Atlas Copco is a worldwide manufacturer of drilling, haulage, concrete equipment, compaction devices, air tools and motors, and yes, the Atlas Copco compressors.
Their air compressor lines include centrifugal compressors, high pressure compressors, reciprocating and rotary screw in lubed and non-lubricated design, and a broad range of tow-behind portable air compressors.
They have been around a while! The Atlas Copco we know today was founded in 1873. Their origins are, I believe, in Stockholm Sweden.

I have a 2012 Atlas Copco XAS 850 JD7 air compressor. On the control panel comes up Service Timer 1. Fluids are changed, nothing looks out of the ordinary. The engines runs and functions fine but the fault code litters the screen to be able to see fuel percentage and shut down time. Is there a way to reset this off the screen or something to be done to get rid of?
Thanks in advance

All the different valves And lines have been taken apart, cleaned, unloader verified, regulating valve checked, fluid and filters changed.
