New Jet Bandsaw Problem

I had powermatic bandsaw that had the quick release mechanism. When I changed blades I still had to lower the wheel with the tensioning knob. After lowering the tensioning arm
Have you checked the blades you fussing with are the correct length. Actually measured to see if it’s ——.
My powermatic took 93.5 I used mainly Olsen blades.
Good Luck

Likewise as AJ2. The saw blade tracking knob adjustment is loosened first so there is no thump. You then loosen the knob on top and then reverse for tightening. For most of the saws I own and owned, I had to loosen the blade adjust first to take tension off when taking off the blade. The tensioner arm is just to make it easier to tighten the blade but you still need to get the Tensioner knob on top to bring it close to tightness and then pull up the tensioner arm. To remove you will need to do the reverse but should not need to remove the screw completely. Sometimes it can stick and not slide down but surprised with a new saw unless it did not get any grease.

Its almost certainly a blade issue. Despite stated blade lengths, they very often arent exactly as described. If the stated length happens to be half way across a tooth, then the manufacturer will either go long to the next gullet, or short to the last gullet. the bigger the teeth the greater the difference. A 1/4” can be the difference between fitting and not fitting. Measure the two blades you have and compare.
Make a mark on the inside of the blade with a felt tip pen. Lay it on a straight floor and make a corresponding mark on the floor. Carefully roll the blade along the floor and make another mark on the floor when your blade mark goes flat. Then measure between the two floor marks. That is the ONLY way you can get an accurate blade length. I have to order blades 4 mm longer than the size stated on the machine data plate to get them to fit perfectly every time..

I have one that does a similar thing. I have found that all I have to do is turn the tracking wheel so the wheel leans forward and the blade will come right off. Then it is simple matter to adjust the tracking by spinning the wheels by hand before I power up. I then can, if needed, make a final adjustment.

ISSUE RESOLVED, but with no help from Jet.

Many thanks to those who responded. As suspected, however, something was majorly wrong with the tensioning and alignment mechanicals behind the upper wheel. As Jet was totally AWOL in a timely resolution of this manufacturing defect, the great folks at WOODCRAFT OF HARRISBURG, PA stepped up to the plate and exchanged the defective saw for a new one. Not only that, but Woodcraft assembled the replacement saw so as to prove that the replacement wasn’t defective as well. So, I suppose all is well that ends well.

Finally, I’d like to give a big shout-out to WOODCRAFT OF HARRISBURG, PA for great customer care in light of Jet’s failure to perform.
