Question about Porter Cable Variable Speed Quik Change Tiger Saw Kit 9746

1 Answer

The motor from my reciprocating saw started emitting smoke.

I took the saw apart and found a small black piece of plastic, roughly the size of a quarter but couldn't find where it came from. I cleaned the inside a little and put it back together but it just started smoking again. It seemed to have lost some power as well. The brushes looked fine to me.

    The piece of black plastic was nearly flat with a slight curve to it, maybe an inch long with two perpendicular fins attached to it about an eighth of an inch long. Rounded edges. It didn't look like it belonged anywhere. The windings didn't look damaged as far as i could see. My next step is to find a repair shop. I was mostly hoping that it was an easy answer like new bearings.

That small black piece, was it somewhat flat? I am thinking that it could be part of the fan or baffle. As far as the smoking when you had it apart how did the windings look on the armature and field? It is possible that this piece of plastic opened up the windings and there is a short in the electrical components. If that is the case I would suggest taking to a repair center to get is looked at. Let me know what you find

Why is my reciprocating carver leaking black goo?


Terri, this is grease leaking from seal on col-let shaft, or loose bolts/cracked casing. Take apart and repack gears and housing with lithium grease ( do not over pack) and change seal if possible.

Broken reciprocating saw blade stuck in saw


Hello, I found a very quick and easy solution to this. Pulling the blade release and shaking, and taking the saw apart, did not work. What worked instead was to simply turn the saw on while pulling the blade release at the same time - when I did that, the piece of stuck saw blade came shooting out. Please be VERY CAREFUL while doing this, making sure you are wearing eye protection and pointing the saw away from others, so that no one gets hurt by the ejecting blade piece. I would also suggest knocking and shaking the saw while holding the blade release before you try this, as another poster suggested, because if the blade piece is big enough it might come out this way, or at least it may help loosen it so that it will easily eject outward when you turn the saw on. Good luck!

After I use the saw a few minutes it begins to smoke. I turn it off,I don;t want to burn it up. there is a screw on each side that has a coil and a small piece of something black, but there is no oil in...


the small coil and black piece are the brush spring and brush. And NO you don't put oil there. If it is smoking I would look at the switch or the armature/field for your problem. It depends on where the smoke is coming from. UNPLUG tool and remove the brushes and rotate the armature by hand and look into the brush tube for the condition of the armature, if it is discolored or has a raised section then it needs to be replaced. Let me know if you need more assistance.

My coleman 18volt PMD8133XL drill smokes and has a burning smell when oressing triger


Hello, I hate when this happens to my tools. This could be a number of issues. I would think that the transistor that controls the motor speed is shot or the motor itself is loading the transistor causing the smoke, or the brushes internally of the motor are worn and causing the overheating, hence smoke. Is the unit new or well used?

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.
