INSTRUCTIONS

Introduction
Install the Model T33448 on your G1023RL series
table saw for use with a thin kerf blade that matches the below specifications. The Model T33448 is
compatible with the existing table insert and will
reduce the risk of your workpiece pinching and
binding while performing non-through cuts that
require the removal of the blade guard.
• Riving knife MUST BE aligned with blade
and secured tightly. A misaligned riving
knife can cause workpiece to catch or
bind, increasing the risk of kickback.
• Use a riving knife for all non-through
operations, unless dado blade with less
than 10 in. diameter is installed.
A riving knife mounts just below the blade's highest point of rotation, as shown in Figure 1.
The height difference between the riving knife and
the blade allows the workpiece to pass over the
blade during non-through cuts (those in which the
blade does not cut all the way through the thickness of the workpiece.
The riving knife must also be kept within the range
shown in Figure 2. For these reasons, this riving
knife is only compatible with 10" blades, as listed
below in the Specifications.
