Changing Spindle Speeds, Depth Stop | Powermatic 2800 specs

Table Extensions

Loosen the handles (C, Figure 15) and slide the extensions outward, then re-tighten the handles.

Changing Spindle Speeds

Change speeds only while the drill press is running.

With the drill press running, rotate the shift knob (Figure 17) slightly counterclockwise to loosen it, then push the handle left or right until the desired speed is displayed on the LED readout at the front of the head. Tighten the shift knob clockwise to secure the setting.

Depth Stop

The depth stop is useful for repetitive drilling of holes of the same depth.

1.Measure the distance from the tip of the drill bit to the workpiece. Add to this the desired depth of the hole in the workpiece.

2.Rotate the bottom nut (A, Figure 18) to this measurement on the accompanying scale.

3.Bring the top nut (B, Figure 18) flush with the bottom nut. This will prevent any movement of the bottom nut as it contacts the seat (C, Figure 18).

Alternatively, for less precise drilling, you can lower the bit to the desired depth, as shown in Figure 18, and tighten both nuts (A and B) against the seat (C).

Return Spring

The tension of the return spring (which raises the spindle after drilling) has been pre-set at the factory. No further adjustment should be attempted unless absolutely necessary. Should it become necessary, proceed as follows:

1.Disconnect machine from power source.

2.Pry off the cap (A, Figure 19) and remove the hex nut and two washers (B). Pull off the hub (C).

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

4.Pull out slightly the coil spring cover (E, Figure 19) while firmly holding it. DO NOT allow the coil spring cover to turn freely in your hand, or the spring will unwind.

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