The spindle is automatically returned to its upper most

position upon release of the handle. It is recommended

that the handle be allowed to slowly return to the top

position after all holes have been bored 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:

WARNING: MAKE SURE THE TOOL IS DIS-

CONNECTED FROM THE POWER SOURCE.

1. Loosen the two nuts (B) Fig. 24, approximately 1/4".

Do not remove nuts (B) from shaft (C).

2. While firmly holding spring housing (A) Fig. 24, pull

out housing and rotate it until the boss (D) is engaged

with the next notch on the housing. Turn the housing

counterclockwise to increase and clockwise to de-

crease spring tension. Then tighten the two nuts (B) to

hold the housing in place. IMPORTANT: Inside nut (B)

should not contact spring housing (A) when tight.

removed. Loosen table locking bolt (D), tilt table to the

will automatically position the table surface at 90

degrees to the spindle.

4. A tilt scale (E) Fig. 23, is provided on the table

bracket casting to indicate the degree of tilt. A witness

line and zero mark (F) are also provided on the table to

line up with the scale (E).
