Here is a pic of a similar tank to mine. The 'inidicator' knob is at the far left. Its not the oil tank cap as I have been using that for filling. Its the other one with an 'arrow' indicator on it. I guess from your post, this must be the oil filter cleaing indicator. How does it work? Is it just set manually or does it move gradually as the oil filter gets dirty? I have no graphics on my tank (someone painted!) anymore so its hard to tell where the indicator is supposed to be pointing.
Many thanks for the posts.
