Appendix E Replacing The Constant Force Spring
WARNING The constant force spring is a high tension spring. To avoid pinching
your fingers, coil the spring slowly and carefully. Do not let the spring
twist or crimp.
3. Remove the shoulder screw and large washer from the constant force
spring and drum. Let the spring coil itself up until it reaches the screw that
secures it to the vertical rail. (Figure 87.)
4. Firmly gripping the spring and drum, remove the screw securing the
spring to the vertical rail. (Figure 87.)

5. Lift the loose end of the constant force spring and let it curl up on the
outside of the remaining spring and drum. (Figure 88.)
6. While holding the drum tightly, continue to curl the spring until it is
completely unwound from the drum. (Figure 88.)
7. To install a new constant force spring, reverse the steps of this procedure.
