Blade Change

Blades should be changed when they become dull, damaged, or when you are using materials that require a blade of a certain type or tooth count.

To change the blade on the bandsaw:

1.UNPLUG THE BANDSAW!

2.Raise the headstock of the bandsaw to the highest position, close the Feed ON/OFF valve, and remove the wheel access cover.

3.Remove the blade guards.

4.Loosen the tension handle in Figure 34 and slip the blade off of the wheels.

4.Install the new blade through both blade guide bearings, as shown in Figure 35, and around the bottom wheel.

5.Hold the blade around the bottom wheel with one hand and slip it around the top wheel with the other hand, keeping the blade between the blade guide bearings.

Note: It is sometimes possible to flip the blade inside out, in which case the blade will be installed in the wrong direction. Check to

make sure the blade teeth are facing toward the workpiece, as shown in Figure 36, after mounting on the bandsaw. Some blades will have a directional arrow as a guide.

6.When the blade is around both wheels, adjust the position so the back of the blade is against the shoulder of the wheels.
