Splitter Alignment; Insert Adjustment; Arbor & Arbor Bearing Removal; Blade Raising Mechanism Adjustment - Powermatic 66 Instruction Manual & Parts List

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 mitre 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 17.
2. Check the splitter for parallelism and for clear-
ance to the miter slot. If adjustment is necessary,
use the screws at the front flange and at the rear split-
ter support.
3. Move the mitre 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. Clear-
ance 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 18.
ARBOR AND ARBOR BEARING
REMOVAL
1. To remove the saw arbor, first remove the three
mounting screws holding the table top to the base.
Lift off the table top.
2. Loosen the two set screws in the arbor sheave
(A) and remove the sheave and key. See Figure 19.
3. Loosen the set screw (B) 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 20.
