To remove the blade, ensure the power is dis-
connected and:
1. Loosen tension on the blade by turning the
tension control knob counterclockwise
when facing the front of the saw.
See
Figure 27 .
2. Remove the table insert and table pin.
3. Adjust upper and lower guide blocks away
from the blade.
4. Before handling the blade, put on gloves.
Open the upper and lower wheel covers
and slide the blade off both wheels.
Use
caution, the blades are sharp!
Changing Blades teeth are bent away from plane of the
blade:
Raker - The most common with one tooth
offset to the right, the next one to the left,
and the third is straight.
Wave - Will have 3-4 teeth bent progres-
sively one direction, then to the other in a
wave-like pattern.
Straight - Alternating teeth set right, then
left.
Blade Gauge and Material - Gauge is the
thickness of the blade measured near the
back edge. Generally thick blades are
wider and stiffer. The blade material can
range from carbon steel to spring steel to
bimetallic composition.
Blade Width - This is the measurement of the
blade from the tip of a tooth to the back
edge. The wider the blade, the less of a
radius it can cut.
Always select and use good-quality saw blades
and choose the right blade for the job. Discuss
your cutting requirements with your saw blade
dealer to make sure you are getting the type of
blade which best suits your need. 5. Rotate the blade 90° so it will slide through
the slot in the table.
