8 Types of AB Service maintenance Maintenance PREVENTIVE MAINTENANCE (ROUTINE, EXTRAORDINARY) CORRECTIVE MAINTENANCE CYCLIC MAINTENANCE PREDICTIVE MAINTENANCE DEFERRED MAINTENANCE URGENT MAINTENANCE Maintenance planning includes two areas of operation: 1 Preventive Maintenance: carried out at predetermined intervals or based on prescribed criteria aimed at reducing the probability of malfunctioning or deterioration of plant operation. 1.A Cyclic Preventive Maintenance: carried out based on preset time intervals or utilisation cycles but without prior inspection of the plant conditions. 1.A.1. Routine preventive maintenance: carried out according to the maintenance calendar (e.g. oil and filter change, valves adjustment). 1.A.2. Extraordinary preventive maintenance: carried out according to the maintenance calendar with an interval of about 10,000 hours, where the most important maintenance is carried out after 30,000 hours of operation and is defined as Minor Overhaul. 1.B Predictive Preventive Maintenance: carried out following a prognosis deriving from analysis and subsequent assessment of the significant operating parameters. It allows improving and optimising the maintenance calendar. 2 Corrective Maintenance (unforeseeable extraordinary maintenance): carried out following detection of unforeseeable malfunctions and aimed at restoring proper plant operation. 2.A Deferred Corrective Maintenance: not carried out immediately after a failure has been detected, but deferred to the next preventive maintenance. 2.B Urgent Corrective Maintenance: carried out without delay after a malfunction has been detected in order to prevent more serious consequences. 8

10 The Service for small LINEA ROSSA plants up to 125 kw. PLANTS FUELLED BY BIOGAS PRODUCED FROM ANIMAL WASTES, BY-PRODUCTS OF ORGANIC ORIGIN AND DEDICATED CROPS. EFFICIENT AND EASY TO MANAGE The new small compact modules of the LINEA ROSSA line (63 to 125 kw) are designed to make assistance and maintenance jobs easier, so the customer is better able to manage and control them by itself. Servicing the modules is particularly simple, thanks to a total accessibility to the engine compartment and all the component parts. The acknowledged and tested reliability which distinguishes AB cogeneration units is also to be found in the LINEA ROSSA modules - plants which ensure maximum energy efficiency, especially as regards the production and use of thermal energy. AB dedicates a special assisted maintenance program to these plants, with a convenient formula, which does not require advanced expenditure and integrates the routine maintenance work done by the customer, so the module is always in perfect operating condition, backed by all the experience and expertise of the AB service. 10
