Topic tags/keywords: table saw kobalt height adjustment knob dado

Hello,

Yep, I bought a cheap table saw because I move every two years and didn’t want the movers to damage my Woodshop centerpiece. I’ve had a kobalt table saw from lowes for about 4 months, and it has worked awesome. Unfortunately I was doing some dado cuts and noticed the blade height adjuster began moving counterclockwise on its own as I cut boards. After fooling around with the handle and underneath the saw, I can’t figure out how to tighten the tension so it doesn’t move once I set the height. Does anyone have any suggestions on how to tighten the height adjustment so it stays set?

Thanks, will

I’ve got a porter cable from Lowes. Does the same thing. I’d be interested in any thoughts too… I posted a question about this and it seems that this is something that goes along without our “inexpensive ” saws… :(

Do these saws not have a lock knob for the height adjustment?

I seem to remember that those saws only lock the bevel angle, not the blade height… unless I’m thinking about a different saw. If you can’t figure out why it’s moving (and fix it), then I guess you could always try using one of these universal blade height lock attachment thingies:

Doesn’t matter if the saw cost 100 bucks or 1000. The blade elevation should not be moving when the saw is on. Call the company and see if there is a fix or return the saw. Lowes will take it back.

I don’t know if this is the problem, but when you set the height of the blade, do you raise the blade and then lower it to the right height, or do you raise the blade to it’s correct height ? When you lower the blade, you introduce slack in the rack mechanism. When you raise the blade, there is no slack in the mechanism.

+1 for what MrRon said – always raise the blade to the correct height. If the blade is still falling after that then there is something mechanically wrong. In a pinch maybe you could use a clamp to physically restrict the handle from being able to turn until you get a permanent solution figured out?
