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.

Rated 5 out of 5 by from Good Quality I read several reviews regarding the problem with assembly instructions - - Here's where I feel the problem is - the actual instructions with pictures are in the BACK of the manual - not considering with the front pages of instructions. Assembly is EASY EASY - even without the proper instructions - - all you really have to do is look at the picture on the box and you'll be OK - but if you are one of those who follow step by step - then those are in the back few pages of the manual I've gone through several portable or mobile work stands - this one is TOP NOTCH - quality wheels, allowing easy use push and pull through grass or dirt -- - for me, I put a RIDGID sliding compound miter saw (12 inch) and it moves quite easily.

Rated 3 out of 5 by from INSTRUCTIONS ? What????? In my 59 years I have NEVER seen such a poor excuse for assembly instruction!!!! I sell and assemble residential products for a living and have never seen such poorly thought out assembly instructions and unidentifiable parts!! Looks like a good product but fire your product manager who totally missed the boat and left us all to struggle with the product assembly.

Rated 2 out of 5 by from Not very excited So I went to Home Depot this evening excited to get a new saw. I ended up purchasing a Ridgid 12" Double Bevel Sliding Miter Saw. Very Cool. I realized I would also need a stand, so why would I purchase anything else but the Ridgid MSUV?? Stands to reason it should bolt right up being made by the same mfg, Well I guess that was a stupid assumption….Really?? I have to bolt my $400 saw to a piece of plywood to secure it to your MSUV….That is unbelievable….And there is no way to engineer another bracket to work with this saw??? I mean I would be willing to pay even more money to not have my equipment looking like some cobbled up junk I picked up at the local pawn shop. Guess I'll do a little more research in the future before I make a purchase. Please contact me with a resolution. If not I will gladly return this to the store and exchange it.

Rated 5 out of 5 by from Caught Everyone's Eyes I first used the Ridgid MSUV on a pre-cut for a Hands of Mercy build project. I had a piece of junk saw attached that was made fun of, but the stand was loved by all. I'll be purchasing a Ridgid Double Compound, Sliding Miter Saw to attach for the next pre-cut or handyman ministry project at church. Highly recommend.

Rated 5 out of 5 by from Excellent features. I purchased this stand after viewing others four years ago. I am impressed with the way it sets up and folds down. It will store in a small area. The wings work smoothly and are strong. I would buy another and recommend it to anyone.

Rated 5 out of 5 by from best ever, easy to use and solid. this stand is use with my RIDGID 12 inches miter saw and it is a pleasure to work with. each side could be extended to support long beam.

Rated 4 out of 5 by from This is a great additon to the Saw. If your going to purchase a large miter saw, you need to get this stand or the AC9944. It has supports for the outrights. This one does not. I give it a four out of five for durability. If you cut trim you are fine with this one, but 2x8 or up are a little heavy for this one without the uprights.

Rated 5 out of 5 by from Great portable stand I love my Miter Saw Utility Vehicle. I use it to store and transport my Ridgid 12" sliding compound miter saw. It's easy to stand up and store my saw in my crowded shop, and the big tires make moving the heavy saw over the job site effortless. The stand quickly and easily raises into position to give me a sturdy work station. I love the adjustable out feed supports on either side of the SUV. I can support even long boards while I make accurate cuts. I highly recommend this product, whether you use your saw in your shop or out in the field, this portable stand will really make woodworking enjoyable and convenient.

Rated 5 out of 5 by from Easy to transport and set up miter saw I have a Dewalt Miter Saw that I mounted to this stand because it was easier to set up and move than Dewalt. Nice Sturdy Feel about it. Easy to move like a dolly.

Rated 5 out of 5 by from Great Stand! Easy to put together. Very durable and easy to use. Best value compared to Bosch or Makita stands. Ridgid was probably the first to come up with this design and now there are lots of imitations.

Rated 5 out of 5 by from This Miter Saw Utility Vehicle is a very sturdy platform and it is quick and easy to set-up. I have owned my Miter Saw Utility Vehicle for over 5 years now and I would definitely buy another whenever I upgrade to a newer model miter saw. It has served me well and I highly recommend it to any serious carpenter or woodworker. The upright storage position is great for saving space in your workshop or studio.

Rated 4 out of 5 by from Handy as all get out an awesome product!!! not as durable as you may want for everyday use but the portability of this more than makes up for its faults. If planning on storing the saw on the folded frame adding a hose clamp between the quick detach and the frame holds it way tighter for the trailer rides between job sites. cons: the plastic catches on the extendable arms would definitely benefit if made from a stronger material. I have broken twice using the saw and stand for moldings .

Rated 5 out of 5 by from A great overall stand The AC9945 is a very good miter saw stand. It is durable and easy to use. I do have a back issue and find it a little difficult to stand up but for the normal individual it would be perfect. I can fold this stand up and tuck it in the corner of my garage. I would definitely recommend this stand.

Rated 5 out of 5 by from This Portable Miter stand is very handy Bought this Miter stand at Home Depot. Looked at other brands and this one had the best features for the price. It is very easy to use and work's great at the work site. Had one problem with one of the locking clamps for the extending table supports, It broke but received a new one at no cost. Would buy another one if I need to but this one will last me a long time. Great Portable Stand!!!

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

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.
