Magnetic switch expertise needed !
I was given a 1987 Grizzly 1021 15 ” planer by a family friend. He had purchased it in 1987 but as it required some extensive rewiring in his 100 year old house it was never run since leaving the factory until the other day. It runs for 3-5 minutes and then the magnetic switch trips (sometimes it makes a fairly loud sound when it does). It takes a minute or two to get to where the stop (reset button)allows it to restart but it cuts out again soon. The motor does not feel any hotter than my jointers does after the same time span. I opened the switch cover and noticed that it appeared that it was possible to adjust the switch. Of course this should have been done at the factory but I am wondering if it could be the problem. What really leads me to think that is that there is dial that has markings on it from 3 o’clock to nine o’clock. At three o’clock is just a line (-), next (clockwise) a 10, then two more lines, then a 12 (at the 6 o’clock position) then 2 more lines, then a 14 and finally a line at 9 o’clock. The indicator is pointing at the line just before the 12. On the outside of the switch is a plate stating that the switch is rated for 220 volts, 12 amps. The motor plate states the same. Perhaps you can see what I am getting at :should the indicator point to 12 instead of the (11?) it is pointing at now ? Lastly I will add that there is also a sliding switch that has the letter H on the left and the letter A on the right and the sliding swtch is all the way over at the H.
Thanks to any who can advise me!
