DRILLING DEPTH (Fig. 18)
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.
SPINDLE RETURN SPRING (Fig. 19)
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. If it needs to be adjusted, proceed as
follows:
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 (2) approximately 1/4"
(6 mm). Do not remove the nuts from the threaded
shaft.
4. While firmly holding the spring housing (3), carefully
pull it out until it clears the raised notch (4). Turn it until
the next notch (5) is engaged with the raised notch (to
increase the tension, turn it counterclockwise; to
decrease the tension, turn it clockwise). Tighten the
two housing nuts.
IMPORTANT:
Do not overtighten the two nuts. If
the nuts are tightened too much, the movement of the
spindle and feed handles will be sluggish.
ANGULAR PLAY OF THE SPINDLE (Fig. 20)
Move the spindle to the lowest downward position and
hold in place. With your other hand, try to make
it revolve around its axis with a side motion. If there is
too much play proceed as follows:
1. Loosen the lock nut (1).
2. Turn the screw clockwise to eliminate the play
but without obstructing the upward and downward
motion of the spindle (a little bit of play is normal).
3. Tighten the lock nut (1).
