I need to get a once over and cleaning for my "new" machine (no, Billy, despite your excellent tutorial, I wouldn't dream of attempting that myself!). But I know this is exactly the wrong time of the year to expect fast service (heck! ANY service!). However, I'm hesistant to use the machine for more than a few minutes without oiling it -- but without the manual I'm not sure WHERE to put the oil. Any suggestions? Thanks!
