Refer to the revised software for the 2 previous machine. In Re: amendments to the previously mentioned We want to know to progress, and the issue that we have now is detected. When the working hours worked to 4000 hours find in enclosure. We find that customers ignore to allow to do for the maintenance, as it may affect the performance of our compressor. We think there are probably ways to work around this issue, reminding customers that the maintenance period and to maintenance the machine by us only. From our past experience when the working hours due to maintenance period is pop up warning up that term maintenance and please call authorized service center of the machine to machine maintenance.
