Ex1050 lube pressure setting error cnc dugard lathe 26120 fanuc

Hey guys I've an issue with the lubrication on my cnc lathe, every so often it comes up with a message saying ex1050 pressure setting error, it goes away when I reset machine. The pressure gauge only goes up to 7kg/cm2 when I press the button, lube oil seem to be coming out between carriage onto the rails. Thanks any advise will be greatly appreciated.

Possibly the pressure switch has failed or requires adjustment

Where abouts is the pressure switch, thanks

On top of pump I think depends on model of lube pump
Send me a pic of pump either on here or preferably by PM as I don't get notifications for this post
