# Ensure that sanding belts are not too tight or too loose. Never operate a sanding disk if the paper is loose. # Use the correct grade of abrasive material for the job. # Ensure that the distance between a circular sander and the edge of the table is not greater than 1/4 inch. # Do not push materials against sanders with excessive force. # Sand only on the downstroke side of a disk sander. # Do not hold small pieces by hand. Use a jig for pieces that are difficult to hold securely

Black & Decker Belt Sander suddenly stopped working.

Probably not.
It may have just had a part break inside, like the on-off switch, or one of the wires to one of the brushes, etc., etc.
I buy these regularly, and they are inexpensive, which also means they are made of inexpensive ( cheap) parts.
It wouldn't hurt to take it apart, knowing it may not be repairable. Sometimes parts are available on-line.
Be blessed.

Makita Belt Sander 9404 - dust collection bag not collecting the dust. Shooting dust out the front. What can be done to remedy this?

the tool needs cleaned thoroughly. there might be a section of a belt that has jammed the passageway. UNPLUG the tool and turn over to see on the backside if the clog is there, if not I would recommend using safety glasses and compressed air to blow thru the channels to dislodge the material. I havae also used a shop vac to help in this.

I replaced the switch the cord and checked the brushes everything looks fine but it won,t work. Help

Interesting. I looked at the following URL to see if there was any safety device that might prevent it from working and I see none:
If there is nothing happening when you pull the trigger, the only thing you can do is trace the wiring from the power cord through the trigger and to the motor contacts, as shown in the aforementioned URL diagrams. I assume the motor has not seized up on you since you did change the brushes. Not to sound foolish, but did you try changing the outlet you plugged the saw into? In some of the higher end equipment there is an inline fuse that is part of the AC plug assembly. Any chance that is part of the new cord? Blown or missing in-line fuses?
Please keep me informed of your progress as I find this quite interesting. Paul

Hello, the dust is not coming out into the bag

if you have compressed air remove the dust bag and blow thru every port and opening you can find. Make sure to wear safety glasses. Then I would run the tool with the dust port facing away from you, there is a buildup inside not allowing proper flow, you should empty the dust bag when half full for maximum performance.

Older makita belt sander shocking me while using

You are probably missing an insulating ring / washer that goes between your bearing and your armature (the shaft on the center part of the electrical motor. The fact that it does not have a grounded plug is not necessarily an indicator of age or safety so don't be too afraid. DeWalt still uses two prong cords to this day. In these tools they offer what is called double insulation, simply non-conductive material that separates electrical components from the user. The part number for the insulating ring is 681623-9. If you ever wanted to ground the tool you don't really need any special switches you just have to attach the grounding line to the metal casing.

Replace safety key?

I tried Tool Parts Direct, but their exploded view only shows the whole switch, which apparently includes the key. I'm not sure what the Hitachi key looks like, but if it's compatible with the ones Sears uses, I know they used to sell replacement keys in a blister pack (maybe 4 - 6 pcs) I bought a package of them from Sears several years ago.
You can also send a request for help to Hitachi customer support at:

My sander is vibrating very badly. So much that it is difficult to hold. Can you tell me what the problem may be and how to fix it.

I'm going to take a stab at this, with the following caveat from the Porter Cable manual:
  • For your continued safety and electrical protection, brush inspection and
    replacement on this tool should ONLY be performed by an AUTHORIZED
    At approximately 100 hours of use, take or send your tool to your nearest
    authorized Porter-Cable Service Station to be thoroughly cleaned and inspected.
    Have worn parts replaced and lubricated with fresh lubricant. Have new brushes
    installed, and test the tool for performance.
    Any loss of power before the above maintenance check may indicate the need
    for immediate servicing of your tool. DO NOT CONTINUE TO OPERATE TOOL
    UNDER THIS CONDITION. If proper operating voltage is present, return your tool
    to the service station for immediate service.
Having read their advice, also take a look at the diagram of parts in this link and see whether you feel comfortable disassembling something like this. You probably won't have to tear into the motor housing, but if it look dicey to you,please go to the home page of that same link and find a service center near youto do the work.
With that in mind, consider the following. I have the same sander, and have used it as one of an arsenal of sanders for many years. I think I remember having an issue like you describe, about ten years ago. Now if I can only remember what I did to repair it.....just kidding.
It's possible the bearings are worn out and need to be replaced. In that case, you might be better off having it serviced by a professional shop who can also replace worn brushes and clean and lube it to factory specs.
But it's also possible that the screw that mounts the metal pad to the bearing (#114 in dwg.) has come loose. I think that was the case with mine, and it was not the same sander, it vibrated so badly. I remember having a definite reason to tear into it, and I needed it for a job.
You might be able to access this screw by lifting a flap of the rubber pad and removing a dust seal, but if you feel adventurous, remove the four screws that hold the felt or rubber pad on the base of the sander. Be careful, because if you're not very careful you may have to replace this pad. (It should be readily available for a few bucks somewhere local, depending on your location.) In my case I made a custom cork bottom pad that was a bit stiffer than the foam rubber to keep my sanding sheet flat, but that's another story.
If you get this far, check to see that the center screw hasn't vibrated loose. If it's in tight, you need to check for play in the bearing that the metal base (#127, bearing & pad holder) is mounted on. If that bearing goes, the works will vibrate. Replace it if you can detect any play at all between the center race and the bearings. I'd change it out just for good measure if you have used the tool a lot.
Put everything back together carefully, tightening all screws with the right driver. And hope for the best!
I hope this is the solution to your problem. If you need parts, consult the web site listed above. They should be able to sort you out. Good luck! Let me know how it works out, or if I can help in any other way.
