SAFETY OPERATION MAINTENANCESETUP
Adjusting the Spindle Feed Handle Return Torsion Spring
This procedure must be performed only by a qualified technician.
Wear a full face shield during this procedure.
If the Spindle does not return all the way up or moves up
sluggishly, or if it requires too much force to pull down
on the Spindle Feed Handles, the amount of spring
tension on the Spindle Feed Handles can be adjusted.
1. Loosen the Lock Knob on the Depth Stop Collar.
2. Move the Spindle/Chuck assembly
to its uppermost position.
3. Turn the Depth Stop Collar clockwise until it
stops, and tighten the Lock Knob to prevent
the Spindle/Chuck assembly from dropping
during Torsion Spring adjustment.
4. Insert a screwdriver in the lower-front notch
of the Spring Cap (78) to hold it in place.
5. While holding the screwdriver in place, use a
wrench to remove only the outer Nut (77).
6. With the screwdriver still in place, loosen
the remaining (inner) Nut until the
Spring Cap notch disengages from the
Spring Retainer -- about 1/8 inch.
7. Turn the screwdriver counterclockwise and
engage the next Spring Cap notch.
Hold the screwdriver in place.
8. Tighten the inner Nut just enough to
engage the Spring Cap notch.
Note: If this Nut is too tight, it will restrict the up-and-
down movement of the Spindle/Chuck assembly.
9. Remove the screwdriver, pull down on the Spindle
Feed Handles 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 4 through 9.
10. Replace the outer Nut and tighten it on top
of the inner Nut. Do not overtighten.
11. If the up/down movement is restricted,
slightly loosen the inner and outer Nuts,
then retighten only the outer Nut.
