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.
