Cleaning a Keystoker ?

I know this question has been asked before but I can't find it. I'm wondering what kind of oil I should use to lube all the moving parts. Yes, I know I was supposed to clean this back in May, I was a very bad boy and I am sorry, lol.
But, as you all know, nice weather hits and all hell breaks loose, summer is here lets get everything done. The poor keystoker sits in the corner forgotten. So please don't yell at me to loud. I know I have done wrong and I should be punished. I will be cleaning the keystoker later today. Anyway, thank you for your input in advance.

I usually use a good 3in1 Oil for motors. There should be some oil holes on the bearing housing. If you have a direct vent, you may want to pull it a part and vacuum the impellers, etc...

Hopefully none of your mechanisms are not frozen, that's why it better to clean it out after the burn season and lube everything up. The coal ash and moisture (humidity) will corrode everything if not cleaned up.
