Topic tags/keywords: jet jtas-10xl maintenance motor

Bought a Jet JTAS-10XL off CG and while it’s in nice shape it was not cared for.

So while I’m cleaning it should I remove the motor case and blow it out or will compressed air just push dust into places it shouldn’t be?

I probably wouldn’t bother except for seeing reports like this: on this saw.

I would blow it out without hesitation using a relatively low pressure, say 60 PSI or so, with a fairly large nozzle. If it is a sealed case, that is not necessary, but the report makes it sound like the case leaks like a screen door on a submarine. If you do take it apart to clean it, consider how to tighten it up completely, perhaps with silicone, to prevent having to take it apart every year to clean it. Identify airways for cooling and be sure they are clear of debris.
I blow off my TEFC motors fairly often and have had no adverse effects.

Thank you Dan. Think I’ll enlist my pal who knows a lot more about motors when I do it as it sounds like the motor is unique to the manufacturer and I’d kick myself if I created a new problem. That’s one reason to buy a Unisaw: wide parts availability. That said, don’t think I’d find one for $600 in my area -and certainly not as in as good a shape as this one.

I’ll wait until I get the 220 line installed (hopefully in the next few days) and see how she runs first. There were some missing set screws in the arbor pulley. After I blow out the motor I then have to figure out where the table shim goes. The one that I didn’t note when I removed the table for transport during the purchase.

One problem at a time, right?

Appreciate your advice.

Maybe print out a copy for yourself and congrats on your new to you saw!

Blowing it out will likely help, but if it’s a crappy motor, the dust will likely do it in anyhow. Totally Enclosed Fan Cooled (TEFC) motors are expensive, but they are up to the job . . .
