The schematic indicates a 3 phase 7.5 motor but other pictures show a 3
hpase 5 hp motor hanging on the saw.
Having been used in a school the 3 hpase would sound right.

Hadn't noticed anything about saw's previous use only that schematics
showed the model was manufactured as 3PH--and that since most
individuals don't have 3PH power handy made me wonder about whether
somebody could have swapped out the OEM motor for something else which
doesn't have correct geometry before the OP got it...

Maybe the 5/7.5 hp is the Type 1/Type 2 difference I saw noted on
schematics earlier???
