Motor whines, blade won't move

I use my DW304 10 AMP saw frequently. Recently it has started to whine when triggered, without the blade moving. When I bump the nose of the blade into something, like the wood I am cutting, the blade then begins to reciprocate. However, the saw no longer withstands ordinary stresses without freezing up.

SOURCE: Reciprocating saw stops reciprocating

your missing a tooth on a large round gear in the gearbox.

when the gear on the engine rotates into the position where the little engine gear spins because there is no tooth to come into contact with the engine runs but the gearbox doesnt spin, hence no reciprocation, but engine runs.

if you bump the blade it will start going again, but when you cut it will stop offasionally in mid cut. you can repair this but stop using it the engine gear will be destroyed otherwise

I have a dewalt dw303 that you can use for parts, I need a new trigger or something the motor is dead and I found a new saw. go to craigslist.org, rochester ny tools section and look for dewalt dw303 that is my listing. for ten bucks ill sell you all the gears you need. i think it is close to the same model, i am sure it is the same gearbox.

try opening your gearbox, im positive that is what is wrong.

SOURCE: Reciprocating saw-snapped blade-cannot be removed

What I would try is to spray some WD40 on the pin first and then see if you can find a small screwdriver or punch and try pushing the pin in further to release the broken blade. It doesn't sound as though it is anything major, maybe a burr on the side of the pin or possibly rust or debris. DON"T hit the pin because you might damage it or push it in and never get it back out. Looked at a diagram and it appears that they used roll pins to hold the clamp in place so it might be that one is cracked or mushroomed and you might have to drive them out. I suggest that you go to Searspartsdirect.com and type in your model number to look at the same diagram.

SOURCE: Reciprocating Saw / Stopped Working (No Response)

Many of my power tools that have stopped working, it has always been the "ON-OFF" switch that has been the proplem. Try blowing out the bugger, but watch that you don't loose some of the contacts. Never had brushes actually wear out, but did have one wire break off the brush.

SOURCE: Blade won't lock.

There is a ball lock in it and you have to twist the ball lock but if the ball lock is frozen generally WD40 will help unfreeze it and work it until the ball is free and should work just fine.

SOURCE: blade stuck in reciprocating saw

The pin is probably stuck in the blade. This happens from time to time after they get dirty. Take some WD-40 or some other type of penetrating oil and spray a little in the blade holder while working the release lever. It will probably free right up.

Nailer wont advance the nails then it shoots blank


Try ez test to check for proper operation. Remove nails and air supply, point nose of gun up then down again. The driver should not move from the top of cylinder position. If driver is moving up then down replace the driver oring. If driver oring seems ok then connect air supply and bump fire the nailer without nails against soft wood and door open so that you can see the driver and feeder moving. Bump fire the gun and make sure that the driver is moving all the way back up to top of cylinder and the feeder is moving rapidly back and forward. If movement seems ok then hold the nose down on soft wood and depress and hold the trigger. This will fire the gun but driver will stay at the bottom position and not return until you release the trigger or lift the gun. When holding the gun with the driver down position, no air should leak out the top or bottom of the gun. If air leaks out bottom, replace lower bumper, if air leaks out the top replace the upper bumper. Good luck

Wsc255 circular saw makes a whining noise when I start it up when I put the blade onto the wood the blade stops.


Either the motor is shot or the bearings are shot. Or both. You can buy replacement parts on eReplacementparts.com. It might be worth your time to just buy a new saw. Look on eBay.

Erratic starting circular saw


Sounds to me like you have a bad cord. Clamp the saw to a workbench so that it can start and run safely without you having to hold it. Put tape or a wire tie around the trigger to hold it in. THEN plug it in. Then move the cord around, especially near where it enters the saw. If the saw starts and stops intermittently you have confirmed the bad cord. Good luck.

Hitachi NR83AA shoots two nails on one pull of the trigger?


Best practice is to bump fire the gun to prevent double fire. Do not place the gun on the work and pull the trigger. This takes practice while using at an angle. Works better if the nose piece has rather sharp points to help nose to stay in postion while you bump. With trigger depressed, practice without nails bumping/hitting wood at different angles untill you can bump hit at the spot that you need the fastener. If the gun double fires while bump-firing, most likely all the safety/trip parts are worn/loose. Not expensive to replace. Good luck.

How does the framing nailer work with a black button grey button


Dewalt has two triggers available for their framing nailer. The black trigger (390746-00) is a bump style trigger. While holding the trigger, you will be able to fire a nail by pressing nose against work. This trigger is preferred by most framers because it is much faster. Gray trigger will only allow one nail to be fired. Bumping will not work with the gray trigger. With trigger released, you must place the nose against work then pull trigger to fire. To fire next round, you must release trigger, pull gun off the work, again place nose against work then press trigger. Check dewalt web site for recall information. Some dewalt framers have been recalled for faulty trigger. Good luck with your projects.

When I turn on the table saw, I can hear it humming as if the motor is hung up, but the blade does not move. With the power off, the blade turns freely. Also, I removed the belt and it makes the same...


With the blade and nut off the arbor, turn the motor on and VERY CAREFULLY turn or bump the arbor in the direction it is supposed to turn. If the motor spins up to speed you have a bad start capacitor. I have never been able to find start capacitors for Craftsman motors as a seperate part so you may have to replace the whole motor. Check with any local electrician shops first as they may have the capacitor you need.

When i pull the trigger, motor buzzez and sounds like its trying to go,...but its like its jammed up,...took the blade off and cleaned out,...still doing it,..please help


unplug the tool and try and rotate the spindle/blade by hand by using a glove on the blade. Does it move freely or is it tight? Then did you recently remove the blade and is the inner flange on? If it doesn't move freely I would remove the back motor housing cover to check the bearing condition and look for any obvious visible problems like discoloration of the field/armature. please let me know if you need more assistance before voting. Thank you

How do i change the blade in a reciprocating saw?


Hi,
Getting a broken blade our of the sawzall chuck can be difficult and require some ingenuity and patience...
Sometimes there be enough blade left so that you can grab it with a needle nose pliers... othertimes it is flush and that makes it more difficult... holding the chuck in the release position and rapping the saw against a table or with a hammer can jiggle the piece out....of course you have the chuck pointed down while you do that...
Also moving the piece around a bit with a stiff wire and also soaking the chuck and blade with WD-40 helps also....
Usually it will take a combination of these things and some persistance to get the job done...

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.
