DRILLING HOLES TO DEPTH
Where a number of holes are to be drilled to exactly the
same depth, a depth stop is provided in the pinion shaft
housing and is used as follows:
1. DISCONNECT MACHINE FROM POWER
SOURCE.
2. Insert bit into chuck.
3. Lower the spindle until the pointer (C) Fig. 27, lines
up with the mark on the scale (D) you wish the depth of
the holes to be drilled. Then tighten lock screw (A).
Return the spindle to the up position.
4. Place the material to be drilled on the drill press
table. Raise the drill press table until the material to be
drilled just touches the drill bit.
5. Drill a test hole to check the adjustment and
readjust if necessary. All holes will then be drilled to the
exact depth as indicated on scale (D) Fig. 27. NOTE:
Scale (D) is calibrated in both inches and millimeters.
ADJUSTING SPINDLE RETURN SPRING
The spindle is automatically returned to its upper most
position when the handle is released. It is
recommended that the handle be allowed to slowly
return to the top position after each hole has been
drilled in the material. This spring has been properly
adjusted at the factory and should not be disturbed
unless absolutely necessary. To adjust the return spring,
proceed as follows:
1. DISCONNECT MACHINE FROM POWER
SOURCE.
2. Loosen nuts (B) and (E) Fig. 28. Make sure spring
housing (A) stays engaged with head casting.
3. While FIRMLY HOLDING spring housing (A) Fig.
29 pull out housing and rotate it until boss (D) is
engaged with the next notch on the housing. Turn the
housing counterclockwise to increase or clockwise to
decrease spring tension. Turn nut (E) until it contacts
spring housing (A), then back nut (E) out a 1/4 turn
from spring housing (A). Tighten nut (B) against nut (E),
to hold the housing in place. IMPORTANT: Inside nut
(E) should not contact spring housing (A) when
tightened.
