4.Move the measuring device to the opposite edge of the disc and measure the distance to the miter slot.

5.Adjust the table by loosening the four attachment screws under the table, then move the table until the distance between the miter slot and the disc is equal on both sides (See Figure 17).

6.Tighten the four attachment screws.

7.Reconnect the electrical power to the machine.

8.4Disc table gap adjustment

1.Using a scale, check the gap between the edge of the table and the face of the disc. It should be very close to 3/32 inch. If it is much more or less than that distance, adjust it as follows:

2.Disconnect the electrical power to the machine.

3.Using the access hole on the top of the disc guard, locate and loosen the two set screws that secure the disc to the shaft.

4.Slide the disc in or out along its shaft until the table-to-disc gap is 3/32 inch (See Figure 18).

5.Tighten both set screws.

6.Reconnect the electrical power to the machine.

8.5Belt table miter slot parallelism adjustment

1.Disconnect power to the machine to prevent accidental start-ups.

2.Set the table angle to zero.

3.Place a scale or adjustable machinist's square against either the left or right edge of the belt or platen and measure the distance to the miter slot edge (See Figure 19).

4.Move the measuring device to the opposite edge of the belt or platen and measure the distance to the miter slot.

5.Adjust the table by loosening the three attachment screws under the table, then move the table until the distance between the miter slot and belt or platen is equal on both sides.

6.Tighten the three attachment screws.

7.Reconnect the electrical power to the machine.

8.6Belt table angle adjustment

1.Loosen the table locking handle and tilt the table upward to about 15°.

2.Flip out the stop bracket (See Figure 21).

3.Lower the table until its adjusting screw touches the stop bracket.

4.Place a machinist's square against the table and belt or platen.

5.If adjustment is required, turn the adjusting screw (Figure 20) until the table is exactly square to the platen.

6.Check the pointer. If it is not on 0°, loosen the pointer screw and adjust the pointer until it is on 0°.

7.Tighten the pointer screw.

8.Loosen the table lock handle and tilt the table until its stop contacts the 45° stop position.

9.Using a machinist's protractor set on 135° (90° + 45°) adjust the screw until the table and platen are in correct adjustment. DO NOT reset the pointer after this operation.
