Return Spring Adjustment, Laser Adjustment

Return Spring Adjustment

The return spring is located opposite the downfeed handle hub and sets the tension for the downfeed handle. It is adjusted at the factory and should not need further adjustment.

If adjustment is deemed necessary:

1.Unplug the machine from the power source. Referring to Figure 9:

2.Loosen the jam nuts (A) and hex nut (B). Do not remove.

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

4.	Rotate the coil spring cover (C) until the notch	Figure 9
	on the cover engages with the tab (E) on the
	head casting. Turn the cover clock-wise to
	decrease tension and counter-clockwise to
	increase tension.
5.	Tighten hex nut (B) firmly by hand against the
	cover (C), then secure by tightening the jam
	nut (A) against the hex nut (B).

Laser Adjustment

The Laser Assembly has been installed and preset at the factory. It should, however, be checked and any adjustments made before operating the drill press. It should also be rechecked periodically, as constant machine use may cause it to become misaligned.

To align (refer to Figure 10):

1.Place a small drill bit (D) in the chuck (C), then place board (F) flat on the table. Do not allow the board to move from this position; use clamps if needed.

Important: The drill press table should be in horizontal position and locked.

2.Bring the bit down until it leaves a slight perforation in the board (E) then raise it back up.

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

4.Using a 3mm hex wrench, loosen setscrews (A) on both laser assemblies (only the left side laser assembly is shown in Figure 10).

5.Adjust (B) so the laser line (G) crosses the perforation (O). Tighten setscrew (A).

Figure 10

6.Adjust the other laser assembly in the same manner until both laser lines form cross- hairs (G, H) exactly over the perforation (E) in the board.

7.Tighten both setscrews (A).

The laser is now calibrated properly and the location of your holes can be centered at the crosshairs for accurate drilling.
