Page 28: Air Quality
5.3.1 Lubrication The MN4KB2 Series solenoid valve systems use pre-lubricated valves that usually do not require lubrication from the outside. If you have to lubricate a valve, use Type 1 turbine oil (ISO-VG32) without additives. Excessive lubrication and extremely low pressure may cause a longer re- sponse time. - Page 29 ５ OPERATION 5.3.4 Foreign matter in the compressed air 1) Supply clean compressed air that does not include oxidized oil, tar, carbon, or other foreign matter from the air compressor. (1) If oxidized oil, tar, carbon, or the like enters a pneumatic device and sticks to its components, an increase in the resistance at sliding portions may cause a malfunction.
