How do i adjust a jet bandsaw jwbs-9 blade tension


You should check your manual. There's a blade tension handle on my bandsaw, which is adjusted every time I need to change tension or change blade. There ways how to check the correct tension, you can pluck the blade like a string on a guitar and if you hear music not like sound, tension is good. Or you can follow the suggestion blade tension on your saw. or you may also use tension gauge.

Replace guide bearings on jwbs-18 saw


" That one will be a press fit onto that eccentric shaft. Small bearings like that are easy to drive off with a suitable punch or mandrel. Simply stand it up in the jaws of a vise so the jaw edges contact the outer rim of the bearing and use a hammer to drive it out. Put a washer or similar bit of metal between the shaft end and the punch to protect the face."
Make sure before you put the new bearing on that the shaft is clean and smooth.

Tire comes off wheel


Are you using new tires? Urethane or rubber? Make sure the adjustment are correct or probably you need to replace the
tires. I am using ulta blue urethane tires because it lasts longer and it doesn't need gluing. Urethanes are more durable
than rubber. I got mine on http://bandsawparts.com/ultra_blue_urethane_tires.cfm .

I cannot get the blade to track correctly on my JET 12" band saw. What could be wrong? I have done exactly what the manual says to do. I am not sure the square box on the outside is fitting. The little arm...


i love bandsaws, they are one of best and most universal woodworking machines, used as well in food and metal industries.

now, what you should know about bandsaw that it have several points of regulations and all of them must be adjusted correctly. basic "anatomy" of bandsaw is that it have body, in it there is driving wheel (bottom) and tension wheel (top), both of these are protected by rubber "tyre" usually crowned, that allow for bette adjustment and protect teeth on the band.

start with tension, open covers, retract top (above the table) and bottom (below the table) guides so blade is not touching the rear bearing or side slides.

1. rotate top wheel and see where blade is wandering, regulate tension and tilt on the wheel till band position itself on the centre of the top wheel and cuttin edge is off the wheel or rubber and do not touch the wheel or raiser.
2. cut strip of paper and slide top guide towards the blade till bearing touch blade through the paper (paper thickness is about correct distance of bearing to the blade), allowing paper to be slided out without tension. lock it in.
3. insert paper on internal side of the blade and slide internal slide guide block till you can only pull the paper out, lock the slider.
4. repeat previous operation on external guide block and after you slide paper out, lock it in position.
5. manually rotate the tension wheel, should operate freely, without wandering
6. repeat step 2 to 5 on the bottom guide
7. close the covers
8. adjust hight of the guide suitable to cut , allowing about 2 finger breaths above the cut piece.
9. switch on the bandsaw and switch off, after it stop, check for tension, switch on and make test cut.

this general rule applies to all bandsaw, regardless of brand, make, vintage. do remember that this is not a toy, it will cut through, wood, metal and your fingers...

do remember, that these operations must be performed every time when you change the blade, to not forget to use bit of silicone or teflon spray if you cut very sappy or green wood, do not press and force, use protection screen and googles, you have only two eyes and there are no spares...

Top wheel part broke off


I suspect the part you need is 150086 "Upper Wheel Shaft". You can confirm this by checking the exploded diagram for your bandsaw which can be downloaded at http://content.wmhtoolgroup.com/manuals/708115K_man.pdf.

See page 25 for exploded diagram showing wheel shafts, bearings, etc..

It might be worth checking with JET about warranty since I believe that band saw has a 5 year warranty. You can check here for a service center near you.

Is blade being guided? Use a straight edge to guide the material being cut.

Tire keeps rolling off


I'd say you have the wrong size tires, or at least defective or poor quality ones. They should be pretty tricky to get onto the wheels, requiring some leverage as you work them on, but they should be a very tight fit which will prevent them from moving. Sounds like the tires are too lose to me.
