Preparing for Drilling

Figure 3. Table Control Wheel

and Butterfly Lock Bolts.

Figure 4. Gib StripAdjustment.

1.The Chuck (#9) is installed on the Spindle (#10) using a Morris Taper. This is a self-centering design.

2.Rotate the Chuck Fixing Lever (#8) counterclockwise to loosen the Spindle for vertical travel.

3.You can move the Spindle and Chuck vertically by operating the Chuck Feed Lever (#5).

4.Vertical movement of the Chuck and Spindle can be limited by setting the Chuck Travel Limit Screw (#6). A Reference Scale (#7) indicates the relative travel of the Chuck.

5.For drilling blind holes (which do not pass through the workpiece), set the Chuck Travel Limit Screw (#6). To do so, first determine the desired depth.

Then adjust the Limit Screw so that the distance from the tip of the drilling bit to the end of the gauge is equal to the desired depth.

6.For drilling holes that pass through the workpiece, loosen the Limit Screw so it does not interfere with the vertical travel of the spindle.

7.Be sure that the Vise or other fixture used to hold the workpiece is properly attached to the table, and aligned with the drill bit. Adjust alignment using the vertical and cross table control wheels. The table can be locked into position using the four Butterfly Lock Bolts (#22) which are located under the Table on

the right side, and above the Cross-Feed Control Wheel.

Adjusting the Head

1.To raise or lower the head, loosen the Vertical Head Lock (#4). Use the Head Crank (#3) to raise or lower the head on its Gear Strip (#2) and Column (#1).

2.The head may be rotated on the column by loosening the Control Lever (#19). Adjust the head to the desired angle, then fix the Control Lever. Periodically check the tightness of this lever, especially during prolonged use of the machine.

Adjusting Table Slack and Compensating for Wear

1.Your machine is equipped with gib strip adjustment to compensate for wear and excess slack on cross and horizontal travel.

2.Rotate the gib strip bolt slightly counterclockwise to tighten the gib strip. Rotate it slightly clockwise to

loosen the gib strip.

3.Adjust the gib strip bolt until very slight drag is felt when moving the table.
