A high tension coiled spring is underneath the cover. Put on heavy leather gloves to protect yours hands from possible injury when removing the cover.

Figure 29. Loosening cover and cap screw.

3.Put on heavy leather gloves to protect your hands from possible injury if the spring uncoils during the next step.

4.While holding the spring lock cover against the side of the head stock so the cover stays splined with the locking lug; loosen the cap screw approximately 14" (see Figure 29).

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, which could cause serious injury!

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 cover tightly against the side of the head stock.

8.Tighten the lock nut against the spring cover just until the cap screw stops, and then back off the cap screw approximately 13 turn, or just enough so there is no binding at complete spindle travel.
