QUILL RETURN SPRING
The quill is equipped with a return spring that pulls the spindle and drill bit
back up to its resting position after release of the feed handles.
It is essentially a spring and a notched housing. The spring has been
properly adjusted at the factory and should not need readjustment unless
absolutely necessary. If required, it can be adjusted as follows:
1. Unplug the drill press.
2. Locate the return spring housing on the left side of the drill press head.
3. Use needle nose pliers or a screwdriver thrust into the loop (s, fig 13) to
hold the spring in place.
4. Loosen the two housing nuts (n. fig 13) approximately 1/4" (6 mm). Do
not remove the nuts from the threaded shaft.
5. While holding tightly to the spring housing (h, fig 13), carefully pull it out
until it clears the raised notch (r, fig 13).
6. Turn it until the next notch in the housing is engaged by the raised
notch.
• To increase the tension, turn it counter-clockwise.
• To decrease the tension, turn it clockwise.
7. Tighten the two housing nuts.
CAUTION: Do not overtighten the two nuts. If the nuts are tightened
too much, the movement of the spindle and feed handles will be
restricted.
WARNING! Never use flammable or combustible solvents around tools.
WARNING! To reduce the risk of injury, electric shock and damage to
the tool, never immerse your tool in liquid or allow liquid to flow inside the
tool.
