Oil Inserter

[crhfish]

I hope this is the correct place to ask this question. I just recently purchased some oilers and with them came an oil inserter. I have never used one and cannot find anything on the net that explains how you would use one. It looks like it might be used to oil shock jewel systems without having to remove the jewels.

It's a neat looking little device. Can some of the experts point out a location on the web that would explain the proper use of one of these.

Thanks in advance.
