VARIABLE SPEED CONTROL

To avoid damaging the drive belts and pulleys, DO NOT turn speed control handles (A) Fig. 24, unless motor is running. The pilot wheel handles (A) are turned clockwise to increase speed and counterclockwise to decrease speed. The speed range is 500 rpm to 3100 rpm.

DRILLING HOLES TO DEPTH

Where a number of holes are to be drilled to exactly the same depth, the stop nut (A) Fig. 25, on the threaded stop rod (B) is used as follows:

DISCONNECT MACHINE FROM POWER SOURCE.

1.Insert bit into chuck.

2.Lower the chuck (C) Fig. 25, to the depth you wish the holes to be drilled. Then lock the quill in position by tightening quill locking lever (E). NOTE: Quill locking lever (E) is spring-loaded and can be repositioned by pulling out on the handle and repositioning the hub of the handle on the bolt located underneath the hub.

3.Depress spring-loaded button (F) Fig. 25, and rapidly move stop nut (A) until bottom of nut (A) contacts stop

(G). Then hold the pinion shaft handle and loosen quill locking lever (E), the chuck and quill will return to the up position by gradually allowing the pinon shaft handles to rotate to the return 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 depth and readjust if necessary by rotating stop nut (A) Fig. 25, for fine ad- justment. It is not necessary to depress button (F) while rotating stop nut (A) for fine adjustment.

QUILL ADJUSTMENTS

The spindle is raised and lowered by means of the pilot wheel (A) Fig. 26. The quill (B) can be locked at any desired point in its travel by tightening the quill locking lever (C). NOTE: The quill locking lever (C) is spring- loaded and the handle can be repositioned by pulling out on the handle (C) and repositioning the hub (D) of the handle on the bolt located underneath the hub.
