Splitter Alignment
One of the most critical adjustments to help
avoid kickback is the splitter adjustment. It
should be checked and readjusted, if required,
after each blade change.
1. Lift the miter gauge bar slightly out of its
slot. Place a combination square against the
side of the raised up miter gauge bar and
slide the scale against the top of the blade
tooth and against the splitter as shown in
Figure 19.
2. Check the splitter for parallelism and for
clearance to the miter slot. If adjustment is
necessary, use the screws at the front
flange and at the rear splitter support.
3. Move the miter gauge to the opposite side
of the blade and using the combination
square, slide the scale against the top of the
tooth and the splitter. Again check for
parallelism and clearance. Clearance should
be approximately equal on both sides of the
blade.
Insert Adjustment
Adjust the setscrews in the insert with a 1/8 hex
wrench to ensure that the insert is stable and
flush with or slightly below the table top. See
Figure 20.
Arbor and Arbor Bearing Removal
1. To remove the saw arbor, first remove the
fence and rails, then remove the three
mounting screws holding the table to the
base (see Figure 15). Lift off the table.
2. Loosen the two set screws in the arbor
sheave (A, Figure 21) and remove the
sheave and key.
3. Loosen the set screw (B, Figure 21) on the
saw raising arm. The arbor assembly and
bearings will slide out of the arm housing.
Blade Raising Mechanism
Adjustment
If binding occurs, clean off all sawdust and pitch
buildup and re-lubricate with a good non-
hardening grease. If binding continues, check
the fit-up of the worm and worm gear segment.
The worm must be centered with the worm gear
segment. If it is not centered, loosen the saw
raising arm set screws, move the arm as
required, and re-lock the set screws. See Figure
22.
