Nitrogen can be used to purge the entire system including the compressor, but you MUST use a vacuum pump to get all traces of nitrogen, and any other non-condensable gasses out of the system.
Air or nitrogen in the system will cause excessive head pressure like you describe.
You also have to be careful you don't use too much silphos or solder on your discharge connection on small compressors, because the excess molten material can flow down and block the discharge port.
It's only a shock if your not expecting it!
