David,
More than likely, you have stripped the plastic gear inside. Those gears can sometimes be difficult to find and purchase. I would suggest trying to open up the top so that you can confirm if the gear is stripped. I would also suggest not putting as much paper through the shredder as they say it will handle. Hope this helps!

Some fixya user told me a website reliablestore it is very good.. I used it to repair my shredder it had some spark issue which wasn't easily fixed. you can go there and try
most shredder owners know aboutt it
it's free so no harm in trying

Is this a brand new shredder? sometimes they have a safety stopper you need to remove before using it.

there could be a thermal switch in the motor that is open cct check with a meter if you get continuity on motor wires

Interesting question --
I just picked up one of these over the weekend, and was able to get the flywheel off with minimal excitement. After removing the center bolt from the flywheel, I used a hammer to "encourage" the flywheel off the keyed shaft from the back-- through branch feed hole in the housing. It took quite some time, and I rotated the flywheel as I did it to keep it from binding up, but it eventually came off.

As an aside, would you let me know if you've found any source for parts or documentation? I'm going to attempt some repairs on the flywheel and chipper blades, but may end up wanting to replace them.

No spare parts are available....sorry

It could be one of two problems and they are both usually caused by over feeding. Either the tooth rollers have junped out of their sockets or they are jammed tight with paper which would cause the first to happen also. There are safety switches but unplug the unit any way. Get on the output side of the shreeder and start pulling paper or remove the metal object that was dropped into its throat. Hopefully, you won't have to take it apart to put the rollers back into their sockets.

When I recieved your reply to check the micro switch I found the contacts had built up a little
arcing on the points, I then filed the points and cleaned them with alcohol and put it back together
It works like new. If it bothers again i may try to get a new switch for it I owe you a large thanks
for the info to fix my problem
