Method 2:
Move the close assembly arm fully to the right.
Remove the top halves of the belt infeed and exit guides using the knurled screws (screwdriver slots are
provided if necessary). Ensure the correct guides are fitted for the cable (see appendix 1)
Select the appropriate split cable seal (see appendix 1) and position it round the cable.
Take the cable and simultaneously place it into the microduct in the air box and thread it through the
gaps in the belts guards and between the belts. Ensure the cable seal seats in the appropriate groove in
the seal housing.
Replace the top halves of the belt infeed and exit guides.
Close the air box
Prepare the machine to install the cable in the microduct.
Setting the clamp force:
Close the drive roller assembly onto the cable as follows:
The photo shows the drive roller close thumb screw slightly
loosened. (The assembly is free to move).
This thumb screw is attached to the clamp arm lever.
The clamp arm lever controls the position of the roller as-
sembly.
As the clamp arm is moved around the arc the belts move
together and apart.
When the clamp arm is furthest to the right, the gap be-
tween the belts is at a maximum. And vice versa.
When preparing the machine to insert the cable, the clamp
arm is positioned at its furthest point to the right (rollers
open). Once the cable has been positioned in the machine the rollers must be closed on the cable in order
to drive the cable. (And to stop the cable being dragged back out of the machine by any tension in the ca-
ble).
The amount of pressure on the cable can be varied simply by loosening the thumb nut, moving the clamp
arm lever to the right or left; as required, and tightening the thumbscrew.
As more experience is gained using the machine, the amount of compression required will become clear.
Note:
An alternative method of setting the compression force is detailed in the note at the end of Appendix 2.
