Figure 38. Loosening cover and jam nut
3. While holding the spring lock cover against
the side of the headstock so the cover stays
splined with the locking lug; loosen the jam
nut and loosen the cover nut approximately
1 ⁄
4
" (see Figure 38).
4. Put on heavy leather gloves to protect your
hands from possible lacerations if the spring
uncoils during the next step.
5. Pull the cover outward just enough to
disengage the spring-cover lock slot from the
locking lug.
Note: It is important to keep a
good grip during this step. Letting go of the
cover will cause the spring to rapidly uncoil.
6. Rotate the cover counterclockwise to increase
spring tension, or let the cover slowly unwind
in the clockwise direction to reduce spring
tension.
7. Engage the next available spring-cover lock
slot with the locking lug and hold the spring
lock cover tightly against the side of the
headstock.
8. Snug the cover nut against the spring cover
just until the nut stops, and then back off
the nut approximately
1 ⁄
3
turn, or just enough
so there is no binding at complete spindle
travel.
9. Hold the cover nut and tighten the jam nut
against the cover nut.
A high tension coiled spring is underneath
the cover. Put on heavy leather gloves to
protect yours hands from possible lacera-
tions when removing the cover.
