Was tearing an old crib apart, suddenly the blade stopped moving. No loud sound. Now Sawz-All motor runs but the blade does not move. I've re-chucked the blade, the shaft rotates freely and independently from the motor.
Don't see anything about this in the manual, I'm guessing from the other posts this is likely a shaft breakage? If so, is this generally covered by warranty? Saw is less than a year old and has seen only light duty.

Re: Motor spins, blade doesn't move
Yes it should be covered under warranty, it might not be a shaft breakage. there is a hex nut under the gearcase cover that might have loosened up. But I would take to a repair center first for warranty coverage. If you still have problems let me know.

You've either broke the motors housing moving the motor out of alignment or the impact on the blade has snapped the drive belt by the sudden torque or it's been jerked off by the sudden stop of the blade it's been yanked off the drive pulleys and the nose is the motor running free with no blade resistance you will need to open up and inspect the drive belt assembley system the blade drive shaft pulley access area and the motor access area to either replace the broken belt or refit the belt if it's not been chewed or damaged by the free spinning motor pulley the smoke it was proberbly the belt rubbing against the motors drive pulley or wrapping up around it burning it through friction Or your broke the motors drive shaft HOUSING allowing the driving motor and pulley to become misaligned dropping drive belt off The motor funny noise if a banging around sound then is was the still running motor pulley is bouncing around and rubbing against the deck ect. Causing the smoke if this has happened the impact with the stone has caused a kickback effect on the motor twisting it out of its housing breaking it's secure mounts meaning the decks motor is loose the housing has gone, the MOWER extremely dangerous as the motor can at the speed it's running at 3000rpm it will chew thought the rest of the deck in a matter of seconds throwing and ripping itself from the machine sending chunks of broken deck and the motor flying in all DIRECTION possibly causing injuries to any one within range and as the wires rip apart and a possible nasty and even fatal electric shock please for your own safety do not use the lawnmower Until it's been inspected by qualified personnel It is highly unsafe and should either be repaired or replaced which ever the cheaper Advice to check the area your cutting esp when using a high impact resistant plastic deck lawnmower for hidden foreign objects large and small stones as the small ones can be thrown by the blade like a "bullet"! small toys esp metal cars etcetra will make excellent shrapnel and cut the fabric grass box to ribbion it's also you if directly in the debris path Also not good for your lawnmowers blade or deck Pavement slabs are defiantly known as the silent MOWER DESTROYER YOU can't hear it, as you aproch you can't see it before it's too late, there's a Loud bang the MOWER stops that exact same instant and the MOWER IS NOW KNOWN AS BROKEN "! Esp on petrol mowers slabs tend to stop the MOWER dead bending the crank shaft the mowers with a slightly bentccrank will jump Round like it's on steroids or vibrate so badly it will shake itself apart as well as leaving a, very odd sensation in your arms Deposits from animals are just nasty to clean off the deck and wheels so I clear them up too if THERE are any just in case
It sounds like you have a problem somewhere between the motor armature and the reciprocating mechanism that makes the blade move up and down. Unfortunately the only parts Skill has available for your saw are the switch, cord, brushes and blade holder You'll could take it apart to see if something came apart that is repairable without parts. If you need parts like gears or motor parts, they are not available.
I just had this same problem. My andis Masters where working and they started making a loud sound and the blades stopped working. The Problem was there wasn't enough power. I used a screw driver and turn the power adjusting screw to the Right with a flat head screw driver.the sound got louder but after I keep turn it the blades started moving again and the blades got quiet again. Tada a Quick Fix.
sounds like the fan motor is at fault , 1 it could have bearing problems 2 the capacitors if it has are at fault , to correct check fan with out power to see if it runs free if it runs smooth then i suspect the capacitors are at fault , you will need a megger to check both items , make sure you check that they both accept a charge of 500 volts and that they discharge , if one does not , then change for a knew one ,
inside the motor/arbor section of the saw, there is a helical gear and worm drive on the motor. the front of the motor is supported by a bearing in the aluminum arbor section. sounds like most of the bearing balls are disintegrated and the worm disengages when a load is put on it but spins when there is no load. I would check and replace the front bearing.
There is usually a pin in the shaft of the motor, that corrosponds with a slot in the fan blades, it sounds to me like either (a) the pin somehow came out, or (b) the slot in the blades is rounded. Hope this helps
I have a Troy-Bilt gas powered hedge trimmer. My blades would not move. After tearing it apart, I found that there were some spacers under the 5 or 6 screws along the blades. These spacers are steel and designed so that you don't overtighten the screws. However, around those steel spacers, there is a teflon type material that makes the oval shape of the slot. That teflon had fallen apart and lodged so that the blades would not move. I removed the teflon and put the spacers back in and it now works fine. There is a little play between the spacer and the edge of the slot and it will probably eventually wear out but at least I got a few more cuttings off of it.
Sounds like teh capacitor has blown. These machines use normally use induction motors so they need the capacitor to take a charge and give the motor a kick in the right direction. You could CAREFULLY turn the machine on and spin the blade by hand. If it runs now then you will need a new capacitor.
