3.4.4.2 Routing the Lifter Cable
0023-7288
1) Check to be sure that the lifter driver shaft [1] and the lifter [2] are fixed
in place by the 2 hex screwdrivers [4] and a hex wrench [3] or the like.
2) Secure the 4 cable fixing plates [5] in place to the lifter using 2 screws
each.
3) Hook the lifter cable [6] on the 4 pulleys [7].
4) Hook the ball of the lifter cable on the 2 pulleys found at the front/rear of
the lifter drive shaft; then, wind the cable about 1.5 times along the groove
of the pulley.
At this time, see to it that the lifter cable is taut just enough to lift the long
screwdrivers used to keep the lifter in place.
5) Secure the 2 pulleys [5] in place to the lifer drive shaft using a set screw
[9] (1 each).
6) After mounting all pulleys you have removed to the lifter drive shaft,
measure the height A from the base plate of the compartment to the top
surface of the lifter at several points, thereby making sure that the lifter is
level.
