Setting the Blade Perpendicular to the Sole Plate

This adjustment ensures that cuts are made square to the workpiece surface. This adjustment is completed at the factory and shouldn’t need to be adjusted unless the tool has been modified or serviced.

The most accurate method for checking the square of the blade is to make a cut with the saw and examine the resulting cut.

For even greater accuracy, the procedure below uses a method that amplifies a small measurement into a larger measurement to make it easier to observe. This doubles the accuracy of the adjustment.

Adjustment Procedure

1.Using the guide rail, carefully cut a small piece of wood in half.

This is a precision adjustment. Make sure the guide rail and workpiece are securely clamped.

The piece should be at least ¾ inch thick by 12 inches square.

The thicker the piece, the more accurate the adjustment will be.

For best results, the material should have a consistent center, such as Medium Density Fiberboard (MDF), plastic, or solid lumber.

2.Place the two pieces back together to verify that the original cut-line is tight (Figure A). If the cut-line is not tight, make a new cut.

3.Flip the offcut board end-for-end so the cut-line is still together but the board is upside down. (Don't flip the board that was under the saw.)

4.Inspect the joint between the two boards:

If there is no gap then the adjustment is correct.

If the gap is at the top of the two boards (Figure B), then turn the adjustment screws clockwise.

If the gap is at the bottom of the two boards (Figure C), then turn the adjustment screws counterclockwise.

5.Loosen the front and rear bevel lock knobs (see image to the right).

6.Turn the two stop screws in the direction determined in step 4. (Make sure to turn both screws the same amount.) Each turn of the adjustment screw will have the following effect:

1 turn equals 1 degree of adjustment.

1 turn equals ½ mm of gap between the boards shown above (assuming ¾ inch thick boards).

7.Verify the adjustment setting by repeating steps 1 through 4.
