Powermatic 511 operating instructions Adjusting Crosscut Rulers, Alignment

Adjusting Crosscut Rulers

The panel saw comes with one rip (vertical) ruler and two crosscut (horizontal) rulers. The rip ruler is preset at the factory. The crosscut rulers should be checked and, if necessary, adjusted before operating the saw. Also, they may have to be adjusted after every blade change. With the blade installed, do the following:

1.Remove blade guard.

2.Loosen carriage locking knob and lower carriage down to the rulers.

3.	Using a square that measures at least 14" on	Figure 16
	one side, line up one edge of the square with
	the tips of the saw blade, and the other edge
	with the crosscut ruler. See Figure 16.
4.	If these are out of square, loosen the three
	bolts that hold the angle bracket to which the
	scale is attached. Slide the angle bracket so
	that its measure matches the measure on the
	square.
5.	Repeat the above steps for the crosscut ruler
	on the other side.
6.	Make a test cut to verify that the ruler is lined
	up correctly.

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 checkFigure 17 squareness of the guide tubes.
