I got a HL600 Hobart dough mixer where the transmission sounds like it's grinding or something, only when it goes to the 3rd speed and 4th speed.
The manual says to contact my local hobart service office for the proper transmission oil, what is the proper oil? Can I just use some 10/50 motorcycle oil?
Any idea's as to why it's making noise, please do tell. I just pulled the top off the transmission so I'll be looking.
