electric system connected to the recharging base, turn the machine off. Generally clean the machine and be careful not to wet or damage electrical or electronic parts. Always use the anti-static bracelet when working on the electronic boards to avoid their irreparable damage. Batteries and their support make up a single, inseparable unit: to avoid damages and risks to the operator, do not attempt to separate them. Always replace parts with original spare parts. This may assure machine functionality and the foreseen safety level TROUBLE SHOOTING This chapter lists all foreseeable machine problems with possible causes and potential solutions.
