My chipper shredder is jammed

My first thought is to make sure the unit is full of fluid in the drive.

you've found the right place buddy
I keep buying manuals from various websites so I can damn well help u in this..
what chipper is it btw? Like few websites have some manuals better while some have other brands better

sheared key in engine flywheel...to the shop...can't 101 ya thru it...needs alot of tools

go to http://www.searspartsdirect.com/partsdirect/index.action?intcmp=xsite_Sears type in your model look through the pictures and you should be able to find the part number and sears can order it for you.

You can download a PDF manual for your chipper at ( www3.sears.com ) Type your model number like this ( 247.795890 ) It will show you a parts list for it and also there will be a place that says "Manuals" click on that and it will download to your computer where you can either save it or print it out or both

This has happened several times for me and is usually caused by a peice of word jamed in the input hopper and half cut by the blades. Always make sure there is no wood in the input chute before stopping motor. remove the collector bag and use a long pry bar to reverse the flywheel. if this moves backwards you may then be able to remove the peice of wood jammed in the blades thru the input chute. Long Skinny arms is required to reach down the chute. Use a Flashlight to see if this is your problem.

If a branch was already being chipped when it ran out of gas...you must clear the hopper of any chunks of wood in it. Pull the plug wire and use a metal pry bar to dislodge any pieces of wood. when the flywheel runs free, put the plug wire back on and the choke on. Try it now!!!

Unplug the spark plug wire FIRST.  DO NOT SKIP THAT.  Then, WITH THE SPARK PLUG WIRE UNPLUGGED AND DISCONNECTED AND NOWHERE NEAR THE PLUG TIP, get a good sized stick, and try to turn the cutter wheel assembly in reverse.  I suspect you have a piece of wood stuck in there, and it won't come loose unless you turn the thing backwards.  You have to disconnect the spark plug because the engine could fire when you turn it.  Even if it doesn't start, one good kick could hurt you pretty seriously.  So, go unplug the spark plug and do your thing.

Most of our industry refers to chippers or chipper-shredders as pieces of equipment that can handle both wood and leaves. These machines have both a chipping device and a leaf-shredding mechanism. This mechanism is basically a hammer mill, cylinder or drum with a series of pivoting flail-type knives. The chipper-shredder usually is a smaller machine and may include a vacuum to clean up leaves. These machines can be self-propelled or stationary. Most chippers are disc-type, consisting of a large, heavy, rotating disc with knives mounted to it and are for chipping wood only.

Great input tina783. I have just one thing to add. Try to shred the branches within a reasonable amount of time. I found out that with my shredder, if I put older, dried up branches in, it tends to take a lot more time, as well as tosses chips back out at you. With newly cut branches, this wasn't nearly as much as an issue.
