Yes, because they are simple machines. Those with V-belt drives need the drive system checked and adjusted once a year. Otherwise, you need to check and clean the cooling pads regularly, depending on the level of pollution in the environment – at least every 6 months. In clean locations, once a year is enough. Clean cooling pads mean the highest cooling performance and that is what you want. Check the water tank (reservoir) once a year and clean out if necessary. Follow the Owner’s Guide book.
