I recently purchased a repo unit with less than 300 hrs. I have most bugs worked out but wanted to know if the heat is overkill on the low setting? This unit will heat up to over 240 in a few mins. On the low setting, is this proper operation or is the thermostat bad? Also the vacuum regulator on the top of the machine rattles a ton and the vac gauge only reads slightly over 10 hg. What is safe operating vacuum pressure and how do you adjust the thing?
