BASIC OPERATION

Prior to Operation

1.Check the oil level, and if necessary fill to the mid point of the oil level window.

Basic Controls

Please refer to Figure 1 on page 5.

1.Raise and lower the Head by using the Head Crank (#4).

2.Feed the Spindle using Spindle Feed Handle (#16). Precise movements may be made using the Spindle Micro Feed Handle (#15).

3.Move or feed the table from side to side by using the Table Feed Wheel (#7).

4.Move the Table front to back using the Cross Table Feed Wheel (#13).

Adjusting the Head

1.To raise or lower the head, loosen the 2 heavy duty head lock nuts shown in the left part of Figure 3. Use the left side head handle to raise or lower the head on its rack and pinion mechanism.

2.The head may be rotated 360O by loosening the same bolts mentioned in item 1. Adjust the head to the desired angle, then fix the heavy-duty head lock nuts. Periodically check the tightness of these nuts, especially during prolonged use of the

machine.

3.You may set the head at an angle by loosening the three nuts shown in the right part of Figure

3. Retighten the nuts when you have set the angle at the desired degree. Refer to the scale on the right side of the head to read the angle.

Preparing for Drilling

Please see Figure 4.

1.Rotate the knob in the center of the spindle feed handle (#16) counterclockwise to loosen the spindle for vertical travel.

2.You can move the spindle vertically by operating the spindle feed handle.

3.For more precise movement of the spindle, operate the micro feed handle (#15).

4.For drilling blind holes (which do not pass through the workpiece), set the positive depth stop gauge (#14). To do so, first determine the desired depth. Then adjust the positive stop

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

5.For drilling holes that pass through the workpiece, set the stop gauge in its uppermost position. Page 7 SKU # 42827
