Hello,
what kind of oil should be lubricated with? I mean the warning on your instructions ("fill throat packing nut with lubricating oil 3-5 drops")! Which oil is this and I would like the SAE mark so I can lubricate correctly.
And one more question, namely, is it necessary to lubricate something else and with what kind of oil? I would be very happy with your answer, only this way I will work more easily and correctly with your machine :)
