Adjusting And Replacing Scoring Blade - Grizzly G0451 Instruction Manual

Adjusting and
Replacing Scoring
Blade
The scoring blade that is included with the sliding
table saw is wedge shaped. The kerf thickness of
this style of scoring blade is adjusted by changing
the height of the scoring blade. Most replacement
scoring blade sets consists of an inner and outer
blade with internal shims. The shims are pro-
vided so the scoring blade set can match the kerf
thickness of the main blade. Figure 59 shows a
replacement scoring blade set laid out for identi-
fication. For optimum performance, replace the
scoring blades when they start to get dull.
Figure 59. Scoring blade set.
To change the scoring blade:
1. Disconnect the saw from the power
source!
2.
Move the blade tilt to 0˚ (blade 90˚ to table),
and raise the scoring blade all the way up.
3. Move the sliding table all the way forward to
expose the internal blade guard that covers
the blades and riving knife.

4.
To remove the scoring blade, use the arbor
wrench to remove the arbor nut and arbor
flange (see Figure 60). Note—The arbor nut
has right-hand threads and loosens by turn-
ing counterclockwise.

5. Adjust the width of the scoring blade.
—If you are using a tapered scoring blade,
complete Step 6, then adjust the kerf as
instructed on Page 31 before continuing to
Step 7.
—If you are using a stacked scoring blade
set, measure the main blade and use the
shims to stack the set so the thickness
matches the thickness of the main blade.
6.
Install the new scoring blade, re-install the
arbor flange and the arbor nut, and tighten
them against the blade set.
7.
Move the orange blade guard back into its
original position, next to the blades, and cen-
ter the sliding table.
8.
Align the scoring blade set to the main blade
as described in the "Aligning Scoring Blade
Set" instructions on Page 31.
9. Perform a test cut and check for chip out on
the underside of the test piece. If there is
chip out, make the adjustments necessary to
match the kerfs.
