FEED DEPTH ADJUSTMENT
Turn the depth scale ring to the desired depth (Fig. 19 - 1). Lock the scale
ring in place with the depth knob (Fig. 19 - 2). The spindle will now stop
after traveling the selected distance.
SPEED ADJUSTMENT (FIG. 20 & 21)
This drill press has 12 speeds. The speeds can be changed by changing
the belt locations on the motor pulleys as shown in Fig. 21.
To change the locations on the pulleys, open the belt cover. Loosen the
wing screw (Fig. 20 - 1) on the motor support plate. Turn the belt tension
adjustment handle (Fig. 20 - 2) to loosen the belt tension. Then change the
belt's location to the desired speed.
QUILL SPRING ADJUSTMENT
The quill return spring may need adjustment if the quill starts returning
too slowly or rapidly. Make sure to wear gloves during quill spindle adjust-
ments to help prevent injuries from sudden and rapid disengagement of
the spring housing.
1. Loosen the screw and nut (Fig. 22 - 1 and 2), making sure that the
spring housing (Fig. 22 - 3) remains engaged with the head casting.
2. While firmly holding the spring housing, pull out the housing and ro-
tate it (counterclockwise to increase or clockwise to decrease the spring
tension) until the set screw (Fig. 22 - 4) becomes engaged with the next
notch on the spring housing. Turn the nut (Fig. 22 - 2) until it contacts the
spring housing. Tighten the screw (Fig. 22 - 1) against the nut to hold the
housing in place.
