If the on/off is on the back then that just means you have a pre-2004 viking, as for lubing it up, put a couple of drops in the air fitting, shoot 10-20 times (take your barrel off to stop oil from building up in it), then put a drop or two behind the ram, its better to put too much then too little, its impossible to ruin your vike with extreme lube unless you put it directly on the board. Then have fun, vikings are incredible guns, too bad I think the annodizer lost mine.
