Rated 5 out of 5 by from initial review of assembly Not too sure why there are all the complaints about the assembly instructions... other than having to flip from the written English instructions back to the common pictures a few times, the step-by-step directions were easy to follow. I have a generic 10" sliding compound miter saw and it mounted easily to the brackets and rides well on the stand and I cane move the entire saw from right to left on the stand as needed. I'll be putting this to the test over the next few months working in my garage / shop as well as travelling with the unit to job sites. I'll follow up with comments after I've used it enough to realistically comment on it. For now, I'll be looking for another set or two of brackets so I can swap tools as needed. All in all, seems to be a sturdy little fold up stand. Just what I needed for the small shop.

Rated 5 out of 5 by from Awesome to move around. I'm getting this for Christmas 2015 I put it together in about 40mins the only issue I ran into was that the Illustrations could have been a little bigger to identify the bolts and nuts. With enough common sense and knowledge you'll have no problem. I love it......AWESOME.

Rated 3 out of 5 by from NO INSIGHT First let me tell you that I have the AC9944 miter table and just love it. With that said, I bought the AC9945 for the price of $99.99 + tax. The miter utility Vehicle is awesome and performs to standards except for the cheap (000999131701 Saw Mounting Bracket Assembly. First the instructions say to place some sort of platform between the tool and the mounting brackets….. Really!!!!!!!!! That is because they are cheaply made “and will bend”. Another flaw is that ridgid could not make the table 2” wider to accommodate my other mounting brackets which means, I have to buy yet more mounting brackets and do a change over on my other ridgid power tools if I want to utilize this very nice miter saw stand. I hope with all sincerity that this was just an over sight on the team and not a got you move to sell more accessories. I have purchased numerous Ridgid power tool and have never had an issue until now and this is the reason I cannot give an overall 5 rating.

Rated 3 out of 5 by from Missing parts, horrible instructions The stand itself is great, but packaging could be way better. Parts were thrown in the box loosely. Nuts and bolts were missing. The Operator's Manual is horrible. Text on the first few pages, but the sketches are in the back?

Rated 4 out of 5 by from No Instructions & missing bolts I don't know why people are complaining about bad instructions, I had none!!! And the bolts to put the handles were the wrong diameter. I just looked at the picture and figured out the nut/bolt issue

Rated 5 out of 5 by from Great Product For those who want a large miter saw but don't want it to limit your bench space this is great. I keep mine attached and roll it around everywhere. Very functional, very practical, and very durable. I would love a second pair of brackets so I can put them on multiple saws with unbolting but unfortuately Ridgid keeps these hard to find and out of a practical price range.

Rated 5 out of 5 by from Great for a small work shop I replaced a Ryobi miter saw stand with this stand, the Ryobi stand was to hard for me to fold up and move by myself, it also did not stand upright on it's own very well either. I have a 12' x 20' work shop so floor space is very valuable and this stand allows me to easily fold it up by myself, wheel it into a corner with ease and frees up a lot of floor space for me when I am not using my miter saw. This stand is very well designed, very solid and very easy to assemble, mine did not even come with assembly instructions and for some reason my computer would not let me download the online manual, I figured it out by looking at a picture. I would highly recommend this stand to anyone with a shop or a mobile contractor. The online registration for the L.S.A. was also very simple, be sure you do that or you will not be very happy if something goes wrong when it's out of warranty.

Rated 5 out of 5 by from Great product! Works great. I've used it everyday for the last 2 months. Sturdy, durable. Only complaint was the setup directions. For the quality of the product Ridgid came up short. Bolts, screws, nuts, washers in different packages. No parts labeled.

Asked by: DUTCH7777

Would a 12" dewaltt dsw782 compound miter saw fit ridgid's mounting bracket without putting a plywood support?

Asked by: Angelo
Yes, most miter saws in general will fit this stand. Older Craftsman may require a plywood support or a model that has off center front and back mounting holes.

Safe to store upright with saw attached?

I have this Miter Saw Utility Vehicle along with the 12-inch sliding mitre saw (MS1290LZA). Is it safe to store the stand upright with the saw still attached to the stand? Will this cause issues for the stand or for the saw? Thanks for your help.
Asked by: Mike1348

Why do the mounting brackets for this stand not work with the 12" compound miter saw?

I have the 12" compound miter saw and first off, the assembly instructions are the absolute worst I have ever seen. Why would the written instructions be in the front, and then the diagrams in the back of the book? That means you constant have to flip back and forth. Second, the parts list couldn't be more unclear. All metric, with no picture so show what bolt, nut, etc... is being referenced. Third, the clamping brackets that go on the top of the stand do not work with the 12" compound miter saw. WHAT!?!? The back slots will allow you to insert the bolts, but the front ones don't because of the locking mechanism on the clamps.. The instructions say to you "1/2" material or greater and mount that to the brackets, then mount the saw to the material." REALLY!? Are you serious? So I have to go buy plywood to make this work? That is unacceptable. If this issue hasn't been addressed it should, because this is a horrible design flaw with a half-hearted attempt for a fix. Finally, I am missing parts from my kit. How would I go about getting them? How would I know what to call the part that I am missing since there is no picture accurately showing what the parts look like. I guess you could say I need a "dome top nut". The one that is used to secure the foot pad. I have to say, this stand is a huge disappointment and I wouldn't recommend it to anyone.

I just mounted a 12" Dewalt compound sliding mitre saw and it was simple. It is not necessary to attach the mounts to the saw prior to attaching them to the MSUV. Here is how I did it.... 1) Place the mounting brackets on the MSUV in their approximate positions (but not locked in place) and place the saw on top of them. 2) Position the mounting brackets to line up the mounting holes on the saw base with the slots on the brackets. Just lift the side of the saw slightly to move the bracket from side to side on the MSUV. 2) Insert the rear bolts through the mounting bracket and saw base and install washers and nuts just a few threads. 3) Slide the saw toward the back of the mounting brackets so the front mounting holes on the saw base are almost clear of the bracket locking mechanism. Insert the front mounting screws and install washers and nuts finger tight. (You may have to lift the front of the saw slightly to slide the mounting screw into position.) 4) Position the saw where you want it (front to back) on the brackets and then tighten the nuts using a wrench. You can also nudge the brackets from the sides so they are as far under the sides of the saw base as they will go before tightening the nuts. 5) Saw is now attached to the mounting brackets! Just lock the brackets in place on the MSUV and you're good to go! Easy Peasy!

I have extended my extension arm fully and cannot close it. the locking screw is loose ( also removed), but I am experiencing a mechanical block.

I have tried wiggling the arm to attempt to work around the stop blockage without success. Can you assist me in what might be blocking the arm and what the solution to my problem might be?

Will this fit the Jet 12" Sliding Compound Miter Saw Model # JMS-12SCMS / HD model numer 707120?

Asked by: Shane
Thank you for your interest in RIDGID. We have no specific compatibility information on the JET 12” sliding compound miter saw model with which to advise. The saw brackets for the RIDGID AC9945 MS-UV cannot accommodate every miter saw models design or foot pattern. For those models that do not fit, the option to mount to a mounting board and then to the brackets, is the only advisable option. Regards, RIDGID
