Assuming you need to move a band saw from one location to another, the best way to transport a band saw is by disassembling it and then reassembling it at the new location. This process can be time-consuming, but it will protect your saw and make moving it much easier.
To start, unplug the band saw from any power source. Next, remove the blade guard and table insert. Some models also have a light that needs to be removed at this time. With those parts removed, you should be able to see the blade. Carefully remove the blade by loosening the tension knob and sliding it off of the wheel pulleys. Once the blade is off, you can remove the upper and lower wheels.
The next step is to take apart the stand or cabinet if your model has one. You will likely need a screwdriver or wrench to loosen some bolts so that you can separate the pieces. If possible, label where each piece goes so that you can more easily put it back together later on. With everything taken apart, you can now safely transport your band saw to its new location.
When you arrive at your destination, begin by putting together the stand or cabinet if applicable. Then reattach all of the wheels before adding back on the blade. Be sure to tension the blade properly before putting back on the guard and table insert. And finally, plug in your band saw and test it out to make sure everything is working as it should be!
