Blade Changes
Change blades when they become dull, damaged, or if the operation requires a different type of blade.
To change the blade:
1.DISCONNECT BANDSAW FROM POWER!
2.Raise the headstock, then remove the wheel access cover.
3.Loosen the tension knob and slip the blade off of the wheels.
4.Scrape any buildup or debris off the wheels.
5.Install the new blade through both blade guide bearings, as shown in Figure 19, and around the bottom wheel.

6.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 it will be installed in the wrong direction. Check to make sure the blade teeth are facing toward the workpiece, as shown in Figure 20, after installing it on the bandsaw. Some blades will have a directional arrow you can use as a guide.

7.When the blade is around both wheels, adjust the position so the back of the blade is against the wheel shoulder, as shown in Figure 21.

8.Tighten the tension knob so the blade will not slip on the wheels upon startup.
9.Connect the bandsaw to the power source.
10.Briefly turn the bandsaw ON then OFF to position the blade and resume the previous tracking.
—If the tracking needs to be adjusted, see Blade Tracking on Page 38.
