Question about Dewalt Saws

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.

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.

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

The blower starts, whines then stops. At first it just whined and slowed down. Now it stops. When stopped the blower itself seems free.


If it is electrical,the blower motor is wore out and has no life left in it,no repairable part,when blower is moving the heat from bad motor is swelling and when cool will turn free. Please rate.jj505
