Saw Blades (Fig. V)

WARNING: Riving knives must be matched to saw blade dimensions in order to function
effectively. Refer to splitter and Riving Knife selection.
nOTE: THIS SAW IS INTENDED FOR USE ONLY WITH SAW BLADES 10" (254 mm) IN DIAMETER.
Fig. V
• The saw blade furnished with your new saw is a 10" (254 mm) combination blade, used for
crosscutting (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.
• 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.
• Use only saw blades designed for maximum safe operating speeds of 5000 RPM or greater.
• Saw blades should always be kept sharp. It is recommended that you locate a reputable
sharpening service to sharpen your blades when needed.
• 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.

CAUTION: To reduce the risk of injury, abrasive wheels or blades (including diamond) should
not be used on this saw.
Splitter and Riving Knife Selection (Fig. W–Y)

WARNING: To minimize the risk of kickback and to ensure proper cutting, the splitter and
riving knife must be the proper thickness for the blade used.
The splitter and 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 (plate) thickness and the blade kerf (cutting)
width marked on the blade or on the blade packaging. The splitter and riving knife thickness
must be greater than the body thickness and less than the kerf width as shown in Figure W.
