3. With the screwdriver still in place, loosen the (inner) Hex Nut (7) until the Cap Spring
notch disengages from the Spring Retainer (10) -- about 1/8 inch.
4. Turn the screwdriver counterclockwise and engage the next Cap Spring notch.
Leave the screwdriver in place.
5. Tighten the (inner) Hex Nut just enough to engage the
notch.
If this Hex Nut is too tight, it will restrict (up and down)
Chuck-Spindle movement.
6. Pull the Feed Knob and check the spring tension,
making sure the up movement is smooth and
complete.
From one inch down, the Chuck should return to its
uppermost position. If more tension is required, repeat
steps.
7. Replace the (outer) Hex Nut (7) and tighten on top of
the (inner) Hex Nut. Do not overtighten.
8. If the (up/down) movement is restricted, slightly loosen the (inner) Hex Nut, and
retighten the (outer) Hex Nut.
