Figure 21. Front to back shimming.

3. Secure the knobs and lock the positive

adjusting stud by tightening the checknut.

Ensure that the stud does not turn while

tightening the checknut. Set the angle

pointer to zero.

The table should also be 90° to the back edge of

the blade. If the table is not perpendicular to the

back of the blade, shim the table in the desired

direction with washers. Remove the trunnion

bolts and add washers between the table and the

trunnion so the table tilts in the desired direction.

See Figure 21. Electrical washers are a good

choice for shimming because they are very thin

and will allow fine adjustment.

Place Shims Here

The table can also be shifted side to side to

properly align the miter slot and the blade:

1. Loosen the 6 trunnion bolts underneath the

table.

2. Install the largest width blade available.

Lay a straightedge along the blade and

inspect it closely to make sure it is parallel

to the blade. Make sure there is no deflec-

tion of the blade from the straightedge.

3. Measure the distance between the edge of

the miter gauge slot and the straightedge at

points A and B. See Figure 22. Distance A

should be approximately equal to distance

B. Adjust the table slightly until these dis-

tances are equal.

Figure 19. Table in maximum left tilt position.

Figure 20. Checking blade to table.

To adjust the positive stop so the table will be

perpendicular (90°) to the blade:

1. Loosen the two knobs and the checknut

securing the positive stop adjusting stud.

2. Raise the upper blade guide assembly and

place a 6" machinist’s square or try-square

on the table against the blade. See Figure

20. Adjust the positive stop adjusting stud

so that the table will stop at a 90° angle to

the blade.
