7) Press the “UP” button on the Pendant to wind the Wire Rope onto the Drum. Tightly wind about 5-10 turns onto
the drum (see Figure 6-8 ). Let the rope run through a greased rag. See Section 6.1 for grease type.
8) Without loosening the tension on the Wire Rope, clamp a weight onto the Wire Rope below the Rope Guide,
taking care not to damage the Wire Rope. Replacing the manual tension with the weight will prevent the Wire
Rope from unrolling off the Drum.
9) Fit the rope guide:
 Grease thread and rope guide groove thoroughly.
 Place the half-ring (1) with the short window section onto the rope drum next to the last rope winding
so that the rope exits from the region of the window (x) (see Figure 6-10 ).
 Push rope tensioning spring (2) into the guide groove of the half-ring (1) and hook the ends of the
spring together (see Figure 6-11 ). The special spring tool will make this easier (see “a” in Figure 6-12 ).
 Place the second half-ring (3) with the long rope exit window on the rope drum so that the rope exits
from the drum groove through the window straight and without kinking. The second half-ring must lie
flush against the first (see
Figure 6-13 ).
 Bolt the two half-rings together with pressure screws and bolts (5) (see Figure 6-13 ).
 The rope guide must rest lightly on the drum and be able to be turned by hand. If this is not the
case the guide has been fitted incorrectly or the rope drum is damaged.
 Bolt stop with bearing and conical spring washer (6) to the rope guide (see Figure 6-14 ).
 Bolt on protective plate (8) (see Figure 6-15 ).
