The use of accessories and attachments not recommended by Delta may result in risk of injury.
IMPORTANT: When the workpiece (A) Fig. 33 is long
enough, position it on the table with one end against the
left side of the column (B) to prevent the workpiece from
rotating. If it is not possible to support the workpiece
against the column, clamp the workpiece to the table.
ADJUSTING SPINDLE RETURN SPRING
The spindle will automatically return slowly to its upper position when the handle is released. The spindle return spring
was properly adjusted at the factory. However, to adjust, if necessary:
1. Loosen the nuts (B) and (E) Fig. 31. Make sure that the spring housing (A) remains engaged with head casting (C).
2. While firmly holding the spring housing (A) Fig. 32, pull out the housing and rotate it (counter-clockwise to
increase or clockwise to decrease the spring tension) until the boss (D) is engaged with the next notch on the
housing. Turn the nut (E) until it contacts the spring housing (A), then back the nut (E) out 1/4 turn from the spring
housing (A). Tighten the nut (B) against the nut (E) to hold the housing in place.
IMPORTANT: The inside nut (E) should not contact spring housing (A) when tightened.
