How do you remove the blade on tile cutter model mk470 mk diamond products, inc

Reverse lead should change direction

The motor on your tile saw is like a grinder, in the head is a set of gears, one on the armature and another at 90-degrees on the arbor. If the teeth on either or both gears are stripped off it will act and sound like you describe. When you move the motor or blade you are putting enough pressure on the gears that they touch enough to move the blade but it will never cut a tile. I have worked on these tile saws and have not been able to find parts for the motor to repair it. The entire motor is available on sites like www.ereplacementparts.com, part number 156428-R, but it's over $200 plus shipping.

The site above has blades for electric tile cutters.

Check blade is on properly. Remove blade and clean area where mounts to shaft. Make sure proper washers are in place. If blade is bent or wobbles replace. If blade is dull replace. Be sure you're getting enough water to saw. Don't force the tile through, let the saw do the work. Nothing helps any kind of saw more than a nice new blade.

Just use a rag and grab the blade. Unless the threads are messed up you don't have to hold the arbor still, just the blade.

Sometimes a blade that is set deep enough will walk in this manner, especially if it is a thin kerf blade like the MK Hotdog blade.

Also, a blade which has worn unevenly will do this too.

Not right. Readjust the water pressure or dirrection.

You can get a crack membrane to put over the cracks. First use a primer on the floor, this is a primer just for this application, then put membrane on top of primer. these products can be found at home depot or lowes or any tile store.Also do not use cheep thinset. the better thinset is more flexible and will absorb any movement. The cement board would not work as they will move or flex and cause the grout to crack and tile to loosen

take a pair of good vise grips and hook onto blade tightly, slide uo against back braket. that will hold the blade from spinning while you remove the nut, try bumping your ratchet/ wrench w/ a rubber mallet or hammer. hope this helps

options, change the blade, buy a more expensive blade, make sure the blade turns true when running, if not the armeture might bent inside the saw.
