DUSTLESS LOADING/SELF-CONTAINED DUSTLESS LOADING SPOUTS
MAINTENANCE RECOMMENDATIONS

10. Lower the spout to the extended position, and verify the sleeve is straight. It is particularly
important that the sleeve have no twists. Tighten the lower sleeve retaining bolts, applying
Loctite 243 (567 for stainless steel applications).
6.11 SHORTENING OF TRAVEL
!!! 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.
GENERAL NOTE:
Typically, removing each cone decreases the retracted height by 2 inches and reduces
the extended height by 14 inches; however, this is not true of all models. Refer to the provided drawings for
detailed information.
1. Raise the spout to its retracted position. Loosen the screws that hold the outer sleeve assembly
into the upper housing assembly. Disconnect the sleeve from the housing assembly by loosening
the retaining bolts and let it rest on the outlet assembly.
!!! WARNING !!!
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.
2. Reach inside the housing assembly and remove the three cone support cables by disconnecting
the cone shackle from the lug. This will allow the cones to rest on the outlet assembly.
3. Lower the spout until it rests on a work platform or some type of support, approximately halfway
through its travel. Do not work on the spout while the weight of the unit is supported on the three lift
cables. Also, do not lower the spout to its full extended position while making these changes.
4. At this time, disconnect the three outside lift cables from the outlet assembly. This will allow the
outlet assembly, stacking cones, and outer sleeve to be lowered without unbolting the housing
assembly.
5. Remove the stacking cone assembly from the outlet assembly by loosening the cable clamps that
hold the cone support cables to the outlet assembly. Be sure to make a note of how much cable is
extended past the last stacking cone tab to the outlet cone. This is important so that when you start
removing cones and cutting cables, you have enough left over to reattach to the outlet cone.
6. Remove the required number of stacking cones from the bottom of the stack to get the desired
travel.
7. The outer sleeve must also be shortened. To do this, loosen the screws that hold the outer sleeve
assembly into the outlet assembly. Remove the sleeve from the outlet assembly noting its
orientation. Cut off two sections from the bottom for every cone that is removed. For example, if
you removed one cone, you would stretch the outer sleeve assembly and cut the sleeve at the
