Blade comes off wheel on horizontal saw have a wilton 7040 horizontal saw. after cutting about 1/2 thrru a piece of metal the blade sticks and then stars comming off the right wheel and starts cutting into...
if its a new blade, make sure that it is the proper length for the saw, sometimes aftermarket blades look like they are the right size but the difference of a few mm can cause the blade to track. if its an old blade, it could just be dull enough that it is binding on the material you are cutting and this draws the blade off the wheels. even if the blade isnt that old or seems sharp, if you have a brand new blade handy that would be the easiest thing to try.
your manual will have instructions on how to adjust the blade guide bearings. if this is a new saw, it SHOULD be set properly and be working from the factory but they may still need to be adjusted. an older saw obviously may have shifted a bit from normal usage. if you dont have a manual one can be downloaded from the wilton tools website.
before adjusting the guides, though, check to see that the bearings spin freely. if they do not spin smoothly with minimum pressure, they need to be replaced. they also should be replaced if they spin VERY freely because this is also an indication that they are pretty worn and may actually be binding up under pressure.
