Low Oil Pressure/Generator/Interstate

I'm sure I'm using this site incorrectly because my problem can't be uncommon.
Been trying to turn on the generator. It starts, stays on a few seconds, and stops.
Two red flashes mean low oil pressure.
I can't find my book....of course....have googled for help and failed. Looked here and failed.
Is low oil pressure something I can fix? Is it simple? Can anyone help or tell me what to google?
Appreciate any/all help.

What kind of generator do you have.

Obviously, you've checked the oil, sorry.
It could be a bad oil pressure sensor or major engine trouble.
May be best to let the experts look at it.

From what I could glean from your post, the generator is a propane fueled 2.5 KW Onan unit in a Hush pack.
There is a low oil switch located in the oil pan.

Here's the manual:
This would be beyond my ability, but you may be a hands on guy.

Thanks for the replies....I'm sorry I haven't responded sooner. I didn't get an email that I had received any responses and assumed I hadn't. Never assume! I Finally found the manual. It was exactly where I left it...argh. I have a Cummins Generator. No, I'm not a "hands on guy"....however, I am trying to be a hands on gal. Ha! And, no, I didn't check the oil. Didn't know how and frankly a bit leary of crawling underneath to check it. I finally found a local guy who is going to check it for me. Hopefully it's simply low on oil and adding more will correct the problem. It only has 83 hours on it usual for the oil to get low so quickly? Perhaps it isn't quick. At any rate, I'm praying my several attempts to turn it on hasn't harmed the unit. Time will tell. Thank you so much! Oh! Cummins and Onan is the same...right?
