Fence Stop Adjustments

Periodically check the 90° and 45° backward (135°) tilt accuracy of the fence with an angle measuring device, such as an adjustable square or machinist’s protractor.

90º Stop Adjustment

Referring to Figure 14:

The 90º stop is controlled by the stop bolt (F) and the stop block (C).

1.Set the infeed table to approximately the same height as the outfeed table.

2.Move the fence by releasing lock handle (A) and pushing the fence assembly until it overlaps the tables.

3.Tighten lock handle (A).

4.Adjust the fence to a 90º angle by releasing lock handle (B), pulling up on the fence handle E), and tightening the lock handle (B).

Note: The stop bolt (F) should be resting against the stop block (C).

5.Place an angle measuring device on the table and against the fence to confirm a 90º setting (A, Fig. 15).

6.If the fence is not square to the table, release the lock handle (B), loosen the lock nut (D) that secures the stop bolt (F), and turn the stop bolt until the fence is square to the table.

7.Tighten the lock nut (D) to secure the stop bolt

(F) which retains the setting.

8.Tighten the lock handle (B).

45º Forward Stop Adjustment

Position the fence tilt lever (E, Fig. 14) toward the operator.

The 45 degree forward stop is controlled by the cap screw (G, Fig. 14). The adjustment is done the same way as for the 90 degree stop adjustment except that a 45 degree protractor is used.

45º Fence Backward Stop Adjustment

Referring to Figure 14:

The 45º fence backward stop is controlled by the stop bolt (H).

1.Loosen the lock handle (B).

2.Move the stop block (C) out of the way and position the fence at the 135º angle; fence tilt lever (E) is positioned away from the operator as shown. Make sure the fence sits against the stop bolt (H).

3.Tighten the lock handle (B).

4.Place an angle measuring device on the table and against the fence to confirm a 135º setting (B, Fig. 15).

5.To adjust, loosen the lock nut (J) securing the stop bolt (H) and turn the stop bolt until a 135º angle of the fence is obtained.

6.Tighten the lock nut (J).
