95 year old hobart mixer: two pole single throw switch
The knife switch looks like it has a spring which is broke. the spring would encourage the blades to move at fast speed to minimize arcing when thorwn. the mixer itself is said to be 95 years old and it could be wired for 110 volts but it also has enough wires in the switch box to possibly be three phase. the switch was wired for 220 volt and i need to find a replacement part for two pole on/off

Not sure if you are asking if an H600 is automatically a single phase or a 3 phase and the answer is NO. Depending on the motor it will be 1 phase or 3 phase application. It will have 4 wires versus 3 wires -- hope that makes sense 3 of the wires are "HOT" on a 3 phase and only 2 are "HOT" on a single phase Motor.
usually 2 wires that AC current goes through. check with volt meter set to ohms test for resistance . if you know the value .of resistance ? but if the machine has power but does not run . you know there is a thermal fuse hidden .once blown it does not reset..so you can throw it away. please don't..just replace the fuse or get a resettable one Radio shack or local electronic store . it is a size of a ADVIL pill with 2 wires inline of power coming in to switch ... >^.^<
The start switch should be a single pole momentary switch which engages a latching circuit. When you press the stop button it opens the latching circuit. The latching circuit is usually a relay, but it could be a centrifugal switch on the motor. I can't find a wiring diagram to be able to tell you for certain.
Check the spring pin that locks the motor shaft to the main drive gear in the gear box. You should be able to turn the motor from the back at the cooling fins and watch the shaft spin in the gear, that is if the pin is sheared. That is a common problem. if you plan on keeping this machine for a while, i recomend that you spend a little more on a quality spring pin,
no there are no adjustments . you must have bent the case just a little , i dont see any good news for you , sorry . i have worked on hobart mixers for years and you should get 5-10 years out of that gear
