adjustments.

1.Turn elevation wheel and raise blade as high as it will go.

2.Select a point on the body of the saw blade that is set to the left when viewing blade from the front of saw, and mark 1 with a pencil (Fig. 18).

3.Place the base of a combination square against the edge of the miter gauge slot, and extend the sliding rule of square so it just touches the marked point 1 on the body of the saw blade at the rear of the table.

4.Rotate blade and check the same marked point 1 of the saw blade at the front of the table (Fig. 18).

5.If the front and back measurements, shown in Figure 18, are not identical, loosen the four alignment bolts 2, located on the underside of the table at the front and rear of the saw with hex wrench supplied with your saw (Fig. 19 & 20). Carefully move the saw blade until the blade is parallel to the miter gauge slot, and securely tighten all four bolts.

Miter Gauge Adjustment

To check your miter gauge accuracy, move the miter gauge in line with blade and use a combination square to make sure the miter gauge body is 90 degress to the blade (Fig. 21).

To adjust the miter gauge for 90 degrees:

1.Loosen lock nut 3, adjustment screw 4, and lock knob 5.

2.Flip stop plate 6 down.

3.Rotate miter gauge body until it is 90 degrees to the blade.

4.Tighten lock knob 5.

5.Flip stop plate 6 up and tighten adjustment screw 4 until it contacts stop plate 6.

6.Tighten lock nut 8.

7.If pointer 7 is not pointing to 90 degrees, loosen set screw 8 on side of miter gauge bar and rotate pointer 7 to 90 degrees mark. Tighten set screw 8.

8.To adjust the miter gauge for 45 degress left and right, repeat steps 1-6, but use 45 degree stops.
