How to Clean and Calibrate a Jobsite Tablesaw - Tablesaw Tune-up and Maintenance

[@webcrawler3332]

One thing to note the miter gauge needs to have almost ZERO movement in order to get accurate readings

[@TheTranq]

Shimming it with tape works well for that

[@AllenReinecke]

Hopefully your miter gauge slots are a good fit with the miter gauge. These Dewalt table saws have a very sloppy fit ex-factory.

[@TheTranq]

I use tape on the side of the miter gage to ensure zero-play

[@andrewford80]

@@TheTranq I also use maskling tape and it works perfectly

[@falxonPSN]

Well done, sir! Yours is the only video I've seen showing adjusting the blade squareness at the trunnion. I think I got everything else dialed in on my new saw but even the manual didn't mention that I could adjust that. Time to rig up some way to test with my digital calipers.

[@316woodworks9]

Check the horizontal plane of the fence. Mine slopes in towards the blade on the top. If it's out going the other way, you can add a shim. I just made fence enclosure and it's as good as it gets.

[@andrewstallard1897]

I can't thank you enough for this video. I am very new to this hobby and I couldn't of figured all this out without this video. Thanks again!

[@simonmills2375]

Thanks. I just bought a de walt saw, mostly because it seemed from utube that they cut straight right out of the box. Mine really doesn't, but now thanks to your vid I know how to sort it. Appreciate it. Cheers from NZ

[@JustinShaedo]

Just wanted to say I've had the same experience, and these videos really helped me too. Cheers from rural Albury Australia.

[@campion05]

Im late to the party, but I still gave thumbs up. I have found my saw top has a dip right at the long sides of the throat plate. It's impossible to level the throat. The aluminum top has never had weight stored on it. Anybody else experience this anomaly?

[@aaronk9995]

I also had to drill out the screw but every time I add a nut and bolt the cam still moves no matter how hard I crank it down. Any thoughts?

[@64maxpower]

You know, I haven't had arriving knife in years. I realized from watching you that I never installed it and I've never given it a second thought

[@kenjacob3751]

Amazing... loosened the 2 hex nuts, gave a slight blow to the trunion, retightened hex nuts and I was square! Why did they not include this info in the manual? Thank you so much!

[@TheTranq]

Glad it helped!

[@chbelismail2183]

every think is good but still have blade wooble😢

[@tonybatista526]

❤ good vídeo I order de material but came from china no good to balance my table

[@LanceMcGrew]

The miter gage on my DWE7491 has way too much clearance to rely on mounting a dial indicator for tuning the blade.

[@TheTranq]

Mine did too! You have to use tape on the miter bar to shim it until it has no play

[@Stevesbe]

Wd40 is not lubricant

[@peterwareing1126]

All the videos I have watched they check the blade sits at 90 degrees, I can't find one that shows you how to tune the fence to 90 degrees vertically.

[@TheTranq]

Unfortunately the Dewalt has no built in adjustment to do this

[@thodgson13]

Good video! If anybody else is uncomfortable with using the mallet to set the saw blade (like I was), you can loosen just one of the bolts at the rear of the trunnion and it should pivot easily enough.

[@TheTranq]

Thanks for watching! You do have to loosen the trunnions screws either way, but just as tapping the fence allows for precise adjustments, it is the same as using the mallet on the trunnion! Recommended also by John White in the book

[@thodgson13]

@@TheTranq with one of the trunnion bolts at the rear of the saw still tight I found it to be pretty easy to make relatively precise adjustments. That being said, I know the mallet method is popular and I've never heard of anyone having any issues because of it. I just couldn't bring myself to hit it with one. Cheers!

[@kz.irudimen]

@@thodgson13 Honestly I'm pretty sure the kind of mallet hits you use to adjust it are less violent than just the vibrations from the motor itself when it's in use ...

[@thodgson13]

@@kz.irudimen Overall, perhaps, but they aren't focused in the same directions as the mallet blows are. I've never heard of any issues from using the mallet, it just doesn't seem to me like the way the designers of the saw would've intended.

[@stevejensen3471]

Great vid! I use the MasterPlate and SuperBar DI to align mine - super calibrated for flatness well beyond using a sawblade!

[@EggyOrphan]

I just got a used table saw and on one side of the table, there is kinda of a deep scratch. Does anyone know how I can fix it or if it'll effect the performance in any way??? Same model as this... Thank you

[@chiaweilin2545]

Thank you very much for the knowledge sharing. It's a awesome video and teach me how to calibrate my table saw.

[@TheTranq]

Thanks for watching!

[@efektmurowany]

Great manual for DYI's! Thanks a lot 🤝

[@matt69cp]

Great video mate. Just bought a Dewalt table saw similar to yours. Haven't used it yet as I wanted to make sure it was tuned properly first! Your video was exactly what I needed. Thanks very much for taking the time to make it! Cheers from Brisbane, Australia.

[@EggyOrphan]

Same here, just got a used one, same model so this is perfect! Thank you!

[@ukr4ever]

Same here :)

[@johnosullivan8068]

Clear and to the point good job ,do you have a link to the blade you used

[@316woodworks9]

Damn, you have the same setup and tools as I do. Same cart also. Most everything you said, I know and have done. The bottom line is the saw is a great workhorse but calibrating it to that of a cabinet makers saw if pretty futile. Everything from the fence not being 90 degrees up and down to the miter slots off because of the coating (Someone on YT does fine sanding and gets them really good) the whole top surface is not flat and just a little above a complete joke. I love the switch, the rack & pinion system and the colors. It's been through a lot. Most of all my precision measuring tools we purchased because of this damn thing. I do love it, kinda. Killer video man!

[@mychaelleesly]

Does the Freud 60T blade satisfy the DW7480 user manual's requirement to have a thickness less than the riving knife? Thanks

[@charlc]

Awesome video thank you

[@rayscrafield2106]

I am wondering if you could do a video or at least show your table saw stand. I have the Dewalt mobile base for mine but I want a more permanent base with out-feed table as you have. Could you show more of how yours is made? Thanks.

[@Kevinrichardsonministries]

Good... In depth... Thanks... Well Done...

[@davej1425]

Excellent excellent video. Thank you so much. First class. I'm going to go and do my saw now!!

[@kz.irudimen]

I was looking for videos to see if I missed anything doing maintenance on my saw, I found this one and another. Started with the other, first thing the guy says is to throw away the manual because we don't need that. Great, no need to go further to know that I'm not watching that. I then start this one, first thing you say is that bit about the manual :) Edit: now watched it, good video. Definitely agree that it pays off to take care of your tools, I don't have enough money not to care about my saw !

[@bigdaddy4975]

I’ve never seen a video on how to adjust the 90 degrees on the fence for this saw so that might be a good video to make.

[@TheTranq]

Thanks for the comment. Unfortunately, this model does not have built in adjustability on ensuring it is 90 degrees to the table, so it would have to be a DIY fix

[@crackerjack3359]

I have set the second position fence adjustment bolt way over to to the left hand side of the guide arm. It gives the flexibility I need to have the fence on either side of the blade.

[@thomashawaii]

My table saw’s two tracks are not parallel. That is why I can never use them at same time.

[@Snappergrabber]

Thank you, This is a great video, I found it extremely helpful.

[@Enpious]

Very Helpful

[@porsche606]

[@paulmagua6696]

[@rayscrafield2106]

Thanks for your video. You answered a couple of my questions so now I will tune my saw. First, buy a dial indicator.

[@frankkamolov3815]

Thank you.

[@carlwheeler3403]

Great video but I see a flaw in your setup. You used one mitre track to adjust the trunyon and you used the other miter track to adjust the fence. Did you check to make sure the miter tracks are parallel?

[@TheTranq]

Good observation! The miter tracks should be parallel from the manufacturer. If they aren’t, you’ll never get accurate results. That is a feature you are paying for in higher end saws

[@carlwheeler3403]

@@TheTranq I align both the trunyon and the fence off of the left miter track since it is the only miter track that I use and that way I will know that the blade is aligned with the fence.

[@TheTranq]

@@carlwheeler3403 that is a good idea! Ideally, the table saw will have parallel miter slots though

[@carlwheeler3403]

@@TheTranq yep, they should be parallel but they aren't always. It's just the way I do it, I sleep good at night knowing that my saw is perfectly aligned. LOL

[@andremoreira6188]

Amazing explanation video! Thank you very much 😊

[@johnlucus5468]

Best calibration vid Ive seen on this saw. Ive owned quite a few table saws at this point and just made the switch from a newer Bosch job site model to the latest Dewalt. What difference! I have to give it to Dewalt for thinking of the end user to this extent. None of these parameters are remotely adjustable on these types of saws and the parameters that are adjustable are a serious pain to do. I now have my new saw tuned up and it's giving me results on par with a pro level cabinet saw. Thank you for taking the time to do this

[@TheTranq]

@@johnlucus5468 thanks for the kind comment. I’m glad it’s working well for you cheers!

[@jsmcguireIII]

Unfortunately, the lateral free play tolerances on these miter slots make these types of adjustments more about precision than accuracy.

[@TheTranq]

I explain the video that you can use tape to shim the miter bar on your gauge so that there is no play

[@samanthaohlsen9670]

Best video I have watched on this subject. Thanks for taking the time to make such a great video!

[@susied8795]

My problem is that the cam that adjusts the tilt is all the way to the left but my blade is still higher than 90. I guess I can try to shave some material off the cam so that I can move the adjustment further over bring the blade closer to 90. Is there a better way?

[@TheTranq]

The cam is pretty thin as is. Is the saw new? If it can’t reach 90 degrees within the range of the cam I would take off the cam and replace it with a slightly smaller washer

[@bigdaddy4975]

That miter gauge and the slot have to much slop in it to check that with a dial indicator I have the same setup

[@TheTranq]

Yes you have to shim the miter bar using painters tape to get no play. I have a new product releasing on my Etsy soon so stay tuned there

[@YUSince]

Thank you for the great video🙏

[@CVYR490]

I love your video and explanation ! I actually own the same model 7491, 10" blade. i am about to buy this same dial indicator that you have. In ebay its ranges BTW my blade wobble, you can see when its coming to a stop, its arbour run out, about i think 0.2mm. After everycut, when you measure along the cutted piece, the measurement is out about 0.2mm between top and bottom, and in the middle of the cut piece, the measurement is out by 0.2 to 0.3mm, that explain the wobble. That is why i want to buy this dial indicator to test and adjust blade alignment and how much the blade wobble.

[@TheTranq]

Thanks for the comment. It’s worth investing in the indicator to make sure things are running properly!

[@DennyMK007]

0.2mm to 0.3mm difference??? That’s much thinner than one strand of hair. A lot of people would be extremely happy to get that precision. Did you mean 2mm to 3mm? Even that is not very much, but makes more sense if you want to make the most precise cuts.

There is also a small wobble on a spindle on these dewalt table saws. Idk how to fix that.

[@TheTranq]

If yours is new and has more than ~0.0025” of play on the arbor flange I would return it

[@TheTranq]

@@i.c.d.9512 you have to have a dial indicator jig that can rotate 90 degrees to check the arbor shaft

[@TheTranq]

@@i.c.d.9512 that is less than 0.001” - that is well within spec

[@BIGDW-ie8st]

How do you level the table of the saw?

[@TheTranq]

There’s no leveling capability for job site table saws. If you get a new one and it is not flat I would return it
