question on a little gian external pump

[phatphisher]

does anyone have the original owners manual for a little giant 3-mdqx-3 (or similar) in-line pump? i have't used it for over a year. pump label says to oil it every 6 months with SAE 20. purchased the oil but hav no idea how and where to oil it. tried looking in little giant's site and no help there to be found.

any advise is appriciated. thanx.

When I had my LG pump, there was a little whole towards the back that said oil. I never oiled mine though.
