Shredder won't run unless Istrike it on the side.

Dear Sir,
Maybe, just maybe, I have an answer for you.
Somewhere on the part of your shredder that touches the bin, there is a tiny switch that touches the bin, and it is a safety switch that causes the shredder to stop working if the bin is removed.
In the shredder I have, and have had, the switch is usually plastic, and is the same color as the plastic body of the shredder.
Proper positioning of the bin to the "bottom" of the shredder is critical to it's working, as the bin presses on the switch to "close" it.
God bless your efforts.

As for your first part - It sounds like there is something wrong with the switch lever that moves to complete the electrical circuit to start the shredder. On every shredder I have seen, there is a little "bellows" linked up to this lever that pushes it back so the machine will shut off. Most of the time all you have to do is put another piece of paper in and let that get shredded and the shredder will stop afterwards. If not, then just use the main switch to turn the shredder off.
Second, the beeping during "mid-shred" sounds like a warning that the shredder is starting to overheat and shut down. If this is the case, just wait a few minutes to allow it to cool down and try to finish the shredding you have. I have found that if you feed a shredder a constant stream of paper to shred, this might cause the shredder to overheat.
Also, the shredder may get overloaded with pieces of the shredded paper. Here is the way to check on that:
1. UNPLUG THE ELECTRICAL CORD FROM WHEREVER YOU HAVE IT PLUGGED IN.
2. Lift the shredder from the bin and turn it upside down.
3. Look for an excessive amount of paper in the bottom of the shredder. If there is a lot, you can remove it in several ways. (Most likely the bin is quite full at this point.) Pull the majority of it out and put it in the bin. If there are pieces of paper that you can pull out with your fingers, use a tool (needle-nose pliers, serrated tweezers, a hemostat, etc.) to get those difficult pieces out.

Replace the unit on the bin making sure that it is the same way you took it off. In most cases (on the better shredders), there is a notch on the underside of the shredder that needs to be on top of a "nub" that is on the edge of the inside top of the bin. Unless that nub is aligned with the slot, the shredder will not work.

I found the nylon "bin full" flapper in the center of the head of the shredder is supposed to trip a microswitch indicating bin full. I removed the flapper and tapped on the switch. It came loose with a puff of paper dust. I replaced the flapper and it's back to good as new. Seems the dust built up around the switch and it was stuck.

Lube might not be necessary. Unplug the shredder from the outlet. Lift it off the shredded paper bin and turn it over. It is very possible that you have a jam. If this is the case, remove as much paper as you can making sure that you don't use anything that could do damage to the cutter'shredder blades. Once you have removed as much paper as possible, place the shredder back on the bin making sure that it is aligned properly. One way of making sure is to check for any space between the shredder and bin. If you do have space make sure that you replaced the shredder correctly on the bin; you may have to turn it around 180 degrees. When you get the shredder properly aligned, use the switch (DO NOT USE PAPER AT THIS TIME) to switch the shredder from Forward (shredding) to Reverse. You may have to do this a couple of times so be patient. At this point the shredder should be working in both directions. If so, move the switch to Auto or the center position and try a SINGLE sheet of paper. If it shreds that piece of paper, then you have fixed it. Be sure not to insert more paper than the shredder is rated for. Also, unless it specifically states that it can handle staples, credit cards, etc. do NOT let any of these items run through your shredder.
If none of the above works, buy a new one - :)

My boss has a shredder that will not run unless the bin is exactly centered in the bottom of the unit. There is a safety switch inside there, and a magnet to activate it. Make sure nothing is interfering with the bin or the shredder fitting together.
On other units, there is a slot that must match up with the shredder. It will only work one way. See of the shredder will turn around and put it on the bin the other way.

Try removing the shredder head from the bin and look for scrap of paper jamming up the blades.
Run it open, laid on its back.
Check visually for bent cutting blades.
Are the two shafts (with mounted blades) parallel?
A shaft may have come loose inside head assembly.

If your shredder has a feature where it won't run with the door open/shredder off the bin, you probably need to make sure that the safety is engaging properly. If the motor seems to sound very labored when it runs, unplug it, and check the blades to make sure there's not a lot of extra stuck in them. You may need to clean them and lubricate it with special shredder oil ONLY.

Make sure the bin is not full.
Make sure the bin is fully pushed in.
A shredder will not work if any of the safetys are not properly engaged and for good reasons.
