Texting from the UK - any idea where I can get some mineral oil for our Berkeley gravity feed slicer?

The Problem most likely is that remnants or build up is inside the shaft of the slide that the arm rides on, under the slicer you will see a rod that it rides on, most of the time it gets dirty and build up occurs, I may get some back lash but I unplug machine, lift up, heat up the rod and the part that rides on it with a blow torch and that melts all the junk away carefully not to burn yourself i slide it up, then remove remnants with steel wool (hot) then repeat and clean rod until moving free, then oil both with mineral oil. and if you see some one using veggie oil or pam on it beat them with a stick across the knuckles firmly until they understand, repeat if necessary. lol
Good luck

under slicer is a rod arm slides on, heat it with a torch melt all the junk away from using vegetable oil clean rod with steel wool, never use veggie oil,use mineral oil

Vegtable oil is safest!!!

I would get it rebuilt, most or all electric motor places will do it

most times the belt fill slip if you overload it and no they don't have oil holes

You have to put mineral oil on the bar that the arm slides on otherwise it gets full of junk and stiffens up

Old enough to know that you unplug it before you work on the blade!

This is the deal jason,get a rubber mallet,mineral oil and a mapp torch.If you look at the guage plate this is the part that the meat/cheese goes on you will see 2 rods that connect it.Heat the rods up and put on mineral oil.Hit the guage plate down while turning the knob left then hit it up and knob to the right ,keep doing this and apply plenty of oil .It will be good as new!
