1 Operating & Maintenance Manual s are utilised to remove contaminant from hydraulic systems. Long working life of the hydraulic components and correct use of the hydraulic systems can be assured only when maintenance is performed correctly and at regular intervals. It is essential to use indicators that serve to inform the user of the need to change the cartridge. ffective contamination control can be assured only by the correct use of clogging indicator. 0

2 INSTLLTION heck that the pressure value of the selected filter is higher than the system s maximum operating pressure (the maximum pressure value is shown on the dataplate). heck that the filter body contains the filter cartridge. heck that the operating fluid is compatible with the material of the body, cartridge, and seals. Install the filter in an accessible position for correct and troublefree maintenance and visibility. Start the machine and check for the absence of oil leaks from the filter and relative fittings. F Repeat the visual inspection when the system arrives at the operating temperature of the oil. MINTNN ll maintenance operations must be performed only by suitably trained personnel. The hydraulic system must be depressurised before performing maintenance operations. Maintenance must be carried out using suitable tools and containers to collect the fluid contained in the filter body. Spent fluids must be disposed of in compliance with statutory legislation. o not use naked flames during maintenance operations. Use the utmost caution in relation to the temperature of the fluid. High temperatures can lead to residual pressure with resulting undesirable movements of mechanical parts. HNGING TH FILTR LMNT The date on which the filter elements are changed must be entered in the machine datasheet. Spare parts installed must be in compliance with the specifications given in the machine operating and maintenance manual. bodies and tools must be thoroughly cleaned prior to each maintenance operation. fter having opened the filter to change the filter element, check the condition of the seals and renew them if necessary. lean thoroughly before reassembling.
