Length of band saw for 7 1/2 black and decker band saw blade

Set up your band saw properly. There are several reason why band saw blade keeps on coming off on the wheels: loose/wear tire, improper guide adjustment, incorrect tension, over feeding wood stock or the problem could be on the blade itself. Try to change your blade, I got my band saw blades on sawblade.com . I suggest you watch band saw tune up tutorial videos on youtube. Hope that helps.

There are many reasons why band saw make noise. Here's are some "few checks" to do
1. Run the band saw without blade.
2. Run with a different blade.
3. Run the motor alone.
4. Check the bearings.
Another thing; incorrect speeds and feeds can cause noise and vibration.
Regarding about opening the motor, I can't help you with that. Try to check any other band saw motor manual reference.

I have Trajan 7x12 band saw, no vibration or noisy at all, I use Haltbar blade from sawblade.com

Just enter the serial number. If you have a chance, visit sawblade.com. I purchase my blades from them , great customer service and quality.

There are few reasons why blade jumps off, you may have a poor weld on the blade. Tension could be too tight or too loose. Make sure that the blade tracks properly. I advise you to watch videos about tuning up a band saw or check some informative blogs on bandsawblog.com. I purchased my blades on sawblade.com , check them out if you need any.

Just Google "band saw blades 52 3/4" for more information than you want. Most woodworking supply stores carry them.
Here's one: http://www.toolcenter.com/052_75_Band_saw_Blades.html

Open the case and look for stray wood pieces. Check the bearings for both wheels. Check the mounting of the lower wheel to it's shaft. Operate the saw by hand until the problem is fixed. Good luck!
