General maintenance- To ensure correct operation and prolong service life, it is recommended to clean the piston rods whenev-er possible.- It is advisable to keep the friction rule lubricated along which the upper roller support slides. It is also nec-essary to ensure a minimum lubrication of the inner walls along which the upper roller support slides.- Regularly check the oil level in the hydraulic tank at the bottom of the machine. To obtain a correct readingof the oil level the lower rollers should be in their lower position.In order to lubricate the moving parts of the machine that require lubrication, it’s recommended to follow thenext instructions:- Clean the surface to be lubricated with a cotton cloth or a soft rag that does not release any threads. Toremove the accumulated grease and any possible residues that have become stuck to it.- After cleaning, reapply grease onto the surface with the help of a rag or a spatula.- Spread the grease evenly without creating excesses or clumps.- Once the machine is lubricated, using the mobile control that manages the height of the upper roller, raisethis until it reaches its highest point.- When the upper roller comes to a stop, reverse the direction of the piston to lower the roller down to itslowest point.- Repeat the operation to ensure that the friction rule is lubricated.- Repetir la operación para asegurar el engrase de las regla de fricción.- Lubricate the machine regularly, according to use.* It is recommended to use lithium grease for the rollers N.850 EP-2.To replace the hydraulic oil, the following is recommended:- Check the oil level in the tank every 500 hours of use.- The oil cap is located at the top of the tank. If it is necessary to add oil, fill to the level of the sight glassat the front of the tank.- Change the hydraulic oil in the tank every 2000 hours of work or every 5 years.- Remove the old oil in a tray and dispose of it at the nearest recycling point.- Fill the tank with new hydraulic oil to the level of the sight glass located at the front. The capacity of thetank is approximately 13 litres.- Return the hydraulic assembly to its location and secure it to the machine with thebolts.* We recommend the use of CEPSA HIDRÁULICO HM 68 hydraulic oil.
