Questions & Answers


What voltage does it need

Asked by Don December 21, 2020

This sander runs off normal household voltage of 110/120 and will draw 11 amps. very good sander, very happy with mine. good luck

Is it easy to change belts and do any come with belt sander?

Asked by Stephen December 9, 2020

yes it is, flip the lever the wheel retracts then pull the old belt out when you put the new belt on it will slide in place pretty easy, just don't jam it in there. Yes it comes with a belt on the sander, or at least mine did

What should the speed be set on for the sander paper grit ?

Asked by Battman September 24, 2020

N/A, one speed

Can this be used on a 70’s style wooden accent wall & smoothing an old ceiling that has currently popcorn ceiling.

Asked by RookieCarpenter May 23, 2020

It should work fine on the accent wall but you would then need to move to an orbital or finish sander. It would be to aggressive for the plaster on a popcorn ceiling. It is also pretty heavy to work overhead for long periods of time.

Will this sander be able to sand down high spots of wood subfloor for flooring installs?

Asked by Hec91 November 22, 2019

My guess is yes. We didn't do that but we did sand down our oak floors and they are finished beautifully. There were high spots and rough patches that we smoothed down.

Can this be used to oil sand wood

Asked by Patrick October 25, 2019

Hello! I'm not sure. To be honest. All actions can be compared at work. The main thing is not to spoil the tool.

Can i get this delivered to my local store (Rock Hill, SC) in one or two days ?

Asked by endurorider October 8, 2019

Maybe but I wouldn't count on it in two days. It really depends on where its shipped from. Call your local store and see if they can help you with that. If you just have to have it right now, I'd suggest going to a local tool store and buying it off the shelf, even if it cost a few more bucks. Good Luck. James

Could I sand a new wood floor with this before staining it. It will be a <100sqf room.

Asked by Phil August 28, 2019

Yes, this is a heavy duty unit.

Does this sander come with a carrying/storage case?

Asked by Denny May 29, 2019

unfortunately no, just a box. I will say that this sander is a beast and will mow through some wood very quick. So you need to be careful otherwise you end up taking too much off and getting into trouble. Good luck

Are the 4 x 24 sanding belts being phased out it seems I find more sanders 3 x 18 or 3x21

Asked by GD November 8, 2018

The 3" belts are more common, but 4" belts are still available. It may be necessary to order them online.

Used almost daily to sand steel doors. My previous 3 x 24 in” finally gave up after several years. We will see how long this one lasts. I hope several years as well.

I waited on this review for close to a year in order to put the belt sander to a consistent test. Having used it a lot (and many times really hard) I can honestly say that I couldn't be happier with the purchase. Do not be swayed by several reviews where folks are whining about the slip-on closer for the dust bag being "cheap" and "expecting more". It is not only simple in design but very effective and you don't have to worry about fine dust gumming up a zipper. Zero negative things or critiques. If you use a belt sander a lot on good sized projects like I do you won't be disappointed. Thanks Makita.

Best Sander for Quality, Power & Performance
I'd like to start by saying I've never written a product review before. However, I just wanted to let others know what my experience has been so far. Upon opening the box, I switched out the sandpaper for the grit that I wanted to start with. what a simple procedure that was, No worries about setting anything up, or dealing with tracking of the sandpaper or anything like it.. Was simple plug in and go to work. This sander is so Powerful and quiet, its an absolute joy to use, especially since sanding isn't such a joy to begin with. I'm a contractor and hobby woodworker, so this sander will see a lot of use. I didn't bother looking at any other sander, as this one fit the bill.. Yes, It's a little expensive. but you need to realize that this will most likely be a one time purchase, as it will probably out last YOU yourself. Cry once buy the best, never-mind the rest. The 9403 comes with a very long cord think 8' or 10' long which is perfect. be smart when using it, throw the cord over your shoulder in order to keep it out of your way. I purchased this to help me with the build of my new workbench top. This sander will come in very handy if you don't have the large expensive Planer's & Jointers. It'll allow you to purchase rough sawn lumber and be able to help you mill it down some. this sander just screams Quality!!! I'm very happy i purchased it. The only flaw I can find, is that it doesnt come with a coupler / fitting in order to hook up to the dust collection hoses. I'm using a Furnco 1 1/4" x 1 1/4" I recently found out that Makita does sell a Vacuum hose for this. Part # 192108-A I have enough hoses and it was a little disappointing that NONE of them worked plug & play. Be sure to pick up some Rubber Belt dressing sticks "Pro Stick" it'll clean your sandpaer and allow you more life to it, depending on what your sanding.

Awesome tool. It demanded a bit more "rolling up the sleeves", but after looking at continuous rental cost I saved a bundle. Super efficient. A flooring company still may be the best option. Yet and still, the sanding and staining allowed us to improve the look of old parquet floors dramatically.
