Pneumatic underpinner

[Nicole]

With a pneumatic underpinner should the pressure be released at the end of the day's work, week just for the weekend and holidays? I don't know as my underpinner was secondhand and came without instructions. I don't want to do the wrong thing and incur costs in getting it fixed. What does everyone else out there do?

I switch my compressor off and close the tap on the tank at night, any air in my machines usually leaks out. You should drain the tank of your compressor every week as well, to keep moisture out of the tank, this is very important.
