Best way to clear the vacuum path: remove the sanding belt and collection bag. Use an airhose to blow compressed air through the opening where the bag attaches to blow out anything that may be in the airway. After blowing through the outlet, check around the rear of the drive pulley for any wood that may have to be picked out. Reattach everything and try it again. If it still doesn't work, the vacuum is driven by a fan on the end of the armature. You'll have to take the case apart and check that to see if the fan blades have broken off or the fan has come lose from the armature.

SOURCE: Makita Belt Sander 9404

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.

Why isn't my new sander -blowing sawdust into the bag?


Check for internal blockage or possibly a defect in the discharge path.

Ryobi BE318-2 dust bag don't work


The pathway that the dust follows to reach the bag is most likely clogged. Take the bag off and look inside to see if there's sawdust plugging the orifice. If there is then you could vacuum out the dust or simply start up the sander and let the machine clear itself. If you do the latter just know that you will create a cloud of dust so do it in the proper environment.

The sawdust is not going to the bag. I've completely blown my sander with air and tried to unclog anything without taking the sander apart, but still all sawdust stays on the belt and not going up the...


The dust bags on most sanders are only marginally effective. They work OK on random orbit sanders with the holes in the sanding pad, but are next to useless on belt sanders. You might try attaching a vacuum cleaner hose instead of the bag. On the other hand, if the the belt is clogging up, that's not going to be helped by attaching a vacuum hose. The belt is "loading" up probably because the material you are sanding is damp, or maybe you are sanding paint, which tends to melt then stick to the belt. If you are just trying to keep the belt from clogging (or unclogging it), rather than keeping the dust contained, try running the belt against a wire brush after every couple of minutes. Good luck, Al K

Bag change indicater staying on and vacuum smells hot when using


I suspect there is a blockage somewhere along the pipes leading to the dust bag.
The bag full or bag change indicator measures how strong a vacuum is present at or near to the point where the bag is connected to the pipes. Under normal conditions an empty bag poses little resistance to the air passing through and therefore causes only a slight vacuum. A full bag poses a lot of resistance and therefore causes a strong vacuum which in turn makes the indicator show time to change.
If, however, there is a blockage somewhere, regardless of the state of the bag, a strong vacuum develops which causes the indicator to show as if the bag is full.
The hot smell is proably a result of the motor having to work hard trying to overcome the blockage.
Try to look into all the pipes - you may need to do a bit of dismantling and/or strech out flexible pipes to do so - to see if there's anything stuck. Also try some (careful and gentle !) poking through the pipes with something like an un-ravelled wire coat hanger, but take great care when poking through the flexible pipes as these can be ripped and then you'll have a differnt problem !

Delta 3hp tablesaw blade use to go down


There is probably a piece of wood or sawdust which is preventing the motor from cranking all the way down. Needs a good cleaning.

Dust bag won't collect


Try blowing through the little **** that collects sawdust (inside back by belt) with a compressed air nozzle, with the bag off, and squeeze the trigger and let the motor run a little. Blow out the insides as well as you can, including the air intakes for the cooling of the motor, and it should work fine again.
You can also blow out the bag to clean the pore in the fabric.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread. If I've managed to answer your question or solve a problem, please take a moment to kindly rate this post....thanks!

Grinder question


Use a pencil and straight edge to mark the cutting line on the wood. Place the wood on the saw table and line the mark up with the saw. Place the mark on the right side of the blade to ensure proper cutting. Plug the saw in and put on your safety goggles. Support the wood on the work surface with your left hand, placing it far from the saw blade. Place your right hand on the handle, and push the trigger to start the saw. Move the saw blade down onto the wood. Put constant pressure on the handle to slowly move the blade through the wood. Release the trigger and raise the blade once the cut is complete. Make diagonal cuts in the same manner, by marking the wood and lining the mark up just to the right of the saw blade. Continue as you would for a straight cut. Remove the wood from the saw. Unplug the chop saw and dust the sawdust off. Remove the dust bag from the back and empty it. Vacuum any remaining dust off of the saw.
