3-9.2. CONTROL UNIT AND LINKAGE - MAINTENANCE INSTRUCTIONS (Cont).
Installation-Control Cable (Cont)
Control cables are precision equipment and should be handled with care. They
should not be bent sharply, twisted, or forced into position. They should be
allowed to adjust themselves to a given installation and worked into position
rather than forced.
The control cable is shipped in a figure 8 shape with sufficient number of layers
to take care of its length. The whole package should be lifted out and laid on a
smooth open surface. Cut the restraining ropes and - holding the top end - walk
away from the package until the cable is straightened out. The cable should
unfold smoothly and evenly. However, if a kink or loop develops, stop and
uncoil this section. When the control is out straight, lift one end up about 4 feet
and walk along handing the cable through your hands, keeping it about 4 feet off
the deck, until the other end is reached. This removes internal twists and gives
the cable full flexibility.
Never force cable into any position. Let it take its natural shape by shaking it
gently before and during operation. Be sure not to bend flexible parts of cable
where it joins the rigid end fitting. Allow an inch or more to remain straight
before starting bend. When installing articulator fittings, DO NOT twist end rod.
