4. Attach the new cone to the cable clamps. Apply Loctite 243 (567 for stainless steel

6.8.2 Intermediate Cone Replacement/Inspection (Upper Half)
!!! WARNING !!!
This procedure requires that the unit be moved between its retracted and extended positions.
Before repositioning the unit, ensure that all personnel are standing clear of the unit. After
repositioning of the unit, fully isolate the unit from all power sources.
Take all appropriate precautions for working on equipment suspended from overhead. Failure to
take prudent safety measures can result in serious injury or death.
On dustless loading spout units with lengths greater than 8 feet, the dust sleeve becomes quite
heavy. Special handling consideration must be given to the dust sleeve when performing this
maintenance.
1. Raise the spout to its retracted (full-up) position. Loosen the bolts retaining the dust
sleeve.
NOTE:
AT THIS POINT THE DUST SLEEVE AND STIFFENING RINGS WILL DROP.
IT IS IMPORTANT THAT DUE CONSIDERATION BE GIVEN TO THIS FOR SAFETY!!
2. Lower the spout to expose the cones in the upper section of the DLS.
3. To replace a cone, disconnect the U-bolt cable clamps from the cone(s) and remove the
cone(s). Leave the clamps attached to the cables.
4. Attach the new cone to the cable clamps. Apply Loctite 243 (567 for stainless steel
applications) to the threads before tightening the nuts.
5.
Raise the outlet assembly until the sleeve can be connected to the housing assembly.
Insert the top ring into the tub on the housing assembly. Apply Loctite 243 (567 for
stainless steel applications) to the retaining bolts and tighten.
NOTE
: It may be necessary to push the seal material in with a flathead screwdriver or
similar tool, as it has a tendency to bulge out of the tub.
6.9 CABLE INSPECTION AND REPLACEMENT
An inspection of the lift cables and cone support cables should take place every 90 days to minimize
maintenance costs and ensure safe operation.
