Powermatic PM2800B operating instructions Laser adjustment

Referring to Figure 20:

1.Disconnect machine from power source.

2.Pry off cap (H, Figure 20) and remove hex nut and two washers (I). Pull off hub (J).

3.Loosen two inner hex nuts (K) Do not remove.

4.Pull out slightly the coil spring cover (L) while firmly holding it. DO NOT allow the coil spring cover to turn freely in your hand, or the spring will unwind.

5.Rotate coil spring cover until tab (M) on the spring retainer engages the next notch in coil spring cover. Rotate coil spring cover counterclockwise to increase spring tension, clockwise to decrease.

6.Make sure coil spring cover is pushed back in, then tighten two hex nuts (K). Do not over tighten. The hex nuts should be tightened against each other.

7.Re-install hub, washers, hex nut and cap.

8.7Laser adjustment

Referring to Figures 21 through 24:

Do not look directly into the laser beam or view it directly with optical instruments. See Figure 21.

Figure 21

The Laser Assembly has been installed and pre- set at the factory. It should, however, be checked for alignment and any adjustments made before operating the drill press. It should be re-checked periodically, as long-term machine vibration may cause it to become misaligned.

1.Take a length of board (A, Figure 22) and draw a perpendicular line (B) on one side using a square.

2.Insert a small drill bit (C) in chuck (D), then place board (A) on the table on edge against drill bit with the marked-line side toward the back of the drill press.

Important: The table should be in horizontal position and locked. Verify that the line (B, Figure 22) is perpendicular to the table.

3.Connect power to the drill press, and turn on the laser using the button at the front of the drill press head.

Vertical Alignment

4.Use the socket head screw (H, Figure 23) located toward front of laser assembly, to adjust verticality of laser line. Turn screw as needed (2.5mm hex wrench), and move board side-to-side as needed, until laser light (E) aligns with board marking (B).

5.Adjust the other laser in the same manner. Two parallel laser markings should look like F and G in Figure 22. The distance between the lines will vary with board thickness; however, the lines must be parallel.

6.Place board (K, Figure 24) flat on table. Do not allow board to move from this position; use
