Alignment, Align Rollers | Powermatic 511 instruction

Alignment

If the saw ever needs realignment, it should be performed in the following order:

1.Align rollers.

2.Align guides perpendicular to rollers.

3.Align blade parallel to guides.

To ensure accuracy over the full movement of the saw, construct a test square as follows, (Figure 17):

Use a 6-foot metal ruler and two 4-foot metal rulers (using the 3-, 4-, and 5-ft. measurements ensures squareness). Drill holes and attach the rulers with pop rivets or small nuts and bolts.

The 6-foot ruler is used to check squareness of the rollers. The 4-foot ruler is used to check squareness of the guide tubes.

Step 1: Align Rollers

The two outermost rollers are fixed, so adjust all other rollers to them. Place the 6-foot edge of the square across the rollers to check for alignment. The edge of the square should touch all rollers. If it does not, adjust as follows:

1.Clamp the straightedge to the top of the outermost rollers and flat to the frame. Position the clamps above the outermost rollers.

2.Turn each roller to ensure it does not jam or have excessive clearance from the straightedge. If this occurs, loosen the roller nut, shown in Figure 18.

3.The adjustable rollers have an eccentric hub. Turning the roller when the roller nut is loose changes the position of the roller. Turn the roller until it touches the straightedge, making sure the straightedge does not bend. NOTE: The roller panel may have to be loosened in order to turn the roller. See Figure 18.

4.When the roller is positioned, tighten the roller nut. NOTE: If a fixed roller has been replaced, the above procedure should be repeated.

5.Leave the test square clamped to the rollers for the next step.
