DRILLING HOLES
TO DEPTH
Where a number of holes are to be drilled to exactly the same depth, a depth stop is provided in the pinion shaft housing and is used as follows:
1.Loosen lock screw (A) Fig. 23, and rotate housing
(B)until the pointer (C) lines up with the desired depth indicated on scale (D). Then tighten lock screw (A).
2.All holes will then be drilled to the exact depth as indicated on scale (D) Fig. 23. NOTE: Scale (D) is calibrated in both inches and metric.
ADJUSTING SPINDLE
RETURN SPRING
For the purpose of automatically returning the spindle upward after a hole has been drilled, a spindle return spring is provided in the spring housing (A) Fig. 24. 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:
1.DISCONNECT THE DRILL PRESS FROM THE POWER SOURCE.
2.Loosen the two nuts (B) Fig. 24, approximately 1/4". Do not remove nuts (B) from shaft (C).
3.While firmly holding spring housing (A) Fig. 25, 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 decrease 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.
