The bandsaw is useless – and dangerous – if the blade keeps slipping off. If your blade slips off after you exert additional pressure, yet the blade isn’t dull, then your blade may be falling off of the rubber tires. The last possible reason why your bandsaw blade keeps coming off is from wheel wobble.
A damaged rubber tier, worn wheel bearings, loose blade tension or a dull saw blade can cause the blade to slip off the wheel. If blade tension is okay, a dull saw blade could be causing the problem. If the saw blade is sharp and the blade slips off the wheel even when you only use light pressure to push the work piece through the cutting area, check the rubber tires for damage or wear that could lead to the blade slipping off the wheel.

The blade guides on the back of the saw blade should be removed temporarily so that you can observe that the band, when free running, wants to slowly drift towards the shoulder on the wheels. 03-05-2018, 10:20 AM #14 The blade on my band saw keeps walking off the drive wheel.
Here’s my problem, At 700 RPM I turn on the bandsaw and after a few secondsthe blades flies off. I’ve replaced dozens of blades blades on other bandsaws and never had a blade fly off. Just a couple of thoughts on why the blades and then the tire would come off the wheel(s).

Blade Tension Is Too Loose The most common reason why the blade is slipping off is that there isn’t enough tension to keep it on. If the saw blade is sharp and the blade slips off the wheel even when you only use light pressure to push the work piece through the cutting area, check the rubber tires for damage or wear that could lead to the blade slipping off the wheel. If you run the blade on the metal wheel itself, it will eventually wear the set off your blade and wear the running surface of the wheel.
You have to get the blade tracking in the middle of the tires with the blade guides backed off and not touching the blade, just keep turning the top wheel by hand and adjust the tilt until it tracks in the middle of the tire, then turn it on and make sure it stays there, then after your satisfied with the tracking of the blade set up your guides. If your blade is damaged there is a good chance you won’t get it to track properly, you would be better off to throw your old blade away and start with a new blade right from the start of the set up. P.S. you never said anything about the blade if it is the original ,I would suggest getting a new 1/2″ 3TPI blade and trying that first, thats the size of blade I run on my 14″ Delta for 95% of my bandsawing.

Are bandsaw blades universal?
Bandsaw blades differ in thickness, width, length, and tooth configuration. Length varies by machine, but the size of your saw’s wheels typically determines thickness and width: Smaller machines (9–12″ wheels) need thinner blades to prevent breaking the welds. They also accept only narrow blades, often 1⁄ 2 ” or less.

A majority of issues with wood burning is because of a dull saw blade. These blades may not be sharp enough to efficiently cut the wood, and thus create enough friction to heat and burn the wood. What is this? Dull blades make it more challenging to cut, which causes friction as you pass the wood through.
