My 4th-Axis Leaks Oil like a Sieve

I filled it up with oil the very first time I used it just like the instructions said to do. I've had it for over a year now so the warranty has now expired.

I've used it a total of five times since I bought it; yesterday being the fifth time. When I checked the oil level it was bone-dry so I proceeded to fill it to the correct level. With the rotary table standing vertically I squirted some fresh oil into the fill-hole. I notice that the the little sight-glass showed no change after squirting several ounces of oil into it.

DUH! The oil was running out from underneath the rotary table just as fast as I was pouring it in.

I haven't tried to do anything about it yet. My work schedule is busy right now so I've had to set it aside until I can devote my complete attention to it. I thought I'd mention it here in hopes that one of you guys has had a similar experience; and maybe you can suggest the quickest way to fix it.

I'm looking for wisdom without the sarcasm if possible. I'll figure it out eventually but rather than the trial and error approach, I thought that maybe someone who's been there and done that could chime in.

Thanks in advance.
