Need to know how to
I am not familiar with the Kett Car but I'll assume you've tried to see if there was an adjustment of some sort and you couldn't find one....So have you tried removing a link of the chain to shorten the chain? Chains can be shortened by taking one link out. Just realize that if you remove a link the chain may then be too short. So I'm not sure how much slack you actually have?
But to remove a link:1) Find the master link where there will be little clip on the outside of one side of the chain and remove that clip and save it. It should slide off with a little pressure.
2) The Master link with the clip removed (mentioned above) can be taken out and the chain will no longer be in a loop. Save the master link because you'll need to put it back together after.
3) To remove a link, using a file or a grinder...grind off the last link on eather side of the chain. Use your Master link to see how far or how many links you'll need to remove. Remember, the master link will have to go back in to make the chain a loop again so you want to remove the link in the right place and not remove any more links than you need to.
4) Once you find where you want to remove the link, If you can visualize the letter "H" as a chain link, where the cross bar is there will be a silver piece on each side of the outside of the chain. This is what you want to grind off just on one side of the chain.
5) You'll see how the chaing is put together and using a punch, you can tap out the center cross piece. What you should be left with is (if I could put these sideways it would be easier to show) an 8 on one end of the chain and an 8 on the other side.
6) The master link will go back into the ends of these and rejoin the chain. Master links and chainds can be bought at most hardware stores so if you cut off too much you can replace the chain or master link.
7) If you do need to get a new chain, take the old one with you so you can get the right size.
Where to find
Harbor Frieght sells wheel barrel tires that can be made to fit and they're cheap. You may have to put bushings in the new tires as they may be a little bigger (depending on the tire you buy) than the axle on the Kett car. Otherwise I'd say try the manufacturer.
Running machine will not start
Make sure you have power & its plugged in. Check the on/off switch & fuse. If you can't get it to work, get professional service.
Chain is locked
Sounds like it is kinked, or rusty. New chain is the best. Be safe. Vern
