Adjusting the Feed Wheel Return Tension
Spring
CAUTION! Wear an ANSI-approved full
face shield during this procedure.
1. Move the Chuck to its uppermost
position.
2. Loosen Hex Nuts (31) and move both to
the lowermost position.
This will keep the Chuck from falling
during this adjustment.
3. Insert a screwdriver in the lower-front
notch of the Spring Cap (29).
Hold it in place and, using a wrench,
remove the (outer) Hex Nut (30) only.
4. With the screwdriver still in place, loosen
the (inner) Hex Nut (30) until the Spring
Cap notch disengages from the Spring
Retainer (27) -- about 1/8 inch.

Turn the screwdriver counterclockwise
and engage the next Spring Cap notch.
Leave the screwdriver in place.
6. 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.
7. Loosen and screw the Hex Nuts (31) to
the top of the Stop Rod (B12).
8. 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.
9. Replace the (outer) Hex Nut and tighten
on top of the (inner) Hex Nut.
Do not overtighten.
10. If the (up/down) movement is restricted,
slightly loosen the (inner) Hex Nut, and
retighten the (outer) Hex Nut.
