ASSEMBLY AND ADJUSTMENT
• Never operate this tool without the blade guard in place for
all through sawing operations.
• This adjustment was made at the factory, but it should be
rechecked and adjusted if necessary.
1. Remove the table insert and raise the blade to the
maximum height by turning the blade elevation handwheel
clockwise.
2. Remove the blade guard and antikickback pawl assembly.
3. Adjust the blade to the 0° vertical position by unlocking the
blade tilting lock knob and turning the bevel tilting
handwheel counterclockwise, and then lock into position.
4. To see if the blade (1) and riving knife (2) are correctly
aligned, lay a combination square along the side of the
blade and against the riving knife (making sure the square
is between the teeth of the blade).
5. Tilt the blade to the 45° position and check the alignment
again.
NOTE:
• This table saw is provided with a 10 in. diameter blade with
a body thickness of 0.07 in. (1.8 mm) thick with a kerf of
0.10 in. (2.6 mm ).The riving knife is 0.09 in. (2.2 mm) thick.
The blade diameter and the blade body and kerf dimensions
must be properly matched with the riving knife thickness.
• The maximum radial distance between the riving knife and
the toothed rim of the saw blade is 0.12 in. ~ 0.31 in.
(3 mm ~ 8 mm).
• The tip of the riving knife shall not be lower than
0.04 in. ~ 0.2 in. (1 mm ~ 5 mm) from the tooth peak.
• The riving knife is thinner than the width of the kerf
by approximately 1/64 in. (0.4 mm) on each side.
• The blade body must be thinner than the thickness of the
riving knife but the blade kerf must be thicker than
the riving knife.
6. Check the riving knife and blade alignment again at both
0° and 45°.
7. Replace the table insert, blade guard and anti-kickback
pawl assembly.
