Recent purchase of MB15 trying check all functions. At this point I'm trying to MDI data ( not sure if the format is correct but no syntax error) but when I hit cycle start an alarm pops 119 Chuck open 1 and its closed. I'm not seeing fluid in the site gage but I feel the filter line moving fluid Anybody have an idea why when I input data in MDI and try to cycle start an alarm pops 119 chuck open or what to check. I have limited info or manuals on this machine so any help would be greatly appreciated.
