CAUTION:
Avoid injuries. The next step involves
lifting the Head Assembly onto the
Column. The Head Assembly is heavy.
Have someone help you lift this as-
sembly into place.
8. Using two people, lift the Head Assem-
bly and insert the Column Guide (18) over
the Column (B1).
Slide it down on the Column Tube as far as
it will go. Align it so that it faces straight
forward, inline with the Base.
9. Insert one Locking Shoe (15) into place
inside the bottom of the Column Guide
(18), and the other on the outside of the
Column Guide. Tighten the Clamping Le-
ver (30) into the Locking Shoe at the base
of the Column Guide.
10. Adjust V-Belt (A1) tension or change
speeds.
- Open the Belt Guard (A25) to expose the
V-Belt.
- Loosen the Thumb Nut (28) to relieve
the V-Belt tension.
- If necessary, move the Belt up or down
on the pulleys to change the drill speed.
- Push the Motor backward, tightening the
Belt on the pulleys, and hold in place.
- Turn the Thumb Nut (28) clockwise to
tighten the V-Belt in place.
- Refer to the chart inside the Guard lid to
select speed and belt locations.
Note:
To test the proper belt tension, push
in on the center of each belt at its center.
It should move only 1/2 inch (in or out).
Caution: overtightening the belts can
cause the motor to bind, and not start.
It can also damage Motor bearings.
11. Locate the Feed Knobs (34) and Feed
Rods (35) and screw into the Hub (36).
12. Install the Chuck (A12).
- Thoroughly clean the tapered hole in the
Chuck and the Spindle (A15) shaft of all
dirt, grease, oil, and protective coatings
(paint thinner may be necessary).
- Slide the Chuck onto the Spindle shaft.
- Turn the Chuck sleeve clockwise and
open the jaws completely.
- Tap the nose of the Chuck lightly with a
piece of wood to securely set the Chuck.
13. Verify that the Table (B20) is square
(90 degrees) to the Head Assembly and
drill bit.
- Raise the Table to within four inches of
the Chuck.
- Place the long side of a combination
square on the Table.
- Align the short side of the square to the
drill bit.
- If the Table is not square to the bit, loo-
sen Hex Bolt (B12) with a wrench.
- Rotate the Table until it is square to the
bit.
- Retighten the Hex Bolt (B12).
