THIS SAW SHOULD BE ASSEMBLED IN THE FOLLOWING ORDER: (FIG, 2, 4)

1.Make sure blade is installed correctly and arbor nut is tight. Use wrenches (U) stored on the tool. Refer to Figure 3.

2.Install and lock throat plate (Q). (NOTE: Adjust leveling screws before proceeding. Refer to To Assemble the Throat Plate.)

3.Attach the rip fence (R). (NOTE: Adjust rip scale before proceeding. Refer to Adjusting Rip Scale.)

4.Position the blade guard assembly.

5.Attach anti-kickback assembly to the guard assembly.

NOTE: To attach this table saw to a stand, please follow the instructions included with the stand assembly.

Tools needed for assembly include the wrenches included with this saw.

ATTACHING/REPLACING THE BLADE (FIG. 2, 4)

1.Raise the saw blade arbor to its maximum height by turning the blade height adjustment wheel (F) clockwise.

2.Remove the arbor nut (X) and flange (AA) from the saw arbor by turning counterclockwise.

POSITIONING THE BLADE GUARD ASSEMBLY/RIVING KNIFE (FIG. 5, 6) To position the blade guard assembly:

WARNING: Use the blade guard assembly for all thru-sawing.

1.Raise the saw blade arbor to its maximum height.

2.Install blade guard assembly by pulling the riving knife/guard release lever (L) and inserting splitter (M) until it bottoms out.

3.Release lever, make sure clamp plates are fully closed and the splitter is clamped securely. NOTE: Pull on the blade guard assembly/riving knife to ensure it has locked into place.

WARNING: Use the riving knife for non thru-sawing when blade guard assembly cannot be used.

NOTE: Follow steps 1–3 to install the riving knife (W) in the same manner as the blade guard assembly, Refer to figure 24.

WARNING: Before connecting the table saw to the power source or operating the saw, always inspect the blade guard assembly and riving knife for proper alignment and clearance with saw blade. Check alignment after each change of bevel angle.

WARNING: To reduce the risk of serious personal injury, DO NOT operate saw if riving knife or blade guard assembly is not securely clamped in place.

When properly aligned, the blade guard assembly/riving knife will be in line with the blade at both table top level, and at the top of the blade. Using a straight edge, ensure that the blade

(B)is aligned with the riving knife (W) or the splitter (M). With power disconnected, operate the blade tilt and height adjustments through the extremes of travel and ensure the blade guard assembly clears the blade in all operations and that the anti-kickback assembly is functioning.
