Metal cutting band saw

the saw is used properly, if the guides do get out
of adjustment though, it is extremely important to
readjust immediately. If improper adjustment in
maintained, the blade will not cut straight, and if
the situation is not corrected
it
will cause serious
blade damage, because guide adjustment is a
critical factor in the performance of your saw, it is
always best to try a new blade to see if this will
correct poor cutting before beginning to adjust. If
a blade becomes dull on one side sooner than the
other, for example, it will begin cutting crooked. A
blade change will correct this problem the guide
adjustment will not. If a new blade does not
correct the problem, chick the blade guides for
proper spacing.
