3. Turn the saw over and place it on a workbench or table with the
cord to the left, as shown in Figure 3.
4. Remove the blade from the pulleys first and then from the
blade guides. SAW BLADES ARE SHARP. USE CARE IN
HANDLING THEM.
5. Inspect the blade guides, shown in Figure 4 and remove any
large chips which may be lodged in them. Lodged chips can
prevent rotation of the roller guides and cause flat spots on the
rollers.
6. Wipe any chips from the rubber tires on the pulleys. This will
extend tire life and keep the blade from slipping.
7. Install the new blade as follows:
a. Position the blade so that the teeth are on the bottom and
angled toward the work stop, as shown in Figure 5.
b. Slip the blade into the blade guides, as shown in Figure 6.
thumb, soft materials usually require coarse tooth blades, while hard
materials require fine tooth blades.
For thick materials, coarse tooth blades work best because the large
gullets allow room for the long chips. You’ll avoid the chip welding
that fine tooth blades cause when the material is too thick.
For thin materials or sections, at least two teeth should be in the
cut. So use fine tooth blades in these applications such as tubing,
pipe, thin flat stock, extrusions with thin webs.
Where a smoother finish is important, select one of the finer tooth
blades.

Changing Blades
1. Turn off and unplug the saw.
2. Rotate the blade tensioning lever clockwise until it stops, as
shown in Figure 2, to release tension in blade.
