First you need to unplug the saw. Then you need to buy a blade to fit on the bandsaw, mines a 59.5 inch blade, you then neet to open the saw
You then need to loosen the top pully using the lever on the back then put then blade on the pulley
You need to fit the blade on the pullies, this may be tough. You need to then pull the lever on the back to tension the blade
You now need to make the blade track straight using the knob on top. You should use your hand to turn the pully
Once you have the blade tracking well, you should plug it in. Then you should close the cover. Then turn on the saw , but be ready to either turn off or adjust the saw in case something goes wrong. As its going adjust the blade, the saw should have a small "window" to view the blade.
And your new blade is on! Fell free to follow and or comment
