Manaul for Hitaxhi EX 50-URG

Anybody have a manual for a Gray Market Hitachi EX 50 URG. Its a 1992ish model. I have a Parts Book (not alot of help) for this machine but would really like to get a Operators manual or any other books available. I also have the manual for the 3 banger Isuzu engine. New, Used or Photo Copied would be a big help.

Next dumb question is:
What does the URG mean?

Regards
Charlie S
