(continued)

Spindle return spring (Fig. 15)

The spindle is equipped with an auto-return mechanism. The main components are a spring and a notched

housing. The spring was properly adjusted at the factory and should not be readjusted unless absolutely necessary.

1. Unplug the drill press.

2. Place a screwdriver into the loop (1) to hold the spring in place.

3. Loosen the two housing nuts (3) approximately 1/4" (6 mm). Do not remove the nuts from the threaded

shaft. Do not allow the spring or spring housing to slip out of control.

4. While firmly holding the spring housing (4), carefully pull the spring housing out until it clears the raised

notch (2).

5. Turn the housing so that the next notch is engaged with the raised notch (2).

 To increase the spindle return tension, turn the spring

housing counter-clockwise.

 To decrease the tension, turn the spring housing

clockwise.

6. Tighten the two housing nuts. Do not overtighten the two nuts.

If the nuts are tightened too much, the movement of the spindle

and feed handles will become sluggish.

Angular "play" of the spindle (Fig. 15)

Move the spindle to the lowest downward position and hold in place.

Try to make the spindle revolve around its axis while also moving it with a side motion. If there is too much

"play", proceed as follows:

1. Loosen the lock nut (5).

2. Without obstructing the upward and downward motion of the spindle, turn the screw (6) clockwise to

eliminate the "play". Note: A little bit of "play" is normal.

3. Tighten the lock nut (5).

Drilling depth (Fig. 16)

1. To stop the drill at a specific depth for consistent and repetitive

drilling, loosen the depth scale lock (1) located on the depth scale

hub (2).

2. Turn the hub until the pointer (3) is aligned to the desired depth on

the scale.

3. Tighten the depth scale lock (1). The chuck will stop after

traveling downward to the distance selected.

Note: All the necessary adjustments for the working of your drill

press have been done at the factory. Please do not modify them. However, because of normal wear and tear of your

tool, some readjustments might be necessary.
