Action
Move the carriage to one end and open the covers
on the outside bend.
Check that the cables are in the neutral axis
(center line of the link) of the chain as shown in
the figure.
If cables are found to be too loose or too tight then
they need to be adjusted.
Repeat the check of the cables in the neutral axis
with the carriage in the middle and at the other
end.
Make an overall inspection of the cables.
If a cable is found to corkscrew it needs to be re-
placed immediately.
If cables have worn through the outer cover they
must be replaced.
Some dust can be expected from the cables as
they rub against the dividers in the chain.
Action
Check that strapping is in place. Each cable is required to be indi-
vidually strapped down, and not bunched together.
If insufficient holes are available in the connection plates for indi-
vidual strapping with cable ties, the cables should be secured in
such a way that they cannot move.
Only use heavy duty cable ties, specified in
on page 188. If strapping has been replaced ensure that a paint
pen is used to mark both sides of the cable tie.
Action
Check bolts and screws on the attaching plates
and brackets. If found to be loose they need to be
removed, have locking liquid applied to them and
then be refitted and tightened.
