SELECTING SAW BLADES
Riving knifes must be matched to saw blade
dimensions in order to function effectively. See Riving
Knife Selection.
THIS SAW IS INTENDED FOR USE ONLY WITH SAW BLADES
10" (254 mm) IN DIAMETER. See Fig. 38.
1. The saw blade furnished with your new saw is a 10"
(254 mm) combination blade, used for cross cutting
(across the grain) and ripping (with the grain) through the
material. The center hole to fit on the arbor is 5/8" (16 mm)
diameter. This blade will produce a good quality cut for most
applications.
2. There are many types of blades available to do specific and
special jobs such as cross cut only, rip only, hollow ground,
thin plywood, paneling, etc.
3. Use only saw blades designed for maximum safe operating
speeds of 4,300 RPM or greater.
4. Saw blades should always be kept sharp. It is recommended
that you locate a reputable sharpening service to sharpen your
blades when needed.
5. Never stack blades on top of one another to store. Place
material such as cardboard between them to keep the blades
from coming in contact with one another, or place them in
storage drawer.
Abrasive wheels or blades (including diamond)
should not be used on this saw.
RIVING KNIFE SELECTION
To minimize the risk of kickback and to insure
proper cutting, the riving knife must be the proper thickness
for the blade used.
The riving knife supplied with this table saw is the correct size for
the blade supplied with the saw.
If a different blade is used, check the blade body, or plate,
thickness and the blade kerf, or cutting, width marked on the
blade or on the blade packaging. The riving knife thickness must
be greater than the body thickness and less than the kerf width
as shown in Fig. 39. If it is not, the riving knife MUST be replaced
with one that has the correct thickness.
The riving knife provided with this saw is either 2.7 mm thick or 2.8
mm thick and will be marked in one of two ways:
2.7 MM THICK KNIFE:
0.106" (2.7 mm) THICK RIVING KNIFE. ONLY USE FOR
10" (254 mm) Ø BLADE WITH 0.114" (2.9 mm) MIN. KERF
WIDTH AND 0.098" (2.5 mm) MAX. BODY THICKNESS
2.8 MM THICK KNIFE:
0.110" (2.8 mm) THICK RIVING KNIFE. ONLY USE FOR
10" (254 mm) Ø BLADE WITH 0.118" (3.0 mm) MIN. KERF
WIDTH AND 0.098" (2.5 mm) MAX. BODY THICKNESS
The riving knife available as an accessory marketed by DELTA is
marked as follows:
0.087" (2.2 mm) THICK RIVING KNIFE. ONLY USE FOR
10" (254 mm) Ø BLADE WITH 0.094" (2.4 mm) MIN. KERF
WIDTH AND 0.067" (1.75 mm) MAX. BODY THICKNESS.
(See Fig. 40)
All DELTA blade body thickness and kerf width information is
provided at www.deltaportercable.com.
If a different blade is used and the body thickness and kerf width
dimensions are not provided, use the following procedure to
determine the correct riving knife thickness:
1. Measure the body thickness of the blade.
2. Make a shallow cut in scrap material and measure the kerf
width.
3. Select the riving knife as shown in Fig. 39.

FIG. 41
4. Slide the riving knife through the shallow cut (Fig. 41) made in
step 2 to confirm the correct riving knife has been selected.
The riving knife should not bind or drag through the cut.
IMPORTANT: If any dragging or binding of the material
is encountered as it reaches the riving knife, turn unit off and
disconnect machine from power source. Repeat steps 1–4 to
make the proper riving knife selection before attempting another
cut.
