at the front of the table. Assemble the flange and arbor nut to the spindle and tighten arbor
nut (X) as far as possible by hand, making sure that the saw blade is against the inner washer
and the flange (AA) is against the blade. Ensure the largest diameter of the flange is against
the blade. Ensure the spindle and flange are free from dust and debris.

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.
