Blade Change
Blades should be changed when they become
dull, damaged, or when you are using materials
that require a blade with a certain type or tooth
count.
To change the blade on the bandsaw:
1. UNPLUG THE BANDSAW!
2. Raise the head of the bandsaw to the vertical
position, close the Feed ON/OFF valve, and
remove the wheel access cover.
3. Remove the blade guard.
4. Loosen the tension knob in Figure 38 and
slip the blade off of the wheels. This knob will
be very tight and may be hard to loosen.
4. Install the new blade through both blade
guide bearings, as shown in Figure 39, and
around the bottom wheel.

Figure 39. Installing blade.
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 40, after
mounting to 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.
