Powermatic 64B Adjustments, Switch lockout, Fence alignment, Blade raising/tilt mechanism

9.4Switch lockout

The table saw is equipped with a push-button switch that will accept a safety padlock, as shown in Figure 20. To safeguard your machine from unauthorized operation and accidental starting by young children, the use of a padlock (not included) is highly recommended. Place the key in a location that is inaccessible to children and others not qualified to use the tool.

10.0Adjustments

10.1Fence alignment

Before using the Accu-Fence®, verify that it is properly aligned with the blade. Consult the manual, no. M-2195075Z, that accompanied the fence.

10.2Blade raising/tilt mechanism

Do not try to force tilting mechanism past the 45º or 90º stops. This may cause blade to go out of alignment.

Refer to Figure 21:

To raise or lower blade, loosen lock knob (A) and turn handwheel (B) on front of saw until desired height is reached. Tighten lock knob. The blade should be adjusted about 1/8" above top surface of material being cut.

To tilt blade, turn lock knob (C) counter-clockwise to loosen, turn handwheel (D) until desired angle is obtained, and retighten lock knob (C).

10.3Miter gauge

Refer to Figure 22.

10.3.1Setting miter angle

The precision miter gauge has a rack and pinion adjustment for setting the angle. To operate:

1.Slide miter gauge into one of the slots on table top.

2.Loosen lock handle (A, Figure 22) by turning counterclockwise.

3.Pull out spring-loaded knob (C) and rotate knob until body (B) of miter gauge is at the desired angle as indicated on the scale.

4.Tighten lock handle (A).

10.3.2Indent settings

There are indents at the 0º, 30º and 45º right and left positions. At these settings, release knob (C) to engage stop rod. Then tighten lock handle (A).

Note: Do not rely solely on the indents for an accurate setting. After the stop rod engages at the 0º, 30º and 45º positions, make a fine adjustment with the knob (C) if necessary, setting it against the scale indicator (G).

10.3.3Extension plate

The extension plate (D, Figure 22) can be adjusted by sliding to the right or left or removed entirely.

To adjust, loosen two lock handles (E), position the extension plate and retighten lock handles. Make sure end of extension plate is not in the blade’s path.

NOTE: The lock handles (E) are adjustable. Pull out on a handle, rotate it to different position, then release, making sure it seats itself upon the pin.

To remove extension plate, slide it completely off and remove lock handles (E) and mounting hardware.

10.3.4Calibration

1.Place miter gauge in one of the slots on the table top.

2.Set miter gauge at 90º to blade (0º setting on the scale) by loosening lock handle (A), then pulling out spring-loaded knob (C) and turning the body (B) until 0º is indicated on scale.

3.Measure the accuracy of the gauge against the slot with a combination square.

If adjustment is necessary:

4.Adjust body (B) until it is perfectly square (90º) to miter slot.

5.Tighten lock handle (A).

6.Verify that scale indicator (G) reads 0º. If further adjustment is needed:
