    Q:Is it easy to change belts and do any come with belt sander?
    by|Dec 9, 2020

    Answer This Question

    A:  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

    by|Dec 11, 2020

      A:  Very easy to change the belt, just pull out the spring loaded lever (see photo) and the belt slides off. To adjust tracking a simple tension knob. Mine came with one 80 grit belt. This is a really good sander, quite the beast! good luck

      by|Dec 11, 2020

      A:  Not simple - housing must be removed. Don’t strip the the integrated screw holes! The tool does not come with spare parts. To note: the angle dust port pipe is made of plastic and will easily snap if you accidentally bump into anything when dust bag is rotated forward. This is IMO a significant design flaw that would keep me from buying this again.

      by|Dec 10, 2020

      A:  Thank you for your question. The 9403 includes (1) 4" x 24" Abrasive Belt, 80 Grit (742322-9-1). Changing the belt is simple. Just pull the lever all the way out to remove the old install the belt over the rollers, then return the lever to the original position. For more detail, please check the owners manual.

      by|Dec 10, 2020

        A:  Yea it’s easy to change. There is a lever on the side that will release the belt . An 80 grit belt came with mine

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

        A:  Thank you for your question, but we will require more specific information in order to provide an answer. Call the Makita Call Center during business hours at (800)4-MAKITA, they’re based in Buford, GA and are ready to help.

        by|Sep 25, 2020

          A:  N/A, one speed

          by|Dec 21, 2020

          A:  On this sander (like most) the speed is controlled via finger position (no setting indicator). On a variable speed belt sander, your question is answered by using a combination of factors including past experience, feel, visual feedback, material composition, the amount of material to be removed, desired level of finish, etc. which determines the specific grit of belt needed and speed used to accomplish the desired result. My advice is: buy a few extra belts, secure some scrap / test material and experiment with the tool. This is a professional grade sander capable of very aggressive removal of material with course belts at fast speeds, as well as high grade finishes at moderate / lower speeds with fine belts. Good luck!

          by|Sep 27, 2020

          A:  Hi, this is not a variable speed unit. It's all or nothing. This is a beast of a belt sander and will make short work of material removal. The user needs to be aware so as not to remove too much and get into trouble. For very heavy material removal use 36 grit, heavy removal use 50, normal is 80 with 120 being used when material is close to finish sanding. Good luck

          Q:Can this be used on a 70’s style wooden accent wall & smoothing an old ceiling that has currently popcorn ceiling.
          by|May 23, 2020
          6 Answers
          Answer This Question

          A:  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.

          by|May 27, 2020

            A:  Thank you for your question. The 9403 4" x 24" Belt Sander is not intended for overhead sanding applications. For additional questions, please call the Makita Call Center during business hours at (800)4-MAKITA, they’re based in Buford, GA and are ready to help.

            by|May 27, 2020

              A:  Yes, I’ve had mine for sometime now and to be blunt, it has enough power to sand the grey out of a sidewalk. I have no doubt that it could smooth the “popcorn” effect out of a ceiling, but you better start eating your Wheaties because it is a heavy, quite powerful piece of equipment which I can’t imagine holding over my head for the hours that it would take to clean up a ceiling in even a moderately sized room. I’d also suggest that if you decide to use it for such a job, that you hook it up for dust collection since it will make clouds of dust under those conditions. Moreover, given its power and aggressiveness, it would be challenging to provide fine control between closely spaced wooden details.

              by|May 26, 2020

                A:  Yes! I think it could but it can be rather aggressive so I'd be careful.

                by|May 25, 2020

                A:  I would not use my Makita belt sander on a ceiling because of the weight. The best thing for a popcorn ceiling is water (use a Hudson sprayer or equivalent) and a 6" drywall knife. Water is important because it will make the ceiling material very easy to remove and because some older ceilings may contain asbestos fibers. On a wooden accent wall, weight could also be a problem, but it would probably work OK. Personally, I think I would use a small orbital sander because it would be much lighter. You would have difficulty getting into corners with the belt sander.

                by|May 26, 2020

                  A:  Do NOT use it on popcorn ceilings. They contain asbestos and are dangerous. They should be professionally removed by guys in white suits and masks. Any dust from them can cause serious lung damage. Secondly .. on trim, if you are trying to remove old paint, your best bet is using a chemical stripper with lots of ventilation. This sander is great for many uses, but it is heavy and unless you are experienced, you can cause damage to the wood. Talk to your local paint dealer about options for removing old paint. If the wood is rough and you are hoping to smooth it, this machine might be what you are looking for. I don't recommend for sanding wood while it is installed. All work should be on a well supported flat surface so that you can control the sander and not cause gouging or stripping. Good Luck.

                    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.

                    So Far So Good
                    Sanded two projects, a table and a bench, worked great. Plenty of power, smooth action, belt easy to adjust and a long cord make this the best sander I've ever used.

                    Fantastic Machine - all metal construction
                    I bought this several years ago, BUT, mine was make in the UK, so I cannot speak for those made elsewhere. It is an excellent tool, well built and a very powerful sander. You have to be careful or it will run away on you! One caution. When I first bought it the sandpaper kept coming off, running to the edge. I called, and they said to make adjustments with a very fine turn of the adjustment screw. After that it was 100%. You may have to make an initial larger adjustment, but once close to being set, just minute ones. AND, get one of those crepe blocks to keep your paper clean. Not sure how they work, but they really work.
